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...)

If you're specifically doing it for interfacing with infared you might want to check out the linux infared project (which is well advanced at this stage). I believe that one of their daemons writes all incoming infared transients to a fifo which you could then read. http://www.lirc.org/

hi,
you also can missuse a joystick port for reading in analog data in low resolution. thats most likelz the cheapest way to do it.

If your voltage is between 0 and 5 V you could use the Doepfer Pocket Electronic. It's 80,- and reads 16 voltages. Gives them out as midi controller.

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
A medium-cheap solution is Christian Klippel's cvbox (http://mamalala.de/files/electronic.html). It's a scalable A/D converter solution with 11 up to 88 input channels with 8, 10 or 12bit resolution. Pd and jMax externals to read in the data are available...

If you're using GNU/Linux on a PC, try the joystick object from the ggee externals. Make sure the signals are adapted for the joystick port: http://www.epanorama.net/documents/joystick/pc_circuits.html#generalinput

IIR, the joystick object isn't in GGEE anymore. The external to use now is J. Sarlo's joystick for Linux and Windows, maybe OS-X, too, from http://crca.ucsd.edu/~jsarlo/pd/
I use this a lot, and it's not actually low-resolution, as someone else said here. It provides a range way above midi (~ +-32000), but with a playstation pad, that is a bit hard to control exactly. Otherwise it is a wonderful complement to my buttonless midi fader box.

Hi,
I made an overview of the possibilities at http://allserv.rug.ac.be/~jtaelman/articles/interfacing.html I'll try to maintain this document (unless it is redundant).

not yet done...
but if you are familiar with the stamp you could build your own:
www.interaccess.org/AID
currently reads and writes to the 8bit bus via ascii commands sent via serial.
(not yet used it in PD, only used with switches no real AtoD) Ben
