Imaging Magnetism With A Hall Effect Camera

Posted on by

[Peter Jansen] is the creator of the Open Source Tricorder. He built a very small device meant to measure everything, much like the palm-sized science gadget in Star Trek. [Peter] has built an MRI machine that fits on a desktop, and a CT scanner made out of laser-

cut plywood. Needless to say, [Peter] is all about sensing and imaging.

[Peter] is currently working on a new version of his pocket sized science tricorder, and he figured visualizing magnetic fields would be cool. This led to what can only be described as a camera for magnetism instead of light. …read more

Inside This Year’s Queercon Badge

Posted on by

At this point, it’s not really correct to describe DEF CON as a single, gigantic conference for security, tech, and other ‘hacky’ activities. DEF CON is more of a collection of groups hosting villages, get-togethers, meetups, and parties where like-minded individuals share their time, company, electronic war stories, and whiskey. One of the largest groups measured by the number of rideable, inflatable unicorns is Queercon, a ‘conference within a conference’ dedicated to LGBT causes, a rager of a party, and a killer conference badge.

The Queercon badge is always a work of art, and this year is no exception. Last …read more

Hackaday Links: August 6th, 2017

Posted on by

We get a lot of Kickstarter pitches in our email, but this one is different. First of all, it’s over. No biggie there. Secondly, it’s a laser-cut hurdy gurdy. What’s a hurdy gurdy? It’s a musical instrument that uses a wheel to vibrate strings. It has drone strings and a rudimentary keyboard for the melody. Think of it as ‘string bagpipes’ and you’re not that far off. This means you can laser cut (or 3D print, someone get on it) a hurdy gurdy, and that’s just awesome.

I wrote the previous paragraph without referencing Donovan. You’re welcome, Internet.

Hackaday Prize Best Product Finalist: PewPew

Posted on by

This year for the Hackaday Prize, we’re doing something very, very cool. We’re encouraging hardware entrepreneurs to come up with the next big electronic thing. We’re giving the Best Product in the Hackaday Prize $30,000, and an opportunity to work in a lab filled with tools to turn that prototype into a marketable reality.

Last week, we announced the twenty finalists of the Hackaday Prize Best Product competition. There’s still a lot of work these hackers and tinkerers need to do before the final judging round, but until then we can start taking a look at what are already some …read more

Hackaday Prize Entry: Low Cost KVM

Posted on by

Back in the old days, when handing someone a DB serial cable when they asked for a DE serial cable would get you killed, KVM switchers were a thing. These devices were simple boxes with a few VGA ports, a few PS/2 ports, and a button or dial that allowed your input (keyboard and mouse) and output (video) to be used with multiple computers. Early KVMs were really just a big ‘ol rotary switch with far, far too many poles. Do you remember that PS/2 wasn’t able to be hot plugged? The designers of these KVMs never knew that. …read more

Pogo Pin Serial Adapter Thing

Posted on by

A few weeks ago, I was working on a small project of mine, and I faced a rather large problem. I had to program nearly five hundred badges in a week. I needed a small programming adapter that would allow me to stab a few pads on a badge with six pogo pins, press a button, and move onto the next badge.

While not true for all things in life, sometimes you need to trade quality for expediency. This is how I built a terrible but completely functional USB to serial adapter to program hundreds of badges in just a …read more

Superconference Interview: SpriteTM

Posted on by

SpriteTM, or [Jeroen Domburg], has a bit of a following around these parts. He’s installed Linux on a hard drive the hard way. He can play Snake on his keyboard. He’s cared for several generations of Tamagotchis. In short, there are very few people who have both the technical ability and sense of humor to pull off what [Sprite] does.

At last year’s Supercon, we pulled Sprite aside to talk about his work and his latest hack, the tiniest Game Boy ever. He talked about his Supercon keynote, and how to hack the crypto challenge in last year’s Superconference badge …read more

Friday Hack Chat: PCB Manufacturing

Posted on by

There’s a world of difference between building one of something and building multiples of something. The effort that goes into manufacturing does not scale linearly, and manufacturing is a skill in itself. This Friday, we’re going to be talking all about PCB manufacturing and assembly over on Hackaday.io

On deck for this Hack Chat will be [Jonathan Hirschman], the brains behind PCB:NG, a turnkey electronics manufacturing startup based around NYC. Jonathan is a self-taught hardware guy, proficient in PCB layout, 3D CAD, and manufacturing tech. PCB:NG is, essentially, taking oldskool manufacturing and making it into more of a digital process. …read more

These Twenty Wheels, Wings, and Walkers Won $1000 In The Hackaday Prize

Posted on by

Today, we’re excited to announce the winners of the Wheels, Wings, and Walkers portion of The Hackaday Prize. We were looking for the next generation of robots, drones, machines that make machines move, and hackers who now know far too much about inverse kinematics. The results were spectacular.

Hackaday is currently hosting the greatest hardware competition on Earth. We’re giving away thousands of dollars to hardware creators to build the next great thing. Last week, we wrapped up the third of five challenges. It was all about showing a design to Build Something That Matters. Hundreds entered and began …read more
