MIT student races self-built Mario-Kart

May 18, 2012



A bit of fun for a Friday afternoon... Ever found time passing heavy at work? Fancy spicing things up a gear? Maybe, racing round the corridors on your castor-based chairs? (No chance the boss will see you, he's away on a golfing trip...)

Well, it seems one MIT student found himself in this position, but also raised the stakes, putting his engineering prowess to the test to build a replica Mario-Kart, for aforesaid corridor racing...

Makey Makey circuit board turns objects into computer keys

May 15, 2012

Makey Makey.jpgThis is a nice one to share with Gadget Masters, from our sister site New Scientist - DIY circuit turns your alphabet soup into a keyboard

Jacob Aron writes about some wizardry from MIT:
Ever wanted to move Pac-Man using pencil drawings, make music with bananas or type an email with alphabet soup? Now you can thanks to Makey Makey, a simple circuit board that turns almost any object into a computer key (see video here).

"It works with anything that is a little bit electrically conductive," says Eric Rosenbaum, a researcher at the Massachusetts Institute of Technology. "Things like food, Play-Doh and lots of different metallic or organic materials."

Breathing on the IOIO board for an Android Breathalyser

May 11, 2012

Android breathalyser.jpgHere's a nice example of what you can do with the IOIO Android-friendly breakout board that we've featured previously.

It's a DIY Android Breathalyser. It's still in prototype form, but is shown working in cable-less form, courtesy of Bluetooth.

Note you would need a phone with Android 2.3.3+ ("Gingerbread") - for the requisite Bluetooth support - or else old-fashioned USB cable connectivity will be required...

The Kindle Touch competition

May 8, 2012

Kindle Touch prize.jpgIt's time for another Gadget Master competition! The theme we are taking for this one is the recent Mindstorms roundup, but the prize is not Lego-based! Time for a more conventional consumer electronics gadget, I feel...

Step forward the Kindle Touch, as a prize kindly provided by Gadget Master sponsor RS. With a touchscreen, audio and built-in Wi-Fi, the Touch version of Amazon's popular e-book reader would set you back £109.

MIT student builds mobile phone from parts

May 7, 2012

diy-cellphone-18WEB.jpgDavid Mellis, a PhD student at MIT has published the circuit and case designs and the source code for a working mobile phone that he built using parts worth
$1 50 (£93). The body is laser-cut from veneered plywood, and it has a 160x128pixel TFT screen

Whipping up a (programmable Lego) Mindstorm

lego mindstorms nxt.jpgBefore we launch the imminent May/June 2012 compo, let's have another themed roundup of posts... on Mindstorms ("Lego sets combining programmable bricks with electric motors, sensors, Lego bricks, and Lego Technic pieces (such as gears, axles, and beams)", as Wikipedia once put it).

Mindstorms has its historic roots, apparently, in a programmable brick created at the MIT Media Lab...

Anyway, the plastic brick-based platform has long proved fertile ground for Gadget Masters, so there are quite a few Lego-related posts to choose from...

Spider silk conducts heat as efficiently as metals

May 4, 2012

spiderman_3_movie_image-WEB.jpgA post about spider silk might sound more like biology than electronics; and the strength of spider webs is the stuff of legend, as Spiderman fans will tell you. But recent research at Iowa State University by Xinwei Wang has raised some issues that might mean we need to rethink the pigeonholing.

polyphonic-theremin.jpgMay - and the season of Bank Holidays - is upon us! But before April 2012 becomes but a distant memory let's tarry just a while to consider the most popular posts on the blog in the foregoing month.

Topics covered include: Geiger counters, Android and NFC, calculator pranks and Flea robots... 

Taking it in reverse order, for maximum suspense:

Cardboard camera

April 30, 2012

The whole thing is neat - even the USB connector.

Lego Mindstorms robot learns to play Rock-Paper-Scissors

April 25, 2012

rock scissor paper robot.jpgWhen Robots take over the world, will they play Rock-Paper-Scissors to pass the time? Well, one of their precursors does (featured at Robogames 2011 for the Lego Open challenge, where it won first place).

A canny inventor has constructed a Lego Mindstorms NXT-based device to play the game. That is to say, it learns how to play the game from past experiences. And it won't just learn to take part (apparently simulating a simple neural network), it will "beat a person 100% of the time!" the creator boasts.

Stanford students && (Android + NFC + TV) == Fun

April 11, 2012

Stanford MobiSocial.jpgStanford students are demonstrating the potential of NFC-based hackery with a number of projects "showing how NFC-equipped phones and televisions can work together". Very impressive it is, too.

The five applications - running between their NFC-linked Android phones and a TV - include:
* displaying photos in a slide show
* rigging up a collaborative whiteboard
* sharing a slide show presention
* playing a game of online poker and
* streaming Netlix videos...

Apparently, the TV components are done in Javascript and HTML, and the Android apps were written in Java, as is standard for Google's mobile platform.
