As you can see, I've been busy.
Positively, it took me a long while to come up with a new kit to hawk off on you guys. I tried solar chargers, body-heat chargers, charger chargers, shake-powered chargers, USB powered fans, USB powered neck massagers, USB powered lockpick, and a breath freshening device that fits inside an Altoid tin. Those all sucked, and I had a really hard time getting them to work, so I thought I'd just start with something kinda easy.
Real easy: a 4" LCD screen for watching movies from your iPod video. Why not?
Initially, the hardest thing was getting the screen to stay in there. Finding a cheap LCD, wiring my own interface, programming an IC to interact with an iPod and pull the videos in raw feed over USB when they don't do that by default, and making it all charge with one 9 volt battery, that was all easy -- it's just a real bugger getting a screen to stick onto the metal tin lid. Seriously, that was about 2 weeks of R&D time (turned out tape works the best).
List of specs: the screen is 16:9 and is capable of displaying High Definition video. One 9v battery provides two and a half hours of playback for the screen, which is half an hour longer than the iPod itself can play video. You can use the extra 30 minutes of juice to fill your room with a calming blue tone, or a hip & with-it color test pattern, depending on how you wire it.
For the picture, I have an episode of LOST playing. It's ripped from the DVD in widescreen at high definition, compressed to 4:3 to fit onto the iPod screen, and the Altoids screen stretches it back out to 16:9, it looks pretty good I think.
Oddly enough, I spent two days trying to add PSP functionality too, for watching videos or gameplay from a PSP, then I realized that the PSP's screen is actually bigger than this screen.
Order now! Kits to build one of these are for sale right away. They run a mere $29.50. To put it together, you need to be able to cut, solder, strip, crimp, and bend wire. Also, you'll need to get a license from the FCC to own and operate the device, since it uses certain types of radio waves to operate. Instructions for that and a copy of the forms you need to mail in are included with the kit.
Let me tell you, you'll be the coolest kid on your schoolbus with one of these babies.
