Sure, you can play a bunch of retro games on a Raspberry Pi, but if you’re really hardcore, you build your own retro console and write your own games for it. [Nicola Wrachien]’s entry into this year’s Hackaday prize is his DIY Cortex M0+ game console and the platform game he wrote to test the […]
Testing is a key part of any product development cycle. Done right, it turns up unknown bugs and problems, and allows for them to be fixed prior to shipment. However, it can be a costly and time-consuming process. The [Bay Libre] team needed to do some work on power management, but the hardware required was […]
To a speaker of English, a sign asking ‘Was?” may not make much sense. In German, however, the question is a more thought-provoking “What?” That’s exactly the point of this faux-neon sign created by [noniq]. The sign uses silicone-enclosed “neon-like” LED strips to spell out the question for all to see — and ponder. While […]
We’ve reported on the world of electronic badges here at Hackaday since their earliest origins in [Joe Grand]’s work for DEF CON 14 in 2006. In that time we’ve seen an astonishing variety of creations, covering everything from abstract artwork to pure functionality in a wearable device. But it’s not been quite so often that […]
Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular attachment. The picture above (and this older link) shows everything you need to know: the bottom of the coupling is mounted to […]
Which to buy first, a lathe or a mill? It’s a tough question for the aspiring home machinist with limited funds to spend on machine tools, but of course the correct answer is a lathe. With a lathe, we are told, all other machine tools can be built, including a milling machine. Granted that might […]
Sorting trash into the right categories is pretty much a daily bother. Who hasn’t stood there in front of the two, three, five or more bins (depending on your area and country), pondering which bin it should go into? [Alvaro Ferrán Cifuentes]’s SeparAItor project is a proof of concept robot that uses a robotic sorting […]
