Joule Thief

[Artic_Knight]

please note the two experiments posted previously will not work, the double coil in parellel does not build up any kind of magnetic current in itself to oscilate and adding a cap to the second coil does not help matters. the transistor is required for oscilation.

i have tried several experiments and they simply leave me asking more questions.
below you will find 2 pictures, the top is where i placed a cap accross the coils with the positive of the cap at the collector of the transistor. this lowered my MA draw by half but had the same effect on light output!  i would imagine this leaves the cap fighting against the curcuit but then why does it reduce current?

the second photo is where i have been viewing the cap and resistor in parellel and when seing this i had to ask, how does the cap discharge? the way its positioned would allow the cap to charge but there is no return flow unless the resistor is added in parellel and then the cap energy is wasted! the cap will simply discharge through the resistor back to the other end of the cap essentially doing nothing to the curcuit except providing another way to allow electricity to flow in parellel to the resistor, in this case effectively lowering resistance to the base. so i looked and realized allow the current to flow back and it should work rather well. well it didnt. this is a dissapointment as it didnt make sense to me.

at this time i realize i have not attempted 2 experiments i should have IE the negative of the cap on the top picture is on the base of the transistor, what about positive on the base of the transisor?

the second experiment that needs to be tested is when the cap is allowed to charge to base it is allowed to have its discharge source from the negative pole of the battery. i will try to find a way to isolate it within the coils to amplify the signal.

so far allowing the cap to try and perform duel functions of powering the base of the transister while charging then discharge to the coils amplifying the magnetic current has been a failure but this option should be explored for as you can assume the most effeciency comes when you can have items serve a duel purpose simultaneously.

i do not know if it has been tried already however this curcuit appears to draw all of its work off of the coil attached to the collector of the transistor, if this is the case then the coil attached to the base of the transistor should be eliminated and the curcuit could be modified further, i have yet to work out anthing in response to this but simply have a capacitor connect to the positive of the battery and the base of the transistor, have a coil would around the torried going to the collector and when the cap becomes charged it should aid the coil in producing the work needed, however the collector of the transistor will need to be connected to base to allow the cap to properly discharge and utilize the single coil twice.  this may build up enough magnetic current to light the led and reduce resistance and draw from the battery. 

further tests on this will be conducted.

a capacitor in parallel stop AC current and allow just DC to pass.
well, only small ripples of the AC current will be visible.
this is call decoupling
http://en.wikipedia.org/wiki/Decoupling_capacitor

in series a capacitor is doing the reverse.
it allow AC to pass, but prevent DC currents to pass trough.

@ MK1:

Great new designs there.  Excellent graphics too.

@ All:

Here is another video:

Some of you may be interested in this.  I am replicating Jonnydavro's No Bearing Single Magnet Bedini Motor. I have not attempted to run this from the Joule Thief circuit but Jonny says it should.  I will give it a go.

@electricme

Yes it works great Today I plan on rewinding the large toroid having 4 small pickup coils and one very large one for the feed back into the main power system. I feel that I should get up to around 50v when I rectify the main pickup coil.

@ALL

I believe I read somewhere perhaps on here that you can take a toroid and apply ac voltage to the primary coil and then wind a secondary on the toroid to power something else. And that if it worked the device would have no effect on the main device or draw anymore power then what is being used to power the main AC device.

I tested the idea and it works! Below are some pics form this mornings experiment. I have also started to add this to my fuji mod as well. My fuji circuit has around 230v AC and once I figure out how to add the concept to that I will post my schematics!

You could add a toroid with a pickup coil to any AC device and get energy from the magnetic filed I do not know if this is free energy but it is there and it shows no more draw with the toroid in place.

I am not sure who's idea this was or where I first read the plans but as soon as I find out I will give a link.

Take Care,
