Here's my little prototype Arduino knockoff. I'm calling it the Pseuduino. Yeah, I know, the world doesn't need more Arduino knockoffs, but I don't care, I wanted one anyway! Besides, it was still cheaper than buying someone else's version (about 7-8 USD)(cheaper if futurlec would actually get parts delivered).
I don't have any LDO regulators, so this thing has two different inputs, one for 7-12V through a 7805 to power the micro, and another for 6V to power ten of the servo headers. The other two servo headers (D9 and D10) have 5V power from the reg (to run a PING))) for example). Six of the ten headers are on the analog pins. After I soldered it all up I realized it could be handy to have a jumper to select between 5 and 6V power to those pins, since any analog sensor plugged in there should be using the same 5V as AVCC and AREF (which is the same 5V as VCC)
While I'm still using the Arduino IDE to program it (because I drank too much in college to remember C++), I don't use the FTDI USB thing on this one. The 2x3 header at bottom-right is just the ICSP header, which the Arduino IDE can be set to use instead of USB. A future version may have a proper usb-serial connection, which would certainly be handy for debugging purposes.
The main point of this particular board is to be the brain of my current project, "Dan". Details on "Dan" should be coming in the next few days.
No, I'm not going to post a picture of the other side of this thing. It looks like red/silver/green christmas spaghetti.
