The simple plasma ball – it graces science museums and classrooms all around the world. It shares a place with the Van de Graaf generator, with the convenient addition of spectacular plasma rays that grace it spherical surface. High voltage, aesthetically pleasing, mad science tropes – what would make a …read more
What’s the weirdest computer you can think of? This one’s weirder.
[Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor). The Dr. has since built AND, NAND, OR, NOR, XOR and XNOR gates, as well as …read more

This seven segment art display makes use of a 81 seven segment red common cathode LED displays. The LEDs are arranged onto 100x100mm boards that each contain an Arduino Nano and 9 seven segment displays, daisy chained through three-pin headers located on the sides of the boards. The pins (power, …read more
Can you generate VGA and handle a PS/2 keyboard with a Cortex-M4 in Rust? That’s precisely what [theJPster] wanted to find out with Monotron, a 1980s style home computer programmed in pure Rust.
In order to run embedded Rust without a working operating system, some tools are necessary: an LLVM …read more

While autonomous robots have been the subject of some projects in the past, this particular project takes a swing at building a robot that can teach children about controls and robotics.
The idea is to mimic a space mission on the dark side of the moon, where radio contact is …read more

This project would fit in perfectly with #BadgeLife if someone could figure out a way to hang it from their neck. Inspired by Star Trek’s Starship Enterprise, [bobricius] decided to design and assemble a miniature space ship PCB model, complete with 40 blinking LEDs controlled by an ATtiny85.
While the …read more
The purpose of Geometer becomes apparent when you realize its simplicity: [David Troetschel]’s project is to create an easily understandable design tool that encourages goal-oriented design. The kit comes with physical components and digital counterparts that can be combined in a modular way. They each have a specific geometry, which …read more

The Thing is an unassuming name for an ambitious project to build an FPGA board from easy to find components.
The project stems from an earlier build submitted to the 2018 Hackaday Prize by [Just4Fun] where two dev boards – an STM32-based Arduino and an Altera MAX II CPLD board …read more
The may very well be the smallest homemade TTL CPU we’ve ever seen. Measuring at one square inch, this tiny chip boasts 40 connections, an 8-bit databus, a 16-bit address bus, a 64 kB memory space, reset and clock inputs, and 5 V power lines.
TTL (transistor transistor logic) logic …read more
