Would work nice, IF there is a universally accepted sound card to modify and some existing software that is close. The problem many would have with the sound card solution is not being too happy about trying to modify their laptops (or PCs), each with it's own type of sound card. I want this to be something that others can reproduce. ************** >From Poul-Henning Kamp >>PC data logging capability on a single channel >>in the 100 to 1000 samples per second range. >Your PC's soundcard ? 16 bits, 40-some ksps, dual channel ? ********************** >>I'm looking for a low cost and simple solution to replace an old 12 bit >>DataQ ADC in my "nut" project. >>What I'll like to find is a 16 bit bipolar ADC system or a four and half >>digit DVM / multimeter with PC data logging capability on a single channel >>in the 100 to 1000 samples per second range. >>It would be nice if it was something that does not take a ton of >>programming >>time and effort to get working and is readily available and cheap. >>Software that allows flexible real time graphing display and simple data >>logging on a PC is important. >>Cost and overall time and effort to implement, when figuring about ten >>units, being important considerations. >> >>WarrenS

You can easily do with commercial DMM [ e.g. HP 34401a] in the 4.5+ digit range, but what's the working budget?
