Alexkor Air Core Coil Radiant Charger

[citfta]

Yes you are missing something. You need to get a basic understanding of electronics before you take on a project like this. The neon is there to protect the transistor from voltage spikes so you don't want to build it without the neon. The other thing is you apparently don't understand is what a diode does. The diode from the neon and transistor connection blocks any back flow from the charging batteries to the primary battery and blocks any reverse flow back to the charging batteries. There are many places online where you can learn the basics of electronics. You wouldn't attempt to make a long trip in a country you have never been to without first learning how to read a map would you?

[doGalot]

Thank you for your advice. I do understand the diode. Just IMHO there would also be one off the coil (horizontal red line) to keep any reverse flow to it. The Patrick Kelly pdf I'm looking at (Chpt 4 - The Alexkor Circuits) mentions the neon isn't needed if the fast-action diode is used. I could add it for safe measures...

BTW - any update on OlTimer and any others? I appreciated reading the updates...

Hi doGalot,

Let's go through the circuit operation and see if that helps you understand why each part is there and what it does. When the power switch is turned on current then can flow from the battery to the coils. At this point the transistor is turned off so no current can flow through the part of the coil marked in red. Current can flow through the blue coil to the base of the transistor. The resistor is there to limit the amount of current that can go to the base so the base of the transistor is not burned out by too much current. When the voltage on the base of the transistor get high enough then current will start to flow from the base of the transistor through the emitter of the transistor and back to the negative of the battery. At the same time current will also begin to flow through the red coil and through the transistor back to the negative of the battery. When that current through the coil get high enough it will override the magnetic field produced by the blue coil and cause that coil to stop conducting. This then causes the transistor to turn off and that stops the current through the red coil. The cycle of on and off repeats many times per second.

When the transistor turns of because of the current being stopped going to the base then the current going through the red coil can no longer get back to the primary battery. An amazing characteristic of a coil is that it resists any change in current going through it. Since the current wants to keep going it will now go to the diode and to the positive side of the batteries being charged. The interesting thing about that current is that it will produce a voltage high enough to get where ever it can go. So we can use a 12 volt battery to charge a 24 volt or even a 48 volt battery. If for some reason the charging batteries got disconnected the voltage would go high enough to force its way through the transistor. This would probably damage the transistor. So the neon is there to give that voltage spike a place to go in case something should become disconnected going to the batteries being charged.

I forgot about the capacitor. But it is really only there to shape the pulse for better signal to the transistor. The circuit will work without it but it is better to have it there.


I hope this has helped some.

Thank you for that explanation. I appreciate the step by step. I look forward to making one of these and try to post updates.

on a side note - could you suggest some projects that I could try that uses Cat-6 cable? I have that and telephone wire I'd like to be useful.

[citfta]

Sorry, I don't know of any projects that use Cat-6 cable. Maybe someone else will have some suggestions.

[doGalot]

I was wondering if they could be used to make coils? Multi-strand of course...

Hi =)
I'm new in this very interesting forum.
Please help, and sorry for my english
Only this thread about "Alexkor" system here?
I have a some questions. In the PJK book, in chapter 7, we can see original scheme with one module (4 diodes). But there are another modified scheme see, where tree modules which contains 12 diodes summary, and one big capacitor C1 100uF 400v. If I put there 20 modules in parallel instead of 3, so what capacitor C1 must be there? 20 modules must give more power I think. Another moment with thyristor and neon tube. They will not die with 20 modules?
Thanks!

Hello greetings
interesting Alexkor projects
How are you doing with your project? What progress have you had?
go ahead and good results appreciate you
Thank you

Greetings SkyWatcher

good presentation of your progress.

As soon as I can build a prototype, for now I am with a generator and anti lenz coils.

but I comment something about charging battery.

A long time ago I built a thief of joules, it fed several LEDs, it served me to read at night.

The thief of joules fed it with a small motor, I put some blades on it, and I adapted it to a fan that I used to cool off at night, the motor served as a generator, which fed the thief of joules, and thus did not use a battery to power the thief of Joules, I turned on the LEDs and had a light, but at the same time I took advantage of the self-induction to charge the battery, charge a typical AAA battery, it was well charged.

In this way do not drain or use another battery to charge and have light.
Since the idea was to take advantage of the wind from the fan by means of a small motor, power the thief of joules to have a light and a charger.

Hi all,

This is my first post to the forum.I am attempting the Alexkor circuit that doGalot is working on. I am very new to electronics and still have a lot to learn about the subject.

I have posted my first attempts at constructing the circuit. I accidentally ordered a very large heat sink for the transistor which is what the large metal object is.

I live off-grid in the UK and am looking for a way to be less reliant on my petrol generator less to charge my batteries. I emailed Patrick Kelly who has been really helpful and has guided me towards the Alexkor circuits as a good beginner's project,

I have had some success with charging but I have not got the two batteries that I am attempting to charge up to a full charge within the 20 hours that they should. My next idea is to lower the resistance to the base of the transistor - by doing this though, I am ignoring the suggested resistance by Alexkor and I do not want to blow the transistor.

I wonder if it would be possible for people to see if I have made any mistakes. If anybody has any suggestions I would be enormously grateful to them..

Best wishes,
Michael

Hi members,

Am not very new on the forum, only been inactive. Am not schooled in electronics, but have been reading for two years; first Patrick J. Kelly's (PJK book) chapter 12, NEETS Modules, Bedini SG, The 3 Handbooks, The Free Energy Secrets of Cold Electricity, The Quantum Key, plus a few sites here and there. Also in the process of building one of Don Smith's Magnetic System.

I have built the Alexco circuit as presented in PJK pdf (downloaded May 2019) book and the first picture at the bottom of the post I am quoting now. I started with a single joule thief on an existing small trafo by using two of the coils. I designated the one with the highest resistance as my collector coli and the lower one for the base. Using 13003 transistor (and 10k var. resistor) also marked TR, 12v input from 2 small solar panels of about 5 watts each on two old car batteries. Circuit outputs 11 - 120v on dailing the var resistor. The Batteries charge up to about 12.5v from the panels and drain quickly with one 5 watt LED light in about 1 - 2 hour ranging.

Been I trying to use it to revive an old UPS bat but the voltage of the circuit drops from 100 to about 55 when I connect the bat. From there, it starts falling slowly. The lowest it has fallen to about 29v. I feared leaving it on the night due to a fire or anything. The next day it starts again at 55v and slowly drops. According to my sound card-based view, the circuit seems to be running at about 20k Hz. The bat started with 400mv, after the night, I found it at 500mv, next about 600mv. (Will post pix later)

What is happening here I need help. Thank you for your help.
