I like the idea shown here, my science teacher did this as well but glued the mirror straight to the cone. I've found that if you glue a spring to the cone and then the mirror to that it works surprisingly well. The spring just needs to be stiff enough to only move when frequencies are played.
Very cool! You could try to play a sawtooth wave from one of the speakers, then you'll see the actual sinusoid of the other speaker. A sawtooth will put a lot more strain on the mirror and the rods though, because it returns in one sharp jerk.
The non-linearity is actually indicating the resonant frequency nodes of the system built (speaker and mirror). I doubt that you were twisting the amplitude knob at the same time as increasing the frequency (not amplitude). Cool video.
невероятно, много добре... М оже даа се работи върху увеличаване на честотата, а също и върху затваряне на цялото устройство в кутия с хартиен екран на който лазара да проектира... Браво!
If you can get hold of La0.66Sr0.33MnO3 and shape it into a cube surrounded by coils, then you could evade the problem of mass inertia, which usually makes high frequencies impossible to display properly, since the power of the tiny speakers isn't sufficient for throwing around the mass of the mirror, struts and speaker membranes and coils. Just google for materials, which change their refractive index by applying a magnetic field, then google for companies that produce/sell that stuff ;) Jerobeam's music usually is recorded in 192kHz and 24bits(even 32?), a necessity for creating fine details in his lissajous, which come as ultrasound in a lot of cases, so you can see funny stuff, but basically hear only a square baseline and a phased sine melody with some funky ultra high pitched noise^^ The piece "Nuclear Black Noise" is by far my favorite ;)
You know what'd be awesome for this, if there were some material that had refractive properties like a prism, but could have its refractive index changed by something, say by exposing it to a magnetic field or something. This'd then give us a solid state solution. But I doubt such a substance even exists.
Hello Spudhead: Look up Pockel Cells. In the days before CDs, a company, Discovision (Universal Studios + IBM) I worked for used them to modulate a laser beam to write data onto a glass master video disk that had a light sensitive coating on it like a PC board. Those master disks were then developed like exposed PCBs are then plated. The resulting master was used to injection mold a plastic video disk (Laserdisc) the foreunner to CDs and DVDs. I did not work in the section that did the mastering work but I'm thinking the Pockel cell probably could be modulated quite rapidly since our company produced movie video discs. Magnavox and Pioneer made a videodisc player that played our product.
You Gotta Play Jerobeam Fenderson Music on it!

Cool ! It reminds me of my first Heatkit tube scope I built back in 1972. I kept staring at some interference pattern with it.

Great project and presentation. Thanks for sharing!
Thanks!
Very interesting. Try it with a tuning fork and a mirror for perfect sine waves
*Does oscilloscope music work right on this?*
Did you used signal generator? because I heard so many s/v
Genius !
very nice idea ..but the sound is loud
What a clever design....!
Can you get it to make pictures like at a laser light show?
I wonder if there would be much difference if surface transducer or bone conductive speaker was used instead of regular speakers.

Will take a look. Thanks.
Good. Here on my city has one like this on USP (University of São Paulo) lab, open to people interact, since 90's.
would it work better if you took the cones off the speakers and just used the coils?

woah
Needs more views. Nice Job!
You just inadvertently gave Meta free advertising with your laser light show.
could you post a link to where you found those speakers? i cant find them anywhere!
Excellent work! - Thanks
Genius bro..
nice osciloscope!
Thats Fantastic!!!
What about piezo ?
Awesome 😍
Buddy that was cool!
eddydogleg Thanks!
Neat idea!
Very nice!
TheHue's SciTech Thanks!
tip cut the cone of the speaker and just use the mirror to become the cone
Is this laser on a mirror or on a wood?
Now play jerobeam music :D
right!
lol thanx for jerobeam tag.... i now have a quite a show planned for my project haha
yes, do it! else i will have to build one myself, but im lazy.. sometimes i just stop doing things before i even
Beezow Doo-Doo Zopittybop-Bop-Bop That's exactly what I thought...
A tip: you can watch series at Flixzone. I've been using it for watching lots of of movies recently.
haha :D i wonder what oscilloscope music would look with this? jerobeam fenderson is only one how does it i know.
cool idea
Mmm test for oscilloscope music?
Omg is working 100%
Im still trying to figure out the lm386 tbh. Im in the stone age
Futuristic oscilloscope
Amazing dude!!!
Thanks man!
Lissajous curve shape patterns.
This is fucking awesome.
Haha this has been done mamy many many times. You need reflecting galvanometers to make it quiet and accurate. Speakers dont cut it.
How far away is the projected image?
About 5 feet
I'm so building one.
Easy Fun.
Laser oscilloscope music pls
very impressive : )
Glad you liked it!
I fuckin love this.. Thanks
nice 😃👍
The typical why the hell did I never thought of this device
Nice !
You might want to add that it is an oscilloscope IN XY MODE, though ;-)
Apply time basis signal to one of the speakers and you have normal one ;)
@@____.__._.._ exactly!
Great fo Dj's 😁😁😁😁
you should connect this to a cumputer in stereo then, drive the lazer though the paralelle port !
You'll have a DIY projector :)
What's the geek why are you so stupid? Not are you stupid. Why? Was it an accident? Was it on purpose?
dude chill out. its just a joke. hes just a layman
looks like kylo ren's laser sword
omg you sound like electroboom
this is not a oscilloscope
great xD
Its close to hologram
leinad dolor obviously not.
so not really an oscilloscope, just a cheap laser light show setup. very disappointing.
Well, it's more than a light show as you do get the X input and the Y input.
Its nunya biznez
By definition, it's technically an oscilloscope as in it lets you see oscillations...
Awesome 😍
