Guitar effect project w/ oscillator project question

[lancefortnight]

I have this idea for an all-in-one rockabilly machine that would sit on top of your amp. It would be a tuner, delay, preamp and oscillator all in the same box

my question is about the oscillator. There are 4 poles, two are for the vertical and the other 2 are for the horizontal. You leave one set attached and the other set you plug in some audio and it looks like an oscillator. The only thing is right now, the oscillations seem to be plateauing at a certain height. Any one know how I might get this going right?

color me confused, how is an oscillator used in rockabilly?

EDIT: wait, do you mean oscilloscope?

I drew a blank on this too... Oscilloscope. No sound on the video so I can't tell what kind of signal it is getting. If you are using a distorted guitar it will be "clipped" giving the waves "plateaus."

What kind of O-scope is that?

Welcome, Lance.

Oscilloscope.

Actually a CRT TV set, out of its SAFETY cabinet (exposed 12,000 Volts!), modified.

The video suggests they just disconnected the H-sweep on the yoke and connected the winding to an amplifier speaker output. The 60Hz V-sweep, turned sideways, is often a fine sweep for music. The disconnected H-sweep driver is throwing huge pulses, very dangerous.

I still have scars from CRT TV sets. I would NOT use it that way. I would not use it in public without a better cabinet than home TV sets have.

I have an old tube radio cabinet that I'm housing it inside. Do you think that would be safe?
My other question would be, do you know a way to make the waves not plateau?

Wow. Dunning-Kruger all over again.

no. in fact, basically, nothing you do with that will ever be safe. i've never even changed oil, want me to fix your brakes? you'll probably survive, right?

I definitely wouldn't be watching that on it not unless I had my marigolds on

> waves not plateau?

You need a bigger amplifier. Possibly ridiculously big. Maybe hundreds of Watts.

There ARE ways to to convert audio to RASTER, rather than directly jizzing the yoke. Then you do not have to go inside the TV set's HIGH-VOLTAGE area, can use "any" TV set, even LCDs.

A little update on my project. I tested it out and the delay still works! Next I'm working on getting the tuner to stay on so that when the power gets turned on, I don't have to push the power button on the actual tuner. It's turning out to be hard.

As always... R.G. has made me smarter....... again!

Thanks man!
