Who knew Lego characters had to be somewhere in a hurry? Adafruit did, as it just whipped up a minifig-sized train schedule. The invention mates one of Adafruit's own 1-inch OLED boards with an Arduino Uno controlling the schedule behind the scenes. It looks to be a straightforward project for the DIY types, although the display is currently all show: the schedule doesn't (yet) pair up with the train tracks to automatically let your minifigs know if their trip to the pirate spaceship castle has been delayed by ghosts. You can check the source link for the full instructions. Duplo builders, alas, are kept out of the loop.

Fijibot is an autonomous, self-charging photovore. I built him using a 1.5 liter Fiji Water bottle, an Arduino Uno, 6v solar panel (plus various other parts) from Radio Shack, an Arduino Proto Shield (plus various other parts) from Adafruit, and the wheels and steering arrangement from an RC car.

Ben Heck is always thinking up gadgets that make life easier, from completely hands-free luggage to a sensor system for improved cycling safety. His latest mod is meant for those of us who have burnt Ramen a few too many times. His so-called Ben-Stur Remote Control Android app works with a pot-stirring device, freeing users to stray from the kitchen while their meal is cooking. The app works via Bluetooth, and the pot-stirrer consists of an actuator arm, a chip clip, a timing belt and, of course, a wooden spoon. Heck used a Google ADK and an Arduino Uno for the control mechanism that communicates between the app and the stirrer. In the tablet app, users can check their food's temperature and control the speed of the the spoon's stirring. If that whets your appetite, click the source link for more info -- and check out our Maker Faire interview with Mr. Heckendorn himself.

Welcome to IRL, an ongoing feature where we talk about the gadgets, apps and toys we're using in real life and take a second look at products that already got the formal review treatment.

Welcome back to IRL, and if we do say so ourselves, this week's edition is a doozy. On one end of the gadget-loving spectrum, Jason is still happily using his Canon Rebel XT, while Darren remains thoroughly unsatisfied with his $400 AirPlay speaker (it was easy to set up, at least -- he'll give it that). And, just for good measure, we threw in an Arduino fail. So, which piece of audio gear is on our "do not buy" list? Who needs to take a course in wiring-based coding? And does Jason have anything negative to say about his DSLR? Head past the break to find out.

"SpiDuino" because of course it's Arduino for brains, and if you watch the end of the video it tries to climb up the wall.  Gets about to 90 degrees, too.  This is a variation on the "Start Here" robot that this site is famous for.  Essentially I wanted to test the base and the SN754410, which I was having trouble with and noted in this node.  Obviously I got it going, but special thanks to ChrisTheCarpenter and Kyle (birdmun) for their guidance.

I had bought a RC Car from walmart for about $15 to use with the Arduino Motorshield a while back (see here). Fortunately, I had taken some pictures before I removed the RC receiver circuit from it. Turns out that its lot more efficient to use the onboard controller along with an Arduino instead of using a motorshield. I didnt some research and found out that many “cheap” RC cars use the same Realtek TX2 & RX2 chips inside. I was lucky enough to find the same inside this RC car.
