Modern microcontroller platforms spoil us with their performance and expansive spec sheets. These days it’s not uncommon to be developing for a cheap micro that has a clock rate well in excess of 100MHz, with all manner of peripherals baked in. DACs, WiFi, you name it – it’s in there, with a bunch of libraries […]
We often think of 3D printing as a way to create specific components in our builds, everything from some hard-to-find little sprocket to a custom enclosure. More and more of the projects that grace the pages of Hackaday utilize at least a few 3D printed parts, even if the overall build itself is not something […]
These days, you could be forgiven for thinking driving an LCD from a microcontroller is easy. Cheap displays have proliferated, ready to go on breakout boards with controllers already baked in. Load up the right libraries and you’re up and running in a matter of minutes. However, turn your attention to trying to drive a […]
Of all the retro systems, the Commodore 64 had the best video system. The VIC-II chip in the C64 was the best example of why Commodore was the best, but in terms of video output, the C64 was still a consumer device: the only output was S-video, or composite video, or something like it. The […]
It wasn’t that long ago that talking to computers was the preserve of movies and science fiction. Slowly, voice recognition improved, and these days it’s getting to be pretty usable. The technology has moved beyond basic keywords, and can now parse sentences in natural language. [Liz Meyers] has been working with the technology, creating WhatIsThat […]
Pen testing isn’t about evaluating inks. It is short for penetration testing — someone ensuring a system’s security by trying to break in or otherwise attack it. A company called Pen Test Partners made the news last week by announcing that high-end car alarm systems made by several vendors have a critical security flaw that […]
The hovercraft is an entertaining but much maligned form of transport. While they have military applications and at times have even run as ferries across the English Channel, fundamental issues with steering and braking have prevented us all driving them to work on a regular basis. They do make great toys however, and [HowToMechatronics] has […]
Debugging tools are critical to quick and effective development. Without being able to peek under the hood at what’s really going on, it can be difficult to understand and solve problems. Those who live on the Arduino platform are probably well acquainted with using the serial port to debug, but it’s far from the only […]
It’s possible to find surplus LCDs in all kinds of old hardware. Photocopiers, printers – you name it, there’s old junk out there with displays going to waste. Unfortunately, unlike the displays on sale at your favourite maker website, these often lack a controller and can be quite difficult to drive. [pataga] took on the […]
There’s something oddly menacing about some vacuum tubes. The glass, the glowing filaments, the strange metal grids and wires suspended within – all those lead to a mysterious sci-fi look and the feeling that strange things are happening in there. Add in a little high voltage and a tube that makes its own hydrogen, and […]
