Kapanadze Cousin - DALLY FREE ENERGY

Nick,

It looks like your 100w bulb is not lit to more than 50w output or so. Is this the case? And how many of those bulbs could be lit?

I don't know, it was just an indicator of resonance using that one bulb.

You mentioned that the duty cycle was not able to be controlled on that board. No duty cycle then?

The little board has a fixed duty cycle on both channels, something like 40%, see my video at the 1 min.  mark.
Probably you could change that by using a potmeter instead of a fixed smd resistor which is in now, like i did with the frequency pot.

Remember when I asked you about making a Kacher driver using the IRFP260N fets, and the TL 494 board? 

Yes i remember, and i told you that you probably could use a PWM to drive the Kacher, but it would still resonante at 1 specific frequency, see here:

"Perhaps you can drive the kacher transistor with a PWM, but it still will only effectively oscillate at its secondary coil natural frequency with the risk to destroy the PWM."

Impressive sparks indeed in that video you linked.

Ok Guys, giving a second thought- If we need to keep a resonance on the yoke ,which will change with every additional load or hand nearby of the coils, It looks to me it is better to use something more advanced (and still cheap enough)  I have several possibilities - On the picture is what I have at the hand. I think I will go with the combination of Arduino and AD9850- which offer two channels of frequencies up to high megahertz range. But the main advantage is it is easily programmable and fully versatile. In other words, it will also keep an eye on synchronization.

Other option would be to use Rapsberry , but I have for that device a bit different plan. So I think the Arduino is the way to go. And it is still all together up to €20

My question is to make a good and safe driver with power Mosfets.  I will make a PCB later today- just I am not sure what schematic to go with. Do you have some simple one at the hand to share here?  The main components I have at the hand are MCP1407-E/P  MOSFET DRIVER  or  IR2153DPBF and to protect a mosfet I have a choice of UF & Zenner diodes and some varistors.

My plan is to- 1.  connect the grenade coil to earth and find its resonant peaks at low frequency range.( standing wve Ruslan tolked about? )   2. Than I will tune the LC current coil to that requency (by value of capacitor). 3. Than, Tesla tuned to the resonant requency.  - so, at the end all system shoud vibrate like a dildo




Thank you your for advice.

  Itsu and All:
  Yes, impressive spark. But, the lack of a control-able duty cycle is unfortunate.
Maybe the 40% fixed duty cycle will do.
  What one needs to know is just how to connect the TL board up to the fet driver circuit, as well as the fet snubber circuit. As this all may be more complicated than it looks.
  Also, which fet driver circuit to use, and which is the simplest snubber circuit that can be used, as well.
  Any one up for making a diagram? Hand drawn perhaps...
 
  EDIT: Thanks Verpies, for the modified schematic,  that's a good start.

You do not need any programming and microcontrollers to achieve such LC resonance tracking.
A 74HC4046 chip and some AD8032 rail-to-rail op amps are enough ...in addition to an executive section composed of MOSFETs with some suitable gate drivers.

Ask Itsu to show you how this works.  His version might use a FG working as a VCO, but you can always use the VCO inside the 74HC4046 chip, instead.
