A LAME attempt at levitating AC

[saturated]

I wanted to modulate ? DC with AC or vice versa

So I got a 1500 ohm resistor and put some AC across it through a VARIAC and transformer

Got a nice little sin wave

Next I thought ok cool now it's time to add some DC and I can make the sin wave go up and down

Seems I forgot that a DC power supply will ground out AC

So I'm gonna have to think about this one for a while 

I think one thing I'm noticing is maybe have a small miniscule AC and a large(r) DC

Hmm oh yeah now I'm starting to recall seeing something like a diode clamping circuit

Might be time to check it out

This worked pretty good and was easy to set up

I couldn't get much separation 

Sorry for the strobe light display

So starting changing out different capacitors and resistors trying to achieve lift off for channel two but despite my efforts they stayed close and tied up comingled like two fighters that the referee is constantly trying to separate 

The point of this I'm still not getting the AC vs DC thing so I'm trying to take a look at various aspects

This will be a good opportunity to maybe learn a few things

Put the DC supply in series, between the bottom end of TX secondary and ground.
Your drawing shows it in parallel, across the TX secondary.

Man....  
I have to say I'm totally floored 

Started hooking it up

I can't believe what I'm seeing

PACO's not even turned on yet and the AC is traveling through its neutral and the 22k resistor

Now I'm scared to turn PACO on

What neutral, what 22K?  You are scaring me a bit now so maybe stop til you can draw out what you are doing.

Dude IT WORKS

At first it "didn't work" because I had the scope on AC but then I switched it and

LIFT OFF

sorry about the flickering scope display it literally drives me BANANAS

R1 value (22k)  randomly selected

Great.  Just to clarify, what concerned me was the use of the word 'neutral'.  That is a very specific term which is only used for one side of the mains AC line.  As soon as you use that word, it raises concerns about electrocution as it is one side of the 'live' AC coming out of the wall.

So I think you probably meant the (-) or 'common' terminal of PACO.  'Common' is the best word to use for a reference point that is not necessarily tied to ground.  Like the one you just made that is floating on DC.

Holy cow  wow ok

Yeah I can understand your concern that does sound pretty messed up like I connected it to the power cord 

Btw this raggedy a$$ house is all jacked up

I don't think any of the three prong outlets are actually grounded 

One time I looked it up and I think it said measure AC from the ground socket and the neutral/common
If you see a difference there's a problem
