I don't normally do PCBs for people but I think it's beneficial here because it will show you how to design a PCB.
I don't know:
Attached is a PDF containing the copper mask and silk screen.
Make sure you print it at 100% scale, i.e. turn fit to page off, otherwise none of the components will fit.
I've added a back EMF diode across the relay because it was missing from the original schematic, it's not critical, the 1N4148 will do.
I don't know:
- What sort of phototransistor you're going to be using either, I've assumed two pin.
- What relays are available in Canada so I just used two pads for the coil, so unless you modify it or design your own, you'll have to mount the relay off the PCB.
- What size it needs to be or how you're going to mount it so I've just made it as small as possible and put holes for M3 screws.
