This Keyboard And Mouse Also Gives You A Workout

Posted on by

The Ergonomic Handheld Mouse / Keyboard Alternative from [Shervin Emami] is an all-in-one solution for your keyboarding and cursor moving needs.

The core of this build is a ‘grip-strengthening’ device that’s sold to guitarists. While the actual benefit of these devices for guitarists is questionable — there are a few anecdotes any music teacher will tell you about classical pianists ruining their hands with similar devices — the device itself can be converted into a fantastic chording keyboard. All you really need for a full-functioned keyboard is a few buttons in a rugged shell, and this ‘grip strengthener’ has that …read more

Join Hackaday For A Night Of Pre-Maker Faire Hacks

Posted on by

This weekend is the World Maker Faire in New York, and Hackaday will be there looking at the latest and greatest projects from makers around the globe. We’ll also be buying bottles of water for five dollars, but that’s another story entirely.

As always, this year’s World Maker Faire will be held at the wonderful New York Hall of Science, and the lineup is spectacular. There will be cosplay, and Adam Savage will be there with a half dozen Junior Mythbusters. There will be a twenty-six foot tall hydraulic hand trucked in from Burning Man. You’re looking at the greatest …read more

Ask Hackaday: How’s That Capacitor Shortage Going?

Posted on by

There is a looming spectre of doom hovering over the world of electronics manufacturing. It’s getting hard to find parts, and the parts you can find are expensive. No, it doesn’t have anything to with the tariffs enacted by the United States against Chinese goods this last summer. This is a problem that doesn’t have an easy scapegoat. This is a problem that strikes at the heart of any economic system. This is the capacitor and resistor shortage.

When we first reported on the possibility of a global shortage of chip capacitors and resistors, things were for the time being, …read more

A $1, Linux-Capable, Hand-Solderable Processor

Posted on by

Over on the EEVblog, someone noticed an interesting chip that’s been apparently flying under our radar for a while. This is an ARM processor capable of running Linux. It’s hand-solderable in a TQFP package, has a built-in Mali GPU, support for a touch panel, and has support for 512MB of DDR3. If you do it right, this will get you into the territory of a BeagleBone or a Raspberry Pi Zero, on a board that’s whatever form factor you can imagine. Here’s the best part: you can get this part for $1 USD in large-ish quantities. A cursory glance at …read more

Man’s Best Robotic Friend

Posted on by

When it comes to robotics, some of the most interesting work — and certainly the most hilarious — has come from Boston Dynamics, and their team of interns kicking robotic dogs over. It’s an impressive feat of engineering, and even if these robotic pack mules are far too loud for their intended use on the battlefield, it’s a great showcase of how cool a bunch of motors can actually be.

It’s not quite up there with the Boston Dynamics robots, but [Dimitris]’ project for the Hackaday Prize is an almost equally impressive assemblage of motors, 3D printed parts, SLAM processing …read more

The Desktop Computer Returns As Amiga-Infused Retro Case

Posted on by

The desktop computer is dead. No, I don’t mean computers that are meant to sit either on or underneath a desk. I’m talking about computer cases that are placed on a desk horizontally, probably with a monitor on top. The ‘monitor stand case’ was a mainstay for most of the 80s and 90s, but died out when CRTs became too heavy.

Now, though, there’s an interesting Kickstarter project that aims to bring the desktop computer case back, and it’s doing it as an upgrade to the classic Amiga 500, Amiga 1200, and Amiga 600 computers.

The idea for this project …read more

Hackaday Links: September 16, 2018

Posted on by

Apple released a phone, the most phone in the history of phones. It’s incredible.

There are four machines that are the cornerstone of electronic music. The TR-808, the TR-909, the TB-303, and the SH-101 are the machines that created techno, house, and every other genre of electronic music. This week at KnobCon Behringer, the brand famous for cheap mixers, other audio paraphernalia of questionable quality, and a clone of the Minimoog, teased their clone of the 909. Unlike the Roland reissue, this is a full-sized 909, much like Behringer’s clone of the 808. Price is said to be under $400, …read more

Turn Yourself Into A Cyborg With Neural Nets

Posted on by

If smartwatches and tiny Bluetooth earbuds are any indications, the future is with wearable electronics. This brings up a problem: developing wearable electronics isn’t as simple as building a device that’s meant to sit on a shelf. No, wearable electronics move, they stretch, people jump, kick, punch, and sweat. If you’re prototyping wearable electronics, it might be a good idea to build a Smart Internet of Things Wearable development board. That’s exactly what [Dave] did for his Hackaday Prize entry, and it’s really, really fantastic.

[Dave]’s BodiHub is an outgrowth of his entry into last year’s Hackaday Prize. While the …read more

The Tiny, Pocket-Sized Robot Meant For Hacking

Posted on by

The world is full of educational robots for STEAM education, but we haven’t seen one as small or as cute as the Skoobot, an entry in this year’s Hackaday Prize. It’s barely bigger than an inch cubed, but it’s still packed with motors, a battery, sensors, and a microcontroller powerful enough to become a pocket-sized sumo robot.

The hardware inside each Skoobot is small, but powerful. The main microcontroller is a Nordic nRF52832, giving this robot an ARM Cortex-M4F brain and Bluetooth. The sensors include a VL6180X time of flight sensor that has a range of about 100mm. Skoobot also …read more
