today I finished my Delta Pulse 3. It was tricky without an english (or german) manual. Turkish is not my motherlanguage.

I made any little changes. T16 (BC557) seems to be in wrong direction (180°) on the PCB.
I substitute with BS250. I have no 74VHC4051, I use an ordinary 4051 also a 4094.
The transistor IRF740 gets very hot, I spend a cooling plate. The discrimination mode is very poor. Perhaps I made an error. The sensitivity is good. I can detect a 1 Euro coin about 21 cm with "factory settings".

Jürgen
