After watching a few videos and reading some posts I decided to try and make my own Oscilloscope, I have a VERY old tv which I have converted, the tv it's self has 4 leads I presume two are for x axis and two are for the y axis,
To make this easier I will name each wire according to the colour
1 is blue
2 is orange
3 is black
4 is yellow
Now blue and orange are connected to the top deflection pad and black and yellow are connected to the bottom deflection pad,
To generate a signal I have used my computer to play a song and attached a amp in between the computer and the tv to boost the signal.
All I seem to get is a vibrating circle not a horizontal line with "bumps and peaks" on the axis
In case somebody asks I have orange and yellow in the + terminal and blue and black in the - terminal of my amp... anyone have any ideas of how to get a proper oscilloscope wave on the screen?
