Loading 3D model… large boards can take a moment.
We wanted to run a "lunch and learn" day at the company I used to work about soldering. I always liked Protopic's Day of the Geek Soldering Badge, but it only turns two LEDs on when you slide the battery, and I thought that my mates would need a bit more than a couple of LEDs to be able to say that they know how to solder, so I thought on modifying. I checked around but it seems the project is not open source, so I decided to blatantly copy get inspired by them.
So here I was, thinking how to improve it, if I should go nuts or keep it simple. Danny, what should I do? should I go simple?
As I wanted to do a bit more, I decided to add two features:
The schematic includes instructions on pretty much everything, so I recommend checking it. You can choose how challenging you want it to be, from "slide battery to get LEDs on" to "cap touch with breathe effect" and all the possibilities in between.
Turns out the badge is a bit overkill. It took me around 30 minutes to do one, and a colleague that has never soldered took something around 2-3h to finish it.
I was testing Cadlab when I was doing this project, you can view this project here.
I wanted to experiment with plated PCB borders. It gives it a very nice touch, but they are expensive, so you might want to make a cheaper version. There are two "footprints" for the soldermask "part", so you can choose to have the plated border or not. You might want to run the "Border" variant even without plated borders to get a nice copper outline, too. In any case, this board is yelling to be finished in ENIG, so please expend some money on that. Is not that expensive.
You can find the original SVG used for the art, as well as some SVGs I used to
Slightly improved version.
Slightly improved version.
First version of this board. It works 💃🎉🚀🦼! But not very well 💣🥦...
