Hi All

I'm sure that the Peak unit (and others) discussed recently are very
nice, but could anyone point me to an open source ESR tester, or at
least the principles required to build one.

For one, I want to save money but at the same time, I really like to
make my own kit where practical.

In "PopTronics" (USA) July 2001, pages 25-28 there is a build it yourself
design that uses a few common parts and has full protection. It claims to
test in circuit from 1 uF on up.

You may find copies at larger libraries under "Popular Electronics",
"PopTronics" was a later name.
