Hi all, does anyone know of any lo-fi or cheap solutions for getting a voltage reading from a line (basically read the status of an infrared detector) and into the serial object of PD, some sort of an A/D converter probably... I'm trying to see if there are any cheaper solutions than using a basic stamp (will be using mine for other things at the same time and am on a budget...)

for a cheap way, if you can buil a unit yourself, you may take a look at the ad-interface i made. http://mamalala.de/files/electronic.html
it hooks to the parport of your pc, has plenty of channels if you want, and either 8, 10 or 12 bit resolution. olaf matthes ported the driver to pd.
if you simply need something to detect a on/off state, you can use the parport directly. its pretty simply, just a few wires and resistors, i can help you on that if you want.
greets,
chris
