Now why didn’t we think of this? While building a dactyl manuform — a semi-ergonomic split keyboard — [dapperrogue] had the life-changing epiphany that keyboards can be any shape or …read more

Although protocols like I2C and SPI are great for communicating between embedded devices and their peripherals, it can be a pain to interface these low-level digital interfaces to a PC. …read more

We all have too much stock of one component or another. Maybe you have more audio pots than you know what to do with, or maybe it’s zener diodes. For …read more

Sometimes it is hard to probe a circuit and then look over at the meter. [Electronoobs] decided to fix that problem by making a Google Glass-like multimeter using an OLED …read more

What happens when you have multiple signals you want to measure at a high accuracy but only one high-resolution digital multimeter? Assuming you don’t need to measure the signals simultaneously, you can opt to buy a scanning data acquisition system...

It seems that soy milk makers as a whole are a problematic bunch. From the Joyoung which had a motor that destroyed itself relatively quickly to the Soyoung which had a transformer thermal fuse open which was replaced and then...

PC-104 is a standard computer form factor that most people outside of industrial settings probably haven’t seen before. It’s essentially an Intel 486 processor with lots of support for standards …read more

OpenSCAD is a fantastic free tool for 3D modeling, but it’s far less intuitive to use for non-programmers than mouse-driven programs such as Tinkercad. Powerful as it may be, the …read more

The holiday mood continues with my final installment of images from Osaka from my trip back in 2017. In this section, I look at the more parks and a few day trip locations from Osaka including Ikeda, Mozu and Kobe....

[Wayne Venables], like many of us, found himself sitting more than usual the past few months.  Armed with a Bluetooth-enabled under desk exercise bike, he quickly found the app to …read more

Last month, I climbed Cerro Zapaleri, the 5648 m tall summit of which forms the tripoint of the borders of Chile, Argentina, and Bolivia.1 Its location is quite remote, ~105 km from San Pedro de Atacama, Chile and >40 km from the nearest...

For as much as we love reverse engineering projects, we have to admit that we almost passed up on this “kitchen bump bar” hack. Having never had the privilege of …read more

Few things get a Hackaday staffer excited like bunches of tiny LEDs. The smaller and denser the better, any form will do as long as we can get a macro …read more

Thomas Edison famously quipped “To invent, you need a good imagination and a pile of junk.” Amen, brother. My personal junk pile (ahem, collection of pre-owned electromechanical curiosities) is certainly …read more

The Raspberry Pi RP2040 chip is a remarkable microcontroller. The programmable IO block (PIO) is only one many great features of this chip. In this post, I show you a method how utilise PIO, to capture the speed of an...

Most people would recognize E.T. The Extra-Terrestrial for the Atari 2600 by its reputation as one of the worst video games of all time. We’ll have more to say about …read more

The first time [konbaasiang] ordered some ceiling LED lights from Tuya, he was pleased to find they contained an ESP-12F that could easily be flashed with a different firmware. So …read more

We speak from experience when we say that making pinball targets is harder than you might think. The surface area of the part of the ball that touches is oh-so-small, …read more

We like to pretend that our circuit elements are perfect because, honestly, it makes life easier and it often doesn’t matter much in practice. For a normal design, the fact …read more

On the face of it, a spot welder is a simple device. If you dump enough current through two pieces of metal very quickly, they’ll heat up enough to melt …read more

Looking for a hands-free way to page through sheet music on an iPad, [The_Larch] came up with this simple Bluetooth input device based on the ESP32. The microcontroller just needed …read more

It’s hot! Hotter than it used to be, and too hot for things to remain nice in the future. The sun keeps beating down, and as our greenhouse gas emissions …read more

The date was September 26, 1983. A lieutenant colonel in the Soviet Air Defence Forces sat at his command station in Serpukhov-15 as sirens blared, indicating nuclear missiles had been …read more

Hackaday editors Elliot Williams and Mike Szczys marvel at the hacks that surfaced over the past week. An eye-popping webcam hack comes in the form of an animatronic that gives …read more

Porting DOOM to run on hardware never meant to run it is a tradition as old as time. Getting it to run on embedded devices, ancient computers, virtual computers, and …read more
