you could also youse high signal npn...for example 2N5302...your 555 timer output frequency is about 25 KHz....freat thing man....and try with 12 V so you could have longer range...and about heating...put some condenser or fan and no prob...GREAT VIDEO....
hey man I have decided to do wireless electricity for my physics EEI and need a little help building this thing, could you give us a few tips on what things you need to build this and how its built, thanks.
i really like this project! Great job man. But i have a question or two: how do you know what frequency the 555-timer puts out? How did you know how many turns each throwie-coil has (the secondary coils) to match the frequency. Does it matter that much, or does it only matter when you want to be extremely efficient?? Thanks for the vid and any help you can send my way. -Joe
Hey Joe, The frequency of the 555 timer was set to approximate the frequency that the transformer normally uses in a computer monitor. I did this by connecting a piezo speaker to the output (pin 3) to ground. Then I tuned it till "sounded" like i had just turned a monitor/tv on. It really isn't critical though.
There is no matching of frequency on the throwie coil. Just 20-30 turns on a ferrite rod and your good to go. More turns = higher voltage. A ferrite core on the throwie helps couple the power better, but one the squarish green led throwie in the video has no core at all, and still works.
No. You need an alternating magnetic field to couple to another electromagnet. They form an air-core transformer. DC current only will generate a static magnetic field, and no energy will be coupled. The power supply creates an alternating magnetic field by rapidly turning the transistor on an off.
I want this video on my R230 phone.

Why do people put this annoying song on thier videos!? I wish this song could be blocked!

amazing! i love how theyre all unique, like little steampunk characters or something.
looking at your schematic, you should probably have a flyback diode across the coil?

Hi what are the requirements for building this project. I have couple of wires and 12v battery. Will it be helpful to create wireless energy.

@mindtomachine it its around 25 KHz.

Would 9 volts as input into the driver circuit also work? ( since it works on 5v and 12v )
Scrixx 2 years ago
Would it be possible to change the driver so that it uses 3v button cell batteries?

For the power supply, could I attach a capacitor connected to a inductor? The inductor would produce an AC magnetic field then?
Scrixx 2 years ago
this isnt a trowie anymore
becaus it does not light up when you trow it.
this are led coils
robot797 2 years ago
@robot797 If you use an super capacitor (around .5 Farad) the LED will stay lit for a considerable time after it is removed from the coil.

then it is a trowie
but a verry expencive 1
the trowies are ment to trow away

Is it possible to just run 5v DC into a coil for the power supply?
I'm having trouble understanding the power supply schematic but I can follow the throwies schematics.
If you have time could you explain the schematic for the power supply and/or show how it connects together? But thanks for the schematics :D

Oh I see
Could you explain how to put together the power supply? I'm confused as to how the wires connect and what parts to use..
Scrixx 2 years ago
@mindtomachine so its being used as an oscillator ?

Schematics available, check the description for the link.

I'll work on getting one up on my website. The source power is DC current to the chopper circuit.
mindtomachine 2 years ago
Could you please make a schematic of one of the throwies? Checked the site but it doesn't have the schematic for these =/
Also does the source use AC or DC current?

Dude, thats friggin awesome! Nice work =D, btw whats the sound track your using? Thanks ~Yoko
