#video of Iran’s #Shahed 136 kamikaze drone servomotor. It uses an #STM32 with six power MOSFETs to control a brushless motor and read from an encoder; these motors sell for €20 in Ukraine. There’s a silicone conformal coating to protect the board. It uses a conventional 600μs–2.4ms PWM control signal. Interesting reverse-polarity protection circuit on the ground rail. Detailed schematic analysis, awesome. #electronics #hardware #microcontrollers #flying #weaponry #Le-labo-de-Michel

#bootstrapping H₂SO₄, which is apparently illegal in the #EU, but starting from the dilute stuff. #materials #video #politics #tutorial
another #video on #bootstrapping H₂SO₄ with oxalate and blue vitriol. #materials #scouting Deleted “for violating YouTube’s Community Guidelines”. #censorship
#NurdRage #video on #bootstrapping H₂SO₄ by blowing SO₂ onto a CuCl₂ solution, which oxidizes it the same way it oxidizes PCB copper, precipitating CuCl and also producing HCl as a waste product. Then you can reoxidize the CuCl with air before switching back to SO₂. He also mentions he made a previous video using H₂O₂ to do the oxidation. #materials #scouting
The Sun (garbage #UK tabloid) claims NATO tank #weaponry is too heavy for #Ukraine’s bridges or indeed those in most of Eastern Europe, which have a 60-tonne limit, and with active protection systems too heavy for even the ground. Lots of talking head footage and even repeating stock footage, so kind of a trash #video
as of a month ago, in #Ukraine, Russia had had 1800 tanks destroyed, 530 captured, and 270 abandoned. They’re starting to deploy T-55s and T-54s and US$4.5M T-90Ms (about the same cost as an M1 Abrams tank), but not T-14s. Another annoying #weaponry #video made of talking heads and stock footage. Russia’s new budget spends 6% of GDP on the military
#video on #Ukraine’s naval drone #weaponry, including the Marichka, a torpedo with a range of 1000 km and the ability to go dormant. Gets to the Sergey Kotov at about 15'30" and then the Tsezar Kunikov and the corvette Ivanovets, which apparently they also sank. The time-wasting talking head describes it as a “garage industry” — it’s decentralized to prevent Russian targeting of the production facilities. And apparently there’s an “Unmanned Systems Force” as a new branch of the Ukrainian armed forces.

#video on unsuccessfully attempting to oxidize SO₂ #materials with #electrolysis instead of catalysts or H₂O₂, using a platinum anode and a copper cathode. His electrolyte is dilute H₂SO₄. The hydrogen and oxygen being generated in a closed flask seems like a baad idea to me. His electrolyte turns orange, maybe because of reducing back to sulfur on the cathode. Oops, he got backflow from suckback and lost all his product. In a second run he got copper sulfide on his cathode and sulfur in the solution, which fortunately defecated. In two hours he did get the H₂SO₄ concentration up from 4% to 4.2% in his 100mℓ batch. Then he did a control test without the electrolysis and it went up to 6%.
#video on a manganese-dioxide/zinc 2.5-volt dual-electrolyte battery with KOH on the zinc separated from H₂SO₄ on the manganese dioxide by a chip of terra cotta clay. Actually it isn’t real terra cotta; it’s some kind of air-hardening modeling compound (“Das”, from Italy’s Fila Group). But apparently it’s porous. He gets 14–15mA out of his postage-stamp-sized battery with a chunk of graphite as the cathode current collector, despite the membrane being almost 2mm thick.

#video reducing boria powder to metallic boron with magnesium powder, igniting the mix with a butane hand torch after magnesium ribbon failed. Seems to be Polish. I feel like he didn’t do a good enough job of neutralizing the magnesia and probably had a bunch in his final product. That still doesn’t quite explain the 316% yield. #materials #bootstrapping

#video footage of a captured turtle tank in #Ukraine which had no ammunition and no explosives in its reactive armor. Then footage from a trench battle.
#video footage from the fascist Azov Brigade of trench warfare in the defoliated pine forest Serebryansky Pine Forest in #Ukraine. Evacuation of wounded soldier (left leg and pneumothorax) on a stretcher to an IFV. A puzzling thing is that there don’t seem to be any anti-personnel mines, though plenty of anti-tank mines.

#scouting #camping stoves: after trying canister butane stoves, white gas stoves, etc., the one he likes best is two chunks of unglazed porous pizza-stone-like ceramic soaked in alcohol. Basically a rock. #video
#electronics #hardware: some of those electrolytic capacitors without the safety-pressure-relief cuts aren’t actually electrolytic, they’re conductive polymer. Others are, though, they just use a conductive-polymer cathode and have more subtle pressure-relief cuts. They still degrade over time, though, because the polymer oxidizes and breaks down.
