Creating A Tiny, Free, Roaming Webcam?

Cliff posted more than 13 years ago | from the your-own-home-videos-direct-to-the-internet dept.

Hardware 163

vitus979 asks: "Every year there is a big 7 day bicycle ride in Iowa called RAGBRAI (Register's Annual Great Bike Ride Across Iowa), and an interesting problem was put in front of me and I'm looking for the best solution: make an extremely lightweight, self-contained webcam system fully independent of a base station, but yet able to upload pics to a file server from nearly any location in the state of Iowa to be shown on a website in realtime."

"I thought it would be cool to mount a webcam on my bike when I go this July. I looked around on the web and the only similar implementations I could find included a bike trailer and 20lbs worth of computer parts. I know that a person can do better than that. I'll be at least 5 miles from a support van at any time so short range solutions (Bluetooth, 2.4ghz wireless LAN) isn't an option unfortunately. What I'm looking into is a small webcam linked to a PDA with a cellular modem. The webcam takes pictures every couple of minutes and the PDA takes the image, calls on the cell modem, uploads the pic, and disconnects the call. This saves me cellular charges and conserves power so that I don't have to carry a bunch of batteries with me.

Basically I've gotten to the point that I need a firm set of hardware and a good wireless implementation to get the information to the servers. Below is what I will need for the system. Any suggestions for each piece, or a full working system that could be purchased would be very helpful.

Webcam: the smaller and more power efficient the better, something all weather, the size and shape of a pen would be optimal since aerodynamics play a part in this piece and I don't want something like a Logitech QuickCam stuck to my helmet.

Computer: PDA sized or smaller if possible. Needs to be able to connect to both a Webcam and a Cellular Modem and be able to do the work explained above. As power efficient as possible, the longest lasting batteries possible. Needs to fit in bicycling jersey pocket (about 4 inches wide and 8 inches deep).

Modem: this is problematic as not all of Iowa is covered for digital cellular service but all of Iowa IS covered for analog at least. Another option may be the recently reinstated Iridium system (I read somewhere they allowed data transfers)."

SuperDuperMan (257229) | more than 13 years ago | (#388909)

Before you go to the effort and expense of putting something like this together maybe you should figure out if you are even going to have an audience. I doubt that live pictures will be necessary even for those interested in seeing the pictures. Just capture pictures and save them then upload them toa server later. Just because it can be done doesn't mean it should be done.

Palm Pilot (2)

KirTakat (110620) | more than 13 years ago | (#388911)

Okay, I can't find the information right now, but I know that best buy used to sell a Palm Pilot camera, maybe something like that, on a palm VIIx would provide the solution. As for the aerodynamics of it, I would suggest strapping it to your chest w/ the lens tilted upwards. Now then, for the calling and disconnecting you might need to do a bit of search for software that can do it, or even possibly writing it yourself if you know how. Sorry I can't be more discreptive.

The data transfer is the hard part, but you could do it with a small linux PC like some of the posts last week, running off a Nightrider type battery in the Bottle cage. Some of these brick type computers have big harddrives, and you could just spool and forward when you can. has some cool mini cams that can run on USB, and could fit wedged in a helmet vent.

Do you know what RAGBRAI is? Have you ever been on it? The idea of getting away from it and unplugging on RAGBRAI is laughable. Over 10,000 people on bikes, plus a few thousand more driving vans, bike store employees, etc. It's on the front page of the Des Moines Register (the "R" in RAGBRAI) every day for a week. This is just one more step in the media coverage of the event.

*My* ideal solution (5)

Raptor CK (10482) | more than 13 years ago | (#388915)

You should look into PC/104 and other miniaturized PC systems for this. All you'll end up needing is USB support for a D-Link camera, and PCMCIA for your modem (only 1 type II if you use the Merlin or Sierra AirCard).

That's only two modules, perhaps just one. There may be other solutions as well that you can look into. Since you don't seem to need video output as well for this, a serial console would be ideal, and you wouldn't need it to be hooked up all the time anyway.

Finally, the disconnect for CDPD will only be needed to save battery power. Most service plans are unlimited service, not per kilobyte, unless you're roaming.

Here's your USB cam:

With proper mounting (think about shockmounting and using a flash chip for storage, it'll be a lot more durable) on the bike frame, the profile will be fairly small.

For even more insanity, you can use an ultralight subnote like a Libretto (with a USB card) or a VAIO PictureBook, depending on OS support. This would be easier to get on short notice, of course, but you'd need someone to supply you with batteries.

Best of luck!

For power, what about a dynamo? (2)

influensa (267570) | more than 13 years ago | (#388916)

Ok, so I'm science stupid, but it my universe this seems like it would be somewhat plausible:

I've seen bike lights that are powered by the motion of some part of the bike (ie. the wheel, or collecting wind motion maybe) so the light is actually being powered by the person, no batteries required. Of course, a PDA and cell phone are going to require a lot more electricty.

But what if the telecom/webcam was working off of a rechargeable battery, that while being drained is also being fed by the motion of the bike, and perhaps also solar power (because any energy collected off of the biker's effort will slow them down I guess).

Realistically, the solar/kinetic battery recharging won't be enough, but it could be enough to keep it running all day until nighttime (or whenever the biker is resting) when it could be plugged into the wall for a complete charge?

Alternative energy rocks!

Ham Radio? (2)

suwain_2 (260792) | more than 13 years ago | (#388922)

Modem: this is problematic as not all of Iowa is covered for digital cellular service but all of Iowa IS covered for analog at least. Another option may be the recently reinstated Iridium system (I read somewhere they allowed data transfers)."

There's always ham radio... This, of course, requires that you obtain a valid license. But in the ham community, your request wouldn't be at all unusual.

However, another problem is that if you plan on mass-producing this, you'd need to force everyone who will use it to get a license before they can legally use it.

Here's another solution. Put a fairly good amount of storage capacity in it. If the cellular modem is out of range, it will save the image, and try again in a couple minutes. It will continue this until it can transmit the saved images. In the event that it runs out of space, it will delete every other one, or something to that effect. (Doing every other image ensures that the timing is consistent between pictures.)

Why not? put some bikes on the track, take some pictures previously (storing localy), and then, during the event, say that they are live! Don't forget to use small, blury images or else it won't work so nice. It is also wise to say that you use a patented technoloy when asked, to justify the fact that you can't explain the technical aspects :)

Re:*My* ideal solution (2)

suwain_2 (260792) | more than 13 years ago | (#388929)

Hmm... Sounds good.

What I still want to know is how you're going to be taking the images. I'd tend to think that they would come out blurry unless it took a *very* quick image. Plus, if you were turning, it would be even worse.

I personally would give this some consideration before proceeding, as I'd hate for you to spend months making a super-cool camera, and then have every single image come out blurry...

As a former Register employee, and knowing the way they're crazy about drumming up RAGBRAI press, I'm sure you might get some interest.

Re:For power, what about a dynamo? (1)

suwain_2 (260792) | more than 13 years ago | (#388935)

You may be "science stupid", but you've got a good idea!

Now, I'm car stupid, but don't cars charge their battery off of the movement of the axle, or something to that effect? I've seen exercise bikes hooked up to power a 6x6 panel of 100 Watt lightbulbs; I think you should have more than enough power to run a small camera and a cellular modem. I don't know that you would *need* the battery, although it would be foolish not to have one -- suppose you stopped for a minute.

Now, the one issue is that if you're racing or anything, it may require a little extra effort. (Maybe not)

Leave the computing to the support team maybe? (2)

Aggrazel (13616) | more than 13 years ago | (#388936)

Well, I'm thinking, everyone that I see so far has wanted to put a small computer on your bike.

But I think it would be more efficient, since like you say, to have just a small wireless camera and leave the PC equipment and the web page uploading and whatnot on your support vehicle.

A quick web search on wireless cameras turned up this:

I don't know if this works (its 2.4ghz, I don't know what your problem is with bluelan), but I'm sure that there are similar products out there.

Just a thought.

My recommendation--requires about $1500 (2)

Xeger (20906) | more than 13 years ago | (#388937)

You've got three resources you need to be carrying with you on the bike: network connectivity, processing (CPU) power and electrical power.

The network connectivity is the easiest: get a cellular phone with CDPD (Cellular Digital Packet Data) or GSM data service. Most cell phones come equipped with an IR port or a serial port attachment so you can connect the phone to an IrDA or serial-capable device and use it as a wireless modem. GSM phones are probably your best bet, since they're most standardized. Check with different cellular service providers to see if any of them cover the entire state of Iowa. I know AT&T does, but they use TDMA which isn't as good as GSM.

Next, you'll need a computer, with webcam, to hook this phone to. Your options here are: buy an iPAQ handheld for $500 (if you can get your hands on one!), or buy a Sony Vaio mini-notebook for $2500 (weighs less than a pound, about the size of a portable CD player)

If you can get hold of an iPAQ, it should suffice nicely. Your challenge will then be to connect a webcam to the iPAQ. The iPAQ has a USB port, so any USB webcam will do; the problem will be finding Windows CE drivers for the webcam. You can install an experimental version of Linux on your iPAQ, courtesy of the Compaq research team. Under Linux it should be a snap to use one of the Linux video APIs to capture frames from the webcam. Your cell phone's data link will also work under Linux, via the iPAQ's IrDA port. To find out how to install Linux on an iPAQ, check out the howto: le/install.html. The advantages of an iPAQ are that it's small, very light, and has a comparatively long battery life. If you shut the display off, a single battery charge should last you 24 hours.

The Sony Vaio is an x86 machine AND it has a camera built into the case, so it's a no-brainer to get a webcam working with it, out of the box. The problems with it are its price and its battery life: even with the display off, the battery isn't going to last longer than six hours. If you buy a VAIO, you'll either need to carry along some spare batteries, rig some sort of generator for it, or stop frequently for recharges.

A final note: a continuous cellular data connection can be pretty durned expensive. Expect $0.15 per minute of use; even if you only connect when you're using the service, you'll be spending at least $5 / day on webcam updates.

Watch out for analog modems (1)

smurd (48976) | more than 13 years ago | (#388938)

I did something similar in another life. We needed to digitize 4 still images and send it through an analog cell phone. Make sure you turn off the error correction internal to the modem, then write your own packet driver that accepts packets in any order and acks each one. You are going to get "stored fragment 'o packet" from the cell, so make sure you ignore incomplete packets.

It's a mess and its slow (1200 to 2400 baud was the best we got)

You can also try using amateur radio packet, If this option is available, use it! You probably won't get great coverage but it least you get to stay digital and don't have to worry about modem compression and correction.

Good luck

Use a dynamo (2)

Stavr0 (35032) | more than 13 years ago | (#388939)

Use a wheel dynamo, and a smallish solar panel while you're at it. It would alleviate the problem of carrying spare or high capacity batteries. Just one set being continually replenished should work just fine. Put the solar panels on your cycling cap!

The Bastard (25271) | more than 13 years ago | (#388946)

Most of the wireless solutions available for Palm/Handspring/etc devices utilize CDPD (cellular packet data protocol) for network connectivity. Problem is, Iowa (save for pockets of englightment) doesn't really have much CDPD coverage.

The serial line to analog cell phone might work (unless you are along a major Interstate in eastern Iowa, or in a major metro area, forget digital coverage). A link for something along this line can be found here [] .

I'm working on something vaguely similar to this as part of my Embedded Linux Challenge entry...

Using a PC-104 device, supplied by ELJ, I'm making use of two radio transceivers... They have a data rate of 56k (though I believe you can purchace higher-data-rate modules) and range of, get this, 40 km, line-of-sight. We're currently doing testing to ascertain the range without line-of-sight in various situations (city, suburbs, woods, etc) so I can't comment on how well they do, though 5 miles should be plenty close to maintain the full data rate...

They can connect using a "developers'" board that contains an RS-232 chip, and some status LEDs... quite cool, all told. They run on 5-12 VDC, so batteries are certainly an option.

They're made by World Wireless Communications [] . IIRC, they cost us something like $400/piece. Look into 'em.

vizshun67 (69071) | more than 13 years ago | (#388950)

First, perhaps instead of making use of the batteries exclusively, you could hook a generator to the bike. The generator could be used to charge the batteries where you have 2 sets and you alternate between charge and use/expend.

Secondly, I would refer you to all of the embedded linux solutions: check out:

A lot of manufacturers make PC compatible single board computers (some very small) that will run Linux. The Basic STAMP micro-controllers might not be a bad choice either, they come with a lot of accessories (such as a mini-webserver) and a lot of hobbyist work with them: check out:

Lastly, I would refer you to Information Unlimited at:

to get a small, low cost CCD camera, assuming that you didn't want to go with one of the cheapy webcams out there.

As you might be able to surmise, I have given thought to the kind of project you describe (hobbyist robotics actually). I don't really have THE answer for you, but these are some good places to look. I hope this helps.

the connectivity part is very easy. (5)

daniell (78495) | more than 13 years ago | (#388951)

its surprising how easy the connectivity part is: A samsung sprint pcs modem has a serial port and is a modem; just put a modem where you want to connect to (or use a more costly ISP) and dial up. Then transfer the file and disconnect. The samsung 8500 has a special serial cable just for hooking directly up to a palm V. no costly PDA modem needed. This is also largly true of GSM modems (the omnipoint ones here, like that nokia dual band thing).

I was told once, and I now think it a lie, that GSM worked by communicating to low orbit satellites and hence was global. I don't know if that's true, but I'd hope that either sprint pcs, or GSM would be widely available over the entirety of your course.

Don't ask about the camera, I wouldn't really suggest that sony picture book. But the cam for the clie is no longer an option it seems; and things like this [] never seem to be real. Although the visor eye module [] may be what you'd want in that case.

Try this one for size [] . With a resolution of 330 TV lines and a 9- to 12-volt line drawing 150 milliamps, this one sounds pretty good. Of course, it'll need some sort of battery pack and transmitter. It isn't the one-piece setup he was looking for, but this will do just fine.

Kenwood VC-1 may be an option (2)

n8ur (230546) | more than 13 years ago | (#388958)

Kenwood makes a webcam-like device called the "Visual Communicator 1" (VC-1) that converts the picture to audio tones which can be sent via a two-way voice radio (like a business band radio). It was really designed for ham radio use, but there's no reason you couldn't use it on a business system if the other users would put up with hearing the warbling audio tone for thirty seconds or so each time a picture was transmitted. The pictures can be decoded and saved as .jpg or whatever using software that runs on a laptop hooked to a radio receiver.

It's quite small -- it looks like an overgrown hand-held radio microphone and the picture quality is "decent" but not spectacular. It costs somewhere between $200 and $300.

Depending on the system used the range could be in several ten's of miles (particularly if there's a "repeater" on the radio system).

Have you ever thought about using a radio modem to a chase vehicle? When I was working on my school's solar car project in 1995, we had a van loaded with various telemetry equiptment, including a radio modem connection to the car, so that we could get speed, battery consumption, etc.

I don't know enough about your race, but with a power inverter, a few space car batteries, and someone willing to follow you in a car, this wouldn't be that hard to pull off.

[If, however, the race route is completely closed off to vehicles, this would be more difficult].

You might also look into other forms of communication. Check to see if Metricom [] has access in our area, or someone like them. [I haven't had one of their modems since '97, but the modem at that time had a battery which lasted me a good 3-4 hrs of constant use.]

With the chase vehicle concept, you might also try looking at X10 [] gear, but I don't know what their power consumption is.

Re:For power, what about a dynamo? (1)

boristdog (133725) | more than 13 years ago | (#388961)

I don't see why a palm cam with a cell phone modem couldn't be powered by a solar cell. What do you think the energy density of those 4 AAA batteries is, anyway? 'Tain't much. A small generator would also work fine, but those little bastards add a lot of effort to your pedaling. Why not just a D battery adapter for the palm & cell? Have someone give you a new set every 6 or 8 hours. Or run the whole thing off a motorcycle battery (~10lbs for a small one) which should last all damn day.

X10 (1)

JediTrainer (314273) | more than 13 years ago | (#388962)

I originally thought of the X10 camera when I read this post. I bought one a few months ago, and I love it. It's a fantastic little device and it has a pretty decent range (approx 100'). Unfortunately, 100 feet is a far cry from 5 miles to the support vehicle, so there's still the problem of how to upload the images to the base station. Obviously there's no point in using the wireless camera if you have to carry the base station with you too. So while the camera's good, we still need to figure out where to keep the base station in order for this to be useful. Otherwise, I'd suggest to get one of those USB devices and plug it into a handheld with a cell modem.

Re:For power, what about a dynamo? (2)

CodeShark (17400) | more than 13 years ago | (#388964)

No, cars charge their batteries via an alternator, which is driven by the engine via a rubber belt.

As far as using a dynamo on the wheel, it wouldn't work really well because in most cases the voltage fluctuates too much based on the rider's speed, thus requiring additional electrical conditioning equipment and weight, and would in all probability tire the rider out very quickly if he/she intended to keep the whole setup powered throughout the day.

The best probably power scenario is for a small solar panel (30cm^2 or so) positioned relative to the bike's motion to provide a minimum amount of drag.

Palm VII and PalmPix (1)

carpoon (159339) | more than 13 years ago | (#388965)

What about a Palm VII and Palmpix camera? I am sure it wouldn't be difficult to set up a script that will take a picture and dial the modem every couple of minutes. An unlimited cell account for the Palm VII only costs $45. You may have to swap out batteries, but this seems like it would be a light, relatively inexpensive solution, that you could probably convince Staples or somebody to donate the equipment for.

Subnote w/ built-in camera (1)

kylepike (304383) | more than 13 years ago | (#388966)

I am one of the people interested in seeing these photos.

I think I remember a similar story from SF's Critical Mass, but IIRC they just uploaded all the pics after it was over.

There are 2 Sony sub-notebooks with built-in cameras, the Picturebook and the new GT1. The GT1, in particular, seems like it could work if you figured out a good mounting solution. It has a nice cam, 17 hours battery life, full motion video, a type II PCMCIA slot, etc. It's really a camcorder with a PC built in - not the other way around.

More info, and US purchase, is available here [] : for the timid.

Also the newest Libretto and another of the japan-market subnotes (a fujitsu I think) have built in cameras. I would have more info, but it seems like Japan Palmtop Direct,, has gone down/out of business. They used to be the best source for JPN market notebooks.

Dynamism has the Libretto, and its' built-in "lipstick camera" is removable, which the sonys are not. But it only has a 3.2 GB Hd.

Dynamism might actually ship you one of these units for free, if you get your colleagues at the Register's tech department to request it...

There is a visor cam available, and a palm pilot camera, but the problem is there's not an easy way to hook both a camera and a cellular modem up to a PDA. That, to me, is the biggest prob with the Visor and its Springboard slot - you cannot daisy-chain springboard modules. No way to use wireless, camera and flash memory in one system concurrently.

Now if there is a camera available for the Palm VII, and there is Mobitex service in the area, that might work. (FYI any device that says it'll work with a III should work with a VII)

Otherwise, you might be stuck trying to build a single-purpose PC, or you might have to upload pics at intervals when you stop.

Re:HAM (2)

suwain_2 (260792) | more than 13 years ago | (#388968)

I'm a ham radio operator myself, figured I'd explain a bit.

First, "HAM" doens't have to be in all caps. This is a common misconception, I guess... I don't know any hams who capitalize it "HAM". (A similar phenomonen occurs with people who don't use Linux, and label it as "LINUX") It's not really *wrong*, it's just a pet peeve of mine.

Anyway, another misconception is that ham radio always goes around the world. It depends on a number of factors, but the fact is that a common ham radio handheld will not go around the world. However, "repeater" sites are very common -- they repeat your signal at a much higher power, from a great location. Thus, a user on a low-powered "HT" (handheld) could still have his voice heard for hundreds of miles.

I have never actually used packet, but it is possible to achieve great distances with this, also.

One additional note... You will, of course, need a license to transmit. And you can't use it for commercial purposes.

Yaesu [] has just come out with nifty new "rig", the FT-817 [] . This little radio transmits on the "HF" ('shortwave') bands, and can, theoretically, be heard anywhere in the world.

Also, PSK31 is extremely popular. I don't know about using it for images; I'm not in a position to comment on it. I don't know if they have an official site, but [] is a very informative site.

For those interested, here are a few additional ham-radio related links.

Non-real time solution (2)

ptomblin (1378) | more than 13 years ago | (#388969)

Get an ordinary digital camera that takes pictures onto removable media, such as CF or memory sticks. Get a couple of these media. Every once in a while have your support people drive up and hand you one CF/stick while you hand them back the one you've just filled up with pictures. Let them worry about uploading the pictures to the web.

This solution means that you no longer have size/weight/power restraints on the computer and communications equipment doing the uploading to the net, which should make things cheaper and easier.

If you've got the budget for it, you might prefer two cameras to swap back and forth rather than trying to fiddle with CF cards while riding at high speed.

Both the LART and Ricochet should only weigh a few pounds.

I'd first like to thank the slashdot guys for posting this. Here are some of the things I've done since I sent them the original message. Second of all I work for the Register, so if this goes through hopefully I'll be able to ride RAGBRAI and not take vacation time for it. :)

I actually haven't found a digital camera that'll fit my requirements so I'm looking into an analog camera with an analog-USB adapter.

I'm looking at the:

SuperCircuits pc75wr analog camera -->

and the Belkin analog -> USB converter -->

I'll admit it and get flamed here, but I haven't looked through the embedded Linux stuff on the web, but from looking at Palms, Handsprings, IPaqs, and Casio's line I haven't been able to find a handheld that will do both a USB connection and a PCMCIA cellular modem connection at the same time. I think I found my computer base unit. It also includes a built in GPS system so if things go right there might be a map beside the picture with a big star that shows where the rider currently is on the route.

Modem: I recently found out that one of the cell phone companies also helps to sponsor RAGBRAI so I might be able to swing a sponsorship for this portion.

I talked with a gentleman at MIT in the wearable computer club and the consensus is to be careful and get shock-resistant parts since I'll be on the bike.

Keep the suggestions coming, the more the better. (I don't want to use up my vacation to go on RAGBRAI!!) :)

It's not necessary to see live pictures on Jennicam, either, but I doubt it'd get the same audience if the pictures were taken ahead of time and presented in a big lump at the first of every month.

This is a really cool idea for a webcam, just because it's something different, and in the world of webcams, different means interesting.

I don't know why I'm responding to an obvious troll, but I think he was actually complaining about the fact that the store bought solutions he saw were 20 lbs and required attaching a trailer to his bike. This seems like an obvious problem since he's going to be on a long distance bike ride.

Also, price doesn't seem like too much of a problem for the poster, since his request for advice mentions he wants as small of a webcam as possible, as well as a small computer that can connect to a webcam and a pda AND a cellular modem. None of these items are free, or even cheap. It seems the reason he wants to develop his own solution to his problem is that the current solutions are not good enough.

You decry this person attempting to create their own solution, rather than throwing money away by purchasing a solution that is not up to their needs. Whatever happened to good ol' fashioned ingenuity? The Do It Yourself ethic? What in the world is wrong with him finding a way to do something on his own? Do you also think it's crazy to work on your own car, rather than overpay a mechanic to work on it for you?

I don't understand your position. What in the world is wrong with figuring something out for yourself and implementing it, as opposed to paying someone to do it for you? What is wrong with him asking for advice on how to solve his problem?

I think you are just using this topic as an inappropriate excuse to sound off about one of your pet peeves. It is inappropriate since this post has little to do with Open Source. He has a hardware problem and is trying to solve it in the best way he can. His solution seems to involve quite a bit of non-Open Source hardware (pda's, cell phones, webcams). If his question was "I need to hook two of my computers together, how do I do it?" would you tell him how to plug the cables in, or use that as another excuse to vent?

Handspring Visor + Eyemodule2 + Cellphone (5)

rwa2 (4391) | more than 13 years ago | (#388981)

I'm surprised no one mentioned this yet... The eyemodule 2 [] plugs right into the visor and can capture 640x480 color. It should come with software that will allow you to dial up to an ISP and email the pictures off. I use comlink and a cell phone with an IRDA modem to connect to the internet (my Visor is more or less my primary computer now, I can use TGssh to log into my friends' computers and do stuff there). So you would need something like the following:
  • Visor Deluxe or Platinum ($250 / $300, 8MB of memory, runs for about 2-6 weeks off a pair of AA batteries) The Prism would let you look at your pictures in color, but has rechargeable batteries, so probably wouldn't work for you. The greyscale Visors seem to be able to store color pictures, though.
  • Eyemodule2 ($200 , you can download the picture emailer program from [] or [] there's also the greyscale eyemodule1 for cheaper some places)
  • cell phone with a modem (~$170 for my little Nokia phone with IRDA. There are Visorphones ($300) and wireless modules for the Visor, but then you'd have to swap modules all the time. For service, I have Voicestream GSM, but that's limited to 9600baud digital service right now... I think TDMA (AT&T, Verizon [] ) networks might let you connect up to 14400baud and have more complete analog roaming).
  • if you want to get fancy, you could spend maybe $100 or so on phone-Visor serial cables so you don't have to hold them together to use the lame IRDA link, so you can keep pedalling while you're connected. Then again, it might be cheaper and more convenient to just duct tape both of them to your handlebars so the IRDA links always work... that way you could use the phone's serial port for a handsfree kit so you can talk to people when you aren't dialed in. A pet peeve of mine with the Nokia phone is that the IRDA port is on the wrong side of the phone, so I have to hold it upside down to use my Visor. But you could probably get creative with a mirror.)
  • you might want to program a script (or get someone else to program a script :) ) to automate the picture grabbing/uploading tasks with one button. I don't think I've seen anything like that yet...
Good luck! Sounds like you're going to have a lot of fun!

N3MCB (30591) | more than 13 years ago | (#388983)

Packet would be way too slow for this, however I would think a fastscan TV signal could be sent back to a base station and then a tv capture card could take the snapshots. The usual TV frequencies for amateurs (technically if the mode is allowed on the band you can use any frequency, but there are voluntay band plans that set specific freq's for various things) align on cable channel 58 (427.25) and 61 or 62 but may differ in your area. The only rules based problem with this is part 97 does not allow broadcasting, so this has to be part of some type of 2-way communication. Both sides don't have to be transmitting video but it can't be soley 1 way.

Get any of the freeware FTP programs (some have timed upload of a specific directory), set the camera for captures every few seconds, and you have yourself a completly isolated webcam the size of (roughly) a PDA.

An alternative which involves a base station would be a video camera with a high range transmitter (a few miles). This could take the signal to a much powerful connection, where you could, say, stream the video...

The only carrier I'm aware of that even comes close to providing digital coverage to all of Iowa is TDMA service from US Cellular [] . I have a phone from them and they really do a good job of providing digital service to even the most rural areas in the state (except for my apartment, grrrr).

Re:You could use fake photos.. (1)

Snowdog (3038) | more than 13 years ago | (#388990)

This could actually get quite entertaining, since for credibility's sake you'd have to add in a script that selects the right pictures to post based on the time of day and the current weather conditions grabbed from NWS.

Then if you really wanted to be anal about it you could pre-program in your route and dynamically query information from MapQuest to decide what kind of terrain the photo should contain for that particular day and time. And if you wanted to get really ambitious, you could periodically do a lookup on addresses in the vicinity and try to include people and buildings in the photos that might fit for those address (i.e. residential, retail, industrial, agricultural, etc).

Given all of the above, I'd have to say that a site with fake photos may well be much more interesting than a site with real photos.

You have to start by looking at the Cam's POV. (5)

CodeShark (17400) | more than 13 years ago | (#388991)

This is a classic case of knowing which problem to solve first, then building a system that doesn't break the solution (to the first problem). What I am getting at is that if you don't consider the camera POV, you might end up with a wonderful system to collect and transmit ultimately worthless pictures in terms of quality. It also almost goes without saying that all of the electronic equipment needs to be suitably protected from bad weather and road dust/muck, etc.

So here's my specs for a cam setup that could get reasonably interesting pictures:

  1. Vibrational stability. No use getting jittery, blurred pix, right?
  2. Aimability. What if the most interesting pic of the moment isn't directly ahead? This might include lens with a moderate amount of wide angle/zoom capability. This could probably be accomplished with a semi-custom tripod head fitting.
  3. To go with aimability, etc. I would add detachability -- in case the bicyle it is mounted on were damaged, the setup could be moved. Secondarily there are many more interesting pix to be had when the riders aren't actually in motion, and finally
  4. Reasonably high resolution and color depth, because even if you are transmitting images live, how many people can watch the whole seven day race? So back at the web server end, and after the race is finished, you want to have better than average pix as a result of all the effort.
All of this says that what you probably want on the handlebars is a fairly decent megapixel camera, probably the one that uses an IBM microdrive -- one I have heard of can store 1500 pictures. (Which would be about one a minute for 12 hours), assuming that the cam uses AA batteries, so that a recharger can takes care of the continued power requirements. Nearly all the good digital cams have USB, so you have an easy connection to the device which will be responsible for image collection and transmission.

Then we have to consider the other end: transmitting the image without a high speed data link. Since high res, high color pix require major bandwidth, the collector has to be able to compress the incoming images, probably resized for web page formatting, and perhaps tagged so that the high res pix from the camera can later be uploaded and replace the lower res image or be available from a thumbnail.

Probably requires more than a PDA. So my vote goes to the smallest Transmeta-powered device capable of the image processing, equipped with a wireless PC-MIA modem of some type. (Clueless about the best communication option here, fellow /.'ers, help me out!) Finally, I would think that a person would need a small solar panel to keep all of the devices and batteries charged, so the Transmeta device would rest just under the solar panel probably on a cushioned rack above the back wheel.

Still weighs alot less than 20 lbs, I would think, and positioned properly shouldn't add that much drag. Best I can do but fellow readers, what do you think?

I own a Dolphin Pencam FastUSB007 [] , whick is approximately as long as a ballpoint pen and about as wide as 2 AA batteries side-by-side. It is USB (you might have to duct-tape the USB plug into the side to keep it attached on a bicycle). The cool thing about it is it functions both as a digital camera (when disattached) and as a webcam (when attached to a computer). It takes 2 AAA batteries and is extremely light (it wouldn't be hard to mount on a bike).

AFAIK, the software only works in Windows, and I had a bit of trouble getting it working. You can use whatever free Webcam software you want (I use ConquerCam I found somewhere - it uploads to a FTP site every 5 seconds or so). The image quality isn't that great - The resolution is very small, in camera mode it needs a substantial amount f light to take the picture, and the videos are rather grainy.

You should be able to find it for around $80. The site I bought it from no longer sells it, but I'm sure it's available elsewhere.

That said, I'll throw out some other notes on systems like this. First, they are flaky, and don't like you moving, so when you get a connection, stop moving. A modem connection seems to be much more fragile when switching between network cells than a phone call is. Second, think redundant. Get multiple paths of connection, because there are so many places where the connection can break down, and you'll go crazy if you absolutely depend on any of them. Lastly, forget about sending up pictures and enjoy the ride. Experiences like that aren't for sharing with other people over the web, they are for experiencing first hand, while it's going on.

I live in Iowa (yeah, computers *do* exist here. Gateway once was based in Iowa, in fact. +1 Informational :P) and think you should actually look into a few things before doing this webcam off a bike during RAGBRAI.

LAN parties are a new thing around here. People are realizing they can connect their computers up in a "little Internet" and play games and share farm porn.

Webcams are currently illegal according to city ordinances in 35 of the 99 counties, so you'll want to turn the puppy off depending on where you're at during particular points of the day.

I went ahead and asked my cousin Darrell what was wrong, but he didn't reply, so I asked my other cousin Darrell whose *the* computer tech up at State University. His response?

"Handheld PDAs r a black market item in Iowa. Y'see, some genius farmboy figured out how to hook the sonsabeetches up to dat der Internet thingny and using some GPSr they can finger out how well their corn be a growing and witcha dem plots a'land needa watering."

Sad thing is, he's right. The college I'm attending is pumping out some decent quality MIS and ComSci/ComE students that end up leaving the state to work places where states welcome business, rather than tax the hell out of them.

So yeah, we might not be a Silicon Valley, but you just wait till the farmers start using some of the agriculutural technology Iowa State University has been working on.

Who needs to genetically modify food when you can grow more in a smaller space due to simple improvements in the layout using the technology you've got?

You're right about the coverage:
voicestream omnipoint [] provides digital in a number of cities, and sprint pcs [] [if the link doesn't work click on learn, coverage, select iowa] don't exactly offer great coverage. However that samsung phone I mentioned does work in analog mode, and I assumed it could still operate as a modem in that mode, although I may be wrong there. The author said that analog was widely available and probably his best bet.

I'm surprised and the US Cellular claims of PCS coverage in comparison to the Sprint PCS claims. I wonder why companies wouldn't mutally negotiate terms for sharing PCS access. Unless PCS is some general term and TDMA and CDMA in no way like one-another.


ps, personally I don't think there's going to be a good solution, and he should abandon the "live" idea and just get a good camera with lots of storage, mount it, take slides, and upload them progressivly at the end of each day using a phone modem.

signals and resetting (1)

This might be kind of a "Duh" post, but be sure that the software has the ability to redial or retry the call, if it cannot find a signal. You do not want to be resetting every 5 minutes because you are in a rural area with no coverage. Even areas that claim 100% coverage can have some nasty spots. Just make sure that the software can handle a fully automatic process, without having any human intervention. Test it out by driving around in your car, but when you do the test just turn it on, and let it run, don't touch a thing. Have a friend monitor the website to make sure it is working.
