Atmega 644p

Re: ESR meter upgrades

good - because the replacement software wont fit a 324

this is actually built for a 1284 but it should work i think
it expects a 20Mhz crystal
changed config files are included for viewing

Re: ESR meter upgrades

i forgot to say,
you need to reprogram the 8 pin microcontroller that controls power, or replace it with a small circuit

Re: ESR meter upgrades

Thank's Stj have you found this better than the original.

Re: ESR meter upgrades

yes,
lots of new features.
but the biggest thing was the circuit for power.
the original 8pin microcontroller seemed to not go into sleep-mode sometimes and was draining the battery

Re: ESR meter upgrades

Which ESR meter would you reccomend for testing caps in vintage solid state audio gear? Do i need LCR so i can measure at different frequencys?

Re: ESR meter upgrades

vintage and solid-state arent 2 words you often hear together.
you mean 70's and 80's ?
