update: i now mounted an Axis 205 IP-camera and a linksys WiFi Router which both work on the 12V battery. the IP cam needed a voltage regulator (LM7805) in between the cam and the battery (for the 5V .5 A power supply).

Now I can watch the webcam feed on my iPod Touch and control it on my Android HTC Legend  xD

Can you post source code, please?


Thanks! :)

source code? for what? arduino? processing?

im not gonna put my *lifework* here out in the public hehe ;)

just what would you like te know, for example?

I was curious to know what kind of control system you were controlling the motors, whether it was PID or not.

for each motor, i use two relays to go back/forward, and a MOSFET to control speed using PWM. Each relay is controlled by a transistor, which is connected to an arduino port.

here's a picture:

You could always post it under "something else", and it is something else! Very cool idea!
