How to make a Plasma Globe from a lightbulb without rewinding the flyback? Answered

This is another Ible where the writer doesn't know what they are doing: as soon as you read "Transistor gets very hot", you know they aren't running the thing correctly

What about the whole circuit isn't right and what could I do to prevent this?

Look at my instructable on flyback transformer theory. The problem is overdriving the transformer.

In general the circuit is good what is off is the number of turns on the flyback primary most flyback drivers use 10 turns and for that mosfet you do not want to exceed its wattage. The IRF540 is a 150 watt mosfet and you don't want to put more than 12.5 amps through it at 12 volts or it is over wattage. You want to keep the wattage down to keep the transistor cooler.

You can find a number of flyback drivers on the net by Googling "Flyback Driver".

You can look up the datasheet here:

Don't tell him that now you might deprive him of watching a transistor blow.

I didn't even read the Ible I just answered his question about the flyback.

Reading instructions avoids asking nonsense questions.
