Speech recognition on a microcontroller usually means a short list of fixed commands. Boumedine Billal has gone much further: his open-source project runs a full speech-to-text model live on an ESP32-P4, a chip that costs about $5. You talk into the board's microphone and any English sentence appears on its screen as you speak, with no Wi-Fi, no cloud and no neural accelerator. On the standard…
Most 3D-printed RC planes are slow foam-and-PLA cruisers. King Chaser is not. The Mach Initiative, a small team presented on camera by Josh Martin and Dan Sykes, has flown its 1-metre, 3D-printed jet for the first time, and it reached 273 mph (about 440 km/h) on a short private airfield. The team's goal is the Guinness World Record for the fastest jet-powered model aircraft, which currently…
Daniel Zellhuber's father lives in the Bavarian mountains, loves watching planes cross the sky, and does not use the internet. So instead of showing him a flight-tracking app, Daniel built him a small flight tracker in a picture frame. Whenever an airliner passes overhead, the colour e-paper screen shows the airline with its logo, flight number, route, aircraft type, speed and altitude. There…
An Arduino Uno has 2 KB of RAM, 32 KB of flash and a 16 MHz 8-bit ATmega328P. That is less memory than the 1982 ZX Spectrum had, and nowhere near enough to hold a frame of video. Even so, Smashcat has built a game engine that runs full arcade-style games on it at a locked 50 frames per second, straight to a TV over composite video made with just two resistors. It now runs four games: Manic…
Touchscreens are on phones, watches, fridges and car dashboards, but never on clothes, because a display has to bend, breathe and survive a washing machine. Researchers at the National University of Singapore say they have now cracked it. A team led by Assistant Professor Tural Khudiyev at the NUS College of Design and Engineering has built a fibre that is both a line of pixels and a touch…
The analog TV signals that old tube sets need stopped being broadcast almost 20 years ago, so when BorisDigital bought a 1995 Sony Watchman pocket CRT TV for 15 dollars at a thrift store, it had nothing to watch. A cheap analog TV transmitter board fixed that. Then he kept going. The result is a full 1990s-style TV station in a 10-inch home lab rack, built from six Raspberry Pis, two Raspberry…
The Nintendo Entertainment System was never meant to be a computer. It has a 6502-based CPU, 2 KB of RAM and two controller ports. Yet Throaty Mumbo has turned his NES into something that looks and behaves a lot like a 1990s desktop PC: a Windows-style desktop with a start menu, files and a trash bin, a USB keyboard and mouse, a MIDI keyboard, CD and DVD playback, and a web browser that can…
Bourns today announced the CSI2F-6918, CSI2F-7036, CSI2F-8518 and CSI2F-8536 Series Current Sense Resistor Modules. These module-style current sense resistors provide ultra-low resistance values from 25 to 200 µΩ, an integrated 10 kΩ NTC thermistor, continuous power ratings up to 36 W at a terminal temperature of 125 °C and operating temperatures from -40 °C to +125 °C.
Every CSI2F…
Large language models with hundreds of billions of parameters normally live in data centres, on servers with far more memory than any single-board computer. So it is a surprise to see one answer a question on an Arduino. In a project published on Arduino Project Hub, Jim Bruges ran GLM-5.3, a 744-billion-parameter model whose files take up about 419 GB, on an Arduino VENTUNO Q with just 16 GB…
Hioki is one of those Japanese test-equipment names that engineers associate with quality and with a high price, so a Hioki multimeter for 95 US dollars sounds like a fake. It isn't. The DT4215 is a genuine, Hioki-approved meter made in China and sold only for the Chinese market, and Dave Jones of EEVblog just bought one from AliExpress to tear it down. Inside he found input protection that is…
Marble machines usually stop at clocks, with a fixed number of digits and a fixed amount of space. Ivan Miranda wanted a display that never runs out of room. His new Marble Scroller is a huge 3D-printed wheel that writes text in black and white marbles using a 7x5 pixel font, lets each line roll off the other side and then recycles the same marbles to write the next one. It can do uppercase,…
Walk into almost any shop in India and you will hear it: a small speaker on the counter calling out "Rs 10 received" the moment a customer pays by UPI. Makers have built their own versions before, but almost all of them need a merchant account with a payment gateway, which most students and hobbyists simply don't have. Now techiesms has built an ESP32 payment soundbox that skips the merchant…
