[James] sent us a video of his latest creation: a robotic glockenspiel that’s currently set up to play “Popcorn”. It uses eight servos to drive mallets that strike the tone bars with fast, crisp movements. The servos are driven with a 16-channel I²C servo driver and MIDI shield, which are in turn controlled with an Arduino Uno. The previous incarnation of his autoglockenspiel employed solenoids, dowels, and elastic bands.
[Gershon Kingsley]’s 1969 composition for synthesizer “Popcorn” has been covered by many artists over the years, though perhaps the most popular cut was [Hot Butter]’s 1972 release. Check it out after the break, and dig that lovely cable management. We’d love to see [James]’s autoglockenspiel play “Flight of the Bumblebee” next.
If you’re hungry for more electro-acoustic creations, have a gander at [Aaron Sherwood]’s Magnetophone.

Popcorn Indiana, the same company that manufactures the bags of kettle corn you might find in a convenience store, posted a project on their website called The Popinator. It’s a device you fill with popcorn, turn on, and responds to the word, ‘pop’ by firing a piece of popcorn into your mouth. Details on this build are scant, most likely because The Popinator doesn’t operate exactly as described in the video demo for the Popinator project.
We’re going to call this build a figment of the imagination of one of Popcorn Indiana marketing drones, but the idea behind the project is actually fairly interesting. The idea of using voice recognition to determine when the word ‘pop’ is said to turn on the machine is very cool. Using time of flight to calculate where someone’s head is puts this build into a category of awesome we’ve rarely seen before.
Despite all that coolness, we can’t help but think this project is simply an attempt to “go viral” and get a ton of publicity from random tech blogs using only a video camera and a few hours in Final Cut Pro. You’re welcome, Popcorn Indiana.
Surely there will be a ton of comments for this post arguing the merits of this build. You can check out those comments after the break, along with the official Popinator video.

This video demonstrates square gears and other oddly shaped cogs. We can’t think of a use but it’s interesting none-the-less. [via Tinkernology]
Cooking with Lasers
It’s late and you’ve been at the workbench for quite some time. But why go to the kitchen for a snack? Grab a couple of 1 watt lasers, hot glue a kernel of corn to a DC motor, and you’ll have popcorn in no time.
Calling this a simulator just doesn’t do it justice
Okay, so this link is a Lexus commercial. But it’s worth watching to see the footage of this driving simulator. Inside that pod is an actual automobile surrounded by a 360 degree screen. The room has a full x and y axis to move the pod (and the car) as you drive through the simulated world. It’s like someone gave a bunch of geeks an unlimited budget and say “go nuts”. [Thanks Luke]
What takes the most time in your hacking adventures?
Everyone whose spent some time in web design has run across the peculiar rendering bugs and workarounds associated with Internet Explorer. Internet Explorer Stole My Life aims to tabulate the collective time wasted from the lives of developers. We think it’s hilarious because spending the same amount of time meeting W3C standards and this problem would go away. But [Caleb] mentioned something interesting when he saw this site: What part of your hacking adventures wastes the most time? We’d love to hear about it in the comments.
