Help - Tehkan trackball optical board pinout
cybernoid:
I had a nearer look at the transistor, an that is what is written on it:
C1815 Y 8C
I googled arround an came to this solution:
Here ist the pinout for the transistor:
Here is a basic circuit for transistors:
So, according several datasheets, the middle pin of my transistor is the collector.
Do you also think this is correct?
u_rebelscum:
Looks good, except the info on the transistor says it's 12V+ ??? I've been saying 5 V+ 'cause that's pretty standard; but it's possible the board needed 12V. Try 5V first though and see if it works.
cybernoid:
Sorry, i should remove the "Input/Switch" box from the example circuit, because is not the voltage for my transistor ::)

Hi all
I wired up the trackball analog the attached image and it works perfect ;D
I tried several mouses and had success with the Microsoft Mouse Port Compatible Mouse 2.1A 2-Button Mouse P/N: X03-61001 (newer Microsoft ones with wheel did not work for me).
Thanks for your help u_rebelscum :cheers:
