Spring reverb is something we’re used to hearing about when it comes to guitar amplifiers. It’s a coil spring stretched the length of the amp’s housing. One end is fed the guitar signal, with a pickup at the other to capture the output. But this spring reverb is on a much grander scale. [Jochem van Grieken] strung up 100 meters of coiled steel wire in a long hallway and the results sound a little bit evil.
A simple piezo element is used as a pickup to amplify the sound coming off of the spring. Above [Jochem] is using what looks like a jeweler’s saw to make some sound on the 3.5mm wire. It’s this portion of the video that sounds demonic to us. In the second half of the demonstration he strikes the wire with a ruler to produce the pew-pew effect from many a sci-fi movie.
This isn’t his first experiment with the concept, it’s just his largest. Also found after the break are a pair of links to his other installations.
WOW – Those are some seriously cool sounds – Very analog :-)
Star Wars Episode 7.
Love it, sounds like the train approaching sound you get sometimes, presumably due to the tracks vibrating as a train hurtles along them
I think that sound comes from the tensioned catenary twanging as the pantograph runs along it.
Ouch! …really well made and scary!
You may want to contact this guy and arrange a gig:)

That’s real horrorshow stuff!
Sounds a little like when you attach a slinky to the bottom of a plastic cup… Keeps your kids entertained for almost 10 mins!
Now imagine if that slinky was 100m long and instead of a cup you used a piezo element!
If Satan had a slinky this would be it.
I freakin love it! Imagine if it had an arduino, lol
If it had an Arduino, the internet itself would combust!
I loved doing this with a giant slinky attached between my dresser and a shelf as kid, always wanted to scale it up.
Awesome to see a childhood dream come to life.
Way cool, reminds me of this:

OMG LOL, best one yet :))
hahaha ! thanks for this link. It made me laugh at work :)
wow, that first video sounds very similar, thanks for sharing!
And chewbacca has a habit of showing up everywhere

This reminds me of an old delay line I saw once. I think the addition of some kind of feed back might be an interesting twist. Maybe with the option to inject sound.
If you could get it to resonate it would act like some kind of acoustic tesla coil :D
Now to find a way to generate a freqency high enough to make a tesla coil out of strait wire at optical frequencies (: it could make for some efficiant lighting (:
Maybe thats how they should power the space elevator, if they ever get round ro building it, match the cable to the earths resonant frequency.
All well and good until you draw too much current and the magnetosphere’s field collapses.
Im not sure about space elevators but I have tried injecting sound on one end and recording it with a piezo element on the other side. But with these kind of delay times it gets messy really quick. I will look into some kind of feedback mechanism, thanks for the tip.
And for all of you eager to try, the simplest and coolest way to experience this is to get a slinky and let it hang in free air while clamping it between your teeth. The sound travels through your jaw into year inner ear, believe me, it’s very impressive.
looks like a good delay, how much serial data can be stored on it :)
This + mallet on a string = epic doorbell.
I’m thinkin’ bout my doorbell, when you gonna ring it?
Nice, but 90% of that sound is the reverb he used. Without it, it would have been a very plain sound.
What do you mean? It IS a reverb… The piezo is connected directly to the amplifier driving the speakers, no external processing. In earlier versions I used a bucket to acoustically amplify the signal and it sounds exactly the same.
Way cool!
I see the piezo to pick up sound, how was sound output into the wire: hotglued to speaker?

He also makes a cool ring mod from a vfd!
