Arduino on the TV
A couple of solutions are now floating around if you want to connect an arduino to a TV or monitor.
Nigel Batten’s Batsocks TellyMate shield is a low-cost solution that’s very easy to use since it listens to the arduino’s serial output, so you can use the standard Serial library to send VT52-compatible escape commands as if you were talking to a serial terminal. It’s very old-school (part of its charm, I think!), only B/W, 38×25 characters and uses the Code Page 437 character set found on the original IBM PC.
You can buy it direct from Batsocks in the UK, or from Sparkfun in the US. If you have the appropriate ATmega chip sitting around you can grab the firmware and burn it yourself. Keith’s also written up some great documentation on how he overcame the technical challenges behind generating the bitmap.
A more powerful add-on is the Propellurino, based on the Parallax Propeller processor which conveniently has colour VGA out and a PS/2 port for mouse or keyboard. The shield includes MIDI in, a microphone input and stereo audio out as well.
This shield’s available as a kit from e-robotix in Germany.

yeah, videobulb is great… I always assumed it was a PIC, since video code for that is widely available.
