Controlling #LED strips with #Java on the @Raspberry_Pi is a "piece of cake" with the #Pixelblaze Output Expander and @jbangdev. More blogs and video later after my holidays, but already sharing a "sneak preview" 😉

Made a simple #breakout #PCB for the #UVC #led I found on Amazon, with ample room to add #filtering #circuitry and #current limiters later. The part is way too small to hand solder without experience so a cheap #PCBWay breakout is in order. Arriving Monday. Gotta love a quiet evening #tinkering 😀
3d printed black jig on a white surface that holds a glass rod, bookended by white luer lock fittings. A small blue pcb sits in a depression in the jig with a small UVC light sensor facing directly into the glass tube. A small gold UVC LED is placed nearby.
A line drawing of the UVC LED I found on amazon. Dimensions of footprint pads and casing are drawn. Below is a simple schematic showing the two LEDs (UVC and UVA) and their orientation with respect to the footprint pads.
A 3D render or the PCB breakout I designed. The footprint mentioned in the linedrawing is rendered near the top third of the PCB. At the bottom is a strip of pin headers in gold.
Back of 3d rendered pcb floating in a blue-gray void. White letters denote the pins. UVC/A + and - pins.
