Easy PCB projects that would be useful for arcade cabs?

I just bought a laser printer for etching pcbs and some copper clad is on its way to my place. Anyone have any ideas for some somewhat easy pcb projects that would be useful for arcade related things?

Are you doing the laser toner tranfer system to the bare PCB or you going to try photo-sensitive pcb etching ?

Toner transfer method using copper clad board and ferric chloride.
 

i'd buy one for my TUTANKHAM game...

seems like theres a lot of scuttlebutt ricocheting about
from many different quarters about TRACK AND FIELD stuff right now.

having the option to install one in a JAMMA cabinet with an ENDRIEN adapter...

theres problablay a more percentage game to sell to though.

Hmm that would actually be easy. I may try that.


Two layer boards with toner transfer is very tricky, accurate registration for the two layers is really tough. This is where photo process comes in really useful. Also Ferric Chloride is just horrible, messy and staining stuff for etching, it's much easier to use Sodium Persulphate. Although you do need to warm it to be most effective.

Have a look at the MG guide for prototyping. http://www.mgchemicals.com/downloads/appguide/appguide0804.pdf

When drilling you also have feed wire thru' the vias and solder top and bottom. But solid two layer boards are totally do-able. Just you wouldn't want to make a lot of them, it can be time consuming.

Do you know where I can get Sodium Persulphate, is it cheaper then ferric chloride? I'm having a hard time finding ferric chloride though I was told it could be found at an art store. If someone were to give me some means of telling where the converter would route wires(like where the 5v,12v,video, speaker,controls etc are on the connector) I would glad fully try to make an adapter for said game.

You need to get the pinouts for both Jamma and the board you are converting to Jamma and then jumper to appropriate signals to the appropriate place. The best place to locate these manuals is:

Hmm when I get my copper clad in the mail I'll have to try making a convertor so I can test my arkanoid...
 

dont forget that theres a parts side and a solder side of an adapter/PCB.

heres a mediocre photo of my BAGMAN adapter, parts side.

could be cooler though without all those different colored wires and extra unused traces.

Not sure how hard these would be but...

Pac-Man / Ms. Sink Bus Controller Board

Pac-Man / Ms. VRam Addresser Board

Yeah I know theres a parts/solder side. Getting the pinouts right would be the the hardest.

Also double sided PCB's with toner transfer isn't THAT hard, just a bit tricky.
