Allright, summer holidays have passed, time to move on.

I started the first prototype board for the scanner, just to learn that I'm missing some parts.

So far, have a look at the board, I'v already ordered the missing parts and more images will follow.

Good news, everyone! I finished the prototype and it's - not working.
It seems like I made a mistake with the power suppy for lm324 which only receives single supply but needs dual supply.
All right, I'll run it through SPICE once more and we'll see what happens.
