Another update, it's been a while! I finished most of the control panel - it's installed and everything works. I didn't bother taking pictures of the assembly of the wires - honestly, I'm a bit fed up with those... Cut wire to length, strip wire ends, crimp the dupont connector pins, add the dupont housing, add the heatshrink wrap, strip the other end, pre-tin the wires, trim LED leads, solder resistor to LED, don't forget the heatshrink tube, solder led/resister assembly to wire, shrink the tube, install to control panel, hot glue led in panel, install the panel, connect the 57 wires to the circuit boards... whew. This is what it looks like underneath... The LED is on the CDU, if this doesn't light up, it's because there's a problem somewhere. So at this point, there are only two switches on the control panel that are not yet wired up. Those will go to the two turnouts on the layout that control the two reversing loops. Because of this, I want to automate those turnouts with an Arduino and some detectors. When the locomotive trips a detector, the Arduino will automatically switch the turnout to the appropriate track. The control panel switch will serve as a manual override. However, I'm not ready for that since those turnouts aren't ready on the layout yet - and I'm missing parts (need some relays and some IR detectors for the Arduino). Anyway, right now none of the remote turnouts on the layout are actually connected to the circuit boards, so there's that to do as well, but I'm not sure I have enough wire for the time being. That and I want to move on to do something else for now, I've had enough wiring for a bit Not sure what the next step is going to be, but It might involve finishing the main loop of the track. I'll update when I have something interesting to show! enjoy!
