now those are some powerfull words there grumpy



espicialy when  you hook up a diode and a cap

@ All

I have a little bit of good news this evening.  I received by mail everything I have been waiting on, both from Radio Shack with my 3904 transistors (4 of them), and from UPS with my crystals, adjustable capacitors, gemanium diodes and a few other goodies.  I also purchased today from Lowe's, some floral wire.  It is either zinc or iron with a green coating.  Perfect for wrapping a toroid!   

Radio shack replaced their MSR3904 with the 2N3904.  Stock number 276-2016.  Well, this transistor had worked the best with my old setup before I burned it up.  I tried it with this new set up and just completed the test.  New BEST time:  38 minutes 15 seconds

Details:
Collector-Base Voltage VCBO 60 V
Collector-Emitter Voltage VCEO 40 V
Emitter-Base Voltage VEBO 6 V
Collector Current IC 200 mA
Base Current IB 50 mA
Collector Power
Dissipation
Ta=25
PC
625 mW
Tc=25 1.5 W
Junction Temperature Tj 150
Storage Temperature Range Tstg -55 150

I will be rewinding my barium ferrite coil core tonight.  I then have a couple of experiments in mind.  I will let you know if anything interesting turns up, tonight. 

Holiday Cheers,
Bruce

Nature has its own type of electronics or your brain would not function and your heart would not beat. I know what you mean though.

The transistor is a good thing in that it permits some type of control, but the downside is it does not permit flyback to return back to source or the void. That damn diode. There's no turning back.

All Tesla had was commutators, slow. medium and fast rotations and Caps freak galore.

Macedonia has a BUZZ11 or something diode that comes from computer power supplies. You should look it up. I think his circuit permitted a cap recharge every 10 seconds or so. Search Macedonia CD.

Honk has the tech savvy to push, then slide to recapture, push, then slide again. Sort of like a three step. Hope his next circuit works on Jacks device. So do some of the RV guys who are starting to capture the drive motor flyback to re-charge batteries.

Most of the EEers here have not really delved in circuits that require a 4 step or more logical sequence. Most projects are linear based design. Put in the orange, get out the juice. Not enough juice? Ram in more oranges. Most have not used Teslas method of actually juggling the fields, swooshing them out, capturing them back. Thinking of the entire system as a loop.

SM's system is a loop. This circuit is a loop, although somewhat aloof.

Once we know where and when the flyback is generated and how to capture it and then how to put it back into the system, this loop will be less aloof.

I think one of the main hold backs is we are trying to do this with very low voltages and the coils are hogging it up and the transistors have a power dissipation rating that is self explanatory, plus resistors always cost a few watts here and there. If you simply pull out the transistor, does the led still light? What if we started to up the anti. Larger coils, real f*&?k&n 12V bulbs instead of these furty LEDS. Some nicer sized caps, more meat. Something I can put my DC clamp-on ammeter around.

I just got this transistor that's in a metal cylinder. Supposed to handle a little more "juice". Did I say that? Here we go again. lol

Keep on pushin guys. My current ferrites are the sh*ts. I'm winding a dual bifilar mobius coil on some iron.

I was thinking about reversible effects.  I stuck an LED under a bright light and measured voltage!  So I'm wondering whether running the TPU under bright sunlight will show a different run time vs in a dark box.
