RE: HP 45 High Precision Timer
Version 2 is ready to build and material for second batch is here.
Precision is really good. So far I had no unit with a derivation of more than 1 second within 72 h :-). Again 10 to 20 times better than version 1. Additional current load is up to 10 mA, so I will still generate version 1 at request with only < 1mA typical additional current load. Revised tutorial is attached. Feel free to contact me in case of any questions or when you decide to give curcuit a try. |
