Proximity activated Snap-o-Lantern

I heard you on Science Friday talking about halloween, went home and looked on your website at Snap-O-Lanterns, and was inspired.  I added a phototransistor and infrared LEDs to make a motion sensing small pumpkin that can try to bite you.

Thanks for sharing your project, Gabe!

If you built a Snap-O-Lantern or were inspired by any of our Halloween projects, we’d love to see your photos in our flickr group.

Snap-O-Lantern Kit

Just in time for Halloween, we’re launching a Snap-O-Lantern kit. You can still build this robotic snapping pumpkin from scratch using our original instructions, or you can do it the easy way with this kit, which uses one of our ATtiny2313 target boards and has all the parts you’ll need— except the mini-pumpkin and three AA batteries.

We’re putting the full documentation for the kit on our wiki.

LED Vertical Blinds


dinofizz posted in the forums about the LED display based on the Peggy 2 he installed on his vertical blinds:

I had custom PCBs made to help daisy chain the vertical blinds (they’re sitting on top of the horizontal beam from which the blinds hang). 300 ft spool of 16-way ribbon cable completely used up. Around ~4000 individual solder joints, and I’m still using breadboard to hold things together at the moment! Took me forever.

He linked to a few more build photos over in the forum post, and he even posted some video of it in action:

Atmel Maker Community Panel

This week is Maker Week in New York, and on Friday, September 20, Windell will be moderating the Atmel Analyst Panel: The Maker Community and Education. Panelists will include Massimo Banzi of Arduino, Quinn of QTechKnow, Reza Kazerounian, Bob Martin and Sylvie Barak of Atmel, Brian Jepson of Make Books and AnnMarie Thomas of the University of St. Thomas. The event will be at the Hilton Manhattan East at 11:00 am, and walk-ins are welcome. You can contact pr@atmel.com for more information about attending.

Doomsday Atomic Alpha Clock Five Project

From the complete overkill department, evilandy posted in the forums about his project which hooks up an Alpha Clock Five to a GPS module, a WiFi module, a WWVB Atomic radio receiver, two TXCO RTC modules and two microcontrollers because, well, we’ll let him tell you:

I wanted a clock that would display precision time and date in “all” worst case scenarios. If this clock does not show the precise time then it’s time to gather up food, water, ammunition, and the family and head for the underground bunker!

The keyswitch, fire button, and covered toggle are nice touches. Thanks for sharing your project, evilandy!

Lego and Arduino Projects Book

Our friends John Baichtal of Make Magazine, and Adam Wolf and Matthew Beckler of Wayne and Layne have recently released their collaboration, Make: Lego and Arduino Projects, with a forward by our other friend, Erin RobotGrrl Kennedy.

If that all-star cast isn’t reason enough to check it out, the book is about combining Lego and Arduino, key gateway drugs into engineering and electronics. To accompany the book, they’ve created Bricktronics, a library for use with Arduino and Lego and a set of accessories to help with the physical interfaces, including a shield that allows you to plug your Lego NXT accessories into your Arduino. In an article over at Make, John points out that models and code from some of the projects from the book are up on github, so you can already get started playing.  Neat stuff!
