An EDF (electric duct fan) is a motor that basically functions as a jet engine for RC aircraft. They’re built for speed, but to improve maneuverability (and because it’s super cool) …read more Continue reading Watch This RC Jet Thrust System Dance
We love hearing about a good experiment, and here’s a pretty neat one: researchers used a VR headset, an off-the-shelf VR360 camera, and some custom software to glue them together. …read more Continue reading Giving People an Owl-like Visual Field via VR Feels Surprisingly Natural
Some time ago [Kelton] was working on a clock inspired by Rube Goldberg contraptions. It uses only a single motor, and he’s proud to now show off the finished product …read more Continue reading Newly Completed Overly-Complex Clock Synchronizes Multiple Mechanisms
Rare earth elements are used to produce magnets with very high strength that also strongly resist demagnetization, their performance is key to modern motors such as those in electric vehicles …read more Continue reading Making EV Motors, And Breaking Up with Rare Earth Elements
8cc.vim is a C compiler that exists as pure Vimscript. Is it small? It sure is! How about fast? Absolutely not! Efficient? Also no. But does it work and is …read more Continue reading C Compiler Exists Entirely in Vim
When homebrewing a CPU, one has to deal with microcode. Microcode is the low-level nuts and bolts of how, precisely, a CPU executes instructions (like opcodes) and performs functions such …read more Continue reading Custom Microcode Compiler, Made in Google Sheets
Useless robots (or useless machines) are devices that, when switched on, exist only to turn themselves back off. They are fun and fairly simple builds that are easy to personify, …read more Continue reading Useless Robot Gets Cute, Has Personality
Large Language Models (LLMs) can produce extremely human-like communication, but their inner workings are something of a mystery. Not a mystery in the sense that we don’t know how an …read more Continue reading Peering Into The Black Box of Large Language Models
[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. …read more Continue reading A DIY Proximity Sensor, Using Just Scrap Parts and Software
Bug reporting doesn’t usually have a lot of visuals. Not so with the visionOS bug [Ryan Pickren] found, which fills a user’s area with screeching bats after visiting a malicious …read more Continue reading Bats Can No Longer Haunt Apple VR Headsets Via Web Exploit
