Hacking a CRT monitor for distorting visuals and making glitch effects.
Jaskirat Singh Randhawa
We made 2 electromagnets from carbon steel rods (~7mm) as cores and magnet wires using a drill.
We tried the electromagnets on the CRT at different locations and finally settled on this orientation because we found the distortion results quite interesting.
Then we made a transistor circuit powered by arduino to control the amount of magnetisation on the electromagnets. The voltage being fed to the electromagnets from the voltage source is being modulated with the help of this circuit.
Then we connected the RCA connector from the TV to a Raspberry Pi to get some video output on screen instead of just noise.
