my half #i3bear half Frankenstein is in the works. upgrading from a BQ hephestos, learned that isn't quite a clone of the prusa so a lot of fiddling. Can't wait for the electronics and firmware challenge. #3printing #3dprinter

This is my hot water humidifier version b. It works better than the first attempt in that it does not get waterlogged then sink, due to the use of Styrofoam (vs packing foam in the first attempt) for the flotation function. There is also thin fiberglass top and bottom to avoid glue that did not work in hot water.

Fiberglass sheet is inexpensive, strong, and water-resistant. Working with it can be a pain, though, because fiberglass tends to quickly dull saw blades and drill bits. I have found that Black & Decker Very Thin Cutoff Disks work really well for cutting large holes in thin (.03") fiberglass sheet. That is the first photo.

For drilling holes, a 600-grit diamond attachment on the Dremel tool works as fast as a drill bit might. That is the second photo.

finally installed the oleds in the #uBraids ! still having problems with the #atmega328p that I bought from #mouser. after reflowing everything, the one with the metal blank front panel still behaves oddly, weird glitches and too long time to refresh once I turn the encoder. the left one didn't let me flash at all since there was always a signature failure. after desoldering an atmega from an #arduino mini pro and replacing it into the uBraids everything worked!

I needed to humidify the space where I grow mushrooms. This is a low-budget, fuss-free humidifier. Unlike commercial humidifiers, it does not require purified water. It works by heating water relative to the environment. Power can be controlled by plugging the cord into a variac or other transformer.

The plywood circle did not have sufficient buoyancy, so I glued some foam on top. The slot in the stainless tube accommodates the appendage on the cup heater to make it stay put.

my first smd project is almost finished. only the oleds are missing in these two #uBraids clones of #mutableinstruments

This is my slow-speed drill press. it works well for drilling large holes in soft materials and for making gaskets. Directions for making such abound on the 'net, but I just ordered belts and sheaves that I thought would work from McMaster-Carr. If I were to do this over again, I would start with a heftier drill press, and I would use timing belts/sheaves instead of v-belts. Timing belts don't need as much tension to avoid slippage.
