Hey there, so after scouring google and forums alike I finally found a circuit I could easily construct with the parts on hand. First off I was skeptical at first that I would see results, but I did! So as of now I am still playing around with the configurations and such. So you may ask what the hell is this that I am looking at.
Well I will explain my intentions, basically I am trying to capture energy from the air and turn it into something usable. With this circuit I draw in RF from my antenna and through this circuit which charges a capacitor, which in turn stores the energy until I discharge it.
So I have been playing around with this circuit for quite some time and I will update this blog when I sit down and do time studies on the effectiveness of the circuit, but to keep it short and sweet my quick answer is yes it does work and I am able to not only charge the capacitor but I am also able to power a 5volt led.
How Does This Work?
This is the circuit I have used for this build,I am unsure of its name, but I do believe it is a Tesla patent
combined with a "Joule Thief", The positive and negative connections of joule thief connect to the positive n negative on the "Tesla" circuit.
Results?:
So far I am capable of charging the capacitor and lighting this led. It is briefly but it is proof of concept for small scale applications. With my lack of parts or even knowledge this will be something I research a little more. With a better antenna and bigger capacitors or even supercapitors I believe I will be able to produce greater results.
I can say roughly in say 2hrs I can flash a 5 volt led
Any ideas or suggestions are greatly appreciated, I would like to learn more about super capacitors and the capabilities.
Hey there, just a quick little snippet of a cool coil and its abilities. This is fairly simple to build and really cool to play around with. The coil is being powered by a 1.5 volt battery and can go upwards of 9 volts..... 12volts and things start smoking lol, make sure you use appropriate resistors
This was a super simple build, which me and my lil guy threw together on a past weekend, it runs off an arduino which is then powered by a 9 volt battery, Eight different coloured leds were used as well as eight glue sticks to add in the cool effects. As well I have added a 10k pot which allows adjustment for the speed of flash.
Code: The sketch is very simple you can either just google it, write it, or just copy and paste you lazy bastard u.
// 8 LED's are connected to the 8 Pins of Arduino
// with a series resistor with each LED
// Potentiometer is Connected to Analog Input pin A0
// refer circuit diagram for reference
// You can Change chaser speed by varying the pot
int led1 = 1;
int led2 = 2;
int led3 = 3;
int led4 = 4;
int led5 = 8;
int led6 = 9;
int led7 = 10;
int led8 = 11;
int count = 1;
void setup()
{
// put your setup code here, to run once:
pinMode(1,OUTPUT);
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
pinMode(8,OUTPUT);
}
void loop()
{
// i reads the analog pot value connected to A0 pin
// this value changes from 0 - 1023 giving us a delay of
// 0 to 1023 milliseconds
// count variable carries the number of LED pin
// we reset the count to 1 when it becomes more than 8
A joule thief is a self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads. This circuit is also known by other names such as joule ringer or blocking oscillator.
It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"); hence the name, which suggests the notion that the circuit is stealing energy or "joules" from the source. The term is a pun on the expression "jewel thief": one who steals jewelry or gemstones.
The circuit is a variant of theblocking oscillatorthat forms an unregulated voltage boost converter. The output voltage is increased at the expense of higher current draw on the input, but the integrated (average) current of the output is lowered and brightness of a luminescence decreased.
I have been playing around with this circuit for quite some time and I am very interested in it's applications, it is very simple to build and quite pleasant to watch the results.
Follow these instructions in order to build your own version, later on I will show you some cool experiments I have been working on, using a joule thief plus crystal radio, as well as a joule thief combined with another cool circuit that for the life of me I forget the name, but I came across it while researching Tesla cosmic energy collector. Basically this circuit allows current to be collected from an antenna and it runs forward using diodes and is ran into a capacitor which stores the charge. I have been quite successful in lighting leds.
