Found what I thought was a good deal on jewBay.

Unit arrived defective and it was an old version, unlike the advertised current one. Goes back tomorrow, so far the return process has been painless but I am disappoint. Was going to use it tomorrow.

Unless you're doing things that require certain parts with certain ESR...for example RF circuits...knowing ESR isn't terribly useful. I generally work with older parts, and those are simply ready to be replaced due to age.

I've found that the best bang for your buck is an M-Tester. They're usually accurate enough for normal work, and most do ESR if the part is noteworthy enough to need it shown.

Yeah, the M-Tester rocks. Did you ever look into its history? It's kind of interesting.

The Peak ESR70 is way, way overpriced but from what I've seen, it has similar in-circuit capabilities as the Capacitor-Wizard. That last 'Spare Time Repair' Bose Wave video really brought me over the edge.

Lazy me wants the chance to zero in on a suspicious cap on a board before desoldering it. Story of my life. Always looking for the easy way out. :)

No, I've never looked into where those came from...always assumed it was someone's "Well crap I can do this better" or a senior project somewhere.

Nothing wrong with not wanting to unsolder every part on the board...

It was created by a German guy active on the mikrocontroller.net forum. First iteration was called the AVR transistor tester (German): https://www.mikrocontroller.net/articles/AVR-Transistortester It was then expanded and extended: https://www.mikrocontroller.net/articles/AVR_Transistortester (Notice URL difference dash vs understroke)

Here's a summary in English https://arnowelzel.de/en/m-tester
