[Anton Gaia]’s SPIRAL sculpture resembles an organizer or modern shelving unit, but what’s really interesting is how it goes together. It’s made entirely from assembling copies of a single component (two, if you count the short ‘end pieces’ as separate) without a fastener in sight. [Anton] made the 3D model available, so check it out […]
All-in-one computers in which the mainboard lurked beneath a keyboard were once the default in home computing, but more recently they have been relegated to interesting niche devices such as the Raspberry Pi 400 and 500. The Bento is another take on the idea, coming at it not with the aim of replacing a desktop […]
If he’s anything like us [Duncan Hall] was probably equal parts excited and disgusted when he found a 1987 Macintosh SE case at a garage sale. Excited, because not every day do vintage computers show up at these things. Disgusted, because it had been gutted and coated in house paint; the previous owner apparently wanted […]
When [Ben Eater] talks, hackers everywhere listen. In his latest video [Ben] shows us how to make computer noises using square waves and a 6502 microprocessor. [Ben] uses the timer in the W65C22 Versatile Interface Adapter to generate the square waves which generate a tone. He then adds support for a new BEEP command into […]
When we were kids, it was a rite of passage to read the newly arrived Edmund catalog and dream of building our own telescope. One of our friends lived near a University, and they even had a summer program that would help you measure your mirrors and ensure you had a successful build. But most […]
We’ve seen a lot of projects based on the Pi Pico, but a nuclear reactor simulation is a new one. This project was created by [Andrew Shim], [Tyler Wisniewski] and another group member for Cornell’s ECE 4760 class on embedded design (which should silence naysayers who think the Pi Pico can’t be a “serious” microcontroller), […]
It’s sometimes useful for a system to not just have a flat 2D camera view of things, but to have an understanding of the depth of a scene. Dual RGB cameras can be used to sense depth by contrasting the two slightly different views, in much the same way that our own eyes work. It’s […]
