The Hacker Village Of Supercon

November 16, 2017 by 9 Comments

I’m utterly exhausted and still in a state of awe. The Hackaday Superconference has grown in so many ways, but one thing remains the same: the spirit of the Hacker Village — an intangible feeling that grows up around all who attend — is bliss to take part in.

There’s really no substitute for having been there in person. I’ll go into detail below and try to share the experience as best I can. But the gist of the atmosphere is this: everyone at Supercon is the type of person you’d want to be stuck in a rowboat with, or partnered with on an engineering project, or to have next to you while trying to save the world. There are no looky-loos at Supercon. It turns out we are all stuck in a rowboat together, we are all working on engineering projects, and we are all trying to save the world. And when we all get together it feels like a drug our pragmatic minds never knew existed. This is the recharge for that sense of urgency that keeps you going all year long.

So yes, you really missed it. But start now. Become friends with all of these people over the next year. Begin building your Supercon community now and it’ll feel like a reunion when it rolls around again next November.

Your Drone Is Cool, But It’s No Jet Fighter

November 16, 2017 by 45 Comments

There are some communities with whom our happy band of hardware hackers share a lot in common, but with whom we don’t often associate. The more workshop-orientated end of the car modification or railway modeler scenes, for instance, or the model aircraft fraternity. Many of these communities exist more for the activity than for the making, some of them dabble with building kits, but among them are a hard core of people who create amazing projects from scratch.

Take [Igor Negoda], for example. Not content with building just any model aircraft, he’s built his own from scratch, to his own design. And if designing for yourself what amounts to a scaled-down jet fighter wasn’t enough, he’s also built his own jet engine to power it. His videos are all in Russian so use YouTube’s subtitle feature if you’re not a Russian speaker, but they’re so good that if you couldn’t access the English translation you’d want to learn the language just to hear his commentary.

The video below the break shows us first a fast-taxi test using a ducted fan, then a full test flight with the jet engine. There is an explanation of the fuel system and the flight control systems, before an impressive flight from what appears to be a former Cold War-era runway. There are a few funny moments such as transporting a large model jet aircraft in a small hatchback car, but the quality of the work in a garage workshop shines through. Suddenly a multirotor doesn’t cut it any more, we want a jet aircraft like [Igor]’s!

Hacking An Industrial 42″ Multitouch PC

November 16, 2017 by 51 Comments

We’re slowly moving in the direction where everyone will have a touch screen desk like in the 1982 TRON movie or in the 1987 Star Trek: The Next Generation series with its ubiquitous touchscreen starship controls. [FFcossag] lucked into that future when a local company offered him an industrial 42″ multitouch PC that they were throwing out. A few hacks later and he has us all suitably envious.

Before hacking away though, he had to take care of some magic smoke. The source of this turned out to be yellow goop on the PC’s power supply that had turned conductive across a resistor. Cleaning it fixed the problem.

Moving on to the hacks, he added brightness control by using a potentiometer to control the power to the backlight. Be sure to watch carefully in the video below where he’s attaching a magnet and cord to the potentiometer, and encasing it all in epoxy. At that point, we’re pretty sure we see him spin up a hard drive platter with a sandpaper disk attached to it, forming a bench top disc sander and making us like this hack even more.

He also replaced a small speaker with a larger speaker and amplifier, giving a volume and sound quality difference that’s like night and day. He also added a breakout board with relays for power management, eliminating a seven watt continuous draw when in standby mode.

Be sure to watch the video to the end where he leaves us with a tour of the hacked interior hardware. We like how he’s labeled all his handiwork for any future hacker who might open it up
