Although once little more than an academic endeavor, the RISC-V architecture is slowly supplanting applications that would have normally gone to ARM. Even a few microcontrollers have chips running this …read more Continue reading 2026 Retrocomputing Challenge: Custom RISC-V Processor For Retro System
Although not technically the first virtual pet, the Tamagotchi handhelds certainly popularized the idea and made it a worldwide phenomenon. In the late 90s it was hard to go out …read more Continue reading Hacking the Modern Tamagotchi With UART
A few years ago, [Smashcat] ported a ZX Spectrum game called Manic Miner to the Arduino Uno. The Arduino has less memory than the original Spectrum did, so doing all this …read more Continue reading Arduino Engine Runs Many Games
The Kernel-based Virtual Machine (KVM) allows Linux systems to function as hypervisors without needing any extra software, but VMs created with it don’t behave exactly like real hardware does. Sometimes …read more Continue reading Hiding Virtualization From Other Software
Some of the first remote controls available to consumers used sound, visible light, or even just wires to communicate with their parent device. It was many years between these first …read more Continue reading Simple, Reliable RF Remote Control
These days we take high-speed networking for granted, but it can be difficult to get vintage computers talking to modern machines. To help solve this problem [jaime] came up with …read more Continue reading 2026 Retrocomputing Challenge: I Would Do Anything For Serial Data
The style and sound of older video games is unique enough that they’re still copied in relatively modern games like Undertale, Celeste, or Shovel Knight. There’s also a vibrant chiptune community making music …read more Continue reading Using an Unmodded GBA as a Music Synth
One of the major limits of mass-produced batteries is the electrolyte. From lead-acid to lithium ion, there’s some temperature where the electrolyte will freeze and cause all sorts of problems, …read more Continue reading NASA Batteries Survive Extreme Cold and Heat
For as many sensors, cameras, and computers as there are on modern cars, they ought to be a dream to poke around in and customize to one’s liking. Unfortunately they’re …read more Continue reading Car’s Camera Footage Backed up to NAS
When most radio enthusiasts start trying to pick up signals from satellites, they might put together a quick-and-dirty Yagi antenna and try to catch a repeater as is passes overhead, …read more Continue reading Going Whole-Hog on a First Satellite Ground Station
