10/30/2025 9 AM - introduction and planning

I have a lot of spare components from my projects in Highway and I wanna build something for Blueprint but I have no time for larger bc school

• this led me to thinking of many smaller projects that I can finish up when I have free time between classes (like now in ap stats), mainly comprising of stuff that I already have on hand
• I had a ton of SK6812s from a Highway project left over, which also led to me thinking of a way to add RGB lights to a project.

After some time, I came up with a light up ID badge holder

the name Polychrome is a balatro reference btw :3

I plan on having a heavy futuristic cyberpunk/futuristic vibe to the project, mainly drawing inspo from the Undercity PCB badges and some of my other projects (wink wink).
I also plan on using parts that I have on hand. As stated earlier, I already have a bunch of SK6812s for RGB, but I'm also scrapping some parts of my Sprig for the microcontroller ann buttons and a coin battery holder from Solder.

• I read online that a Raspberry Pi Pico can be powered with 3V, as well as SK6812 LEDS (to an extent), so hopefully this should work out

Right after my previous post I made the schematic

The circuit is very simple honestly

• The entire PCB is powered with a 3V coin battery, along with a Raspberry Pi Pico W (the one that came with my sprig) and a string of 10 SK6812s spaced around the id badge like this

• There are also two buttons, one programmed to shut off the LEDs and the other to switch modes

I also plan on testing this set up with a coin battery holder and led soldered to some wires at home

• If it doesn't work, I'll maybe try to add a converter to step up the voltage to 5v
