  • Could you have just used the second wire on the speaker wire coil as the secondary (pickup coil)?

    Cheers and thanks for posting this series

  • @IsItTrue99

    Yes you could but it may not be the most efficient way to extract the energy. One would be best to experiment to find the ideal tuned receiver.

  • hi there..this video was amazing. i am working on a wireless power transfer project..just several question though. if i am using a normal copper wire instead of using the audio cable would it work?another question is what type of capacitor that you used in this test??can u give in detail of the capacitor that you used...it would really be helpfull

  • @healtybiotic

    It will work with normal wire also. Capacitor used are non polarized since the input is AC. It was a ceramic capacitor in the Pico Farad range.

    All the best in your experiments.

  • You are a star ,, this series of videos is the best explained I've seen ,, I've got lots of electronics stuff but i struggle with theorys ,, this helped clear it up loads .. 5/5 !

  • Hi ZED74,

    glad it can help. Thanks for posting your appreciation.

    Luc

see all

  • after fiddling about with this setup I realised i ddnt have a large enough inductor to light a neon ,, i could get it to strike sometimes but that was only by flicking through the ranges on the frequency generator ... I also realised a good easy way to fine tune it though ,, I just put a multimeter across the neon to find peak voltage :) I was only getting up to 58 volts with my coil ..

  • The only thing I see here is you showing how resonance bypasses certain parts of the cicuit. The bulb is not an effective way to show anything but the action of resonance bypassing it. In order for you to show anything real you need to measure the input from the source and the output from the endpoint. Everything in between is acually becomming a perfect conductor and not showing anything being used. The energy is still comming from the source signal gen but only showing at the end.

  • wow man you mean the energy is from atmosphere? i have heard of people putting devices under power lines and tapping huge amounts from them. just cause the coil is receiving a tiny input it actually amplifies the input at resonance? is this radiant energy? i have never seen an active example of overunity. thanks
