Sounds awesome!

The whole cone detonator thing discussed in comments of teaser would be cool, this is alot cooler. Still saying that a camera perpendicular to the line of thunder cans would add a great comparison (at a distance away from line of half the length of line).

9 tubes from initial boom, a t join at every trigger, or each boom sends the sound to trigger the next?

Orion Lawlor

I like that once those air shock fronts are synchronized, they stay synchronized as they travel further along the line between the cans. I think I would have done this with a relay board and an Arduino doing the timing, but then I'd need to figure out the speed of sound rather than using it to send the signal like with your listening tube!

wanted to do a similar thing for years. But without the hose and just with timers. Place them explosives in an 2D-array in order to get something like a plane wave... Glad you did it!!

Max Eliaser

This is a fun project. I'd say the timing was already pretty much dead on.

WizardTim

Well that’s one way to do it! I certainly didn’t think you’d have some Rube Goldberg detonation delayer.

It’s off by about 1/30th of a second. To adjust I need about 40ft of wire added.

I was about to suggest using a microphone to trigger the cap, but if you think about it, you kind of did; It's basically a digital microphone with a bit depth of 1.

Very nice. Also great job on avoiding the ex-word on YouTube :)

On a related note, how close have you ever been to a wild lightning strike. My personal record is 4 metres just a guy in street cloths, and in a car inside the cluster of radiating arcs from a tree getting struck 25 metres away,

That just blew me away.

"Thunder In A Can" is back! As good as it gets.

CodysLab

I’ve been in a truck that got struck by lightning. It struck the water tank on the back. So ~1m. Felt/sounded like someone hit the roof of the truck with a big hammer.

Just a bit of feedback (of course love the video). Even though I don't NEED the metric translation I'm never bothered to look it up so it helps when you put it on the screen. Greetings from Melbourne btw :).

heh, thunder in a can...

You could use something like a clap circuit. A cheap microphone with an op amp, edge detector and a transistor latch. The delay from that would be more like micro seconds, and the delay from the explosion can be compensated by placing the charge further away from the microphone. A circuit like that would be easy to produce 10 or more of for very cheap
