Hello,
Just a wireless power transfer with a couple of 0,50 mm wires.
First having square wave from 555 and flipping it with LM358N this 16 V. 800 mA. max. power.
On the transferred site, again a LM358N OpAmp to create a square wave and boosting the voltage. The result is approximately 310 mA with 9 V. on the green 4.21mH coil.
The purpose is to use the green 4.21 mH coil as a magnet, it becomes an electro-magnet but the power is not enough.
Actually there are 12 of these coils in series.
Any advice ?
(All the coils are made of 0,50 mm. coppers. Inductance values are estimated.)
