This newsletter was released on November 29, 2010.

Hi! This is the sixteenth edition of the NerdKits Newsletter, which we publish ~monthly to keep you and the world up to date with everything going on at NerdKits.

  1. Give a NerdKit as a holiday gift!
  2. New video tutorial - Robotic Xylophone.
  3. Awesome customer projects.


For the holiday season, we want help encourage our current customers to give the gift of learning, and help us bring electronics and microcontrollers to as many people as possible. Just like last year, we are giving you an incentive of $20 store credit for every additional NerdKit you buy as a gift through the end of 2010. After your purchase is complete, a NerdKits store credit of $20 will be automatically added to your account, so you can pick up extra parts to further your own projects.

For more information about our store credit system, please visit your store credit page at:

If you want to take advantage of this holiday season offer, make sure you are logged into your user account on our website, then head over to our store:

With the holiday season approaching, we are always looking for a way to add a little Christmas spirit to our office. This year, we thought it would be awesome to have a musical instrument that we could control with a NerdKit, and have it play Christmas carols. Keeping true with the NerdKits spirit, we decided to build a xylophone, build the whole thing from scratch, and teach you some new concepts along the way!

See the video tutorial at:

In the video tutorial we not only document how we built the robotic xylophone, but we also cover solenoids, a little bit of the theory of electromagnets, and even shift registers! As always, we explain the concepts behind the project as well as provide the source code so you can work these ideas into your own projects.


As we do in many of our newsletters, we would like to take this opportunity to highlight a very interesting project that was recently posted by a customer. User Hexorg has been working on his RGB LED Display for a while, and he recently finished what turned out to be a very impressive project. He has a 16 by 16 array of RGB LEDs that he controls using shift registers. On top of his display he wrote a fully functional Tetris game! The display looks fantastic, and it is a great example of what is possible with a NerdKit. Check out his forum posts about his project here:

Or go directly to the video he made:


Thank you for taking the time to read this, and for being such great customers. Make sure you tell your friends and neighbors about NerdKits so we can keep the world's DIY spirit alive!

Best wishes,

Humberto & Mike
