    La mia istanza Peertube, @viaggiatore_tv, continua ad arricchirsi! 💪🏻:peertube:Sto caricando quanti più video possibili, in modo da potervi offrire un canale riccon di guide e vlog.💚Se vi piace quello che mostro, condividete il verbo rilamcoando il toot. Qui mi vedete alle prese con l'esplorazione dell'Andalusia, un anno fa. Chi l'ha trovata bellissima, come me? https://video.simoneviaggiatore.com/w/tBUZ4zXeTesoA14F6poDxa#Peertube #mastotv #Andalusia #Costadelsol #viaggio #viaggiare #travelvlog #travelvlogger @Viaggi

    Io ar Bord of Pis de Trunp ce annavo pure volentieri. Figurate! Ciavevo pure già un'Armani nuovo 🤩 Solo che cé da pagà un bijetto de 1 mijardo e potevo solo più cancellà la sanità in LonbardiaEppoi ciò pure come l'inpressione che Trunp ce sta a cojonà pe spillà sordi.

    Self-Powered Top Spins for HoursThe meaning of Inception’s ending famously revolves around a top which spins forever in dreams, but in real life comes to a stop like any other top. Any other top, that is, except for [Aaed Musa]’s self-spinning top, which can continuously spin for about two hours before coming to a stop.The one constraint was that every functional component had to be contained within the top’s shell, and [Aaed]’s first approach was to build a reaction wheel into the top. When a motor accelerates a weighted wheel, conservation of angular momentum applies an equal and opposite torque to the motor. The problem is that motors eventually reach a top speed and stop accelerating, which puts an end to the torque. This is known as saturation, and the only way to desaturate a reaction wheel is to slow it down, which counteracts the originally generated torque. [Aaed] originally planned to mount the motor in a one-way bearing, which would let it bleed off speed without producing torque against the rest of the top, but it was rather choppy in practice.The solution occurred to [Aaed] while watching the aforementioned final scene, when it occurred to him that the wobbling of a top could actually generate rotation. A prototype proved that an off-center weight rotating at a constant speed did successfully spin the top by rotating the center of mass, and after that, it was a matter of incremental testing and improvement. A higher moment of inertia worked better, as did a lower center of gravity and a tip made from a hard, low-friction silicon nitride ball bearing. He made housings out of both 3D-printed plastic and CNC-milled aluminium, which each contained a tiny brushless motor, an electric speed controller, a microcontroller, and a small rechargeable lithium battery.If you allow for external power, you can make the top itself the rotor of a motor, and drive it from a base. Alternatively, if you levitate your top in a vacuum, it could spin for longer than recorded history.youtube.com/embed/Wp5NodfvvF4?…hackaday.com/2026/01/20/self-p…

    @nina_kali_nina as I would have injured myself if I kept going. It's a lot of fun. I put on drum and bass music to groove along to it while I draw, I set my cintiq up like I'm standing at an easel, and I count it as my daily physical exercise. I call it "drawing and bass".
