I decided to make a proper board for stimulator too as I got tired of looking the wire mess.

UV-mask printed on to the laser transparency film. Second pic shows the UV-sensitive pcb template with the protective plastic still on.
I used a normal worksite halogen to develop the mask pattern on to the board.
Developed mask pattern on the board. Next step is to get rid of the protective laquer from everywhere else but the masked part. For that the board is dipped on to the sodium hydroxide (NaOh) solution.
After this the board is dipped on to the sodium persulfate (Na2S2O8) solution. Sodium persulfate etches the copper from the areas which are not protected by the protective laquer and the final result is an almost ready pcb. Solution works best with heated water so I used the surroundig hot water in the sink as a heat buffer for the solution in the container.
After etching we need to drill the holes for components and wipe off the remaining protective laquer with etahanol spirit. Now the board is ready for soldering.
Board came out pretty nice even though I did etched it quite quickly. Couple small faults can be seen but those were easily fixed with some copper wire and solder.
MegaSquirt is quite ready. The board version is V2.2. Only things missing are the FETs and LEDs for the board but I'll solder the FETs when I'll install the board in it's casing. The casing will work as a heatsink for the FETs.
Stimulator is the board at the most right.
What's in the YES-bag? Well it contains some proper industrial connector components which I picked up today as I don't like the unprotected D-SUB connectors in exposed enviroinment.
These have to be some of the most expensive connector pins I've ever bought. 1 euro a piece, gold plated.
So that's what has happened. Next step is going to be the wire harness.
I'm also going to be doing some welding in the inner wheel wells at the front. Aukki is probably going to provide me with some healthier parts.

I also bought a Hella-grille but it doesn't fit yet as the aux-lights interfere with the intercooler so I'll have to adjust the intercooler position a bit.
