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.
Peter wrote in to share his build based on our Tennis for Two video game project.
He has more pictures up in his post.
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.
Pumpkins are being featured today on a special Halloween edition of Maker Camp, and I’ll be there, showing our Snap-O-Lantern project. Tune in at 5 pm (Pacific), today, Thursday, October 10.
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:
Eric Weddington of Atmel shows off a wafer full of ATmega328P chips (as found in Arduino and many of our own kits) at Maker Faire New York.
That’s about 1500 chips on an eight inch wafer, and not something you see every day!
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 email@example.com for more information about attending.
Kilobots are small, low-cost, open source vibrobots designed by the Self-organizing Systems Research Group at Harvard to study swarming behaviors. A group of these bristlebot-inspired robots were demonstrated at the Open Hardware Summit.

William Phelps recently wrote to us with alternative firmware for Alpha Clock Five, our oversized alphanumeric LED clock/data display kit. His firmware adds two very welcome features: Automatic daylight saving time (DST) correction, and automatic time setting via a GPS module. It works remarkably well.
Here, we’ll show you how to hook it all up and how to use it.
From our forums comes this interesting question:
”Is it possible to download the contents of an ATmega168/328, essentially backing it up so that it can somehow be restored later?
For example: Let’s say I have lost the source code to a very useful program currently residing on a 328, but I need to flash it with a different sketch temporarily, then restore that original sketch. This would be useful in the case that the chip was soldered directly onto a board – a big mess to try to replace.
Is this possible in some way, perhaps by altering an ISP programmer?”
The answer is that yes indeed, it is possible– with a couple of exceptions that are worth mentioning. And on occasion, it’s even very useful. Continue reading
