 I had to give a quick lecture on using the command line and came up with this to do live demos of using the command line. Embedded below.

     I've had a longstanding ambition to get a PCB manufactured but I've always put it off. Lately I had a need for a little adapter board to break out these 1.27mm spaced pins to 2.54mm pins that would fit into a breadboard. Feeling like it was a simple enough board I finally decided to fire up KiCad and give it a go.   <model-viewer alt="An interactive 3D render of a PCB with 2.54mm headers on one side to fit a breadboard and 1.27 inch headers on the other." src="/assets/blog/PCB/model/pcb.glb" ar camera-controls poster="/assets/blog/PCB/model/poster.webp" interaction-prompt="none" shadow-intensity="1" shadow-softness="1" exposure="0.5" camera-orbit="196.6deg 59.73deg 0.1m" field-of-view="30deg" auto-rotate> </model-viewer>

 It can be hard to find genuine everyday uses of 3D printing, but after a while you do find some! I made this little shelf to tidy up the wires to our devices in the bathroom. The wires are now hidden, coiled up, inside the shelf.
