Functionally, everything is now ready for the event trial run at the weekend...




I decided to use one power supply and a single channel relay board for now. The power is what I use for the 4-lane bullring oval, an adjustable 12-22V, 8 Amp switch-mode DC laptop supply. Also borrowed from the bullring is the legendary 'Cherry Bakewell' switch, which starts and pauses the races on the oval. When pushed and held, this now launches both lanes on the drag strip via the relay. The stuff in the picture has now been fitted in a rather inelegant, but functional enclosure. I'll keep the 2-Channel relay module for the Arduino / Drag Race Coordinator set-up.

I also had time to do a bit of tyre testing, which I'll post on the Proxy Drag Racing Anyone? thread.

Did you have this relay hooked up to an Arduino system, or DOS?
