littleBits Arduino with Extra I/O HeadersIn keeping in line with their KISS philosophy, the littleBits Arduino module does not offer (easy) access to the full range of analog and digital I/O options that can be found on regular Arduino boards like the Arduino Uno. As a matter of fact, the littleBits Arduino only provides 3 bitSnap inputs and 3 bitSnap outputs if you intend on staying entirely within the littleBits ecosystem. Another difference is that unlike regular Arduino boards, the littleBits version uses its micro USB port for programming only. Power for the module must be supplied via one of the bitSnap inputs.

If you want to use your own sensors or actuators and you don’t have a Perf Module or Proto Module, or if the bitSnap inputs (or outputs as the case may be) are all full, hope is not lost. littleBits recognized that many users would need more I/O and all it takes is a little bit (no pun intended) of soldering.

ROBOTIS Bioloid modular robot kit

I’m finally getting through posting about the robots at IREX last week, but the one that is left on my list, the ROBOTIS Bioloid robot kit, may be of the most interest to amateur roboticists. There are several robot kits available these days, and they run the gamut from relatively simple and cheap to expensive and complicated. On the more affordable end of the spectrum are Lego Mindstorms and Radio Shack’s VEX system. More expensive (and complex) products include Kondo’s KHR-1. Korean manufacturer ROBOTIS offers systems similar to the KHR-1 in that they can be purchased in a kit form that includes a microcontroller, servos, sensors, frames, and wheels. Unlike the KHR-1 each kit can be assembled into a variety of different forms including a humanoid, dog, spider, or whatever you can imagine. If you need additional components to create your custom bot, ROBOTIS sells all of the parts individually as well. The Bioloid kit sells for $1500 USD.

The Kegbot

credit: M. Wakerly

Popular Science has an article today about the Kegbot, a keg fridge crossed with a Linux computer. Developed by software engineer Mike Wakerly, the system is built around a microcontroller that manages a valve and flowmeter that’s been integrated into the tap line of an ordinary keg fridge. The controller is interfaced to a Linux computer and software developed by Wakerly that manages user access, tracks pour totals and keg performance statistics, and publishes it all online.
