[Isaac] sent in his mashup build of a LED cube combined with a graphic EQ meter. The build is fairly simple and from the video we can tell that his build would be a great installation in a dubstep venue. While it’s not the 9x9x9 cube possible with some judicious coding we think it’s a very fitting display for the intended purpose.
[Itay] dropped a link in our inbox about creating a simple video game system using Arduino. Yes we all know where that is going … the TV out library for Arduino. However this tutorial should still be mentioned because it pretty much covers everything someone new would need to quickly and easily hook one of these things up, along with wii Nunchuck usage, library basics and creating your first game.
Lots of large pictures, diagrams, and explanation of software is included. Yes we know we feature this little setup a lot, that is because its so darn fun. So if you ever wanted to make your own little video game system (without going crazy bit banging VGA out of a little micro in ASM) this guide will help you get started making that next arcade masterpiece.
Instructables user [dustinandrews] just took the wraps off his latest creation, a DIY Arduino Pro Mini clone.
Actually, to call it an clone is technically incorrect – while he aimed to produce a tiny Arduino-compatible board, his goal was not to replicate the Mini’s design. Instead, he developed a 1” x 1” board from scratch, covering the construction process in great detail.
When you are working with components this tiny, the only reasonable way to get things done is via solder reflow. He walks through the steps he took to produce the board, which should be enough to guide those doing reflow for the first time through the process without too much trouble.
The end result looks pretty nice, and when he puts it up side by side against the Arduino Pro Mini, his board can definitely hold its own. While his design lacks an on-board power regulator and reset button, he does provide two more analog I/O pins than the Mini, along with several other enhancements.
For anyone that works in a large office building, odds are you know the pains of dealing with a poorly regulated HVAC system. [Robovergne] and his co-workers recently moved to a new location, and found that the air conditioning control was less than effective, leaving the office as hot as a sauna or as cold as a meat locker.
While they manually triggered the A/C on and off every half hour for a while, that grew tiring, so [Robovergne] decided to take things into his own hands. He had never used an Arduino before, and figured that regulating the air would be a great first project. He mounted a small hobby servo onto the front of the A/C remote, and wired a DS18B21 temperature probe to the Arduino. A small pot is used to adjust the temperature setpoints, which are displayed on the attached LCD screen. Now, when the temperature starts to rise, the Arduino triggers the servo to turn the air conditioning on without human interaction.
[Robovergne] says that while his solution is ugly, it works quite well. It definitely gets the job done, we can’t argue with that!

The crew that brought you the Arduino is always hard at work trying to bring the community closer together and to foster collaborative development. They recently rolled out a new feature on their site that is sure to be of interest to Arduino veterans and neophytes alike.
Arduino Labs is a platform which the team plans on using as an incubator of sorts, for projects that are underway, but not fully baked. Currently, they have highlighted two in-progress initiatives, including the Arduino Mega ADK, as well as a GSM/GPRS shield that the team has been developing in collaboration with Telefonica I+D.
As of right now, the site looks to be a one-way information outlet for the Arduino team to the community, but they stress that their aim is to create a more open development process within the Arduino project. While there is no official statement on the matter, we hope that the site will eventually allow members of the community to offer both their feedback and lend manpower to forthcoming projects.

The team a Zunkworks wanted to build a device for people who can’t normally use a keyboard and mouse. The Bluetooth Morse code keyboard is what they came up with. This build gives the user full control over the keyboard and mouse using a single button or a sip & puff interface.

[charliex] from Null Space Labs wrote in to share a project that he and the rest of the gang have been working on over the last few weeks. The team has been remixing and building clones of the Google ADK demo board we saw earlier this year, in hopes of getting a huge batch prepped before Defcon 19.
Their version makes subtle changes to the original, such as extra header rows for Mega AVRs, higher quality RGB LEDs, and a nifty pirate-Android logo. They also added the ability for the board to send and receive IR signals allowing it to be used as a TV-B-Gone, as well as in more fruitful pursuits. The Arduino board used with the ADK has only undergone minor revisions, most of which were layout related.
[charliex] hasn’t mentioned a price for their improved ADK boards, but we’re guessing they will be substantially cheaper than the official Google version. In the meantime, check out their site for a boatload of pictures and videos of these boards undergoing various stages of construction.
