In an blog posted today on the Phoenix New Timessite, Troy Farah asks: “Harlem Shake vs. Gallon Smashing Prank: Which Meme Will Destroy America First?” Well, both have caused a lot of problems for smashers and shakers in the United States. We read a recent report about the possible legal issues facing some gallon smashers. And CNN.com posted a story on March 1 about the FAA’s probe into a recent “shake” on a plane. With negative results such as these, it’s clear that the Smash and the Shake are bidding for the most tile of “most destructive.”
Where does the engineering community stand on these pranks? Well, we have not seen an electrical engineer, robot, or microcontroller-based system smashing a gallon of milk to get a laugh. (Thankfully! We don’t endorse it.) But we did recently seen an engineer’s take on the Harlem Shake.
And so the meme continues.

If you read Circuit Cellar and Elektor magazines, you likely have as much passion for old-school electronics as you do for he new, cutting-edge technology you find at events such as the Embedded Systems Conference. Elektor editor Jan Buiting is well-known for his love of both new and old technology, and in his Retronics webinar series he presents some of his favorite old-school technologies.
In the video below, Jan explains how and where he found some of his retronics equipment. He also details how he fixed some of the systems and what he does with them. Examples include:
A Heathkit TC-2P Tube Checker that Jan found at lawn sale
Old audio equipment
A satellite TV receiver
An “Elektorscope” from 1977
1980s-era test equipment

Want to learn more about Embedded Linux? You’re in luck. On Wednesday, November 14, Elektor and Farnell/element14 will partner to run an informative webinar on the topic at Electronica 2012 in Munich, Germany. If you’re at the show, you can attend the recordings for free. Register before October 31 to get free Electronica entry tickets from Farnell/element14.
Attendees should go to the Farnell/element14 stand (Hall 5, Stand 558) for the Elektor Academy seminar, which will focus on the latest developments on the innovative Embedded Linux board. You can watch the presentation and ask the experts questions. The webinar will be recorded and webcast a bit later.
Presenter: Embedded Linux expert Benedict Sauter, the board’s designer
Description: Benedict Sauter will take you through the design and update us on the latest applications.
When: Wed, November 14, 2012
Time: 11:30 CET
Where: Farnell element14 stand (Messe München, Hall 5, Booth 558)
Domotics (home automation) control systems are among the most innovative and rewarding design projects creative electrical engineers can undertake. Let’s take a look at an innovative Beagle Board-based control system that enables a user to control lights with a 10.1˝ capacitive touchscreen.
• An I/O board for testing purposes
• An LED strip board for controlling an RGB LED strip
• A relay board for switching 230-VAC devices
• An energy meter for measuring on/off (and also for logging)
ELektor editor and engineer Clemens Valens recently interviewed Koen van Dongen about the design. Van Dongen describes the system’s electronics and then demonstrates how to use the touchscreen to control a light and LED strip.
As Valens explains suggests, it would be a worthwhile endeavor to incorporate a Wi-Fi connection to enable cellphone and tablet control. If you build such system, be sure to share it with our staff. Good luck!
