The Five Dollar Bubblegram Base

Some of my kids got some little Pokemon bubblegram balls at a con this weekend, but the vendors didn&#39;t have any bases for them. Well, I&#39;ve got a soldering iron and a box full of bits, so I made some! Features include a hidden capacitive touch sensor, WLED functionality, and only 12 total solder points! While running at full power with an RGBNW SK6812 pixel I recorded no greater than 0.5W (0.1A @ 5V) consumption, so any old phone charger should do to run this. I&#39;ve got a myriad of sizes available, supporting sphere diameters from 40-100mm in 10mm steps (and also 2-4&#34; in ½&#34; steps). Measure your sphere and pick the closest size. This project uses a couple of things:a D1 Mini v3 (<$2)a TTP223 touch sensor (<$1)an SK6812 pixel ($0.15)You could also use a WS2812B pixel, I just like having a white LEDtwo M2.3x5 screws (<$0.01)Two pieces 3-4&#34; length three pin wire (~$0.08)about $0.90 worth of PLA (any colors you want, but you will need clear/natural!)soldering suppliesa
