Bit of a downer that we didn't get to see the scope work as good as it should've...but I def look foward to seeing the improved version. Keep us posted.
No you wont get kill of the discharge of the CRT tube. It simply hurt a lot, and for better result put a small amp to drive the coil i use a small lm386 power amp work quite good.
thats relly dandrous because the crt tube can act as a capacitor and the discharge can easaly kill you. I got shocked from a simular experiment but I was lucky.
ive been zapped by a live tv like that and it didnt hurt one bit. all it does is sends a high voltage arc to you and you instantly repel. no damage done, its like one of those trick lighters.
Hi, I'll probably seem like a jerk for saying this, but the "uf" on capacitors stands for Micro-Farad. It's not actually a "u".
Keep experimenting! By the way I tried something similar - when I was a kid I connected the audio out of an amplifier to the video RCA input of a tv. A very osciliscope-like image, but when I turned the volume up the input died. Probably a diode burned out. rats.
its ok lol your not a jerk a jerk will start talking about my mum or some crap lol i no im not good at this but everything i know about electronics is from the net so im limited lol but im getting better.
lol i should have explained it better : you just find the deflector wires the copper coil thingyies rapped around the yoke tube " the gass thingy" and put your signal in the vertical deflector the horizontal one should be left as it is already at a 60hz sweep and makes a sraight line across the screen , i have updated it with an amplifiyer and will explain it better thank you for your comment
If possible, use the vertical drive to run the H deflection coil. You'll get a much better picture. It reduces the H scan to a more audio-friendly rate. Just beware, a lot of TVs if you swap the H/V deflection coils it can screw with the H oscillator and flyback.
Sometimes this messes up the scan size. If this happens, keep the V osc connected to the V coil. Loosen the yolk tension screw and rotate the whole deflection yolk 90 degrees and you're set.
Also, try not running the TV at such a high brightness. Even the lowest brightness setting should be adequate. You may need to turn up the brightness when displaying a string waveform.
man you are way sarter than me , i built this and yet have no clue what your saying lol have built a zvs circuit i need some help with it i have a vid on my delema
I'd be glad to help. I'm at work at the moment (it's my lunch break), but when I get home I'll have a look at your video. I know a bit about Tesla coils so I might be able to help. ttyl.
keep up the good work, seems you get a clear signal somewhere while it's turning on then it gets fuzzy and blurry .. maybe you can do something about it knowing when it happens and control the input better
I jailbroke my iPhone and used an app.

If you have a bad heart/weak heart, the discharge from a CRT tube could cause heart failure.

if you do this, make sure you have a defibrillator and a second person who can useit.

lol thats why i run tin foil over all caps including the transformer and i dont touch it directly that would be silly lol

I already have tried that, the picture is too dim, brightness doesent help :((

what do you mean by this please explain you problem a little better

It is just too dimm, not bright

I think you'll find its 15.734KHz.

i need an audio amplifiyer as the deflector coil only recives 3.5 volts i need to amp it up to 12 causing higher deflection.
