I’ve been working on the external bits of the system now, which I’m a bit worried about being able to finish by mid-June… it’s coming along though. I think I’m going to try to fit everything into a project box I got a while back that’s maybe just big enough to fit:
- The 12v power supply (battery powered & rechargeable!) for the mixer, solenoids and motors (fingers crossed it’s up to the task)
- The arduino mega and the solenoid driver board
- The amplifier board(s) for the exciters
- Five (!) arcade buttons
- A mess of switches and knobs
- The spring tab terminals for the solenoids, motors, and speaker hookups
- Maaaybe a board and I/O with some opamps for basic buffered line level mixing…
I donno, we’ll see. If all I can fit are hookups and controls for the solenoids and 4 channel amp, that’s OK!
Nice to see them back in action again tho. I still haven’t sorted out my transistor board issue but I found a neat one for $10 on adafruit and it’s working great now that I’ve sorted out the inevitable bone-headed wiring mistake. :-)
Update: the voltage drop from the thinner wires is indeed noticeable! I’m actually out of hookup wire amazingly (only took 4 years! :-p) but some more is on the way to make all four as snappy as the first.
