This is a controller i built a while back. I wasnt going to post it till i had a use for it but that might be a while. It uses a RBBB arduino, Radio shack project box, LCD, 5 momentary buttons, joystick, sliding potentiometer, wii nun chuck adapter, and a xbee.
I have a rf transmitter that i was going to use, but choose to use a xbee instead:
not too pretty but it will work :
Everything glued and soldered in:
Joy stick for controlling a robots movements. Buttons for sending commands. Wii nunchuck for fun :D. Sliding potentiometer for controlling things like speed. LCD for displaying menus and options. The xbee plugs directly into the FTDI programming port of the RBBB. One thing i kinda dont like is having the batteries inside, i have not changed the batteries yet but i think it will be a pain to do. Maybe i will put them on the out side one day.
I have not got the xbee to fully function correctly, you can help me out with that here: http://letsmakerobots.com/node/18666
