Towards Open Biomedical Imaging

Posted on by

We live in a world where anyone can build a CT machine. Yes, anyone. It’s made of laser-cut plywood and it looks like a Stargate. Anyone can build an MRI machine. Of course, these machines aren’t really good enough for medical diagnosis, or good enough to image anything that’s alive for that matter. This project for the Hackaday Prize is something else, though. It’s biomedical imaging put into a package that is just good enough to image your lungs while they’re still in your body.

The idea behind Spectra is to attach two electrodes to the body (a chest cavity, …read more

Challenge Your Perception Of Reality With Emotional Sunglasses

Posted on by

The Peril-Sensitive sunglasses of Hitchhiker’s Guide fame directly affect the user’s response to a stimulus, turning completely opaque in response to danger. That’s a great idea, but what if sunglasses could affect your emotions? That’s what the EmotiGlass project in this year’s Hackaday Prize is doing. It’s a concept that allows a computer to change the user’s emotional perception of reality.

The key idea behind the EmotiGlass comes from a paper published by a researcher at the University of London just this year. Apparently, your emotional reaction to an image can be controlled depending on the point in time during …read more

This Is Your Last Chance To Enter The Hackaday Prize

Posted on by

For the last seven months, we’ve been running the world’s greatest hardware competition. The Hackaday Prize is the Academy Awards of Open Hardware, and a competition where thousands of hardware hackers compete to build a better future. The results have already been phenomenal, but all good things must come to an end: we’re wrapping up the last challenge in the Hackaday Prize, after which the finalists of the five rounds will move on, with the ultimate winner being announced next month at the Hackaday Superconference.

We’re in the final hours of the Musical Instrument Challenge, where we’re asking everyone to …read more

SENSEation Shows The Importance of Good Physical Design

Posted on by

Sensor network projects often focus primarily on electronic design elements, such as architecture and wireless transmission methods for sensors and gateways. Equally important, however, are physical and practical design elements such as installation, usability, and maintainability. The SENSEation project by [Mario Frei] is a sensor network intended for use indoors in a variety of buildings, and it showcases the deep importance of physical design elements in order to create hardware that is easy to install, easy to maintain, and effective. The project logs have an excellent overview of past versions and an analysis of what worked well, and where they …read more

The Magic Flute of Rat Mind Control Aims to Mix Magic and Science

Posted on by

Well this is unusual. Behold the Magic Flute of Rat Mind Control, and as a project it is all about altering the response to the instrument, rather than being about hacking the musical instrument itself. It’s [Kurt White]’s entry to the Musical Instrument Challenge portion of The Hackaday Prize, and it’s as intriguing as it is different.

[Kurt] has created a portable, internet-connected, automated food dispenser with a live streaming video feed and the ability to play recorded sounds. That device (named Nicodemus) is used as a Skinner Box to train rats — anywhere rats may be found — …read more

An Unmanned Ground Vehicle, Compatable With An Arduino

Posted on by

Building your own robot is something everyone should do, and [Ahmed] has already built a few robots designed to be driven around indoors. An indoor robot is easy, though: you have flat surfaces to roll around on, and the worst-case scenario you have a staircase to worry about. An outdoor robot is something else entirely, which makes this project so spectacular. It’s the M1 Rover, an unmanned ground vehicle, built around the Arduino platform.

The design goal of the M1 Rover isn’t just to be a remote-controlled car that can be driven around indoors. This robot is meant for rough …read more

The Leap Motion Makes Robots Bend To Your Will

Posted on by

We just wrapped up the Human Computer Interface challenge in this year’s Hackaday Prize, and this project is pushing boundaries we’ve hardly seen before. [Giovanni Leal] is using a Leap Motion controller to move a robotic arm around in space.

The robot arm in question comes from Owi, and it is by every measure not a good robot arm. It is, however, an excellent toy filled with motors and plastic linkages that serves as a good stand-in for a proper robotic arm.

Control of this toy robot arm is done through a Leap Motion controller. While the Leap Motion is …read more

Tindie Guides That Hackaday Prize Entry Into Your Hands

Posted on by

The Hackaday Prize invites everyone to focus on specific challenges with encouragement of prize money and motivation of deadlines. But what happens after the award ceremony? While some creators are happy just to share their ideas, many projects need to get into the real world to make their full impact. Several past prize winners have used their award as seed money to start production and go into business. Recognizing this as something worth supporting, a new addition this year is Tindie’s Project to Product program.

Tindie is a marketplace for makers to sell to other makers, hence a natural place …read more

Gesture Control without Fancy Sensors, Just Pots and Weights

Posted on by

[Dennis] aims to make robotic control a more intuitive affair by ditching joysticks and buttons, and using wireless gesture controls in their place. What’s curious is that there isn’t an accelerometer or gyro anywhere to be seen in his Palm Power! project.

The gesture sensing consists not of a fancy IMU, but of two potentiometers (one for each axis) with offset weights attached to the shafts. When the hand tilts, the weights turn the shafts of the pots, and the resulting readings are turned into motion commands and sent over Bluetooth. The design certainly has a what-you-see-is-what-you-get aspect to it, …read more

Give Yourself A Sixth Sense With An Arduino

Posted on by

If you carry a smartphone around in your pocket, you have a GPS navigation system, a compass, an altimeter, and a very powerful computer at your fingertips. It’s the greatest navigational device ever created. To use this sextant of the modern era you’ve got to look down at a screen. You need to carry a phone around with you. It’s just not natural.

For this entry into the Hackaday Prize, [Vojtech Pavlovsky] has an innovative solution to direction finding that will give you a sixth sense. It’s a headband that turns your temples into the input for a clever way …read more
