XY Monitor / Display
Posted: Sat Jul 28, 2018 4:11 am
Hi guys,
When I was a kid (and stupid) I used to cut the horizontal/vertical coils (electromagnet) from a TV... and then I could control the position of the dot with a battery. I seem to recall it was extremely small voltage to drive the dot around.
Now I have lately been thinking of doing the same thing with something more appropriate that would not get me electrocuted by that nipple on the top. My heart cannot take that anymore!
I believe there must be an XY Scope / Display / Monitor but nothing I see on Ebay seems to fit the bill. I remember way back when Asteroids was drawing the graphics by controlling the coils... at least the circuit diagram indicated that. What is the correct terminology so that I can find something like this? I want to control the x,y, and intensity.
I have seen an NBTV built where someone was built circuits to drive the tube itself... god if I attempted to do that, it would serve to kill me. No joke.
Sure I could draw it on an LCD or computer screen but a tube would look much cooler (IMHO). I do have Laser Galvo set which would also seem fun but I don't think it would move fast enough.
