errrrrrr......... welll........ hmmm.....take it to the extreme, make a SMT one, just a thought

referring back to the circuit diagram, do you recommend me changing any of the transistors?you can make inductor from any kind of wire, any kind of metal.
But why would you want to?
Just get some coils, toroids etc.
If you don't want to invest money, get them from a TV set, USB wire, CFL, boombox, you name it.
Or use a MCP1640, this is a SOT23 IC with 6 pins.
I made a jouletheif from a magnetic core memory toroid.
These are very very small. I have thousands of these here.
Same as for toroids or inductors. These are total mass products. They make millions of them. Why bother about them? I understand it's cool to salvage some magnetic core from a CFL etc., but it makes only SUCH an impact... 0.01% of these are salvaged, ever. Or is it?
Bare wire is not used to make a transformer or an inductor. It will short the circuit. Instead the wire has an enamel coating as its insulation.

Well I made one a while back with BC547, it has a continue rated dc current of 100mA and 200mA peak current, it seen to work fine (no magic smoke)but I have encountered another problem. See my latest post about if I should use the transistors from the circuit diagram or the ones the person(from page one) recommended me?
Thanks in advanced.
Sometimes the enamel insulation is very thin, that is why on some of the photos it looks like there is no coating but in fact they do have them but it is hard to tellAll the wires in your photos of ferrite-core inductors have enamel insulation.
Transformers are also made with enamel insulated wires.
To connect to the wire then some enamel must be removed from the ends.
I "stole" some wire from an inductor in a 2-way speaker crossover network and it also had enamel insulation.
