This weekend, just designing a new type of lithography exposure process platform for hobbyists. Getting sub-micron 3-axis repeatability is an interesting problem, as one explicitly considers where to source economical mechanical precision.
Mostly just bored waiting for my Tungsten sample shipment to try in a new metal 3D printing process (at $90/in^3 you figure people would just air mail it, but nope cause it is a fire hazard.) Container rail transport work stoppage means I may get time to entertain low priority vanity projects.
Also working on a physics inertia puzzle so embarrassingly stupid... I refuse to post it lest it wastes 1 minute of someones time.
Kind of like this ear worm... these kind of problems are annoying... lol =3
