Second episode in a series presenting a side project:
building a fairly simple tester to plot the current-versus-voltage
curve for a device (with a current range of six orders of magnitude).
The first episode covered designing the circuit.
In this one, we build and debug it on the breadboard.
00:16 Review the design
01:00 Building and adjusting
03:55 Testing an actual device
05:10 Trouble at nanoamp scale
06:03 Fixing the design
09:35 Another round of testing
11:02 Know when to quit!
11:31 Onward to the software!
Be sure to catch the next episode, where we automate the data capture.
