    It's approximately 3/8 x 5/16 inches, and was definitely a challenge to work with. The worst problem is when one of the components moves in the oven and I have to then move it by hand, and the resistors are so close together that they tend to get sucked onto neighboring pads. I have a new design that moves the resistors further apart and staggers them, if I ever decide to have a new batch made.

    Designing the board wasn't too difficult. It's basically done on the computer screen, and you just have to lay down the pads for the parts and then connect them. However the loco decoder board will be a lot more complex because of the number of wires. I'm already having trouble with the power board because a number of lines cross each other.

    I wouldn’t know where to start designing a board...!

    Ah... well that is a much more involved conversation, probably not suitable for this thread. :) But essentially it is similar to wiring something on a solderless breadboard in that you use a schematic to figure out what pins need to be connected together between components, and then you draw lines to connect those pins on the circuit board... except you can't cross your wires, they all have to go around each other because you're working on a flat surface now. The concept is easy to understand once you see it done, but trying to route all those wires can get rather tedious.
