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.

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.

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

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.

lol all caps were discharged before i started including the transformer

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

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

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.

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.
