The cable that ships with it doesn’t have wires broken out for the power supply pins, but it appears there are 2 extra pins, 3.3v and 5v power sources.  I’ll have to see about adding 2 more pins to the connector to utilize them.  The factory cable has 8 logic wires, and 2 grounds, but the connector has lots of extra spots for wires, extra grounds and those power supply pins.

Anyway, you can’t beat the price.  Oh it’s also supported by Sigrok, an open source logic analyzer that is multi platform.

Me and my wife recently had our first child.  I’ve been trying to come up with some projects I can do for the kid.  Well, around this time of the year the fireflies go crazy around my house, so we came up with the idea to do led fireflies in a jar.  It should be something cool for him to stare at and is easy to build.

Schematics, C source code and hex file are available here on our wiki.  If you want to build one it should only take about an hour.

I’m planning on making a version 2 with some changes, stay tuned for that one.
