Robot employee #113 looks set to complete his probation. If you stop and look at what he's doing at any given moment it appears bumbling and ineffective. But leave him to get on with his job and over time the quality of his work is impressive. He'll fit in just fine here. #automation #3dprinting

OK this kettle is several years old and in fact we're its second home. But it just broke today because on this otherwise all metal appliance, the lever you press down on every time to boil, is divided into two thin sections 2mm across. Can this be anything but intentional to reduce its lifetime?

Success! My lovely old Dell U3011 is back in action with new and uprated parts, after a wait for the boat to arrive from China, the fix went smoothly this evening - the real work was carefully desoldering the TOP266VG high-voltage AC/DC offline switcher chip, heatsink and a pair of TSOPs sharing it.

Ever had an R&D job go so flawlessly well, so quickly, that it simultaneously makes you happy and regret not doing it sooner? Repurposing these nasty early #RepRap knock-off #3dprinter heat blocks to make a 2.85mm equivalent of our 1.75mm #3dprinting filament joiner. Machinist's vice for the win.

Air conditioning is becoming necessary to keep staff safe and happy, but the UK the market being 'new', it's terrible we ever allowed single-hose portable units to be sold, they're an environmental crime! For the sake of #3dprinting an extra inlet hose adapter, we increased efficiency hugely (>30%).

I couldn't bring myself to walk away from repairing my Dell U3011 screen. Set a hard limit of half an hour to find a fix. Thanks to Google translation of subtitles on an excellent Brazilian dude's video I found the real culprit: this chip with the huge crater, under a complex heatsink. Part inbound!

I wont miss the fan though. FLSun thought that it was a good idea to put a CPAP fan on here for maximum cooling, and whilst it does blast a lot of air its also loud. you may notice the blue fan duct.

New favourite sentence: "The experiment focused on hexagonal boron nitride, or hBN, a material prepared by Prof. Hanan Herzig Sheinfux of Bar-Ilan University. In that material, light can turn into hyperbolic phonon-polaritons, hybrid wave packets sometimes described as “light-sound” waves."

Interesting thing on the @snapmaker.bsky.social U1 #3dprinter: The onboard firmware update gui specifies a series of separate firmware updates. First the main MCU, then individual #3dprinting tool heads. Not surprised, just nice to see the granularity, more interesting than bare % complete bar.

Well, after a full 24 hours, with a swap-out for fresh warm water after 12 hours, PVA supports did almost completely dissolve. The surface finish of those underside overhangs look exactly like top surface finish #3dprinting quality thanks to 0 spacing. Just a little residue in deep grooves.

Alex Gibson - edumaker @alex.edumaker.net · 13/01/2026
And the results are in: Pretty much as I and Dom predicted, 90% of the PVA supports are dissolved away in 12 overnight hours in initially warm then cold water. What remains is the dense interface layers in the deepest grooves. I've put in a fresh beaker of warm-hot tap water, testing passive only.
