In the Maker Shed: Arduino Mega now shipping
The Arduino Mega in the Maker Shed is the latest micro-controller from the Arduino team. The Mega is built around the ATmega1280. It's perfect for anyone looking for more room for code or to be able to control a lot more LEDs, sensors, servos, or motors. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs. Another great feature is the Arduino Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

Arduino HVAC servo thermostat
Instructables user tikka308 writes:
Because HVAC units use a lot of energy (particularly when in 'air conditioning' mode during hot summer months) and renters do not have the ability to easily implement energy star (i.e. more efficient) units or to regulate their tempature, I wanted to find a way, without making permanent changes, to control an HVAC unit like a thermostat! Implementing this device can not only save you money, but can help maintain a more steady-temperature in your apartment, reduce energy consumption and help reduce the strain placed on our nations power grid during the hot summer months!

Sparkfun Autonomous Vehicle Competition
Sixteen teams gathered today to determine whose autonomously-navigating vehicle would be the fastest around the Sparkfun headquarters in Boulder, CO.
Four-wheeled rovers (typically built on RC car platforms) dominated the entries, but there were three flying UAVs, and one spheroid (Nathan, with "labrat", pictured at right). One team had been designed a tethered model rocket to fly the course, but, unfortunately, didn't compete.
The race was structured as 3 heats. Each vehicle got 5 minutes to attempt a run; best time overall won the competition.
The first heat got off to a rough start. Only about half of the robots made it to the first corner of the building, and only the Mookie Mobile Death Pod 3000 made it around the whole course.
A slight wind from the West seemed to be affecting the DIY Drones's ability to precisely line up with the course route. It completed many test runs very well, but its first two official runs were disqualified for slightly cutting the corner of the course. The plane also found itself in multiple trees. The Boulder Fire Department was kind enough to help out with one, and other was low enough to get by hand.
The ground-based vehicles had other obstacles to deal with, including curbs, and people who foolishly think that curbs are a safe place to stand.
After nearly hitting its creator, Ohcraptheresalake! (who later went on to discover the creek) goes after innocent bystanders:
Entrants used the time between heats to tweak their robots according to the lessons learned from the previous run. Death Pod 3000, the only robot to complete the course in the first heat, solidified its lead in the second by lowering its time to 1:28.
In the end, though, the DIY Drones team scored a stunning success with their final try, with Chris Anderson's UAV completing the course in 36 seconds to win the tile!
The competition is over! Diy drones is 1st, with deathpod3000 taking the Engineers Choice award. Thanks for following!!! See you next year!

Getting Started with Arduino (and a bunch more O'Reilly books) on the iPhone
Andrew Savikas just showed me how to buy and read O'Reilly books on an iPhone or iPod touch. I was thrilled to see that Getting Started with Arduino was available. It looks great. And the book doesn't require any soldering, so you can (mostly) safely leave your iPhone on your workbench as you try out the projects.
Andrew's written up some helpful instructions for anyone who wants to give this a go (and all titles are 40% off for a limited time):

Dragon-bot fights fire with wind
Gareth used Arduino + MotorShield to create Puff - the Magical Firefighting Dragon!
Puff is able to Put out Fires - He Scans his Head to find the Flames - he orientates towards the Flame - and Blows it out.The bot uses 2 LDRs for flame tracking, plus infrared sensor for avoiding falls/collisions. (He also sports a nifty pair of glasses in the test videos. See more on the project page. [via adafruit industries]If he fails to blow out the Fire within 2 sweeps then the "PANIC" mode switches in and he backs away to save himself from frying his "Chips".
Puff is an Arduino based tracked autonomus Robotic Vehicle with "Cliff" and "Obstacle" detection.

Arduino kid's toy prototype
Kirsten Halterman writes in:
"My First Robot" is a book for young children (ages 1-3), intended as an introduction to sensory input and output. I created this book to excite children about small electronics and robots.
Using an Arduino, buttons, and an IR sensor, I programmed the robot (named Isbot) to sing a song for its user. When the user gives Isbot a high-five or a low-five (pushes one of the red buttons), Isbot detects their depth (Isbot's eyes are the IR sensor) and will either sing a song slowly (if they are close) or very quickly (if they are far away). This book gives parents a platform to discuss depth, sound, and touch.

Wireless inertial data glove using Arduino/Processing
Noah Zerkin sent us a vid to his current project. It's a wireless inertial data glove rig, built with an Arduino- and Processing-based motion capture system for use in creative interaction, augmented reality (AR), virtual reality (VR), etc. It's built entirely with parts from Sparkfun and RadioShack. He writes:
The thing that makes this special is how insanely inexpensive it was to build. The ultimate aim is to create a low-cost modular full-body interaction capture system for use in gaming, AR, and creative applications. The first commercial app I'm targeting for integration is Maya. After that, we'll look at integration with a game engine. I'm not sure what a glove/arm kit will cost, but it should be under $250 (Perhaps well under... we'll see... there are costs besides parts). Mass-production units would cost considerably less.

Arduino vs. Simon
From the MAKE Flickr pool
Carl decided to test the limits of the Open Source Electronic Game Kit by letting Arduino give it a go. He wired it up for proper control and after three hours of chip versus chip recorded the following …
Apologies - I suppose that's a bit of an ending-spoiler for all you hardcore gamers out there ;)

CRAFT Video: LilyPad Arduino Bike Patch
In this intermediate soft circuit tutorial, I show you how to make a light-up patch that can be used on your backpack for fun and bike safety. If you missed my LilyPad Arduino 101, you may want to watch that first. The theme of this year's Maker Faire is "Re-Make America" so I thought I'd add some red, white, and blue LEDs to my messenger bag. I added them to a removable patch (from the fatlab, an artist collective I'm part of) so I can easily remove it at the airport, in the rain, etc. I used a rechargeable lithium polymer batter to power the whole thing because it's flatter, lasts longer, and can be recharged instead of thrown away. I also made an Instructable where you can find links to all the supplies I used. You can download the source code and schematic for this project to get started on your own!

Make: Talk #005 Part Deux Over w/ Tom Igoe
I borked last week's show 15 minutes into it. Amazingly, we were in the process of talking about failure and embracing it, learning from it. So we kept the episode. Listen to the brief discussion and then hear me muttering to himself as I try to fix my screw-up. Hilarity ensues. So, THIS week, we'll finish talking to Tom Igoe, one of the developers of Arduino (and I'll try not to hit any wrong buttons).
We'll also present some news from the world of making, and our favorite tricks, tips, and tools of the week. Be sure to call in for prizes that we'll award during the program! The number is (646) 915-8698.

Arduino Controlled Servo Robot Kit
Our Price: $175.00
The Arduino Controlled Servo Robot Kit, also know as SERB, is a great open source project that includes everything you need to begin experimenting with robots and Arduino microcontrollers. Just assemble the precision laser-cut parts and you are off and running, no additional hardware is needed. It even comes with a demo program pre-loaded onto the Arduino.
The SERB has a built in breadboard that sits on the top of the robot. This allows for easy access for additional sensors and electronics. It couldn't be easier to prototype on the fly with this amazing robot.

Updated Power Glove with Bluetooth and Arduino
Power Glove 20th Anniversary Edition -- Build Video from Matt Mechtley on Vimeo.
Matt Mechtley is responsible for this maker's dream project: getting a classic Nintendo Power Glove to work with custom games by replacing it's brain with an arduino, implanting an accelerometer for motion detection, and using a bluetooth modem for wireless connectivity. He's outdone himself with downloadable code, schematics, this awesome video, and an Instructable to top it off. You may remember Matt from my asphalt mosaics video, or from the many appearances of the video games he works on around the internet. Matt writes:
I always loved the Nintendo Power Glove. Not because it was a fun or useful peripheral -- it wasn't. In fact it wasn't bad, as Lucas asserted, it was absolutely terrible. Only two games were ever made to work with it -- Super Glove Ball and Bad Street Brawler. You could use it with other NES games of course, but it was just an obfuscated controller. Plus, it was horribly imprecise, and since it required a sensor bar to find its orientation, you had to hold your hand at shoulder level all the time. No, I loved the Power Glove for what it represented -- a precursor to virtual reality, a way for humans to directly manipulate computers, like an artifact from some sort of alternate future Earth.
I realized one day that we're actually living in that future. It doesn't look the same as we imagined it, but the necessary elements are all there. It's been 20 years now since Mattel released the Power Glove, in 1989. Especially in the last few years, the availability of sophisticated sensing equipment to hardware hackers has grown by leaps and bounds. Technology like programmable microcontrollers, accelerometers, and Bluetooth are readily available -- and cheap. In short, the time is ripe to re-make the Power Glove -- and make it right.

Tasty tweets
BakerTweet from BakerTweet on Vimeo.
Via adafruit comes this awesome use of embedded tweeting, a bakery device that can alert hungry stomachs to what (please don't make me say it) tweets are coming out of the oven. Sweet.
The BakerTweet prototype is made up of an Arduino Duemilanove, Arduino Ethernet Shield, Ladyada Proto Shield, a Linksys wifi adapter, and a whole bunch of little parts that make up the rest of what you see. We went through a couple of weeks of prototyping until the we settled on all the final components and wiring.

A Tale of Two Pongs: Arduino Mega
Tom Igoe just sent me this really cool project that he made on the Arduino Mega and in Processing. He used (2) 8x8 LED matrices and an Arduino Mega to recreate Pong. Next, he ported the Arduino code over to Processing. He said it took 10 minutes to port the entire code. That's fast! You can see the LED matrices in action in my post from yesterday. Check out the link for detailed instructions of both projects, a video, and the source code. Thanks Tom!
When I start learning a new platform, I have a simple rule: If you don't know what to do with it, make pong. What I love about pong is that it's a simple rule set, easy to understand, and implementable on just about anything with a pixel display. You can generally implement it in a day or less on any platform. And it's a great example of engaging interaction. People understand what's going on right away, and, when implemented well, it's just challenging enough to keep you engaged for several minutes at least. That's good interaction, to me.
More about A Tale of Two Pongs: Arduino Mega
Update: You can now pre-order the Arduino Mega from the Maker Shed!
Update #2: Don't forget Tom Igoe will be our guest on Make: Talk this Friday at 12 noon PDT, 3PM EDT. More detail here!

Arduino MEGA video featuring Tom Igoe
I stopped by Eyebeam in NYC on Tuesday to chat with Tom Igoe about the new Arduino MEGA and few other projects that he is working on. I took a quick video and some pictures of the new board to share with our readers.
If you don't already know, Tom is the Area head for physical computing classes at ITP. He also wrote two of my favorite books, Making Things Talk and Physical Computing (with Dan O'Sullivan). Did I mention he is also part of the Arduino team? Now that's cool.

Eyebeam is a really cool space. I haven't been there before, but I have heard a lot about it. Hopefully I can check it out more in the future. It looks like a great place to be creative.
