Hello friends. I wanted to present my replica of Andrei Melnichenko's GLED device.
I did it according to the original diagram as in the photo.
I followed Chris' diagram and instructions
I wound the core as shown in the drawing and added copper tape screens.
I got the following results. System power supply 2.74V, current 43mA
I received the impulses on a blue sine wave in accordance with the recommendations of the author of the project, but the frequency of 52hz is too low, so the system does not work independently.
I decided to use the LC calculator to calculate the 269 Hz resonance.
Substituting the data regarding the coil and frequency, it turned out that instead of 100uf I had to use a capacitor with a capacity of about 6.8uf.
I have marked all the changes I made in the diagram below.
Thanks to these modifications, I managed to get closer to the frequency of 269 Hz (blue trace).
I recorded a short video showing how the system works. Unfortunately, the system still does not work independently. I've reached the point where someone can advise me which direction I should go, what to change, hmm... My core is SIEMENS AL-6500. Primary winding 27 mH and secondary winding 54 mH, system supply voltage 2.71 V, current consumption approximately 19 mA. What do I need to focus on now to avoid mistakes? Regards
Grzegorz
