Here's the schematic for the MOSFETs, hopefully all the wires connected correctly as I ordered some PCBs from JLCPCB for both the transistor and MOSFET versions. As an FYI, it was $2 for the first order of 5 (transistors), then $4 for the next 5 (MOSFETs) and $5.91 for shipping. Not too bad on the pricing. Due to the larger size than I have ever had before, OSHPark was $26.50 for 3 PCBs shipped. I can see clearly now what GRJ was talking about with the PCB size being a big factor on where to order your PCBs.
The plan is to assemble one of each PCB to make sure they work properly, then post all the Gerber and drawing files along with a materials list (Digikey part numbers included) for anyone that might want to make some of these for as a hobby project. With the Digikey part info you could most likely find the same items on ebay from Asia and possibly save some on the parts order.
Stan, I can't find my MTH signals either, I think I am missing a box of stuff somewhere? I probably put them in a 'safe' place somewhere... I'll keep looking, they should turn up one of these days? When found, I'll see about making the connections for them and a PCB to match and report back. And also a big Thank You for the assistance and the revised 4 wire design to make this work with some of the readily available traffic signals.
