Extraterrestrial Autonomous Lander Systems to Touch Down on Mars

Posted on by

The future of humans is on Mars. Between SpaceX, Boeing, NASA, and every other national space program, we’re going to Mars. With this comes a problem: flying to Mars is relatively easy, but landing a large payload on the surface of another planet is orders of magnitude more difficult. Mars, in particular, is tricky: it has just enough atmosphere that you need to design around it, but not enough where we can use only parachutes to bring several tons down to the surface. On top of this, we’ll need to land our habitats and Tesla Roadsters inside a very small …read more

The Internet of Blast Gates

Posted on by

There’s nothing quite like building out a shop filled with tools, but even that enviable task has a lot of boring work that goes into it. You’ve got to run power, you’ve got to build benches, and you need to build a dust collection system. That last one is usually just fitting a bunch of pipe and tubes together and adding in a few blast gates to direct the sucking of your dust collection system to various tools around the shop.

For most shops with a handful of tools and dust collection ports, manually opening and closing each blast gate …read more

A Remote Controlled Air-Plane

Posted on by

The Air Hogs Sky Shark was a free-flying model airplane powered by compressed air. When it was released in the late ’90s, it was a fairly innovative toy featuring a strikingly novel compressed air engine made entirely out of injection molded plastic. Sales of these model planes took off, and landed on the neighbor’s roof, never to be seen again.

A few weeks ago, [Tom Stanton] revisited this novel little air-powered motor by creating his own 3D printed copy. Yes, it worked, and yes, it’s a very impressive 3D print. That build was just on a workbench, though, and to …read more

What You Need To Know About The Intel Management Engine

Posted on by

Over the last decade, Intel has been including a tiny little microcontroller inside their CPUs. This microcontroller is connected to everything, and can shuttle data between your hard drive and your network adapter. It’s always on, even when the rest of your computer is off, and with the right software, you can wake it up over a network connection. Parts of this spy chip were included in the silicon at the behest of the NSA. In short, if you were designing a piece of hardware to spy on everyone using an Intel-branded computer, you would come up with something like …read more

Hackaday Links: December 10, 2017

We have a contest going on right now challenging you to do the most with a coin cell. There are already quite a few interesting entries, and a few Hackaday writers are getting into the action by asking the question, ‘how do you open up a coin cell?’. The first thoughts were to open a lithium coin cell up while submerged in oil, but eBay came to the rescue with the cases for CR2025 cells. Of course that’s a thing.

Also falling into the, ‘of course that’s a thing’ category, there’s a project on Hackaday.io to execute arbitrary code on …read more

Sarah Petkus On Building A Cartoon To Go To Mars

Posted on by

Sarah Petkus is a robot mom (which means she’s the mother to a robot, not that Sarah herself is a robot, at least as far as we’re aware), whose child, Noodle Feet, is a character in Sarah’s graphic novel Gravity Road. Unlike every other robot on the planet, Noodle Feet is a content-based robot. Instead of robotic arms welding car panels together or 3D printers squiring out goo, Noodle Feet isn’t a robot built for a specific function. Noodle Feet’s design is derived from his personality in his graphic novel. In the graphic novel, Noodle Feet tastes with his feet, …read more

Friday Hack Chat: Contributing To Open Source Development

Posted on by

Open Source is how the world runs. Somewhere, deep inside the box of thinking sand you’re sitting at right now, there’s code you can look at, modify, compile, and run for yourself. At every point along the path between your router and the horrific WordPress server that’s sending you this webpage, there are open source bits transmitting bytes. The world as we know it wouldn’t exist without Open Source software.

That said, how does someone contribute to Open Source? Maintainers do like to build their own little kingdoms, so how does anyone break into developing Open Source hardware and software? …read more

CNC Calculator Does What You Can’t

Posted on by

The Hackaday community — and the greater hacker community — can do absolutely anything. Readers of Hackaday regularly pilot spaceships. The transmutation of the elements is a simple science project here, one easily attainable by a high school student. Hackaday readers have solved international crises, climbed Everest, and one day we’re going to have readers accessing Hackaday from an IP address on Mars. There is almost no limit to what our community can do.

This project does the one thing Hackaday readers are utterly incapable of doing. As a cool little bonus, the enclosure for this device is a beautiful …read more

Remember the Psion? Back when PDAs were a thing, the Psion was the best you could get. It was, effectively, a palm-top computer with a real qwerty keyboard. It didn’t have Bluetooth, it couldn’t browse the web, and it didn’t have WiFi, but this was an AA-powered productivity machine that could fit in your pocket. Now there’s a new palmtop from Psion engineers. The Gemini PDA is basically a smartphone with a real keyboard that runs Ubuntu. It’s also has a smaller battery than other devices with this form factor, meaning the TSA thinks it’s a smartphone. This thing is …read more
