@Ist,
as xenomorphlabs says 30 rectifiers, ha ha, welll done Ist, if you connect them all in parallel, you might have to put 30 one ohm resisters in series with them so if one output is higher or lower, than the others it won't pull the other outputs down and over heat.

A bit like using 1 ohm 5Watters on the Emitters with paralleled 2n3055's.

I experimented with a CD rom drive, door tray opener motor today, soldered a RED Led on its output and spun the geared shaft, it lit the led, but the led goes to a certain brightness, then I can feel the motor loading up as I go faster, but the LED stays at 1 brightness level.

Make a good toy wind generator this thing.

@all
I pulled apart the centeral motor that spins up the CD in a CD Rom Drive.
Here it is.

There are 9 poles,
What can we do with this one?

There is 3 x IF4 surface mount black thingies here as well. They have 4 legs on them.

Kudos to those who had the idea of suing a pre-existing fan winding for a res coil - truth is, any transformer will do it all just a matter of how you wire into it.

I might go get one of the camp-lights with the florescent bulbs in it and take it apart - see what's going on in those things...poke around.

@ Ist
Thankyou for your kind remarks, if you do get to pull one of the CD drive motors apart, they are a 3 phase configuration, each phase has a 4 legered SMP ic, called a TF4, I did a web search for this thingie, couldnt find out anything on it.
Theres a mob of tiny loose balls floating inside it, must be something to do with balancing the CD at high speeds.

PS, everyone, the cartoon is for IST when he goes shopping for "STUFF" at the local electronics shop he he he.

@Gadgetmall,
Im pleased that thingie  I sent to you has turned up OK, phew, I am soooooooo releaved, lol.


THIS THREAD NEEDS A BIT OF HELP WITH INSTRUMENTS
@ ANYONE reading this post.

There are two or four forum members who have a VERY URGENT NEED of an OSCILLOPE (Not me, I got one).

So if you live in America, and IF you have an oscillope gathering dust on a shelf (its SURPLUS to your needs hint hint hint) would you please get in touch with PIRATE. (cause he is the forum leader)

Why am I asking? because there are people on this forum that could really use one in their research, and most of us cannot afford to buy
one.
Have I ever helped one of the people on this forum out without being asked? YES, I gave something to Gadgetmall, all the way from DSE in Australia, a brand spanking new instrument, still in its plastic packet.
And it made me feel real good doing this.
Did Gadgetmall ask me to do this for him.  NO, so if this Australian invallid pensioner can do this for an American, what can the Americans do for their own kind?


So come on readers, even an old frequency meter as well.
If you have other types, please feel free to send alsol.

Bill, whoooo boy ain't you going to love me he he he he.
