Many of us have had the experience of viewing an artwork in a gallery, in which the eyes appear to follow one around the room. In our high-technology work, this no longer need be achieved with artistic skill. You can just build something that actually moves instead. Chartreuse is the creation of [alynton], and has […]
The Rubik’s Cube was a smash hit when it came out in 1974, and continues to maintain a following to this day. It can be difficult to solve, but many take up the challenge. The Arduino Rubik’s Solver is a robot that uses electronics and maths to get the job done. The system consists of […]
It’s been a long time coming but [Fran] finally has a DSKY display, a replica of the user interface display found in the Apollo Guidance Computer. The best part? It’s a t-shirt. This build is a long, long, time in the making first beginning in 2015 when Fran started investigating the DSKY of the Apollo […]
Before the invention of transistors, vacuum tubes ruled the world. The only way to get amplification or switching (or any electrical control of current) back then was to use tubes. But some tube design limitations were obvious even then. For one, they produce an incredible amount of heat during normal operation, which leads to reliability […]
We’ve seen backyard casting, and for the most part, we know what’s going on. You make a frame out of plywood or two by fours, get some sand, pack it down, and very carefully make a mold around a pattern. This is something else entirely. [FarmCraft101] is casting a bronze cannon. Sure, it’s scaled down […]

So, [peterbrazil]’s wife is a rural mail carrier on a small island. For her upcoming birthday, he wanted to build a lil’ something she could […]
In the world of Doctor Who, the sonic screwdriver is a versatile tool with a wide range of capabilities. [Hartley] wanted some of that action for himself, and built a device of his own. Unable to recreate the broad swathe of features from the show, he settled on something easier. The device is fitted with […]
The serial port remains a hacker staple, being one of the easiest ways to move a little bit of data from one machine to another. All manner of projects use the interface, and often, sensors are connected and their data read over such connections. In these cases, it can be useful to plot said data, […]
[MakeFailRepeat] was heading to MakerCentral in Birmingham, an event to which many makers were bringing coins to swap and trade. Wanting to get in on the action, he decided to etch some coins of his very own. Etching aluminium is a simple process, readily accessible to the average maker. [MakeFailRepeat] started with an aluminium bar, […]
Telegram is an instant messaging app, well known for its focus on security and encryption. It’s used by government officials, journalists, and the paranoid, and can also handle VoIP calls, in addition to its text messaging capability. [PiMaker] wondered if all this encryption could be put to good use, and decided to try and route […]
