3D Printing An Entire Rocket

Posted on by

If you’re ever flying into LAX and have the left side window seat, just a few minutes before landing, look out the window. You’ll see a small airport just below you and what appears at first glance to be a smokestack. That’s not a smokestack, though: that’s a rocket, and that’s where SpaceX is building all their rockets. Already SpaceX has revolutionized the aerospace industry, but just down the street there’s another company that’s pushing the manufacturing of rocket engines a bit further. Relativity Space is building rockets. They’re 3D printing rocket engines, and they’re designing what could be the …read more

No Moving Parts: Phased Array Antennas Move While Standing Still

Posted on by

If you watch old science fiction or military movies — or if you were alive back in the 1960s — you probably know the cliche for a radar antenna is a spinning dish. Although the very first radar antennas were made from wire, as radar sets moved higher in frequency, antennas got smaller and rotating them meant you could “look” in different directions. When most people got their TV with an antenna, rotating those were pretty common, too. But these days you don’t see many moving antennas. Why? Because antennas these days move electrically rather than physically using multiple antennas …read more

Adventures in Automating a Candle Factory

Posted on by

Have you ever considered the manufacture of candles? Not necessarily manufacturing them yourself, but how they are manufactured in a small-scale industrial setting? It’s something that has been of great concern to Michael Schuldt as he grappled with the task of automating a simple manual candle production process.

It’s not just an interesting subject, but the topic of manufacturing automation is something we can all learn from. This was the subject of his Adventures in Manufacturing Automation talk at the recent Hackaday Superconference which you’ll find below the break. Let’s dive in and see what this is all about!

Towards Low Cost Biomedical Imaging

Posted on by

Medical imaging is one of the very best applications of technology — it allows us to peer inside of the human body without actually performing surgery. It’s non-destructive testing to the extreme, and one of the more interesting projects we’ve seen over the past year uses AC currents and an infinite grid of resistors to image the inside of a living organism. It’s called Spectra and it is the brainchild of [Jean Rintoul]. Her talk at the Hackaday Superconference is all about low cost and open source biomedical imaging.

We’ve seen some interesting medical imaging hacks in the Hackaday Prize …read more

Designing Tiny Motors Right Into The Robot’s Circuit Board

Posted on by

Motors are not overly complex, but this one is downright simple. Carl Bujega has been working on a motor design that heavily relies on the capabilities of the printed circuit board (PCB) fabrication processes. His talk at the 2018 Hackaday Superconference covers how he built a brushless DC motor and speed controller into a PCB. You can watch the newly published video after the break.

There are two main parts of an electric motor; the stator is stationary while the rotor spins on bearings. Electromagnetic forces are used to cause that spinning action. In this case, Carl has built the …read more

The Art of Vacuum Tube Fabrication

Posted on by

Vacuum tubes fueled a technological revolution. They made the amplification of signals a reality for transatlantic telephone cables (and transcontinental ones too), they performed logic for early computers, and they delivered that warm fuzzy sound for high fidelity audio. But they were labor intensive to produce, and fragile, so semiconductors came along and replaced tubes in almost every application. But of course tubes are still with us and some tube applications are still critical — you’ll find them used in high-power RF and there are even satellites that depend on klystrons. So there are still experts in tube fabrication around, …read more

How a Microcontroller Hiding in a USB Port Became an FPGA Hiding in the Same

Posted on by

When you think of microcontroller development, you probably picture either a breadboard with a chip or a USB-connected circuit board. But Tim Ansell pictured an ARM dev board that is almost completely hidden inside of a USB port. His talk at the 2018 Hackaday Superconference tells that story and then some. Check out the newly published video, along with more details of the talk, after the break.

Tim is the creator of Tomu, the tiny ARM Cortex M0+ board that we first covered back in January. The board has a Silicon Labs EMF32 on one side, four traces to interface …read more

Oh the Lessons You’ll Learn by Building a Robot Familiar

Posted on by

A familiar spirit, or just a familiar, is a creature rumored to help people in the practice of magic. The moniker is perfect for Archimedes, the robot owl built by Alex Glow, which wields the Amazon AIY kit to react when it detects faces. A series of very interesting design choices a what really gives the creature life. Not all of those choices were on purpose, which is the core of her talk at the 2018 Hackaday Superconference.

You can watch the video of her talk, along with an interview with Alex after the break.

Radio Gets Ridiculous

Posted on by

There were plenty of great talks at this year’s Supercon, but we really liked the title of Dominic Spill’s talk: Ridiculous Radios. Let’s face it, it is one thing to make a radio or a computer or a drone the way you are supposed to. It is another thing altogether to make one out of things you shouldn’t be using. That’s [Dominic’s] approach. In a quick 30 minutes, he shows you two receivers and two transmitters. What makes them ridiculous? Consider one of the receivers. It is a software designed radio (SDR). How many bits should an SDR have? How …read more

Kitty Yeung On Tech-Fashion Designs and the Wearables Industry

Posted on by

If there is a field which has promise verging on a true breakout, it is that of wearable electronics. We regularly see 3D printing, retrocomputing, robotics, lasers, and electric vehicle projects whose advances are immediately obvious. These are all exciting fields in which the Hackaday community continually push the boundaries, and from which come the astounding pieces of work you read on these pages daily. Of course the projects that merge textiles and electronics are pushing boundaries in the same way, except for that it’s often not obvious at first glance. Why is that?

Wearables are a field in which …read more
