/diy/ - Do It Yourself

What in gods name is this circuit? This is something my old electronics mentor would do

Just ram the output into a microcontroller analogue port and output the values over serial to your pc.
It takes like 12 lines of code, a single resistor and some jumper cables and will certainly take less time than whatever you're doing plus you get a nice graph on your pc instead of that 1990's ocilliscope
