frank-dino: a RP2350B helper chip for a real Zilog Z80

rh1tech (Mikhail Matveev) has released frank-dino v1.00 on GitHub, the first firmware for the dino_z80 board. An RP2350B microcontroller acts as the whole machine around a real Zilog Z84C00 CPU, so the Z80 does the work and the RP2350B handles everything else: memory, video, sound and storage. It covers the ZX Spectrum 16K, 48K, 128K, […]

Google Doodle Pac-Man’s siren call

Marcin Wichary, writing on his blog Unsung, tells the story of the bug he shipped to Google’s homepage in 2010. He wrote the playable Pac-Man doodle for the game’s 30th anniversary, building the whole thing in HTML and CSS, with Flash handling the sound. The playfield spelled out Google’s logo, and a Ms. Pac-Man mode […]

Understanding DC motor principles

A project from electroniclovers on Hackster walks through how a DC motor turns current into rotation, using magnets, a copper loop and a 3D simulation to show the steps. It starts with two permanent magnets and the attraction between opposite poles. Next, current through a copper rod makes a magnetic field around it, and reversing […]

The Linux 7.4 merge window is easily the largest in kernel history

Michael Larabel, writing at Phoronix, reports that the Linux 7.4 merge window is the biggest one the kernel has ever had. The merge window is the two week stretch at the start of each kernel cycle when maintainers send in their changes for the next release. After it closes, the work moves to release candidates […]

MIT engineers design a safer, more efficient vaccination system for farmed fish

Zach Winn writes in MIT News about a team at MIT and the U.S. Department of Agriculture that built a new way to vaccinate farmed fish. Today the most effective method uses metal needles. Fish have to be sedated, lifted out of the water and injected one at a time. That’s slow and stressful for […]

Rooting an Amazon Echo Dot

Julian Imhof, writing on andystechlab.dev, turned a 2018 Echo Dot 3 into a local Home Assistant voice satellite. Amazon cloud isn’t used in handling the voice commands. The work needs a Linux computer, an open-source project, and a USB cable soldered to the board. The Echo Dot doesn’t have a USB socket, so the USB […]

An Italian Folding Bicycle Design that Fits Into a Suitcase

This T&C Pocket Bici is a folding bicycle made by Tresoldi & Casiraghi, an Italian metalworking firm, in 1963. Unlike the folding bicycles of today that split in half, the components here all fold into the racetrack-shaped frame. The whole thing then fits within its own suitcase. (Brompton bike in the photo for scale.) The bike's origin story is a bit murky; one auction site claims it was created specifically for the Chinese market, and that 2,500 units were sold. In contrast, BikeFlip says a Chinese group placed an initial order for 2,000 units, but that after T&C produced the first 1,000 uni

Industrial Design Student Work: A Hard Drive that Visually Indicates How Full It Is

This morphing hard drive enclosure is by Antonin Odin , done as an Industrial Design student at France's ENSCI . People increasingly want more visibility over their data, more taste in the objects they live with, and more function from both. ZO is a 12 TB personal server that gives storage a body. Empty, it's a plain aluminium tube. As it fills up, its fins slide out one by one, one millimetre for every 400 GB. Switched off, it keeps its shape: it shows what it holds. It's built to live on a shelf, rather than hide in a rack. An almost ritual object that makes what we entrust to the machine vi

Unidome's Transparent Igloos

Earlier we looked at the work of Dream Domes , a UK-based event structure company. They've worked out a way to erect large event tents with no central support. In the UK is another company called Unidome that also builds circular-footprint event structures, albeit smaller, and with transparent walls. Rather than being competitors, the two companies are collaborating. This year patrons of Glide , an ice skating rink located at the Battersea Power Station retail and dining complex, can rent these Unidome "igloos" for 90-minute periods. Dream Domes is doing the installation. Dream Domes says they

Automatic Drop Down Seals for Doors

The automatic door bottom is a clever bit of engineering that prevents under-door drafts, without installing a skirt that drags across your floor. Also called an automatic drop seal, it consists of an aluminum extrusion mounted in a dado cut into the bottom of the door. A little brass plunger protrudes from one end on the hinge side. As you close the door, the plunger is forced inside the assembly, where it triggers the spring-loaded seal to drop to the threshold, sealing the gap. Opening the door causes the seal to retract. Automatic door bottoms are useful not only for sealing drafts, but al

The Unique Fairings on Bandit9's RED 800 Motorcycle

You probably know of RED , Bono's organization that raises fund to fight preventable diseases, through their many collaborations with Apple and Jony Ive; there were special RED iPod Nanos, iPhones and even a Mac Pro. Now RED's moved into the motorsports space, partnering with motorcycle designer Daryl Villanueva. Villanueva's firm, Bandit9 , will be producing nine of these RED 800 Ducati-powered motorcycles: As you can see, rather than painting the entire thing red, Villanueva's opted to carefully fade a hand-painted finish into the brushed aluminum of the fairing. "Fewer parts," writes Villan

PureSelfMade's Build-Your-Own Wind Turbine Workshops

Since the 1970s, self-taught engineer Hugh Piggott has been building wind turbines from scratch in his native Scotland. In the 2000s, he started holding workshops showing participants how to build their own. Jonathan Schreiber, an Austrian renewable-energy practitioner, took Piggott's course in 2012. Piggott no longer teaches, but now Schreiber has picked up the mantle. He formed PureSelfMade , an independent-energy education project, and since 2013 has hosted workshops showing participants how to build Piggott's design. At these workshops, you do not assemble a wind turbine kit. Instead you l
