Hi Dri0m. Can this wireless energy transmission device send also radio wave signals? Like for example in the source/primary there is a radio or mp3 player and on the receiver/secondary there is a speaker, is it possible to send wireless energy unto to the speaker to work and also a radio wave signals for it to play music from mp3 player or radio? Thanks.

@atayawa69 this device is making its own stable frequency, so i think no. Use google and find some schematic... and broadcasting your own things on public radio range is illegal (i don´t know if it´s illegal everywhere, check it on google)

Thanks Dri0m, I assembled it and got it to work. However, I would like to ask. How come I cannot power a small dynamo motor? Is the output in AC? By the way I am using an AC to DC transformer with 9V and 100mA. And last question is there a way to improve the range and distance? The farthest that I did was at 20cm. Once again Thanks Dri0m!

@atayawa69 the only way how to increase range is increase voltage and coils, and the output inducted on wireless coil is AC, just put there rectifier :)

Can u send me a picture of the circuit u built if thats not too much for u because I am doing this for school project and its due soon

[Dri0m]

@mayurpatel105 that circuit on video is in trash, i burned it :D

Thanks for the circuit idea; I had been trying to transmit the AC from standard domestic power. I did not scarcely consider a self-resonating oscillator and a DC power source instead.

@Dri0m Thanks for the quick reply. Is it also possible to increase the range by putting a joule thief on the receiver side?

that is so cool. this is the only video with DIY wireless energy that i could find! thank you so much!

Hey what kind of battery are you using and what is that thing in the middle of the video when it says "Energy Consumption 20 - 30 mA" Is it an oscillator.
