@davepl1968 Can you at least for the sake of respect download the datasheet and see how it works? I mean it in the least offensive way...

I need some help with this basic buck converter! Grok insists that I should tie Pin 5 of the LM2596-T to 5V for ON. The datasheet is labeled !ON. So I have tied it low. Grok is morally certain I'm wrong, but I have a "feeling" I've done it this way before. Can someone with actual hardware chops tell me?

@The_Kyle_Mann Eso te pasa por poner siempre el generador en el núcleo y que un torpedo de fotones lo sobrecargue y explote. Uno pensaría que después de la primera explosión Vader ahogó al contratista o algo...

Everyone said it was daft for me to build a giant battle station. But I built it all the same, just to show em. They blew it up. So i built a second one. And they blew it up. So i built a 3rd one, this time made out of an entire planet. That one... they also blew up. So for the fourth one... i built 1000 battle stations. They also blew them up.

@blind_via At a couple of ohms each of those fat tracks, no...not a good idea for power nets.

2 layer pcb, with only 1 layer of copper. signals should travel through the conductive resin just fine, probably not a good idea for power nets

@blind_via Usually specs are a bit unreal. Like '100 amps in 10us non repeatable pulse with the device fully submerged in oil @10°C and an infinite heatsink with an Rth<0.1 W/k'.... So when you have a real world application and meet current and timing requirements you have to do this...

Has 4 gates in parallel, so I figured it was trying to match a high current requirement. Learn the requirement was 100 amps, and it appears a single chip is rated for enough. So why parallel 4 gates I wonder? 🤔

Name the component?

@cgallaty Yes...'borrow'...

Steve Jobs: How can we borrow a standard, but lock others out from using our stuff? Apple Engineer: Hold my venti frappuccino...

@pablogarello_ Es el redmi.9A, no es un modelo tan malo

Mi vieja se compró un celular por 114 mil pesos. Lo mismo que sale una compra semanal de supermercado. ¿Se dan cuenta que este modelo no va a ningún lado? Es completamente irracional

@Rainmaker1973 51°C...third degree...? Dood...c'mon...

This video was taken in India, which is currently the hottest country in the world. Tap water has a temperature of 124°F or 51°C with no water heater. Exposure over 3 minutes could cause first degree burns.

@eevblog When we were little children we made mud pies...well, that's the topping.

@maxifirtman Y tampoco. Hay máquinas que hacen copias perfectas cuidando el libro. Try again. treventus.com/scanner/automa…

Anthropic primero pirateó libros en PDF y por eso terminó acordando pagar en un juicio colectivo. El siguiente paso fue comprar libros usados, escanearlos y destruirlos. El objetivo no es destruir todos los ejemplares del mundo como algunos derivan sino tener escaneado un ejemplar de cada libro del mundo. La destrucción es un tema de costos: la forma más fácil de escanear el libro es romperle el lomo y meter las páginas sueltas en un escaner. Luego se lo transforma en pasta de papel. La discusión es extraña. Los libreros a los que les compran los libros se quejan. Casi que consideran que no es un comprador calificado porque destruyen el libro.

@ProofofMaro Uh uh uh! You call Sammy Hagar and tell him he's back in the band!

@ProofofMaro You send them home with a note.

@i2cjak *Puaj...a PIC...urgh. *Look! A bunch of gates with a clock! *What's that....P...I...C...? And what would it be? A midterm high school tech project? * Back in 2010 I designed by hand a core using Tanner L-edit and MOSIS' AMIS05 process... It was neat and better than PIC...

microchip has released a NEW ARM Cortex-M0+ microcontroller in a DIP package? PIC32CM6408PL10028 Finally all of you DIP-cels can move to a modern chip architecture

@Cypher1984 Mismo orden que la pizza: sustrato, salsa, queso. Cualquier otro orden es una blasfemia, una imprecación que clama la venganza inmediata del todopoderoso, olas como montañas, ríos de lava y azufre, el león conviviendo con el cordero y el final de los días.

Definamos esto: la salsa de la milanesa napolitana, va debajo del queso o encima?

@ThePhysicsMemes You know, I have that question too. Why not use it where a lot of heat is needed? With all security measures, of course...

If nuclear waste will still be radioactive for thousands of years, why is it not usable? #Science

@utopianalien 'No se puede estar en misa y repicando', que tiene muchos tintes españoles. Pero está el argentinísimo (y un poco campestrísimo) '...vos querés la cancha, los 20 y la máquina de hacer chorizos...'

qué frase en español puede usarse para traducir "you cannot have the cake and eat it too"?

@SenhorZiborro Yo digo que es brillante...

A prisoner in Iowa made headlines with a highly unusual legal argument: that his life sentence had technically ended after he briefly died in the hospital and was resuscitated. Benjamin Schreiber, who was serving a life sentence without parole for murder, suffered severe septic shock in 2015. His heart stopped, and doctors had to revive him five times. After recovering, Schreiber filed an appeal claiming he had “served his life” because he had legally died, even if only temporarily. He argued that being brought back to life meant he was now living a new existence beyond his original sentence. The Iowa Court of Appeals rejected the claim, calling it “unpersuasive and without merit.” The judges ruled that a life sentence means imprisonment for the rest of one’s natural life, not until a temporary medical death. Schreiber remains in prison.

@highfreqhertz Everyone is potentially a couch warrior. As always, the line stands between them and the people who stands up and actually do something.

I find this hilarious when the vast majority of rockets use existing technology, because that’s how this whole “engineering” thing works. It’s no secret that Falcon 9 is a simple rocket, technologically speaking, it uses kerosene, has gas-generator engines, it’s really not too special during ascent. The fact that it lands the booster with pinpoint accuracy is what’s so special, and people will deflect and deflect to ignore this fact.
