Since I took delivery of my Yamaha TW200 back in March, I have been riding it as much as I can. Its a little one-cylinder thumper with a (less than) whopping 14 horsepower output. It really can’t go on highways because it is too slow. They call it a tractor. I’ve been calling mine “Chubby”. …

WLED is custom firmware for controlling multi-colour LED lights. It's designed for string lights, with lots of individual LEDs that can be controlled independently. I've recently given it a try for the first time. ESP devices WLED runs on Espressif's ESP32 and ESP8266 chips (although the latter isn't recommended for new installs). That means it's...
A YouTuber going by Flamethrower spent nights listening to his brother's new hamster squeak through the exercise wheel and decided to harvest the energy. The result is a working phone charger powered by the rodent.
A hamster runs in bursts, while a phone wants steady voltage — that's the engineering problem. — Read the rest

Electrical circuits have always been a mystery to me. Those tiny components that look like Chiclets or jewelry beads somehow make a light blink, produce music, and detect motion. So I was happy to learn about _The Secret Life of Circuits: An Illustrated Guide to Electronic Circuit Design_ , a new 400-page book by Michal Zalewski from No Starch Press, due in fall 2026. — Read the rest

Electronics hobbyist Scott Lawson wanted to know which parts in his storage collection he actually reaches for, so he invented a tracking system that costs about $3: colored dot stickers from AliExpress. The rule is simple — every time he opens a storage box, he puts one dot on it. — Read the rest

Nirvaan Tandon started with Snap Circuits at four, learned programming at six, and encountered a Raspberry Pi at seven when he attended Coolest Projects, a showcase for young makers. Now 14, he's built a chess timer from a Raspberry Pi Pico W that's about the size of a king piece — compact enough to sit on the board between players, as described on the Raspberry Pi blog. — Read the rest

I am 47 years old and have been buying records — the vinyl kind, which, no hate, but we call, simply, “records” and not “vinyls” like younger generations have taken to calling them — for the better part of 30 years, and I’ve recently encountered a problem: I’m out of space. And not just shelf […]

The concept of a USB-C-based power supply is not new, and we have previously seen projects like XIAO Powerbread and Axiometa BrodBoost-C. As USB PD-based power adapters and power banks have become much cheaper, adjustable power supplies like the PocketPD and BenchVolt PD have come out. Both have their own limitation: the PocketPD has only a single output channel, thus hardly a lab power supply,…
Espressif’s ESP32-P4 revision 3.0 and greater converts pin 54 of the chip from NC (non-connected) to a power rail (VDD_HP_1), requires a few extra passives, and an updated firmware. Espressif Systems first unveiled the 400 MHz ESP32-P4 dual-core RISC-V SoC in January 2023, and the official ESP32-P4-Function-EV development board was launched in August 2024, with commercial solutions slowly ramping…
KiCad 10 open-source EDA software has just been released with support for dark mode, importers for Allegro, PADS, and gEDA/Lepton PCB, and various changes to the Schematic Editor (e.g., hop-over display) and the PCB Editor, notably adding a graphical DRC rule editor. KiCad 10 was built by hundreds of developers, translators, library contributors, and documentation submitters, who submitted 7,609…

Atek Midas, a Turkish company, has launched DSG-22.6 GHz, a high-performance, open-source RF signal generator designed to provide professional-grade frequency synthesis at a fraction of the cost of traditional benchtop equipment from manufacturers like Anritsu or Keysight. It has an operating frequency range of 0.15 GHz to 22.6 GHz and is designed for makers and production test environments for…

Adapters to use DSLR lenses on modern mirrorless cameras are very common parts of photography kits. They are extremely useful tools that enable photographers to use their existing, older lenses on new mirrorless cameras. However, as New Zealand builder James, who goes by Ancient on YouTube, shows, these adapters can be so much more and capture photos and videos that would otherwise be…
