The arduino USB Power Shield has moved over to a relay design, to eliminate the voltage drop the transistors would have caused. Ports has dropped to two because a) no one needs to control four 5V devices, and b) the relays are latching and need two pins each.
The board isn’t done – I’ve ordered some of the relays to see exactly how they work with the Arduino and the diodes need to be figured out, but this is a good representation of what the final board should be like.

Also, there’s now room for a scrathpad that will be filled out with a 5V and GND bus for prototyping fun.

Totally scratching my head right now, I wish I was able to comprehend all that…or, for that matter, any. But hey, I’m just a film major.
Anyways, just dropping by to see what you’ve been up to.

The board looks fancy but all it does is take input from a microntroller and move a mechanical switch (relay) to turn on or off power connections to a USB port. 3 years of college and I’ve made a glorified light switch, haha.

Well, must be nice making glorified light switches for six figures a year – I think I’ll be lucky if I make five figures when I’m out of school, ok, four…
Film fest went really well, people seemed to really like the film. I’m still working on the Director’s Cut but yeah, the response has been so well received that I’m thinking about making it a feature length…we’ll see…
