@crazylazystacy In this case it's not important. You can experiment with the number of turns, thickness and diameter and see what is the best setup. (:
@MultiCreek Thank you so much for everything:) if is not to much to ask a step by step video would be great. i know the circuit is simple but it does get tricky it would really clear things for us beginners:) Thank you for everything so far and for posting the circuit diagram a lot people dont show anything.
@9Damjanp No you can't, maybe you can put one with simmilar characteristics, check out transistors datasheet for more info about them. But BD139 is common transistor and you should have no problem getting one...have fun dude ! :D
@MultiCreek If you could make a step by step video, that would be amazing! I've been trying to construct the circuit myself, and I can't get it to work. I don't know what I'm doing wrong. Thanks!!
@MultiCreek If you could put together a 'step by step' video, that would be AMAZING! I've been trying to build the same circuit, but it's not working for me, and I have no idea what I'm doing wrong. Thanks!!
instead of having an LED on one of those receivers, you should try putting a cell phone charger wire on it, and see if you can charge a cell phone wirelessly.... let me know if it works. NICE project by the way :)
@ScrotumlessMonkey n ot, you're mistaked, is perfectly possible to charge an cellphone with this,but is not aproppriate to do this, because you have to put one cable betwen the celphone and the coils,because of this, you have to put the secondary coil in the battery compartiment, and using a diode to prevent the countercurrent, and a capacitor, to prevent a linear wave of energy ( the diode let pass 0,7V of polarization), and other capacitor to make the voltage more stable..
@fss1704 Not really If you can get a stable current of 5V using the changing flux in the magnetic field created by the small solenoid in the 12V circuit and use a 12:5 Transformer or coil it would be able to power a cell phone. As you mentioned a capacitor can make the stable however there will be alot of current lost in the magnetic field and the changing flux field.
@D3mon5lay3r whatever,is not a good idea to make,is perfectly possible to do, but as i have said, is not appropriate, first because this, and second because of the current needed for charge,about 250Ma, and i think thar your device is capable to get about 50Ma,and for this operation if u not put a capacitor, the coils will act as a resistor, and i'm Brazilian, i've the same reaction making my 1st english video because of this the peoples here (as i) have noticed that u aren't "american".THKS.
@Powdermonkey09 Transmission is working on a principle of induction. Transformers work on that principle too. This is still transmission. Deliver current over distance with no wires. That's transmission. Now to principle of transmission is induction, but not every induction is transmisson. :)
did you use any bd139 or is there a special one that you recommend

@dowgaa I don't understand. BD139 is the name of transistor. There are no several tipes of it.

@MultiCreek What is the thickness of the wire. does it make a difference what i use

i found you can do the same without a receiving coil using cement and small aluminum particles

its not powerful enough to use a phone charger. hense the led.

That's really more along the line of what you would call induction not transmission. A transformer functions on the same principal.
