Router I/O Bus Cable Problem
I am going to have to re-wire the router I/O Bus connection. I opened the router case to investigate giving the I/O Bus it’s own 5v line - the little 78L05 regulator is really only capable of supplying 1 usb device. I was running into power troubles hooking too many things to the I/O bus.
When I tried to open the case, I found that the wires to the Scart Plug had melted themselves into the plastic base of the router!

I thought ‘perhaps I had drawn too much power through the wires’, but the marks at the top of the picture are from the wires to the LEDs.
I guess the problem is a result of a chemical reaction between the soft plastic of the base and the rubbery style insulation used on the black wires from the ‘cheap’ scart splitter.
I notice that the scart to scart leads with coloured wires inside seem to be made with a different insulating material. I’ll have to re-wire, (using one of these) as when I pulled the wires from the base, several of them left a good portion of insulation behind.
