After just one prototype, [Elia] has finished his super awesome Binary Wrist Watch.
He designed the PCB in KiCad, using a template for the PIC he found in a standard library — unfortunately it turns out the SSOP-20 PIC footprint in this library was actually a TSSOP-20. Confusingly enough, there was also a TSSOP-20 footprint in the library. Luckily it’s just a few millimeters off so [Elia] was able to just bend the pins in a bit before reflow soldering it in place.
The trickiest part of the project was actually making the wristband. He tried several different styles before settling on a paracord braid design he found on Instructables.
We especially like his quote at the end of the project:
Although not having worn the watch in the presence of normal humans, I can already guarantee that now everyone will be able to easily identify me as a nerd.
Acceptance is the first step in realizing you have an addiction, right?
