Fail of the Week: Did My Laser Cutter Tube Really Burn Out?

Posted on by

All the cool kids are doing it these days, or more like for many years now: you can get a laser cutter for a song if you don’t mind doing your own repairs and upgrades — you know, being a hacker. The downside is that some failures can really ruin your day. This is what [Erich Styger] encountered with his cutter that is just a bit more than a year old. This Fail of the Week looks at the mysterious death of a CO2 laser tube.

This is the infamous K40 laser cutter. Our own [Adam Fabio] just took one …read more

The Metal That Never Forgets: Nitinol and Shape-Memory

Posted on by

You’ve likely heard of Nitanol wire before, but we suspect the common base knowledge doesn’t go much beyond repeating that it’s a shape-memory alloy. [Bill Hammack], the Engineer Guy, takes us on a quick journey of all the cool stuff there is to know about Nitinol and shape-memory alloys.

The name itself is like saying Kleenex when you mean tissue, or using the V-word when you mean hook and loop fasteners. The first few letters of Nickel Titanium Naval Ordnance Laboratories combine to form the name of what is essentially a nickel-titanium alloy developed in …read more

Disco Ain’t Dead: Blinky Ball Makes You Solder Inside a Dome

Posted on by

Disco balls take a zillion mirrors glued to a sphere and shine a spotlight on them. But what if the ball itself was the light source? Here’s a modern version that uses addressable LEDs in a 3D-printed sphere that also hides the electronics inside the ball itself.

Check out the video below to see the fantastic results. It’s a Teensy 3.6 driving a whopping 130 WS2812 LEDs to make this happen. (The sphere has the highest surface area to volume ratio!) There’s even a microphone and an accelerometer to make the orb interactive. Hidden inside is a 4400 mAh battery …read more

It Happened at Supercon: Six Days of Fun in a Three Day Con

Posted on by

A weekend for people who love hardware, by people who love hardware. It’s a simple recipe and it makes a delicious event that we call the Hackaday Superconference. If you made it to Pasadena last weekend, I’m sure going back to work on Monday was difficult after three days of far too little sleep and way too much fun. (It was for me.) If you didn’t make it to the con, set a reminder for July 1st to start watching for next year’s early bird tickets. Don’t believe me? Okay, let’s step through the hype of a weekend we’ll all …read more

Dexter Robotic Arm Wins the 2018 Hackaday Prize

Posted on by

Dexter, an open-source, high-precision, trainable robotic arm has just been named the Grand Prize winner of the 2018 Hackaday Prize. The award for claiming the top place in this nine-month global engineering initiative is $50,000. Four other top winners were also named during this evening’s Hackaday Prize Ceremony, held during the Hackaday Superconference in Pasadena, California.

This year’s Hackaday Prize featured challenges with five different themes. Entrants were asked to show their greatest Open Hardware Design, to build a Robotics Module, to design a Power Harvesting Module, to envision a Human Computer Interface, or to invent a new Musical Instrument. …read more

Livestream the Hackaday Superconference

Posted on by

The Hackaday Superconference is happening right now and you can join in on the Livestream. Talks begin at 10 am Pacific time on Saturday and Sunday.

The live stream covers one of two stages at the ultimate hardware conference. Topics focus on hardware creation, ranging from silicon chip fabrication, drop-in circuit designs, firmware frameworks, and 3D printing orbital rockets, to abusing printer cartridges, placing circuits on odd substrates, lighter-than-air electronics, and better techniques for building tech in garments, jewelry, props, and other wearables. Saturday evening you can watch as the Hackaday Prize is awarded live on stage, and Sunday afternoon’s …read more

Supercon is Sold Out, Join Us On the Live Streams and Chat Rooms

Posted on by

Over the weekend, the last available tickets to the Hackaday Superconference vanished. This will be the fullest, most exciting, hack-packed Supercon ever.

We’ve always had a stunning slate of speakers. It’s hard to objectively say we will top previous years, but yes this collection of talks is an insane concentration of hardware speakers that tops anything we’ve seen before. You can’t look at the schedule without feeling an electric jolt of excitement. The good news is you can still get in on those talks. Bookmark this Hackaday Superconference Live-Stream which begins at 10 am PDT on Saturday, November 3rd.

What the Hack Is This Thing?

Posted on by

Let’s play a guessing game. Shown here is a sneak peek at the rear view of a hardware demo being built specifically for the Hackaday Superconference in Pasadena this November 2-4. It’s sure to be a crowd pleaser when finished, but if you’re anything like us, studying what’s behind the finished face of a project like this is even more satisfying than seeing the final product.

If you think you know what it is, you can score yourself a free hardware badge from the conference! Leave a comment below with your best guess about what this is — we’ll pick …read more

The Supercon Badge is a Freakin’ Computer

Posted on by

It hangs around your neck, comes with the cost of admission, and would blow away a desktop computer from the 1980’s. This is the Hackaday Superconference badge and you can get your hands on one for the price of admission to the ultimate hardware conference.

Everyone through the door gets one of these badges featuring a 320 x 240 color display, a full qwerty keyboard, and limitless hacking potential! The stock firmware runs a BASIC interpreter, the CP/M operating system, and includes games and Easter Eggs. It’s a giant playground, and we want to see what you can do with …read more

Retrotechtacular: Robots and Bowling Pins

Posted on by

On a recent bowling excursion it occurred to us that this is one of the most advanced robotics systems most Americans will directly interact with. That’s a bold claim today, but certainly one that was correct decades ago. Let’s take a stroll back to 1963 for a look at the state of the art in bowling at the time, the AMF automatic pinspotter.

With their basis in industrial automation, bowling was a perfect problem for the American Machine and Foundry company (AMF) to take on. Their business began at the turn of the 20th century with automated cigarette manufacturing before …read more
