ARDUINO BOT ROCKS A PS2 CONTROLLER

As far as controlling robots goes, makers today are spoilt for choice. WiFi and Bluetooth enabled microcontrollers are a dime a dozen, and integration with smartphone apps is a cinch. Despite this, the old methods still hold sway, as [Igor Fonseca] demonstrates with a simple Arduino bot. It’s a classic build, using a tracked chassis with a pair of motors providing propulsion and skid steering. The moto ...

WALL-MOUNTED GROUND STATION TAMES UNRULY SATNOGS NODE

For many of us, ad hoc projects end up having a certain permanence to them. Think of the number of Raspberry Pis and RTL-SDRs that are just dangling from a USB cable under a desk or stuffed behind a monitor, quietly going about their business. If it ain’t broke, don’t fix it. Some projects, though, just end up accreting past the acceptable point. This wall-mounted SatNOGS ground station is a great ...

SMART BUOY RIDES THE CITIZEN SCIENCE WAVE

Those beautiful and dangerous ocean waves that beckon us to the coast are more than just a pretty sight. They can tell us a lot about weather patterns and what the sea itself is doing. As vital as this information is, the existing methods of doing wave research are pretty expensive. The team at [t3chflicks] wanted to show it can be done fairly cheaply, to encourage more citizen scientists to contribute. Mor ...

CORE ROPE MEMORY MAKES ONE OF THE ODDEST LED FLASHERS WE’VE EVER SEEN

If you’ve heard of core rope memory, it will probably be in the context of vintage computing equipment such as Apollo-era NASA hardware. A string of magnetic cores and sense wires form a simple ROM arrangement, which though long-ago-superceded by semiconductor memory remains possible to recreate by the experimenter. It’s a path [Nicola Cimmino] has trodden, as he’s not only made a few nibbles of core rope m ...

BIG AND GLOWY TETRIS VIA ARDUINO

Tetris was a breakout hit when it was released for the Nintendo Game Boy in 1989, in much the same way that Breakout was a breakout hit in arcades in 1976. Despite this, gamers of today expect a little more than a tiny monochrome LCD with severe motion blur problems. Enter the LED Tetris build from [Electronoobs]. The build relies on a hacker favourite, the WS2812B LED string. The LEDs a ...
