Chutney jar PCB etch
I had two circuit boards nagging me to be etched this morning. Without a photo developing tray, it seemed some modifications in technique were in order.

A little bit of cleaning, and it was ready for business.

The tea water was still hot on the stove, so it was ready to provide some double boiler action. I poured some hot water into a steel pan, put the ferric chloride into the jar and dropped in the first board.
