This is my 3rd project. A smart NiMh (and NiCd) battery charger.

A smart NiMh (and NiCd) battery charger. It use -DeltaV to detect end of charge. More details: http://arduinoelettronica.wordpress.com/2012/04/20/caricabatterie-intelligente-nimh-con-attiny85-e-arduino-smart-nimh-battery-charger/

Hi There. Thanks for the project. Apologies for posting so late (and in English !). Not sure if anyone is still following. I have built this, with one of the Digispark (ATTINY85 based) boards. The problem I have, is that - after the code loads, A1 pulls high - pulled up to 5V by the ATTINY itself, so it doesn't monitor battery voltage. If I load a different program (like the "start" program), the analogue input does not pull high, so it seems to be responding to something in the code, but I can not find anything in the code, which should cause the pin to set high. I'm new to these processors, and only bought the digispark boards to play, but any thoughts will be gratefully received !!
