Thank you, Jasen, I'll give it a go, but am a newbie to Linux so stillOn 2006-03-16, Daniel <dxmm@nospam.albury.net.au> wrote:
Gareth, any chance you can reduce the size of the circuit Diagram?
Trying to work out what's going on, when you can only see about one
sixth of the circuit at a time, is pretty difficult. Printing it out is
worse yet.
I see you're using linux, install xzgv and use that to view the pic, press z
to zoom out.
Bye.

Weird, Isn't it?
If you can post a schematic somewhere I'll give you a hand.
A book "Propulsion Without Wheels ((memory may have failed me) by LaithwaiteQuite a few years ago one of the Oz electronic mags described a project
that
sounds similar to what you describe - it wouldn't ahve run directly off
the
mains though.
Unfortunately I can't remember all the details - but I think it was some
sort
of coil in a form like the thing you throw quoits onto, and it would
suspend a
ring of aluminium in the air - "defying gravity". If you applied a pulse
to
the coil it would shoot the ring vertically into the air as I recall.
Possibly Electronics Australia, R,TV&Hobbies perhaps.

It is the FZ-1A listed on this diagram.
Oh, that's a horse of a different color.Check out this link to see what I'm talking about:

Think you might need to give us part numbers/photos to find it.Inside the device there is (was) an IC with a coil glued on top.
After a trip (or two) from the table to the floor, the coil is
broken off. Does anyone know the type/manufacturer of the arrangement?
The casing of the IC broke when the coil broke off.

You're looking for a SPICE package:I can't seem to figure out what software to download
there are many options yet none clearly say "circuit simulator".
Something that's sensitive to the voltage in the capacitor and capable ofDo capacitors collect energy and store it until an external event
causes them to discharge. Or are their capacitors that will collect
energy and store it until the capacitor hits some peak level and
discharge on it's own.
Specifically. I'm curious if a simple circuit can be designed where
energy is obtained from a solar cell. The capacitor stores the energy
until it reaches the point that it is full, and then discharges the
energy which can run a very small motor like a beeper motor for a small
time like a second or two.
eeing as I am not a full fledged EE I was hoping to find a schematic or
tutorial with an example of this sort of device that I could use as a spring
board. I could spent months trying to figure out the math involved on my
own. I want to communicate and transfer power across an air gap less than a
half inch. I would like to keep the size of the inductors down to at least
1" in diameter. The power transfer would be to change either a capacitor
array or a battery. I'm looking for a device powered in the 12V to 24V range
for now.

better u use a step-down/buck DC-DC convetor which will give u a nice
1.5v from a 9V battery.
U might be doing this to have longer life of battery.
if u r using 9V - 1.5V linear voltage regulator you will waste a large
amout of power.
So go for switching regulator.
they price less then 1$.
got a source for these?
i would like to change both the pitch and the speed, as theyre
directly related.
i am interested in this so that i could buy some cheap discmans, and
have a control to speed them up or slow them down, so that i can match
the tempo of different songs.
I know i could do this by computers, but would rather do it this way.
---They are only directly related if you are using speed control on tape or
vinyl.
Both are independent for any other use. It is very easy to sped up a
song while keeping the pitch the same or to vary the pitch at the same
speed setting. If it wasn't over half of today's "artists" would be out
of work due to singing off key and off tempo.

Would you elaborate on how easy it is to accomplish, please?

---Variable clock speed controls during either playback or recording allows
the speed of conversion to be altered to control tempo. To vary pitch
you need to play with the audio waveform in real-time. Frequency
conversion up/down allows the pitch to be altered. Use both and you can
have Frank singing My Way in Mickey's voice with the song playing at the
original speed. Or you can have Franks voice stretching the song out a
couple minutes. Take a loot at a modern mixer panel and you will find
lot's of toys to "shape" the tone and tempo of the inputs and allow
everything to work.
Even a SoundBlaster card has the parts and software to handle it. Take a
look at the environmental sound adjustments sometime.
