@STM32H757XI @madietlx The first part is correct, the "it has to withstand the reverse voltage" is incorrect, the LED will clamp the coil voltage. Try simulating it in spice. The LED will work in principle provided that the current through the coil is low.

[2nOrderEDO @2norderEDO]

@madietlx In some applications, such as camera shutter systems, it is desirable for a relay to turn off quickly. This can be achieved by adding a Zener diode in series with the usual flyback diode. This forces the current through the coil to decay faster, in proportion to the Zener voltage

[2nOrderEDO @2norderEDO]

@madietlx Many people misunderstand the voltage spike from a relay. The LED will clamp the coil voltage at Vf(I_coil) -> The direct polarization V depends on current. I_coil is the coil current at the time of switching. If I_coil >> I_LED_max then the LED will be killed.

@impossible_eng @seveibar Thank you for saving me the time to write it myself.

Os informo de que @Meta ha inhabilitado de forma definitiva e inapelable mi cuenta de de la red social Threads, supuestamente por incumplir sus reglas, sin darme más detalles.

De repente, la aplicación me pidió que demostrara que soy humano mediante un captcha, luego me pidió el teléfono para enviarme un código y luego una fotografía para demostrar que soy el propietario de la cuenta. Así lo hice.

Una hora más tarde, me apareció el mensaje que muestro. Pulsando sobre «Cómo hemos tomado esta decisión» me dicen que «Nuestra tecnología ha determinado que tu cuenta, o la actividad que hay en ella, no cumple nuestras reglas y, por ello, ha tomado medidas».

Mis únicas opciones, según META, son acudir a los tribunales o contactar con un organismo de resolución de litigios. Al pedir más información en esa opción, me dice que «algo salió mal».

Tenía más de 15.000 seguidores. Lamento el perjuicio que les pueda ocasionar.

¿Alguien sabe qué opciones tengo de recuperar mi cuenta?

Ahora que los rusos me leen quiero decirles que mi título de Arquitecto se la debo a la universidad pública y a las páginas rusas de torrents donde descargué todos los programas de diseño.

I received a false copyright claim on one of my videos and YouTube removed the video because of this.

It's a video about the Riemann Hypothesis. The claim comes from some person who submits a link to their paper about "The Continuity Engine: A Formally Verified Framework Prime Resonance Unification with Medical, Physical, Mathematical Evidence" with links to two unpublished papers that are completely unrelated to my video content. It's obviously some crackpot work, I receive dozens of those a day.

YouTube took the video down based on this false claim.

The only way they allow me to react to this requires me to submit my personal contact information to some random crank on the internet. Alternatively, I am supposed to hire a lawyer (!!) on my own costs, to track down some random guy from whom I then have to extract my up-front expenses.

I have complained to YouTube support about this multiple times. No success, the video is still down.

This procedure is completely unacceptable. It allows random people to try and blackmail me into responding to them. I have no time for this bullshit and no patience either.

Frankly the only sensible course of action forward that I see is to sue YouTube for facilitating fraudulent DCMA claims.

"¿Puedes indicarme a alguien que ponga precio al tiempo, que valore el día, que comprenda que se muere diariamente? En esto nos equivocamos, en que vemos la muerte en el futuro, cuando gran parte de ella ya ha pasado. Todo el tiempo que hemos vivido está detrás de nosotros. Procura, pues, Lucilio, hacer lo que me escribes que haces: abarca todas tus horas. Lograrás que necesites menos del mañana si te apoderas del hoy."

No le corresponde a los poderes públicos protegernos contra el odio, igual que tampoco tienen que protegernos contra el desamor o la envidia.

No se protege de los sentimientos o las emociones, sino de los ACTOS que nos hacen.

Y para eso, con relación a la actividad en redes sociales, YA existen: la protección de datos personales; los ilícitos civiles que dañan el honor, la intimidad y la propia imagen; y, entre otros, los delitos de injurias, calumnias, amenazas y acoso.

Always important to remember that a lot of these robots are "faking" the humanlike motions -- its a property of how they're trained not an inherent property of the hardware. They're actually capable of way weirder stuff and way faster motions.
