Modular Keyboards For CAD, Gaming, And Video Editing

Of all the input devices, the keyboard is the greatest. This comes at a cost, though: there were times back in the Before Days, when video and music editing applications came with custom keyboards. There were Pro Tools keyboards, Final Cut keyboards, and innumerable Adobe keyboards. What’s the solution to this problem? More keyboards, obviously, and this time we’ll make them modular.

For his Hackaday Prize entry, [Cole B] is building modular, programmable USB keyboards. It’s got everything: a standard 3×3 keypad, a keyboard that’s just four potentiometers, a keyboard that’s a rotary encoder, and a keyboard that’s a set …read more

Moving 3D Printed Prosthetic Arms With A Pulse

One of the best uses of 3D printers we’ve seen are custom prosthetics. Even today, custom-built prosthetics cost an arm and a leg, but there’s no reason why they should. Right now, we can scan someone’s arm or leg, import that scan into a 3D-modeling program, and design a custom-fit orthotic that can be spit out on a 3D printer. Now, we’re seeing some interesting methods of turning those 3D-printed parts into the beginnings of a cybernetic design. This is a custom printed robotic hand controlled by a pulse sensor. It’s in its early stages right now, but so far …read more

Count To F Easily With This DIY Calculator

Some of the greatest electronic calculators of all time, including the venerable HP-16C, included functionality to convert numbers between different bases. 3735928559 might not mean much in base 10, but convert that to hex, and you’ll offend vegetarians. If the great calculators of yore had a way to convert between number bases, that means someone must make a standalone device to do the same, right? That’s what [leumasyerrp] is doing for their entry into the Hackaday Prize, anyway.

The Base Convert project is a simple desktop calculator designed to convert between hexadecimal, decimal, and binary. To do this, there’s an …read more

Twenty Projects That Just Won the Human Computer Interface Challenge

The greatest hardware competition on the planet is going on right now. The Hackaday Prize is the Oscars of Open Hardware. It’s the Nobel Prize of building a thing. It’s the Fields Medal of firmware development, and simply making it to the finals grants you a knighthood in the upper echelon of hardware developers.

Last week, we wrapped up the fourth challenge in The Hackaday Prize, the Human Computer Interface challenge. Now we’re happy to announce twenty of those projects have been selected to move onto the final round and have been awarded a $1000 cash prize. Congratulations to the …read more

This Is Your Solution For Open Source Motion Tracking

The HTC Vive Tracker adds real-world objects to your virtual world. While these real-world objects in virtual environments are now mostly limited to a Nintendo Zapper for a Duck Hunt clone and a tennis racket, the future is clear: we’re going to be playing Duck Hunt and Wii Sports while wearing headsets. The future is so bright, it burns.

Of course, with any piece of neat computing hardware, there’s an opportunity for building an Open Source clone. That’s what [Drix] is doing with his Hackaday Prize entry. He’s created an Open Source Vive Tracker. It’s called the HiveTracker, and it …read more

The Quest For High Powered Blinky And Buzzing

Sometimes, we need devices to notify us of something. The oven timer is going off. Your phone has a push notification. The smoke detector battery is getting low. All of these problems can be solved with a buzzer or an LED. It’s a simple and cheap problem to solve.

But what if you need to know if something’s wrong with a diesel engine that throwing out 90 dB of noise? What if you’re not guaranteed to be around that engine? What if you need to tell everyone within a half mile that something is wrong. Again, LEDs and beepers, but …read more

You Have To Have A Very High IQ To Understand This Rick And Morty Portal Gun Replica

It’s barely September, but that still means you’ve got to start working on your Halloween costume. If last year is any indication, the most popular costume this year will be, by far, Rick from Rick and Morty. There’s a lot to be said about this, but let me simplify it: if you dress up as Rick from Rick and Morty, you are not a Rick. You’re a Morty.

Nevertheless, Halloween is an awesome opportunity for some cosplay and prop-making action, and [Daren] has this year all wrapped up. He’s building the portal gun from Rick and Morty, …read more

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

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

Optimizing Screen Time To Heart Beats

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

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
