DIY PCB
I wanted to perform an experiment and attempt to make my own "motherboard" of sorts for older locomotives, i.e. Bluebox geeps, SDs, etc.
It took a bit of time to try to find the best way to transfer the patterns drawn in MS word, but in the end it was vinyl t-shirt transfer paper that proved to be the best.
A 20-30 minute soak in ferric chloride etched the copper, then baking soda was used to stop the reaction followed by a rinse with running water.
Now that this proof of concept was a success, I'll update the board design with more output pads and provisions for resistor usage.
