Arduino-Based Geiger Counter

, Apr 15th 2011 Discuss [1]

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're going to die a slow painful death from radiation poisoning. It's not a very fun device. Actually, they're pretty awesome. Who doesn't want to be able to play with a gadget that can sense things that only manifest in humans as genetic decay?

Robot claw delta-robot controlled by Kinect and Arduino

, Mar 8th 2011 Discuss [0]

One time my daughter and I were in the local grocery store and she wanted to play that game where you use the claw to pick up stuffed animals. Somehow, the stars aligned and I ended up winning two stuffed animals for her and now she thinks I can win at will, which isn't accurate at all. Some geeks have developed an interesting new robot for a project in college that reminds me of that game machine at the store. Read The Full Story

DIY Exploding High-Five Glove makes hand-slapping geeky [Video]

, Dec 22nd 2010 Discuss [2]

As we all know, high-fiving went out of fashion because it wasn't loud enough; kids experimented with gunpowder and methane gas, but it all proved far too unstable. Happily Eli Skipp has stepped in with her DIY "exploding high-five glove": it doesn't actually explode, just use an Arduino, a force-sensor and a loudspeaker to make explosion noises whenever you high-five someone.

HALO DIY obstacle-avoidance system is low-cost radar for visually-impaired [Video]

, Dec 13th 2010 Discuss [0]

Haptics has come to mean the lackluster vibration your phone gives off when you use the on-screen keyboard, but there's plenty more potential for the technology. Steve Struebing has come up with HALO - Haptic Assisted Location of Obstacles - a headband intended to allow blind or visually-impaired users the ability to navigate without bumping into things.

NASA Droidrover project uses Android remote control [Video]

, Sep 29th 2010 Discuss [1]

Is there anything a humble Nexus One can't do?  Well, yes, probably - its track record at damson picking is pretty poor - but the Android smartphone has found favor over at the NASA Ames research labs where they're using it to remotely-control a Senseta rover as part of their Droidrover project.  According to the team there, the Nexus One - paired over Bluetooth with an Arduino - makes for a smaller, lighter and cheaper setup than their existing microcontroller and router, and that adds up to a rover with reduced power consumption, better performance and improved manoeuvrability.

DIY Secret Knock Detector lock is best use for Steampunk mechanical iris [Video]

, Aug 3rd 2010 Discuss [2]

Regular garage door openers are dull; why aren't you using a knock-controlled mechanical iris to authenticate visitors instead?  BFarn has been detailing his beautiful secret-knock detecting door project, which hides a tap-sensitive panel behind a huge Steakpunk-styled iris.

Humane Reader $20 information repository targets the destitute & disconnected

, Jul 19th 2010 Discuss [1]

Remember the so-called "$10 laptop" project the Indian government was spearheading early last year, that turned out to be a basic standalone storage brick?  Something similar this way comes, in the shape of the Humane Reader: a low-cost 8-bit display device that uses your TV as a display and cheap PS/2 peripherals, it can store around five thousand texts - including local Wikipedia mirrors - but costs just $20.

Korg Monotron meets iPad iElectribe & Wii Nunchuk for music mangling [Video]

, Jun 3rd 2010 Discuss [0]

Take a Korg Monotron analog synth, throw in an iPad running Korg's excellent iElectribe app and then use an Arduino to tie the whole thing together: you're not only hitting some of the geekiest keywords around these days, but getting an awesome, glitchy, electronic music mangling setup.  YouTuber Denkitribe has been circuit bending his Monotron, coming up not only with the system described above, but one in which the accelerometer and joystick of a Wii Nunchuk are used to control the battery-powered synth.

DIY iPhone-controlled four-stage coil gun [Video]

, May 17th 2010 Discuss [0]

What could be better than a DIY four stage coil gun capable of punching some serious holes in cardboard boxes?  How about mounting said-gun on a WiFi-controlled motorized turret, with a custom iPhone/iPad remote interface with live video streaming?  That's just what University of Arkansas engineering students Chris Farnell and Michael Helms put together.

DIY automatic ball balancing machine [Video]

, Apr 28th 2010 Discuss [2]

Forget your Newton's Cradle or that squeezy stress toy; this might just be the best executive desk toy so far.  The handiwork of 0zimbra0, this simple square of wood is - thanks to a couple of servos, a webcam and our old friend the Arduino - capable of keeping a ball bearing either balanced or following continually moving patterns.

Twitwee Clock replaces cuckoo with Twitter bird [Video]

, Apr 21st 2010 Discuss [0]

We're quite fond of bizarre gadgets that hook into Twitter, whether they be tweeting tables, monomes or robot fish, and so we're quite surprised that it's taken someone so long to use the blue Twitter bird logo in a tweeting cuckoo clock.  Happily Haroon Baig has filled that gap with his Twitwee Clock, a modified clock that replaces the traditional face with a set of chumby guts and keeps track of Twitter for a preset word, hashtag or username (in this case "TwitweeClock").

DIY Racing Hardware Sim gets hacked BMW instruments [Video]

, Apr 2nd 2010 Discuss [0]

Multi-screen PC gaming setups have made racing simulators all the more engrossing, but nothing says "realism" like real parts hacked from a car and hooked up via USB.  Alex Rosiu has kicked off his DIY Racing Hardware Sim with the instrument cluster from a 1992 BMW 325i, using an Arduino to control the speedo and rev counter along with the various lights.
