I finishing am a new board that is going to be shield compatible and use the ATmega32U4 with the AVR109 bootloader. I will post some info on it in a separate thread.

I would either use assembly services or get a stencil, some paste and go cooking them.

Eagle3D runs as EAGLE ULP script, which processes the board into a POV-Ray file which is then rendered. Each component is a POV-Ray macro; it usually takes some fine tuning to get it rendered properly, only a few boards get rendered properly on the first try. Here and here and here is some interesting info about it.

First things first, I have been experimenting with the Arduino for some time now, but I didn't post anything here. Anyway, for some reason I found making PCBs with EAGLE to be pretty addicting. So I made this. I liked the Sanguino for the unusual MCU, but there were a few factors I didn't like.

Based on work at www.sanguino.cc and www.arduino.cc

Improvements:
  • Uses ATmega644 in SMD package
  • Has USB using FT232RL, just like in Arduino Duemilanove and Diecimila
  • Shield compatible
  • Pins marked similarly to Arduino Uno
  • Can automatically select between USB power and DC jack
  • Uses micro USB to avoid shorting out any shields.
Overall, it is a more Arduino-ish modification of Sanguino and uses the same software.

Too bad I don't have a working prototype, but BatchPCB hasn't shipped it out yet. Also, if it's ever to be mass produced, I want the solder mask to be white with black silk screen.

This isn't the only thing I invented. More boards with more interesting MCU's are coming very soon.

Any ideas, suggestions? Tell me right here, right now.
