flow of the carbon ink coating tapered off while printing onto thin foil for this supercapacitor prototype looked like a work of art!

get your tickets now, almost sold out!

i guess one way to reduce vibrations between the vacuum pump and the probe station is to pass the vacuum line thru a 12-liter pail of hardened cement!

xenon lamp for photonic sintering with #2 gauge wire and three capacitor banks? yes please!

the ruler markings might need to be deeper, then perhaps stained for greater contrast? also forgot to toot the best part: the new text tool in sketcher workbench! #FreeCAD

this vacuum pump runs 24/7 and began leaking oil into its drip tray. luckily it was just the drain plug o-ring which had compressed and nolonger sealed properly!

was lucky to receive a commodore 64 and a few dozen floppies with software for free, but the owner said they nolonger had "the keyboard".

rescued this nema-17 stepper from the e-waste bin, even has a slim planetary gear, but the driver pcb might be toast. should have enough torque for a butter robot?

the problem is always dns!

luckily no back wash today!

the rack-mounted embedded system controlling the photonic sintering tool went offline, no power at all, pulled out the atx power supply unit and the high voltage capacitor was showing signs of failure. removed it and no longer holds a charge. also weird that when shaken i can hear the contents thump around inside. toast!

this little nanowire was found while running the optical profilometer calibration routines using a silicon carbide flatness standard. there's always some dust around, but this bit needed a closer look. the laser had some trouble maybe because the nanowire is transparent or highly reflective. it was around 100um long and 3nm diameter.

@thure@hci.social an academic paper on saffman-taylor instability is quite a dense read in fluid dynamics! i think i will keep "saffman-taylor instability" for my colleagues and "viscous fingering" for my friends.

@davbucci@mastodon.sdf.org having dual gooseneck led lighting is also fun compared to a ringlight, adjust the angle lower for less glare and better contrast.

checking the check valves

@freecad@social.freecad.org @concretedog@mastodon.social thanks a lot! if you are asking if the sketch is fully constrained... 'tisn't ¯\_(ツ)_/¯
