Raspberry Pi Gets 512MB Filling
This behavior by the phone makers has had perplexed me for some time now.
Can't they see how bad they're making the phones when they pile on all these crappy mods?
Atari 1200XL Stacked Up Against a Dell Inspiron
I had a 1200XL, and after updating the ROM, a 256K RAM upgrade, and the video output circuitry, it was every bit as good as the 800XL.
I actually took an XF551 drive modified to use a 3.5" floppy drive mech, and hacked the controller board and drive inside the 1200XL case. The floppy drive was accessible on the right side of the computer via a nice square slot I cut out of the case.
It was pretty darn cool at the time. SpartaDOS was very similar to MS-DOS in terms of a command oriented disk operating system, and I made the leap from my Atari to PC's pretty easily.
I can't believe someone came up with a SD reader hack for them. I'm amazed some people are still hacking them!
LED Lighting As Cheap As CFLs Invented
See this article on how dimmers work.
You'd need a circuit that detects the average power supplied, as opposed to looking at the voltage level of the rectified peak output. I haven't done EE in like 12 years, so maybe this is simple to do. *shrug*
It sounds like a cool project.
SCO Proposes Sale of Assets To Continue Litigation
Seriously, does this not seem like Darl McBride is so obsessed with going after "the great white whale" that it's all he can think about, to the exclusion of everything else?
Where and when does it all end?
What Micro-Controller Would You Use to Teach With?
For high school kids?
I think something like a Basic Stamp would be a better fit. You're not gonna have time to teach these kids Assembly Language or C programming AND still have time left over so that they can do something useful with it. I think you'd want to them over the hurdle of learning to program as quickly as possible so that they can move onto the fun stuff: making robots that can move, make decisions, sense their environment, etc.
I think learning BASIC would be much easier. It's what we learned in 7th & 8th grade.
We had 68HC11 Heathkit trainers in an advanced digital electronics class taught at the High School level. It took us a long time to learn to do even trivial things in assembly on those things, and we met for 10 hours per week. (Two 5 hour days).
