Hattusa Pulse

[Hattusa]

it seems that no one wants to make a PI detector, and there is not even a suggestion, it is not important...
I will gradually design and share it myself.

This is the analog structure I tested above and want to work on.
a- what screen should i use?
b- Shall we add a button? How many buttons should we add?
c- how about the audio circuit?
d- Should it be android or PC connected? Should bluetooth be added?

I had this PCB made last year, I would like to remake its digital structure using its analog structure with your suggestions. of course for this site

The detector on this PCB does not have a screen, it is directly used with an android mobile phone via bluetooth.
