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.

Humane Reader $20 information repository targets the destitute & disconnected

Humane Reader $20 information repository targets the destitute & disconnected

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]

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

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.

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]

Twitwee Clock replaces cuckoo with Twitter bird [Video]

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").

Arduino Nano 3.0 slims down for compact breadboarding

Arduino Nano 3.0 slims down for compact breadboarding

Tinkerers, DIY-nuts and electronic manglers, hold onto your hats: there's a new Arduino in town.  Everybody's favorite prototyping board has just gained a new family member, in the shape of the Arduino Nano 3.0.  It drops the size down to just 1.7 x 0.7 inches while still packing integrated mini-USB, top-mounted LEDs and ATMEGA328, and in fact the only thing you're really doing without is the power jack.
