OT: Equipping synth (or guitar FX) with a WOBBLEVISION

[maximee]

Hello everybody,

I'm currently building my Soundlab Mini-Synth DIY synthesizer and I want to beef it up with some cool mods...
One thing I'm planning to do is to add a thing called the "wobblevision" into it...

If you don't know what I'm talking about, check this out:

But the thing is: I don't want to use a normal sized TV. Instead I plan on using one of those mini TV that you can hook up to your 12V car battery...

Do you think that this will work similary with a smaller TV-tube?
It would be REALLY cool to see your synth sound on a built in monitor!!!
What do you think?

can't stop thinking about this...
how would I implement some sort of LCD oscilloscope?
(i know, it's getting ridiculous )

Wonderful opportunities for destroying TVs, destroying amps, and electrocution here, just for the sake of a crude Lissajous figure?

I you're going to try something like this, use an old computer and a couple of cheap AD converters, don't mess with CRT voltages.

Ge_Whiz: I know, you are correct...electrocution is a risk here :/

That's why I was thinking of LCDs now...Using old computers means that this gimmick would use quite a lot of space which I don't want...
A plus for an old b/w CRT would be its crappy analog looks which I like very much...

Can't get it out of my head. Still...  :roll:

hhhhmmmm doesnt seem to tricky to me. we have an old TV sitting about somewhere, i might have to give this a go tho i think ill try to rig some sort of impedance matching circuit inbetween the CRT and the audio source. methinks there will just be alot of playing about to do
