You’ll Be Shocked At This Way To Improve Your Video Game High Score

Posted on by

What if you could play video games perfectly? Would you be one of the greats, raking in millions of dollars simply by playing competitive Fortnite? That’s what Twitch does. Twitch plays video games for you. The irony of this name should not be lost on you.

For his Hackaday Prize entry, [Peter] built a device that shocks you into playing a computer game perfectly. These experiments began with a transcutaneous electrical nerve stimulator (TENS), or basically a device that makes you… twitch. This device, however, is connected to four buttons, representing up, down, left, and right. This is a video …read more

Salvaging an Ancient, Dangerous Machine With Wood

Posted on by

What do you do when you have a gigantic old drum sander with a bent table? Scrapping it will give you a few cents per pound, but this machine is just too cool, and would be too useful to just throw away. That’s when inspiration strikes. To fix this old machine, [Frank Howarth] built a new bed for an old drum sander out of wood.

The machine in question is a Frank H. Clement Surface Sanding Machine from the early part of the 20th century. This machine is basically a 30 inch long, 14 inch diameter drum that’s wrapped in …read more

Optimizing Screen Time To Heart Beats

Posted on by

Kids spend too much time in front of a screen these days. They also won’t get off my lawn, and music today is just a bunch of static. They don’t respect their elders, either. While kids today are terrible, we can fix that first problem — sitting in front of a screen all day. For his Hackaday Prize entry, [Donovan] has created a device that optimizes screen time to reduce sensory overload. It’s the Optimote, the combination of a remote control and biofeedback.

The idea behind the Optimote is to actually to reduce stimulation when watching something on a screen. …read more

Turning A Fitness Tracker Into An EEG

Posted on by

Several years ago, a company called Neurosky came out with an interesting chipset meant to be put in an EEG headset. This chipset would track your brainwaves, do some fancy math, and output a few numbers based on the Delta, Gamma, Alpha, and Beta waves in your brain. Of course, the senseable thing to do with this technology would be to put it in a Star Wars-branded toy where you pretend to be a Jedi. All was good with the world, and a few people hacked these Jedi Mind Trainers for some interesting builds.

But the Neurosky chip was still …read more

Competitive Soldering is Now a Thing

Posted on by

At Hackaday, we’re constantly impressed by the skill and technique that goes into soldering up some homebrew creations. We’re not just talking about hand-soldering 80-pin QFNs without a stencil, either: there are people building charlieplexed LED arrays out of bare copper wire, and using Kynar wire for mechanical stability. There are some very, very talented people out there, and they all work in the medium of wire, heat, and flux.

At this year’s DEF CON, we opened the floodgates to competitive soldering. Along with [Bunny] from Hardware Hacking Village and the many volunteers from the HHV and Soldering Skills Village, …read more

This Is The Raspberry Pi Robot To Beat All Others

Posted on by

Before the introduction of the Raspberry Pi, building robots was hard. The best solution to turning motors on a chassis was repurposing an old roomba. For the brain, maybe you could throw Linux on a router and move your rover around with an old Linksys. Before that, you could buy a crappy robotics kit, thrown together in a box and sold as an ‘educational kit’. I’m sure there are a few readers out there that built robots by wire-wrapping HC11s.

Now we have 3D printers and Raspberry Pis, and with that comes a golden age of robotics. One of …read more

Friday Hack Chat: GNU Radio

Posted on by

Software defined radio picked up a lot of popularity when it was discovered that cheap USB TV tuners were functional bits of hardware that could become SDRs. It’s the software that makes this possible, and when it comes to SDR software, there’s no better tool than GNU Radio. For this week’s Hack Chat we’re going to sit down with some of the people behind this awesome software tool and pick their brains.

Our guests for this week’s Hack Chat will be Derek Kozel and Nate Temple, officers of the GNU Radio project. They’re also organizers of this year’s GNU Radio …read more

The Largest Aircraft Ever Built Will Soon Launch Rockets To Space

Posted on by

Deep in the mojave, the largest aircraft ever made will soon be making test flights. This is the Stratolaunch, and it’s measured the largest to ever fly based on wingspan. The Stratolaunch was constructed out of two 747s, and is designed for a single purpose: as a mobile launch platform for orbital rockets.

There are a couple of ways to measure the size of an aircraft. The AN-225 Mriya has the highest payload capacity, but only one of those was ever built (though that might change soon). The Spruce Goose was formerly the largest aircraft by wingspan, but it only …read more

The Solution To Oversized Dev Boards: A Literal Hack

Posted on by

Oh, there was a time when you could prototype just about everything on a breadboard. The CPU in your computer came in a DIP package, and there were no BGA packages. to be found anywhere. In the forty years since then, chips have gotten smaller, packages have gotten more cramped, and you can barely hand-solder the coolest chips anymore. No worries — companies are still spitting out dev boards with 0.1″ headers, but there’s a problem: they don’t fit on a solderless breadboard. They’re too wide. Our world is falling apart.

[Luc] had a problem when he was playing with …read more

The Best New Quad Is A Bicopter

Posted on by

RCExplorer, or [David], or just ‘The Swede’, has come up with a bicopter kit. Yes, there are a lot of people making frames and kits for quadcopter, multicopters, drones, and so forth, but [David] is really the leader in weird multicopters. Now, we have the weirdest multicopter imaginable as a kit, complete with firmware that works.

[David] is one of the great unsung heroes of the drone and multicopter world. He’s famous for rocket knives, even though that really doesn’t have anything to do with drones, he bought an airplane for his front yard (again, little to do with drones), …read more
