One of the most basic problems with robotic arms and similar systems is keeping the weight down, as more weight requires a more rigid frame and stronger actuators. Cable-driven systems are a classic solution, and a team of researchers from MIT and Zhejiang University recently shared some techniques for designing fully 3D printed cable-driven mechanisms. […]
We’ve all seen those cheap bench power supply units (PSUs) for sale online, promising specifications that would cost at least a hundred dollars or more if it were a name brand model. Just how much of a compromise are these (usually rebranded) PSUs, and should you trust them with your electronics? Recently [Denki Otaku] purchased […]
“If there’s one thing the Commodore 64 is missing, it’s a large language model,” is a phrase nobody has uttered on this Earth. Yet, you could run one, if you so desired, thanks to [ytm] and the Llama2.c64 project! [ytm] did the hard work of porting the Llama 2 model to the most popular computer […]
You know how it is. You’re all cozy in bed but not quite ready to doze off. You’re reading Hackaday (Hackaday is your go-to bedtime reading material, right?) or you’re binge-watching your latest reality TV obsession on your tablet. You feel the tablet growing heavier and heavier as your arms fatigue from holding it inches […]
If you’ve got a popular 3D printer that has been on the market a good long while, you can probably get any old nozzles you want right off the shelf. If you happen to have an AnyCubic printer, though, you might find it a bit tougher. [Startup Chuck] wanted some specific sized nozzles for his […]
Dan Maloney and I were talking on the podcast about his memories of the old electronics magazines, and how they had some gonzo projects in them. One, a DIY picture phone from the 1980s, was a monster build of a hundred ICs that also required you to own a TV camera. At that time, the […]
In the Microchip tinyAVR 0-series, 1-series, and 2-series we see Configurable Custom Logic (CCL) among the Core Independent Peripherals (CIP) available on the chip. In this YouTube video [Grug Huhler] shows us how to make your own digital logic in hardware using the ATtiny CCL peripheral. If you have spare pins on your tinyAVR micro […]

A common ratchet from your garage may work wonders for tightening hard to reach bolts on whatever everyday projects around the house. However, those over at [Chronova Engineering] had a particularly unusual project where a special ratchet mechanism needed to be developed. And developed it was, an absolutely beautiful machining job is done to create […]
[sprite_tm] had a problem. He needed a clock for the living room, but didn’t want to just buy something off the shelf. In his own words, “It’s an opportunity for a cool project that I’d rather not let go to waste.” Thus started a project to build a fun e-paper digit clock! There were several […]
