Hi,
While running around the net reading as much as i can, one thing i noticed is not a lot on toroid, and transformers. in terms of winding and making your own for whatever projects (even if only curiosity).
i don't really want to hash out stuff i can look up (or others can)
but i tried and couldn't find a place that would get the principal.
how far can you step up voltage in a small space?
can you wind 2:20 ratio on a tiny toroid and then chain 5 of them to get a
1:10k jump (at really really tiny amperage with losses)?
I do know that disposable flash cameras get this kind of jump, but theirs looks like one coil with just a high ratio of very fine wire. i have more 32 AWG and 43 AWG Essex wire than i know what to do with.
so i am just trying to learn given that kind of opportunity..
on another issue, can you use a toroid to make a 1:1 isolation transformer?
how would you go about knowing what frequencies it would impede and what range it would let go through?
i would be happy with a link if its way too much to explain, i do realize that each area has its own art behind it and just cause its passive in no way means its really simple. (ie i am realistic)
and lastly.. one project i have on my board is making a simple sine wave oscillator at around 1k H at a known ac voltage. the point is that i want to somehow figure out what the transformers i have are as far as turn ratios.
not perfect, but if someone has a better idea for me figuring the ratio, that would be awesome. resistance isn't good enough when the wire gauges are not the same... (though i guess if same wire gauge resistance would be proportional to length which would be related to turns... so somewhere there is an answer i am missing... no?)
[i have one that is just way to nice not to find some project for]
sorry if these seem like silly questions...
on the FUN side:
anybody have ideas for what you can do with a whole lot of wire, and a whole bunch of toroid s besides learn more about transformers, and high frequency filters (got lots and lots of magnets too) i even ended up with a handful of spark gaps... (came with a 47uf capacitor the size of a small loaf of bread... its discharged (and i have wired a resistor across the terminals as it has no use right now) i live in an apartment so, no large huge bolts of electricity and fire
