My flyback-transformer

Me drawing some archs with my home-wound fly-back-xformer.
Secondary aprox 250 turns. Primay 5 feedback 2.
Yes , and only driven by 5 volts from an old PC PSU.

(The tv is on in the background. A program about the Munich massacre )

4000 germans? what about them?

Oh : )

The tv was on in the background.

A program about the Munich massakre during the 1972 summer olympics.

More secondary turns means more voltage?

[Flapjackbatter]

@TheError404

Yes. More secondary turns = higher voltage.

(Or to be more correct; it`s the ratio between primary and secondary turns.)

Upload soon a video of your flybach working at 12V, the transistor resist about 24V.

I`m probablu using the "wrong" PSU.

It`s an _old_ pc PSU capable of 14 Amps on the 5V line and just 4 Amps on the 12V line.

I am currently in the process of winding a new secondary , but as you say I could benifit much from a better PSU. I`ll see what I come up with :)

@Flapjackbatter oh i see

[powermaks]

@Flapjackbatter if its based on ratios, less turns should = higher voltage

[SmashCOBamberg]

the arcs sound funny cool vid btw

Actually, i'm making a 555 timer flyback transformer with a 102K cap (1nF).
