I didn’t show it in the soldering section, but I also prepped a 20mm coin-cell battery as the power module. There’s a tiny on/off switch, but in practice I think it will be much easier just to remove the battery. Also, I didn’t solder the wires to the circuit boards because this is a temporary setup. I will be upgrading soon enough to a Leo Bodnar board that will get all the buttons on the F1 rim working, not just the paddle shifters!
With both circuit boards in place, the wiring gets a little cramped.
See the antenna? Placed the circuit board high enough on the mounting brace so that the antenna portion of the circuit board is above the metal, just to minimize possible interference issues with the bluetooth signal.
And finally, a little electrical tape to help keep things under control.
