hi,
i would also be interested in some scematics of that cheap A/D.
there is a cheap device by ELV approx 26 euros. go at www.elv.at (or whatever country the have the shop too) check out " RS 232 Messmodul "in the hard/software section at their online shop.
it has 6 analog in / 10 bit resolution but only 6 convertions / sec. and additional 8 digital I/O s.
another way for cheap but not very accurate A/D converting is to use the joystick port with the joystick object, and make some "analog joystick circuit" get some info at http://www.epanorama.net/documents/joystick/index.html
cheers

Is this design on-line?
i know about that because i have made many designs using that port, the last public one is a a/d input box, similar to that icube thing, but muuuch more ports and way cheaper.
