Slayer's new circuit replication

@Slayer & All
I replicated the new Slayer circuit and made a video of it. It is a very interesting circuit and more tests needs to be run to see if we are gaining anything but ----- It really does charges up the second battery quite nicely.
Well done my friend.

The improvement in results was extremely clear compared to my TIP 31C - Its why i just had to tell everyone. With the new MOSFET I can easily get 2 big CFLs lit at some distance (using 1AA)....even 3, but not fully lit. I'll take a photo of the transistor and hopefully you guys can see what it is on closer inspection.

@ Slayer.

Fantastic progress. I also cant wait to replicate. Just not sure where your charge battery sits in relation to the source battery (emergency charger) - Is it just between the negative side of the charger and the emitter?? Do you use an AV plug connected to either battery??

Hello Seth

No Av plug.The emitter is connected to the positive side of the charge battery.Then the negative side of the charge battery is connected to the negative side of the source.

I think maybe the problem with the IRF530 is the very low on resistance. When it turns on it is like putting a short across the battery and the battery voltage drops to almost zero. The IRF530 will not work with such a low Vds. The IRF730 has a 1 ohm on resistance. Maybe that is why it works.

Thanks, for the info. I used my converted computer power supply for the test. The supply out for the +5 rail says output 30A. Hmm probably why.

@ Seth & Jiffycoil

I tried the IRF530 at 1.5 volts and with a cell phone charger (5.5 volts) with no success. It has not burned out as it should be able to handle much more current than I am using. At 5.5 volts it draws the max current the cell phone charger can supply (187 ma). At 1.5 volts it will not turn on (draws 0 mA).

@Seth
I tried it at 5 volts. I'll try again using a AA. I can clearly see it works for you and the range of field is large, I would love to make this work.

I tested a IRFZ44 which is in the same group as the Z30 and it fried no output during test. I tested the IRF530 same result. I'll wait for the other FETs to come in before I release anymore Djinn from their silicon houses.

Maybe they only like really low voltage input?? Did they fry on 1AA?

@ Jiffycoil & Seth

There is an IRF9Z30 but it is a p-channel where as IRF730 is an n-channel. I will try an IRF530 and see what happens. If it works this should be a big improvement in performance at 1.5 volts since the on resistance is only 0.16 ohms.

I'll add a few of each on my next order and then we can see which it is.

Seth IRF730 circuit?

YEP!!!!

as i said before IRF 730 or IRF Z30....Its not easy to ead as the monitor was quite old.

Seth IRF730 circuit?

@Slayer007
Thank you sir.

@Seth
Your finding is very interesting. Can you show how you have your "magic transistor" wired. Also have you been able to discern the model clearly yet.

[slayer007]

@ CosmicFarmer
Thanks I will do a long term test.

@ Dragon

The meter is a Craftsman pocket meter 82351.

The charge battery does change the input voltage a little.
But there is very little difference in light output.

Also using over 1.2v you will not see much of a difference in light output while adjusting the variable capacitor.
But you will see a big difference in the charge rate of your charge battery.
So adjust the variable capacitor for the best charge rate of your charge battery.

Here is the ciruit I used in the last video.

People with HHO cells could also try the cell inplace of the charge battery.
