‘SHE BON’ is an Artful, Wearable, Sensual, Sensing Platform

Posted on by

SHE BON (that’s the French bon, or “good”) is an ambitious project by [Sarah Petkus] that consists of a series of wearable electronic and mechanical elements which all come together as a system for a single purpose: to sense and indicate female arousal. As a proponent of increased discussion and openness around the topic of sexuality, [Sarah]’s goal is to take something hidden and turn it into something obvious and overt, while giving it a certain artful flair in the process.

The core of the system is a wearable backpack in the shape of a heart, from which all …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

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

Speech Recognition Without A Voice

Posted on by

The biggest change in Human Computer Interaction over the past few years is the rise of voice assistants. The Siris and Alexas are our HAL 9000s, and soon we’ll be using these assistants to open the garage door. They might just do it this time.

What would happen if you could talk to these voice assistants without saying a word? Would that be telepathy? That’s exactly what [Annie Ho] is doing with Cerebro Voice, a project in this year’s Hackaday Prize.

At its core, the idea behind Cerebro Voice is based on subvocal recognition, a technique that detects electrical signals …read more

Using Motors As Encoders

Posted on by

If you have a brushless motor, you have some magnets, a bunch of coils arranged in a circle, and theoretically, all the parts you need to build a rotary encoder. A lot of people have used brushless or stepper motors as rotary encoders, but they all seem to do it by using the motor as a generator and looking at the phases and voltages. For their Hackaday Prize project, [besenyeim] is doing it differently: they’re using motors as coupled inductors, and it looks like this is a viable way to turn a motor into an encoder.

The experimental setup for …read more

Video Quick Bit: The Best In Human Computer Interfaces

Posted on by

We’re neck deep in the Hackaday Prize, and we just wrapped up the Human Computer Interface Challenge. This is an incredible contest to go beyond traditional mice and keyboards to find new ways to transfer your desires directly into a computer. Majenta Strongheart is back at it again, giving us a look at some of the coolest Human Computer Interface builds in this year’s Hackaday Prize

The Hackaday Prize is all about hacking, really, and there’s no better project that demonstrates this than [Curt White]’s hacked fitness tracker. This is a tiny, $35 fitness tracker that’s loaded up with …read more

Disassembling Mouse Sensors For Tracking Tongues

Posted on by

We just wrapped up the Human Computer Interface challenge in this year’s Hackaday Prize, and with that comes a bevy of interesting new designs for mice and keyboards that push the envelope of what you think should be possible, using components that seem improbable. One of the best examples of this is The Bit, a project from [oneohm]. It’s a computer mouse, that uses a tiny little trackpad in ways you never thought possible. It’s a mouse that fits on your tongue.

The idea behind The Bit was to create an input device for people with limited use of their …read more

DIY Switches For People Who Can’t Push Switches

Posted on by

An outstanding number of things most people take for granted present enormous hurdles for people with physical disabilities, including interaction with computers and other digital resources. Assistive technologies such as adaptive switches allow users who cannot use conventional buttons or other input devices to interact with digital devices, and while there are commercial offerings there is still plenty of room for projects like [Cassio Batista]’s DIY Low-cost Assistive Technology Switches.

[Cassio]’s project focuses on non-contact switches, such as proximity and puff-based activations. These are economical, DIY options aimed at improving accessibility for people who are unable to physically push even …read more

Now, Finally, We Can Play With Power

Posted on by

In case you’re not a ’90s kid, the Nintendo Power Glove is the greatest device for human-computer interaction ever created. It’s so good, they called it bad, and then they made a movie about it. At its heart, the Power Glove is just some force sensors in the fingers of a glove, but that hasn’t stopped hackers from cracking these gloves open for years. We’ve seen the Power Glove used in Hackaday Prize entries before, we’ve seen it control quadcopters, we’ve seen it used as a Vive controller, and the Ultimate Power Glove comes loaded up with Bluetooth, motion …read more
