555 Aquarium Feeding Timer
These photo correspond with the 555 Aquarium Feeding Timer project. Construction was accomplished with the use of DIY printed circuit boards. I used the toner transfer method to construct the PCB and a Dremel tool to drill the holes. Most of the components are through-hole type. The board was designed for a PCB mount relay, but I had a handful of icecube style units and used one of them instead.
