Not owning an oscilloscope and needing to check out the hall-effect switching on my anemometer project, I'm looking at some freeware called Winscope for a possible solution. Obviously this is not a "real" oscilloscope. It uses the sound card on a PC to produce a visible waveform, but that should be good enough to set hall-effect proximity I would think.
I'm also hoping I can use it for calibration. With a borrowed anemometer I should be able to get a frequency for a given windspeed.
Reading thru the help section on the Winscope freeware I see a precaution that sound card inputs are typically not more than 2VAC. Since I'm planning on running an AH175 hall-effect on 12V it's a good thing I ran into that!
My sound card is an ADI 198x and I've googled myself silly looking for some info on something besides drivers .... but no joy. Probably not a good idea to put 12v in there anyway ....
So that's where I'm at. Any thoughts, help, advice, etc. are always welcome ...
