#bigclive #video explaining those little electromagnet-powered “perpetual motion” desk toys, showing the circuit consisting of a single npn transistor and the electromagnet, which is actually sort of an autotransformer. A high-resistance winding feeds some current from the emitter into the base, and then a low-resistance winding runs from the base to ground, while the collector is held at 6V. As he explains it, the approaching magnetic target starts switching the transistor into conduction, and then the transistor turns itself the rest of the way on? But then at some point the current stops rising, so the magnetic field stops rising, so the current into the base stops, and the transistor turns off, and the falling current snaps it even more thoroughly off. He reports that it still works if you add a flyback diode across the low-resistance winding, which is what you would normally want to do, but they don’t bother; I assume that drives the emitter-base junction into backwards (zener or avalanche) conduction during turnoff, and I don’t know what effect that has on the voltage. One of them has a duodecahedron I don’t recognize at its center, consisting of quadrilaterals that aren’t rhombuses; maybe it’s a distorted rhombic dodecahedron. #electronics #hardware

#news “Top Oversight Dem launches probe into ABC’s Kimmel suspension” today. Reprinting a press release: “California Rep. Robert Garcia, the top Democrat on the House Oversight and Government Reform Committee, announced Thursday he is launching an investigation into ABC’s suspension of “Jimmy #Kimmel Live!” following the host’s remarks regarding the death of conservative activist Charlie Kirk.
His probe will review the Trump administration, ABC and TV station owner Sinclair amid what Garcia says are ongoing efforts to “censor opposition.”
“Every American has a duty to stand up for our First Amendment values. We will not be silent as our freedoms are threatened by corrupt schemes and threats. Anyone who is complicit will need to answer to us,” the lawmaker said in a statement.” This seems sort of like a ko threat in go: by threatening something defensible but even more damaging, #Trump can divert the opposition’s efforts from releasing the Epstein files. #USA #politics #human-rights #censorship

Holy shit, #Trump has gone too far right for the Drudge Report, which leads with a photo of Jimmy #Kimmel and the headlines “ABC MARTYR / NETWORK UNDER GOVT CONTROL / ‘VIEW’ CENSORED / TRUMP ORDERS REMAINING LATE NIGHT HOSTS REMOVED / THREATENS LICENSES”. #censorship #human-rights #politics #USA
