Micro Magician robot controller - I can finally tick the project complete box!

I started designing this controller in December 2011. After 4 months and 2 previous revisions it will finally be shipping out April 2012. I think this is DAGU's best Arduino compatible robot controller yet!

Designed for small robots using small batteries, the Micro Magician is a 3.3V controller running at 8MHz.
Working from 3.6V to 9V means this constroller can run from a single LiPo cell or 3x NiMh batteries.
Reverse polarity protection means no blue smoke if you get your power wires crossed (reverse polarity diode rated at 3A).

Projects Lately: Helmet, Printrbot, ...

I've been busy lately tinkering on and off and thought readers might be interested in what I've been working on.

I spent a few nights of spare time last week rebuilding my bluetooth ski helmet, which is now working perfectly with a new main board. It's a glove- and snow-friendly conversion of a Motorola S305, retaining nothing but the main PCB, with the earphones and mic broken out to 3.5mm jacks, all buttons broken out to .1" pin headers, a much bigger battery, and an Adafruit USB LiIon/LiPoly charger. I'll post a few pictures soon, and it will get a full shakedown this weekend at Alpine and/or Squaw.

I backed the Printrbot project on Kickstarter a few months ago and received the printed parts in the mail recently, so I've got the 3D printing bug. After raising over 33x of the target funding, its creator Brook Drumm is understandably busy getting promised kits out to other backers. That leaves a lot for me to get together, mainly the hardware, electronics, and hot end, but without an official BOM I'm picking through lots of incomplete lists and RepRap parts wikis. The mechanical design being so much simpler than a Prusa Mendel is what got me interested, and I'm happy working on it when time allows over the next few months. It could be Arduino-driven but that's still up in the air; Sanguinololu electronics are included in the complete kit, so I have a few Pololu A4988 stepper driver boards on the way to play around with.

I did use an Arduino (actually a Boarduino) a few weeks ago to build something for work, but as cool as it is, I can't discuss it here except to say that it's camera-related... of course :)

Insert Coin: Node helps your smartphone monitor pretty much everything

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.
Fallen out of love with sensor? Don't worry, Variable Technologies is here to help. The company's working to bring the world Node, a project aimed at helping smartphone users "explore the fun and power of sensors." The "Swiss Army knife-sized" modular device communicates with the iPhone 4S and Android devices via Bluetooth. It has a built-in accelerometer, magnetometer and gyroscope and can detect physical motion and space, temperature and elevation, to name but a few. It also has a game control module and eight LEDs that can double as a camera flash, with carbon monoxide and radiation detection on the way. The Node will be compatible with Arduino devices and will have an open API, firmware and source code. There's a month left to help Variable hit its lofty $50,000 goal.
