There are a whole bunch of different ways to create 3D scans of objects these days. Researchers at the [UW Graphics Lab] have demonstrated how to use a small, cheap time-of-flight sensor to generate scans effectively. Not yet perfect, but the technique does work… The key is in how time-of-flight sensors work. They shoot out […]
Carving pumpkins by hand is hot, sweaty, messy work, and a great way to slice your way into a critical artery. Why not let a water jet do it for you? It’ll be cleaner and more precise to boot, and [Jo_Journey] is here to show us how. So sharp! Obviously, you’ll need a water jet […]
Like so many of us, [aforsberg] found themselves fascinated with the WOPR computer from WarGames — something about all those blinking LEDs must speak to nerds on some subconscious level. But rather than admire the light show from afar, they decided to recreate it at a scale suitable for a 1U server rack. So what […]
While not impossible, replicating the machines and processes of a modern semiconductor fab is a pretty steep climb for the home gamer. Sure, we’ve seen it done, but nanoscale photolithography is a demanding process that discourages the DIYer at every turn. So if you want to make semiconductors at home, it might be best to […]
Something that you generally don’t expect as a North-America-based enthusiast, is to listen in on Russian military communications during their war in Ukraine via WebSDR, or that these communications would be passing through US military satellites that are happy to just broadcast anything. Yet that’s the situation that the Saveitforparts YouTube channel recently described. As it […]
[James Sharman] designed and built his own 8-bit computer from scratch using TTL logic chips, including a VGA adapter, and you can watch it run a glorious rotating cube demo in the video below. The rotating cube is the product of roughly 3,500 lines of custom assembly code and looks fantastic, running at 30 frames […]
This week, Jonathan Bennett talks Rocky Linux with Gregory Kurtzer and Krista Burdine! Where did the project come from, and what’s the connection with CIQ and RESF? Listen to find out! CentOS primer Migration from CentOS Rocky Linux RESF FAQ CIQ Open Source Ethos Did you know you can watch the live recording of the […]
Those of us who worked in TV repair shops, back when there was such a thing, will likely remember the cardinal rule of TV repair: Never touch the yoke if you can help it. The complex arrangement of copper wire coils and ferrite beads wrapped around a plastic cone attached to the neck of the […]
We get it. We also watched Star Trek and thought how cool it would be to talk to our computer. From Kirk setting a self-destruct sequence, to Scotty talking into a mouse, or Picard ordering Earl Grey, we intuitively know that talking to a computer is better than typing, right? Well, computers talking back and […]
It is easy to forget that many technology juggernauts weren’t always the only game in town. Ethernet seems ubiquitous today, but it had to fight past several competing standards. VHS and Blu-ray beat out their respective competitors. But what about USB? Sure, it was off to a rocky start in the beginning, but what was […]
