Oh and also I put the 15ohm resistor on it because it kept firing on accident, by just me touching it, or hooking it up to the vga cable. I just tired it with a 1K resistor on the Gate, and it works great. But I know it will mess up as soon as I try to touch it.
So here is the deal, I can use a battery and open the Gate on the Thyristor, And I read 5V.
Now when I power the gate through to OPTO, even though I read 5V out, it drops to .10 at the gate? That make ZERO sense to me..... Is the OPTO not able to handle the Amps that is needs to over power the 15 OHM resistor on the gate? But that dont make any sense either....... hhhmmm
UPDATE: I didnt put the resistor to power the LED on the OPTO, and got 2.04V at the gate of the Thyristor. I gues there isnt enough Amps to open the gate. Any ideas?
