EE treasure hunter again

[arjoca mihai]

I would say special thanks for those who mail me
the source code for 16f84a and the schematic changes,
I try now to “digest” it and I’ll be back soon with more news.
I also notice one more difference between circuit diagram and PCB.
Pins 8 and 9 of 4066 switch are inverted but I think that don’t care.
All the best
Arjoca

T-Hunter and Tracker PI, again

I must note that T-Hunter schematic was been taken for a basic in Andrey Schedrin's TRACKER-PI.
You can see some differencies in these, but it is not so principally. as AVR has comparator so it was great decision to use Atmel.
