Elliot Williams and Mike Szczys walk through the past week in hackerdom. There’s a new jargon quiz! Do you know what astrictive robotic prehension means? We look at the $50 Ham series, omni-wheeled pen plotting robots, a spectrum of LED hacks, LEGO CNC for chocolate rework, and grinding lenses with a CNC mill. In the […]
Last week , I covered the ridiculously low barriers to entry to amateur radio, both in terms of financial outlay and the process of studying for and passing the FCC examination. You’ve had seven days, so I assume that you’ve taken the plunge and are a freshly minted amateur radio operator. The next big question […]
The White House’s proposed budget for 2020 is out, and with it comes cuts to NASA. The most important item of note in the proposed budget is a delay of the Space Launch System, the SLS, a super-heavy lifting launch vehicle designed for single use. The proposed delay would defer work on the enhanced version […]
Knowing in what absolute direction your robot is pointed can be crucial, and expensive systems like those used by NASA on Mars are capable of calculating this six-dimensional heading vector to within around one degree RMS, but they are fairly expensive. If you want similar accuracy on a hacker budget, this paper shows you how […]
“Don’t Be Evil” was the mantra of Google from years before even Gmail was created. While certainly less vague than their replacement slogan “Do the Right Thing”, there has been a lot of criticism directed at Google over the past decade and a half for repeatedly being at odds with one of their key values. […]
Join us Wednesday at noon Pacific time for the Learning Through Play Hack Chat! You may think you’ve never heard of Greg Zumwalt, but if you’ve spent any time on Instructables or Thingiverse, chances are pretty good you’ve seen some of his work. After a long career that ranged from avionics design and programming to video game […]
Do you like hamburgers? Everyone likes hamburgers. Inspired by a phone you could buy at Spencers in 1991, [Love Hulten] built a Game Burger Advance. The guts are a Raspberry Pi Zero, a standard LCD display and what appears to be a USB control pad. The fabrication is where this one really goes crazy. It’s […]
Catch up on the past week of hacks with Hackaday Editors Elliot Williams and Mike Szczys. “AI on the Edge” is the buzzword of choice lately, with hardware offerings from BeagleBone and Google to satiate your thirst. We take on spotty data from Tesla, driving around on four bouncy-houses, reverse engineering a keytar, unearthing a […]
Today we start a new series dedicated to amateur radio for cheapskates. Ham radio has a reputation as a “rich old guy” hobby, a reputation that it probably deserves to some degree. Pick up a glossy catalog from DX Engineering or cruise their website, and you’ll see that getting into the latest and greatest gear […]
If you missed it, the Hackaday Supercon 2018 badge was a complete retro-minicomputer with a screen, keyboard, memory, speaker, and expansion ports that would make a TRS-80 blush. Only instead of taking up half of your desk, everyone at the conference had one around their neck, when they weren’t soldering to it, that is. The […]
