Laser scanner oscilloscope test

[phelpe]

sad dat is pointless... kewl for a show off

@phelpe

Not really, If you are working with a modular synth or something, it would be great to have an oversize oscilloscope projected on the wall.

Pointless?? Awesome isn't pointless! I'd say 80% of going to the moon was just for the shits and giggles.

[fujitsulifebooke342]

I want one!

[jotaemebee]

hehey, bastante conseguido! llevo tiempo buscando un par de galvos aqui en españa, donde los has pillado tu? cuanto cuestan mas o menos?

saludos!

[masterpj55]

AWSOME!

on what DAC does this run?

[danz409]

not only is the scanner o-scope badass. but that music is pritty badass as well.

[bloodpawkat]

or a daxter

[bloodpawkat]

its more like a runescape song

If you don't mind, look for another vid of a demo called "Youscope" as displayed on an oscilloscope...  I suggested a very hackish way of working with it to make a laser show (if headphone speakers as crude mirror solenoids isn't a hack, dunno what is), but you seem to have the materials/knowhow to be far ahead of me. Getting the visuals to work with a soundcard or MP3 player driving the X and Y beam deflection via the L and R channels seems straight-forward enough.

@pauljs75 In fact, youscope was one of the first things I tried on this scanner. It doesn't work well at all, though. The issue is that youscope is meant for a CRT (an oscilloscope), and the CRT beam moves much faster than my laser. You could see the larger shapes but the text wasn't readable and some of the effects just appeared as garbage.

@marcan42

Ahh, shoot! Darn inertia getting in the way! I didn't think the response rate would need to be that fast! Then again, watching a video probably cuts out some detail relating to just how fast the scan rate is in its relation to achieving the effect. Perhaps if there were a way to alter the software to do what it can with a slower beam movement... It likely wouldn't be as smooth, but there might be less jitter/garbage while still using persistance of image to mainain some effect.

[pauljs75]

Yet knowing this gives idea for some tests. They would involve a set of frequency sweeps using different waveforms. Not only would this help establish the limits of performance, but there may also expose undesirable resonance and secondary vibrations at some freqs. The only way I could think to improve performance would be to go smaller with the mirrors and solenoids (less mass), but how far that can be pushed while maintaining precision within a small hobby budget is another question.

AWESOME, also, whats the music, that's really cool audio u got going on there!

[kLiNiKaL09]

wtf i wantz :D

[TengoUnOboe]

muy guaaapooo :D!

[pwnage97]

awesome! how can I make one?

[gordy12gg]

Awesome

[antisony2008]

marcan como va la scene de DSi?

[Alexrose12345678910]

Also, Monkey Island ftw.

[Alexrose12345678910]

That's so cool

[mrmaltloaf]

you need to blank on the flyback ;)

[marcan42]

Yeah, I rigged this up with an unmodified laser pointer in 5 minutes. I'm waiting on a second laser pointer so I can take the better one and tear it apart. Then I'll add a modulation input and make it run on the PSU instead of batteries :)

Hi, very impressive.

I'm in the UK and am trying to get Jody Sanders site taken down but I need permission from devteam members to act on their behalf. I'm currently submitting a DMCA format request to Rackspace (iphoneunlockuk's hosters) and I need a little input. Sorry for the convoluted way of making contact.

[Hauserich]

Monkey Island Theme kicks ass :o)

[TheBoff321]

i want one!!

[iAppleVids]

awesome

[gali87]

amazing

[therealmetroidmaniac]

that looks awesome.
