A Look At the Firepick Delta Circuit Board Assembler (Video)

Change It has vision! (35 comments)

This project appears to have computer vision for parts alignment, which is a HUGE deal for a pick-and-place. You need your machine to know if a component is oriented improperly in the reel, and to provide positive feedback on board position by referencing fiducials for accurate placement of fine-pitch components. Other pick-and-place projects I've seen in the past have been just standard 3-axis CNC gantries with a vacuum pickup, the addition of CV means it potentially can truly compete with the high-cost units.

Change My CFL lifetime depends on where they were bought (278 comments)

I've bought a number of Feit Electric CFLs from Costco, and get at least a few years of regular use out of them. However, whenever I've bought the same brand from various local hardware stores (both mom-n-pop and big brand stores) I've had them fail within a few months. I'm not sure what's up with that, but that's my experience. I have yet to try any LED bulbs due to the up-front cost and the long life I'm getting out of my CFLs, and I have no use cases where dimming is necessary.

Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

Change External yes, cards no (502 comments)

At work I have a HiFiMeDIY Sabre Tiny USB DAC ($30) as my work laptop's internal audio is full of noise (hissing that changes with system activity).
At home, my gaming machine uses its onboard audio interface, but sends digital audio out via SP/DIF to my home theater receiver for its DAC and amplifier.
I even have an external sound interface for ham radio use, a Tigertronics SignaLink USB that's just an external ADC/DAC with some filtering and isolation which interfaces with my radio for digital modes (such as PSK31 or RTTY).

Interviews: Ask Andrew "bunnie" Huang About Hardware and Hacking

Change Re:I've never heard of you (58 comments)

His book, Hacking the Xbox, is now available for free: http://www.nostarch.com/xboxfr... The chapter on the methods he used to actually bypass the system's boot security was fascinating.

Security DVR + iNet + X10 = Easy Home Automation (Video)

Change Neat idea (25 comments)

I saw this at Maker Faire, he's using an on-screen display generator to produce menus and output that you feed into a video input channel on the DVR, and it intercepts the DVR's RS-485 bus (used for pan-tilt-zoom control of cameras) to receive command input from the user. Pan down is parsed as next menu item down, pan right is "enter", etc. It's quite nifty. The menus are set up for individual X-10 or other commands, and you can even set up multi-event macros.

Remote-Controlled Planes Used For Wildlife Conservation

Change ArduPilot (48 comments)

They're using the DIYDrones ArduPilot, the image in the article shows the ArduPilot Mission Planner software. For a few hundred dollars you can turn an RC aircraft into an autonomous craft, it's a very nifty project.

Change Re:Root? (840 comments)

I too am a fan of root beer. A friend makes his own, but not from the pre-made syrups. He steeps sassafras root (carcinogens be damned!), mint leaves, vanilla, and other tasty ingredients, then filters and carbonates it and lets it rest for a while. My wife refers to it as lick-a-tree root beer due to the low sugar content, but I enjoy the taste.

Hot Or Not — 3D TV

Change Re:Active glasses? (419 comments)

Unless you can develop a backlight that can switch polarizations easily and quickly (or a filter over the TV that can switch back and forth), how would the TV produce alternating polarized images? It's easy at a movie theater, you just have two projectors, each with their own polarizer. It could be done with a projection type TV (such as with a polarized color wheel for DLPs), but I'm not sure how it would be accomplished with a direct-view LCD or plasma TV.

Hot Or Not — 3D TV

Change My brain/eyes are incompatible with 3D TV/movies (419 comments)

When watching 3D movies, I tend to go cross-eyed and get a headache very quickly. I think it's because everything I'm seeing is on the same focal plane, but my eyes attempt to adjust for parallax based on different apparent distances of objects. I had to walk out of Avatar 3D after about 10 minutes, I just could not watch it like that. Does anyone else experience this?

Microsoft Releases Prototype of Research OS "Barrelfish"

Change Re:"Green Arrow". (366 comments)

In California, home of the rolling stop, we also have many double right turn lanes at the end of freeway offramps, where the the two rightmost lanes are for right turns. Californians have come to behave (erroneously) as if a right on red is legal from either lane. Rather than educate the drivers, cities have begun installing NO RIGHT ON RED signage at these intersections.

Where is such a turn prohibited in the vehicle code?

21453(b): Except when a sign is in place prohibiting a turn, a driver, after stopping as required by subdivision (a), facing a steady circular red signal, may turn right, or turn left from a one-way street onto a one-way street. A driver making that turn shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to any vehicle that has approached or is approaching so closely as to constitute an immediate hazard to the driver, and shall continue to yield the right-of-way to that vehicle until the driver can proceed with reasonable safety.

22100(a)(3): Upon a highway having an additional lane or lanes marked for a right turn by appropriate signs or markings, the driver of a vehicle may turn right from any lane designated and marked for that turning movement.

You come to the light at either of the right-turn lanes, you stop, and if it is safe to do so you may make a right turn.

5 Powerline Networking Devices Reviewed

Change Re:Seriously? (153 comments)

Plastic raceway.
http://cableorganizer.com/surface-raceways/latching.html
I use something similar to run speaker wire to my rear speakers. I have it run up the side and across the top of a doorframe to the corner of the room, then it goes up to the ceiling, and along the ceiling/wall edge to the speakers. It blends in fairly well.

You can also pull up the edge of your carpeting and stuff cable under it (along the walls works well, but I wouldn't do that across a hallway or doorway), or remove your baseboards, cut a cable path into the drywall, run cable through it, and replace the baseboards.

Internet Killed the Satellite Radio Star

Change The Sirius-XM merger killed it for me (368 comments)

I had XM radio for several months, and liked it quite a bit. Then Sirius and XM started working on their merge, and XM ditched several channels in favor of Sirius programming. The channels I listened to on XM had real DJs, playing music that I liked about 95% of the time. Afterwards, all the channels I listened to were gone and had been replaced with automated playlist channels playing music I liked about 5% of the time. Whoever was building those playlists had nowhere near the ability to tie together a long stream of songs, it does take some skill and knowledge of the music to be able to make a cohesive playlist. I tried for about a month to like the new format, but I just couldn't get into it and cancelled my subscription. For me, it was Sirius's programming that killed XM.

Netflix changes its mind, will keep Profiles featu

Change Change writes  |  more than 5 years ago

Change (101897) writes "I too was disappointed at Netflix's decision to remove the Profiles feature, and let them know via email and telephone. I was surprised to find the following email in my inbox today: "You spoke, and we listened. We are keeping Profiles. Thank you for all the calls and emails telling us how important Profiles are. We are sorry for any inconvenience we may have caused. We hope the next time you hear from us we will delight, and not disappoint, you." I thought that it sounded too good to be true, and went to their blog to confirm, finding this entry. Netflix decided to listen to its customers, and keep a feature that many of us find essential for our use of their service. I am surprised, and very pleased."
