Using IMUs For Odometry

Posted on by

The future is autonomous robots. Whether that means electric cars with rebranded adaptive cruise control, or delivery robots that are actually just remote control cars, the robots of the future will need to decide how to move, where to move, and be capable of tracking their own movement. This is the problem of odometry, or how far a robot has traveled. There are many ways to solve this problem, but GPS isn’t really accurate enough and putting encoders on wheels doesn’t account for slipping. What’s really needed for robotic odometry is multiple sensors, and for that we have [Pablo] and …read more

Building An Ultralight In A Basement is Just So Beautiful to See

Posted on by

[Peter] is at it again. Not content with being one of the best RC confabulators on YouTube, and certainly not content with the first airplane he built in his basement, [Peter Sripol] is building another airplane in his basement.

The first airplane he built was documented on YouTube over a month and a half. It was an all-electric biplane, built from insulation foam covered in fiberglass, and powered by a pair of ludicrously oversized motors usually meant for large-scale RC aircraft. This was built under Part 103 regulations — an ultralight — which means there were in effect no regulations. …read more

Making Electronics Just Got 25% More Expensive In The US

Posted on by

As reported by the BBC, the United States is set to impose a 25% tariff on over 800 categories of Chinese goods. The tariffs are due to come into effect in three weeks, on July 6th. Thousands of different products are covered under this new tariff, and by every account, electronic designers will be hit hard. Your BOM cost just increased by 25%.

The reason for this tariff is laid out in a report (PDF) from the Office of the United States Trade Representative. In short, this tariff is retaliation for the Chinese government subsidizing businesses to steal market share …read more

Two Awesome Ender’s Achievements

Posted on by

The Hackaday Prize is all about empowering you with the tools you need to create the next great hardware device. To that end, we’ve set up seed funding for your projects, we’ve given you a project hosting site, and most importantly, Hackaday gives you the opportunity to connect with tens of thousands of like-minded hardware hackers across the globe.

Not all hackers are out tinkering in their garage after work. Some are pulling the night shift in their dorm rooms, balancing classes, homework, hacking, and life. Student hackers, we salute you with the Ender’s Achievement!

The Modular Universal Jamming Gripper …read more

Folding Robots With Special Materials

Posted on by

When it comes to robots, we usually see some aluminum extrusion, laser-cut parts, maybe some 3D printed parts, and possibly a few Erector sets confabulated into a robot arm. This entry for the Hackaday Prize is anything but. It’s a robot chassis, a 3D printer, and the structural frame for any sort of moving project that’s made out of a special composite material.

[Marc]’s project for the Hackaday Prize is all about articulated mechanisms. Instead of the usual structural components, he’s using Hylite, a special material that’s basically a polypropylene core clad in a sheet of aluminum on both sides. …read more

Friday Hack Chat: All About The Hackaday Prize

Posted on by

Right now we’re neck deep in the Hackaday Prize. What’s the Hackaday Prize? It’s the Academy Awards of hardware creation, or at least that’s what we’re calling it until we get a cease and desist from the Academy of Motion Picture Arts and Sciences.

Already we’ve seen over eight hundred entries in the Hackaday Prize, and there are still months to go. We’re already through the Open Hardware Design Challenge, and twenty fantastic projects from that are moving onto the final round. Yesterday, we announced the winners of the Robotics Module challenge, and again we were blown away. These are …read more

These Twenty Amazing Projects Won The Robotics Module Challenge

Posted on by

Right now, we’re running the greatest hardware competition on the planet. The Hackaday Prize is the Academy Awards of Open Hardware, and we’re opening the gates to thousands of hardware hackers, makers, and artist to create the next big thing.

Last week, we wrapped up the second challenge in The Hackaday Prize, the Robotics Module challenge. Now we’re happy to announce twenty of those projects have been selected to move onto the final round and have been awarded a $1000 cash prize. Congratulations to the winners of the Robotics Module Challenge portion of the Hackaday Prize. Here are the winners, …read more

PCBs As Linear Motors

Posted on by

PCBs are exceptionally cheap now, and that means everyone gets to experiment with the careful application of copper traces on a fiberglass substrate. For his Hackaday Prize entry, [Carl] is putting coils on a PCB. What can you do with that? Build a motor, obviously. This isn’t any motor, though: it’s a linear motor. If you’ve ever wanted a maglev train on a PCB, this is the project for you.

This project is a slight extension of [Carl]’s other PCB motor project, the aptly named PCB Motor. For this project, [Carl] whipped up a small, circular PCB with a few …read more

Ask Hackaday: What Color Are Your PCBs?

Posted on by

A decade ago, buying a custom-printed circuit board meant paying a fortune and possibly even using a board house’s proprietary software to design the PCB. Now, we all have powerful, independent tools to design circuit boards, and there are a hundred factories in China that will take your Gerbers and send you ten copies of your board for pennies per square inch. We are living in a golden age of printed circuit boards, and they come in a rainbow of colors. This raises the question: which color soldermask is most popular, which is most desirable, and why? Seeed Studio, a …read more

Hackaday Links: Benchoff Rants On Flying Cars

Posted on by

It’s time for Computex, and that means [Linus] has dropped something. I don’t know what, but he’s dropped something. It’s a meme or something at this point. What were the highlights? Asus announced Project Precog, a laptop with two screens. Yes, a touchscreen keyboard. It’s the 2018 version of the IBM Transnote or whatever that Microsoft thing was called. Why is it called Project Precog? Because AI or whatever. Unimaginative marketing is terrible. Intel is going to launch a 28-core CPU, and AMD is introducing a 32-core CPU. Awesome, core wars. And here’s RGB RAM because stuffing a case full …read more
