Old Acquaintance

This is a small one-off electronics box I put together quickly many years ago as a favour to a voluntary organisation. They have been using it regularly now for eight years. It came back to me to fix a minor fault so I took some photographs for future reference.

I re-used a PCB from another project to give me a Microchip PIC microprocessor and some other interface circuitry. That is why most of the components on the PCB are not fitted.
