Help - Tehkan trackball optical board pinout
<< < (2/2)
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:
