Table mode added to FBB. It auto-calculates minimum leg clearance so people can make coffee, end tables, and such. Not the sort of thing you'd want to 3D print, but you can get all the math right for noise, CADR etc in software and then build it out of wood. www.filterboxbuilder.com?d=AQLAjvsGoP...

For those of you into making DIY air purifiers using low-cost and recycled parts, we made a free P-Q tester for PC Fans using @phyphox.org on your phone and a 3D printed box. Learn about it here: github.com/opennukit/Nu... Test it here: filterboxbuilder.com/fangauge/ Great STEM-Ed project also😊
A 3D printed box the size of a loaf of bread with a sliding door on top. One end is open, so a 140mm PC fan can be bolted on with a gasket. There is a smartphone running the phyphox sensor application in the foreground.

Gonna try this excimer lamp from @nukit.bsky.social (thanks for donating one to my cause!) to kill off agrobacterium after co-culture as a means of antibiotic-free plant bioengineering. Agrobacterium resurgence is a huge pain and often we use frontline antibiotics to clear it away.

Nukit on X: "“Dogs are always going to come up short if you insist on defining them as a weird kind of cat.” So to begin with, reviewing the AirFanta Wear as a mask or mask replacement is completely unreasonable.

This is the first device of its type that can take both kinds of batteries, so it took some time to engineer with the limited resources at hand. The target sale date for the Torch 2 is the first half of January, 2026.

Batteries are removable (in case the airlines crack down, you can just run it off USB in flight and buy batteries when you land) and replaceable. It ships with LiFePO4 batteries due to the cobalt mining situation in Congo but if you flip the selector switch shown can take Li-ion.

Shown is how the bulb is easily changed. It lasts about 3000-4000 hours, and a spare is included. Torch 2 replaceable bulbs should be around $40 to $75 depending on mass production, which is just 1 or 2 cents an hour and probably less for power.

The Torch 2 injection molds are being made. This is the last 3D printed working model. There are just a few fiddly bits on the PCB we are finalizing. Smol lady hands so hard to tell scale- it's a little chunky at 188mm x 60mm x 60mm but still much smaller than the original Torch kit.

Yes, they should be significantly more effective based on the CFD models we have so far. Replaceable bulbs, batteries, can run off USB-PD, no time limit, better coverage, tripod mount on the bottom.

Pic of the new replaceable bulb for the Torch 2. No more throwing out the entire fixture each time the bulb dies (Yes, it's nuts, that's how basically all Far-UVC emitters work, yes, the industry likes it this way). It should really drive the price of Far-UVC through the floor.

This is Far-UVC. It's well tested on humans, but always good to jump at the opportunity to see if you can get it to do anything to other biology.

After a year+ of procrastinating, I've finally put together @nukit.bsky.social's Tempest air purifier, inspired by the fact I'm desperately trying to avoid my partner's COVID. 😭 Anyway, it's sleek as hell and runs so, so quiet. I particularly like the handles built into the top panel.

Our unusual customer in New York🫣 posted this to their Instagram and X (fortress_nyc). It seems they are pushing their Far-UVC and IAQ measures hard. Hopefully, customers will find it compelling, and other local businesses will do the same.

He's going to try Far-UVC and see if it makes mutants! (But seriously, the best way to test Far-UVC is to try and see if you can find a way to make it do bad things, not to try and prove it doesn't.)
