Moped Turn Signals, Now With More Cowbell

June 7, 2019 by 14 Comments

Cue up the [Christopher Walken] memes, it’s time for moped turn signals with more cowbell. Because moped turn signals with less cowbell are clearly the inferior among moped turn signals.

It seems that [Joel Creates] suffers from the same rhythm recognition disorder that we do. The slightest similarity between a rhythmic sound such as turn signals, and any song in our seemingly infinite intracranial playlist cues up that song for the rest of the day. [Joel] heard “(Don’t Fear) The Reaper” in his turn signals, and that naturally led to a need for More Cowbell. So with a car door lock actuator, a relay, an improvised clapper, and a lot of hot glue and cable ties, the front of his scooter is now adorned with a cowbell that’s synchronized to the turn signals. The video below shows that it’s of somewhat limited appeal in traffic, but at least [Joel’s dad] was tickled pink by it.

Kudos to [Joel] for marching to the beat of his own [Gene Frenkle] on this one. It may be a little weird, but not as weird as an Internet of Cowbells.

Turntable Sequencer Keeps The Techno Beat

November 25, 2015 by 5 Comments

We’ve got to admit, we don’t have any idea what to call this hack. Artist [Graham Dunning] refers to it somewhat dryly as the “Mechanical Techno method”, but that doesn’t quite do it justice. We’re thinking “Turntable-sequencer-synthesizer-beat-box-dub-stepper thingy. With cowbell.”

Call it what you will, but [Graham] has really gone the distance in extracting as much sound as possible from the humble turntable, which is used as more of a synchronizer than a sound source. Although it does play records too – at least part of them; [Graham] masks the grooves and anchors the tone arm so that only part of a track is played. Other records are masked with conductive film over which wiper contacts are placed, providing triggers for various synthesizers. Particularly clever is the mechanical percussion section; a record is cut radially to form cams that mechanical followers trip over periodically to hit either the cone of a woofer for bass notes, or a cowbell for – well,  cowbell.

It may not appeal to everyone, but you’ve got to admit there’s something mesmerizing about watching this rig in action. The beat is pretty catchy, and as you can see in the live performance video after the break, there’s a lot of room for [Graham] to express himself with this instrument. We wouldn’t mind seeing how Compressorhead would put this rig to work in their performances either.

Internet Of Cowbell

April 5, 2015 by 15 Comments

If this is a sign of the times, the Internet of Things promises a lot of entertainment for hackers who can come up with wacky ideas and interactive projects. [Brandon] built a cowbell that rings when you tweet #morecowbell. Why? Because!

On the hardware side it is quite simple, and can be built in a number of different ways depending on the parts you have lying around. [Brandon] used an Electric Imp and its corresponding breakout board. A Sparkfun mini FET shield helps drive the solenoid that hits the cowbell. And because he had one lying around, he added a counter across the solenoid to count the number of times the Twitterati have rung the Cowbell.

The code for the Electric Imp consists of two parts – the “agent code” that runs on a server in the Electric Imp Cloud and the “device code” that runs on the imp itself – and is available at this Git link. Once you tweet with the hashtag, the Cowbell replies back, randomly selecting one from a list of stored responses. Would be nice to see a video of the Cowbell in action. And if it can be made to play the Salsa beat.
