Chumby digital picture frame teardown


At this year’s Consumer Electronics Show, Chumby unveiled their latest prototype. It’s a network connected digital picture frame that runs Flash widgets.

They let us borrow one of their open chassis evaluation kits to teardown and photograph. We’ve got more pictures, full specs, and the schematics below.

Passive MIDI foot switch


[Matt] was looking into some software that allows him to use his audio card as a means to control analog audio devices. After seeing how it worked, he got an idea to try to do the opposite.  He is sending a signal into his audio input, and piping it to a pice of MIDI software. The input he has chose is a foot switch. To create the signal, he simply needed to supply voltage while the switch was depressed. You can see above that he used a battery and a simple contact switch to send the signal. He then piped it to a virtual MIDI port using Maple Virtual MIDI Cable. Unfortunately, this isn’t suitable for knobs, but that may be next on his list.

Mario etching


[revolvingdork] etched his Eeepc with the entire level map of Super Mario Land for Game boy. He set the laser to 70% speed and 40% power to get it to turn out this way. This is a far safer way of expressing your self and playing with laser etching than tattooing yourself with the laser.
