Hi Lidmotor,

Thanks for showing the test with the new LED type you found, very good.  This test shows
that the brightness depends only on the RF voltage amplitude a "good" type LED is fed with
capacitively via its back plate from a resonant coil.  Tests done on the other forum also show
that a 'magic' frequency (like 13.5 MHz or so) is not needed, and also the Doc's CREE type LED board
has no special property for the effect.


Dear erfandl and lidmotor:

Please restrict the pixel number for your uploaded pictures to a maximum of 900 pixels horizontally because anything higher
than that like 1280 or 2592 you both uploded recently makes the thread extremely wide and difficult to read.
This is why we need scroll horizontally back and forth to be abloe to read some posts.
High vertical pixel numbers cause no problem, only the horizontal ones. You can use a simple picture editor like Windows Paint
 to resize the wider than 900 pixel pictures. Unfortunately, you need to edit your post within 12 hours after posting
because forum software does not let modifying posts after the 12 hours passes.
So in the future please consider this when uploading higher resolution pictures.

A frequency tunable exciter

A 50 turn Dr. Stiffler type L3 was made on 1/2" PVC pipe. It worked fine as a Slayer
Exciter, with a 24 turn same gauge primary. Frequency was 21MHz.
Next, 5 more turns were added and the result was a decrease to 17MHz.
Aha, so it's just like a Crystal Radio and the tuning...more turns for a lower frequency.

Using an 80 turn Dr. Stiffler like coil as the movable section and keeping the primary from
moving instead, the coil can be moved left and right to run from ~9Mhz to ~17MHz.
That also includes the 13.6MHz
I had thought that all we were doing with the primaries on Slayer type circuits, was
tuning for most efficiency and best wireless output.
Perhaps driving it at 20V is as easy as running a Chinese booster circuit in front and using
a TIP122 or 2N3055 as the Slayer transistor. This one is using a 2N3904.

Here's the vid:

Now you can make a proper tuned-circuit receiver and do away with the single wire connection, and light your LED wirelessly.

Hi all, i noticed some post directed towards me, I will read them shortly, though just wanted to share a short video showing the setup as it is now.
I raised the voltage to 16 volts for a more light output and have 4 parallelled sets of 1n4148 diodes in series as the av plug.
The input is now 21 milliamps at 15.98 volts or 336 milliwatts.
The brightness is impressive, though still bloomed a little in the video, thought a video would help reduce that, guess not.
In my many light experiments, I've yet to see this kind of light output for such a low input power.
I'm still sticking to the more copper mass primary is of benefit story. 8)

TK---do you remember back about 4 years ago you did something like this and it inspire me to try it?  Here is the video of it from 2014.  I used a tunable inductor instead of the capacitor but it is the same tank circuit receiver idea.  What comes around goes around.  I still have that thing and I've been playing around with it on this project.  Here is my little creation from 2014:  https://www.youtube.com/watch?v=fOkkF4pr23s

  Here is your 2014 video that inspired me.  It is totally applicable to what we are doing here:  https://www.youtube.com/watch?v=80D92QaOcM4

PS --Thanks Gyula for the tips on posting size issue.  I will work on it when I figure out how to do it. Ha

Hi SkyWatcher,

Okay on your  "sticking to the more copper mass primary is of benefit story",  that is fine with me.  8)
What comes from my previous post to you on the primary coil having about 0.69 Ohm resistance (as per my calculation) is that to reduce the loss in this coil, the solution invariably involves increasing the copper mass by using thicker wire for it.   ;)

Using thicker than AWG 24 wire or using several wires in parallel as you have done so recently in the René charger tests invariably involves using more mass:  the goal is to reduce DC resistance to as a low value as possible and practical, well below 0.69 Ohm.
 This tendency is to be observed for the resonant secondary coil too but obviously the mechanical size limitations bring trade-offs in the quest.

Hi Lidmotor,

you wrote
PS -- I will work on it when I figure out how to do it. Ha

Well, by now you cannot do it because the 12 hour long time period available for editing is over for your post with the high resolution picture but here is how to do it, others may also benefit from it.
There is the Modify icon at the upper right corner of your post (you need to log in and also you should be within the 12 hour editing time limit).

You can see these under your post to be modified and just click on the Clear attachment icon to remove the high res picture. Then use a picture editor (like Paint in the Windows) to reduce the number of pixels (Paint has a Resize feature).  When your picture has the not higher than 900 pixel number horizontally, then save it and attach it again to your post (as the first attachment).   It is unfortunate that the software for this forum has such shortcomings like oversized pictures cause.

TK - with enough smog, that circuit will run inductive loads too...it's the same on the right as the way motors can be driven. Works better than an FWBR with a cap.
One example of a use for everyone in the USA would be 60Hz...your Rigol scope will likely show mains noise whenever no other circuit is running and I think it would be neat to have a situation where that doesn't happen. The smog harvester removing it.
I've no idea how to do the mathematics on that, but the coil would have to be of a high turns number to bring it to that resonance point.
It may work for the UK and other 50Hz countries, as is, don't know yet.
I'd really like to build such a thing.
That would be something to behold, no visible input power but a Cree board is sat there lit up.

   Lidmotor:   Just use paint to resize the image to less than 1500 wide.  That's what I do on Windows 10,  without needing any other photo software.
   I also took apart one of those 40w equivalent, 4w led filament bulbs. But, mine has no led chips, but uses 4 led filaments inside the sealed glass bulb. The bulb itself is longer than the one you have.  And this bulb also works great, running capacitively off of my Kacher circuit, after I gutted it. I'll do a video of it soon. Just need to get the diodes on it, when I have a chance.
  The image below is taken when using a 5w solar panel connected as the input to my Kacher circuit. 12v panel, max 5 watt output.
It gives a LOT OF LIGHT.  Bang for the buck... 

   I'm expecting a 12v to 35v buck converter, so we'll see what that does to the input voltages that can be tried.

Hi Nick,

Unfortunately the less than 1500 wide is not good yet, I tested it and found the 900 pixel as the maximum.
Your above picture has 1000 and it is already wide a little...  8)

   OK, I'll make them smaller yet, like 800 wide, or so.   We need to keep the site working right.   Thanks.   
   BTW:  I can't read the numbers on the crystal, I can see three zereos, 000, at the end, first number has solder on it.
  I an still tryng to find the right bulb with the metal backing, otherwise it won't work, capacitively.I see that building the correct controllable crystal, or other, type of oscillator circuit is essential, as most guys don't have an SG.
  My idea is still to follow the capacitive trail to the source of any anomoly.

Likely a lot of this is about the monitors used.
For example, mine was from a Salvation Army thrift store for $5...IBM ThinkVision 17".
It's square. Many others will have 24" super wides or 3 monitors in a horizontal line and all
that snazzy stuff. Somewhere between will be widescreen laptops and likely phones and tablets.
Browsers will also display differently. Am using Firefox 59.0.2, where 1000px is a touch
wide here too.
The ideal would likely be an image that can be seen, say 640x480 and which would suit all
scenarios, but that can be clicked on for a full sized version.


Am soldering up the AD9850 signal generator today.
The rotary encoder and screen are still on their way, but another encoder has been finally
found and a 1602 screen has been removed from a previous project.
The idea is to run a frequency, any frequency up to 30MHz with the circuit and then see
how simplified circuits such as the tunable exciter setup behave with that same frequency.
The AD9850 is a low output device, but will help with verifications and pointers for
resonant frequencies of coils and loads.

I think Slider posted a link to a good crystal checker and if your crystal oscillates then you can estimate the frequency
from the scope display. See the circuit you could buld with any small signal transistor:
http://jaunty-electronics.com/blog/2012/08/simple-oscillator-as-crystal-tester/   

On the scope you extend the time base to see say 2 full period of the waveform, it makes easier to see and calculate frequency.

Gyula---Thanks for the help on the post size.  I still don't quite understand what is going on. I changed to another computer and on this computer the text at least is the right size.  Can it be a basic setting on the other computer?  I'm very sorry about the oversized posts with the BIG picture.  I will work on this and not post pics until I have the problem solved.  Using paint on the computer will work on the pics but what about the text width?

Thanks,  Lidmotor

P.S. All --  I think this project river is flowing in the right direction even though there are side eddies.  I am anxious to see Slider get his homemade frequency generator up and running.   

Here is a test picture from this computer--

Hi all, Hi gyulasun, thanks for the information.

Yes, that is exactly what i was thinking to try next, is multistrand 24awg. magnet wire primary coil.

I'll try a bifilar 24awg. magnet wire coil with both strands in parallel and use 80 turns again.
The coil will have even more mass now, we shall see how she performs.
peace love light :)

Edit: ok, i just finished winding the new magnet wire coil, it is bifilar 24awg. magnet wire, strands are in parallel at 300 milliohms and 31 grams weight, which includes a little electrical tape, that is used to tighten the windings together.
