It might take you some time to understand what’s happening in the video that Hackaday alum [Moritz Sivers] shared with us. This is [Moritz]’s contribution for this year’s Pi Day – a machine that shows digits of Pi in a (technically, not quite) infinite loop, and shows us a neat trick we wouldn’t have thought of. The two main […]

The classic arcade game Cyclone has attracted many players, along with their coins, thanks to its simple yet addictive gameplay. In its most basic form it consists of a light racing around a circular track, which the player then has to stop at exactly the right place. Arduino enthusiast [mircemk] made a home version of this game, which

As any cat owner will tell you, a cat’s ears are great indicators of its state of mind: pointed forward if they want your attention, turned backwards if they’re angry, and folded down flat when they’re afraid. Humans sometimes don cat ear headbands as a fashion statement, but sitting motionless those ears are more likely

The official Arduino development team has this week announced that it is now possible to program the UNO Wifi Rev2, that comes with the Arduino CTC Go! kit using Chromebook computers. The announcement was made via the official Arduino blog. “So we’re pleased to announce that from today, educators and students who are using CTC GO! can

[Kevin] has long wanted to do something musical with a vintage rotary phone and an Arduino, and has finally done so and committed the first of several experiments to HTML in a five-part series. He found a nice old British Telecom number, but it had been converted to plug and socket wiring to work on the

Are you a math aficionado in need of a new desk toy? Then do we have the project for you. With nothing more than an Arduino and a seven-segment LED module, [Cristiano Monteiro] has put together a little gadget that will slowly work its way through the digits of Pi forever…or until you get bored of looking

When a person owns the home they live in, often the only approval they need for modifications is from their significant other or roommate. In the worst case, maybe a permit is required. But those who rent their dwellings are far more constrained in almost every case, and when it comes to environmental controls, they

I’m probably as guilty as anyone of reinventing the wheel for a subpart of a project. Heck, sometimes I just feel like working on a wheel design. But if that’s the path you choose, you have to think about whether or not it’s important that others can replicate your project. The nice thing about a bog-standard wheel
The UK in the 1980s was ground zero for the microcomputer revolution. Cheap computers based on 8-bit processors flooded the market, teaching a generation to program using built-in BASIC interpreters. Homes had devices like Sinclair’s ZX81 and Spectrum, while schools used Acorn’s BBC Micro. More about Innovation These weren’t like today’s PCs. They were designed

If you’ve ever wanted to build a large format plotter but didn’t have the floor space, maybe put it up against the wall and make it cute. That’s the idea behind Fumik, the wall-drawing robot. As you might expect, the little device is just a motion base with a pen. We hope there’s paper against the
