hooked up the last unit i made and im not sure if it makes a diff at first glance i wired it up many ways and found it does work the same as just the jt but i can use steel as out or copper or both so as i think i tryed both seperatly but not both at the same time


if you hook it up backwards it will not lite at all if you dont feed out of the tranny through it  agin no action ...


but what i was thinking dont know if it will work or not right now but was to feed the steel/ copper collector wind with its own source... and see if it will make a diff  the jt running on top of a coil altho now i should be able to wind secondaries off the jt  with the air core i cant unless they are identical to the jt in mass i may try that too down the road ..

ist!

Topic = Trying not to replicate the mistakes of others.

OK here is my 2 c worth, I hope you will understand my reasons.

We are al human, and automaticly make mistakes, the JT forum is filled with posters making mistakes, (me also) and when they are discovered, the correct answer is forth coming. But, some of us need to make mistakes so when this happens, we learn better.
If someone said, if you put a 6v filament bulb on a 12v battery, it will blow the bulb, thats right, but if you want to actually see this happen, DO IT, observe what occurs, take a voltage reading, amperage current draw. See how bright it gets to the point it blows.
The bulb blows, it's done its job, time to take it apart and see how it was made etc etc, one learns more.

If a new forum member reading this wants to make a mistake, go for it, then gets the JT to work, he learnt more in the process than it working from the start. (I getting my words mixed up again)

But, there is also the person who already knows what to expect if he connects a transister up wrong, da smooooke comes out and once the smooooke comes out, it dosent work any more ha ha.

I guess what I'm saying is, it really dosent matter at all, if one wants to make a mistake or dosent want to make a mistake.
Its a personal choice, but it is better on the hippocket if no mistakes were made.

@ Jim:

Have any of the mice made any mistakes lately?  I got $10 riding on the peanut butter.  Good to hear from you.

Topic = Iron coils instead of using a Torid or Transformer with copper wire windings.

Hoo boy, here I go (might be a big mistake lol)

I have a theory which I have PM a couple of people about, but not had any replies.

We are trying to create a magnetic field in a torid, then trying to capture this magnetic field to do stuff with, lighting LEDS etc etc

Someone posted above, he hasn't seen anything new since the first 20 posts, ok here is something new, which relates back to NS.

Get some IRON wire that is insulated, or put some insulation on the iron wire.
Wind a coil with this insulated wire, on a toilet roll, dont use a torid or iron laminations, just make a aircoil.

Whats occurs is this, when power is applied to the coil, the iron wire itself becomes its own magnet.
As we know, as the circuit is broken, the magnetic field collapses, this induces a high voltage pulse inside the same coil which created the magnetic field.

Use a HALL EFFECT Transistor, which can sence the magnetic field and switch off the juce to the coil.

T block the pulse going back through the circuit, put a 1n4004 diode between the bat and the switch.
Using a second diode of sufficient rating, the HVP could be directed via different path, measured with an instrument, rectified, fed to a capacitor etc etc.

astable multivibrator , i think this is a 555 way start .http://delabs-circuits.com/cirdir/theory/gates/doc00019.html


@Electricme

It sound real nice keep it up!
