Circuits and PCBs – Solder stencil experiments and more

It was a pretty quiet for the circuits and PCBs night, but that didn’t stop anyone from getting into some hardware. Angus got working to try to cut a solder stencil on the laser cutter for his nixie tube driver PCB. First attempts were a little burnt, but slowly he refined it down to an almost usable stencil, a little more work needed to be done to allow for the smaller pads to be cut at a lower intensity since the heat stayed for a length of time in a small area, charring around those spots. Bevan worked in the back room on his UAV project, showing the 3d printed motor mounts and how he’s constructing the airframe; the brains of this aircraft is an ardupilot.
