Hey all,

I'm very new to microcontrollers and I've been learning quite a bit by replicating others projects. My workbench is very sparse when it comes to test equipment though. I've come across http://pcsm1.u-strasbg.fr/liberlab/englishversion/ and was wondering if anyone could offer an opinion as to the soundness of the design. It's a few bucks in parts so I'll probably build in nonetheless. Would such a design provide accurate test data? Although I haven't abandoned ebay looking for a scope, this board has some of the features that I'm looking for. It looks like it is only able to handle positive voltage values. Could anyone point me in a direction to research expanding this capability?

I apologize if I missed some avrfreaks forum etiquette and have posted this in the wrong area. Thanks again for all of the interesting information you folks generously offer.

True, it's only for positive values, 0 to 5 volts. When you learn more about op amps this won't be a problem. It's also not as fast as a scope - the demo only managed about 100 samples per second.

If you prefer a solid board, then you might want to look at Olimex part no. AVR-P28.
