#dnesbastlim# rur23 No - dnes - začal jsem už v pátek, jakože nějaké krátké video (do minuty) o tom, co bastlím. Ale to máte: logo, 3D vizualizace, fotky a videa, titulky... Minutové video a je za tím MNOHO hodin. "Taková blbost a co to dalo práce! " youtu.be/LeqMHhdcO2k?fe…

Podpořte na @doniocz vznik knihy #MatematikaBitcoinu - Matematické principy bitcoinové revoluce a získejte tak do Vánoc beta verzi manuscriptu ve formátu pdf. V roce 2026 jsou v plánu rozsáhlé korektury, aby příští rok vyšla finální verze. Více na donio.cz/matematika-bit… dík
On October 18th, 1954 the first commercially available transistor radio went on sale. The TR-1 was produced by Texas Instruments. $51.10 in 1954 is roughly equivalent to $490 today!
This 4096-bit core memory powered the Soviet Saratov-2, a clone of the DEC PDP-8 computer. These 4096-bit planes, each containing a 64 x 64 grid of cores, could be stacked to form the total memory.
PUYA PY32F003L24D6TR 24 MHz ARM Cortex-M0+, 32K flash, 4K RAM $0.09 @ 6k Yes, you read that right. An ARM M0+ with actual flash for less than 10 cents. Featured in the "Software Defined 555 Timer" Includes SPI, I2C, UART, 4 timers, PWM, etc.
poslechněte si přednášku, co jsme za celé roky i s @petrkr v labu vytvářeli.
Jak bitcoinovou platbou rozsvítit lampičku? Jak pomocí kočky generovat entropii? 🐈 Nejen to se dozvíte v další přednášce projektu Konfa. Link na video najdete v komentáři🧵👇

Happy 45th Birthday PAC-MAN! Released in the USA on 30th October 1980 Here the creator Toru Iwatani shows his original drawings for the game
The Intel 4004 was made possible because of Bob Noyce's Rubylith process. This was all cut by hand. Pretty neat!
Hledáme do firmy někoho na výpomoc. Primárně pro základní on-site podporu uživatelů, dále pak pro evidenci techniky a přípravu podkladů pro poptávky běžného hw/sw. Cca poloviční úvazek, pracoviště v centru Prahy. Bližší info: dex zavináč procon tečka cz a RT pomůže😉
If you ever played Space Invaders you surely noticed that each time you killed an alien the game went faster. But, if you checked the source code from one of the arcade machines, you would find nothing related to this. That's because this mechanic is a hardware accident. The…
It’s the world’s first #CPU! Wow, seeing this historic chip first time with my own eyes is an unforgettable experience. Decapping went flawlessly, no bond wires damaged. And here it is X, the top metal layer of the 4004, Intel 1971, how cool is that!!!
It’s the world’s first #CPU! Almost 54 years ago, on November 15th 1971, #Intel launched the first commercial single-chip microprocessor. With the following tweets, let’s jointly explore the greatest milestone in #computing #history after the invention of the #transistor!
I like to doodle as I explain things. I always end up doodling something like this on paper every time someone asked me about how to start a project/build a game studio. So I thought sharing this as an infographic might be useful for aspiring indie gamedevs out there.
Should humanoids have tails? Current legged robots struggle with center of mass control and quick stabilization. Adding more DOF to legs gets complicated fast. Nature already solved this: Cheetahs, kangaroos, dinosaurs – they use tails for dynamic balance, sharp turns, and…
