Recently I found on E-BAY several kinds of component testers labeled as GM328.
Having assembled several of these and using them, I am quite impressed with
the performance of such an inexpensive tool(a $10.00 kit). They will test for ESR,
identify transistors with pinouts, resistors, capacitors, diodes, inductors and more.
It also has a PWM output which could prove to be handy at times. I'm wondering if others
are using these testers and if there are more elaborate and better quality units available
for general component testing.
For the money, these testers are truly amazing!
I have no affiliation with the above but found this unit a fun assembly project as well as a very useful tool.
