continuity tester project....

[Hal]

for all of you that dont have one on your meter (like me)

helpful for testing for shorts and continuity when making PCB's, and troubleshooting....

I think i'l gunna whip one up pretty soon.

if all you want is continuity testing, buy one of these! Just don't test for continuity with the power switched on!

Better continuity testers limit the applied voltage to perhaps 50mv so it doesn't turn on a junction, even a germanium one, as well as indicating shorted only under some ohms value as this one does.

The capacitance meter from the same site is also very interesting: :mrgreen:
