Sawtooth generator for TV oscilloscope
Here’s what I come up with for sawtooth signal for the scope. I took the ramp generator circuit from learningaboutelectronics.com It uses 3/4 Op Amps from the LM324 chip. I tested the circuit from learningaboutcelectronics.com and it works in multisim. S1 and R8 controls the frequency. R6 controls the amplitude of the sawtooth voltage. When …

Scopes are expensive and hard to find locally. Here we are going to build one out of a CRT TV. THIS METHOD ONLY WORKS WITH CRT TV, NOT PLASMA, FLAT SCREEN OR LCD TV. The circuit only uses the TV Deflection coils to create a magnetic field to attract the electron beam that the gun …
