Thanks, Robert.

I was so impressed with this gadget I did some research, and found that this is based on an original design out in the public domain. The basic version has *very* simple hardware, Unfortunately, based on the *other* family of micros.

For anybody wanting to roll their own: http://translate.google.com/translat...Fpage_id%3D148

Hi Anand,
Well, you just sold one to me, I also just ordered an ESR tester a couple of days ago, had never really seen one before, seems it is for all practical purposes an A/C ohm meter, as it tests capacitors at 100kc. I will review it when the kit comes.
BTW, this tester you showed us is MUCH cheaper than the esr tester.

EDIT: 12/10/2014
This is the esr meter , I bought the kit:

I assembled it last night . . . Works Great !

Glad!

Further probing reveals that the original design was by a guy called Marcus. Later, his design was improved upon by Karl, and he's keeping on adding features to it (including ESR, I think). The Chinese stuff on Ebay is pretty much based on that.

I put together a basic, minimalistic version of the original for a pal (minus the auto-switch off circuitry and the LCD, the data displayed on the LCD is also given out on the UART, can be monitored on the PC).
