[Eduard] was kind enough to pass along this airport express psu repair how-to (Translated version). The old Airport had those pesky capacitor issues. Apparently the power supply in the little buggers can have issues. The solution? Add a pile of voltage regulators and some smoothing caps to get things powered back up. No word on how the new … Read the rest

DIY Canon lenses
December 30, 2006 By 6 Comments
Remember the cheap tilt-shift lens? [Rodolfo] let me know about his set of modded Canon lenses on Flickr. The FD 50mm prime is pretty cheap off ebay – he removed the FD mount and uses it sans rear-end. We’ve seen a nicer version of this before. His macro lens caught my eye – it’s a combination of … Read the rest
OpenTom – roll your own TomTom distro
December 29, 2006 By 16 Comments
TomTom already runs Linux. The OpenTom project has documented the TomTom hardware and software to allow custom software builds to run. The Wiki covers everything from build tools to hardware connections. So far, a mp3 player has been released using the build tools. Hmm, I might have to pick one up to develop on myself. Thanks to [kniVes788] for … Read the rest
The simpler USB2LCD
December 28, 2006 By 11 Comments
USB LCD interfaces aren’t new around here. [John] sent this latest one. It uses a single ATMega chip and a few cheap components to implement the whole thing. The venerable HD44780 compatible is the text LCD of choice.
I’m on vacation at the moment, but I’ll start putting up some Hack-A-Day design challenge entries pretty soon.… Read the rest
Atmega oscope

[Jason] sent in a couple tips, and this diy oscilloscope caught my eye. This design uses the A/D sampler on the ATmega to generate the signal for presentation on a regular CRT television. The sample limit is less than 16khz. Not terribly impressive, but not too shabby either.… Read the rest
Speedy2 R/C speed controller
December 26, 2006 By 7 Comments
Alrighty, this is a pretty straight forward one. [Jason] discovered our tips line – he sent in quite a bit of stuff. I scored a pair of $120+ RC cars for $25 each recently, and this would come in handy. In fact, the store drone that checked me out didn’t believe that I could build my own speed controllers cheaper … Read the rest
