Prototype PCB arrived today I have just ordered the parts from Farnell. Not sure when I will get chance to build it, but I hope soon
I have been trying to work out how to fit a voltage selector switch to the PCB, but I think it is just not going to be possible I do not really like the idea of routing mains on the PCB when it is all low-voltage stuff there. Then the other way would be to simply solder the transformer wires direct to the voltage selector switch, but then not everyone would want the switch, and they would still be the problem of where to mount it and how. So I am thinking the voltage selector switch just not going to happen.
What I could simply do is not solder the primary transformer wires, and let the customer decide which voltage to wire it at. This way I would only have to keep stock of one power supply as it could be configured for either voltage, and this would also save me a lot of work also..
