DIY inductor coil from compact Fluorescent Light

Hi Friends.
In the present a small electronics invention. Most of these types of switching circuit. is…
An Inductor (or coil) is one device To create problems for me To buy or use. But it is only simply a wire wound into a coil and usually around ferrite core because they have high value and also small. I like to use it.

This is DIY inductor coil from Compact Fluorescent Light. I like free and enjoy creating odd things. A Compact Fluorescent Light Bulb is a device that uses high-frequency switching.So there is coil inside them. Therefore I will keep the Compact Fluorescent Light Bulb burned out. To apply an inductor from them as Figure 1.

Many the compact Fluorescent Light Bulb burned out


Figure 1 Many the compact Fluorescent Light Bulb burned out.

When I make low current and a high-frequency switching circuit. I use a toroidal core that removes from the PCB. As Figure 2.

Remove the coil on toroidal core


Figure 2 Remove the coil on toroidal core (DIY inductor coil)

Suppose that we want to have the coil inductance is 100uH. as The High power 6 LED Flashlight for 1.5V AA battery project.Then we measure the inductance of it. It appears that the value is 200uH. To remove the wire to low as Video below then measure it again.

How to make inductor 100uH

Modify the toroidal coil into 100uH
Finally, we have the induction, according to need is 100uH. as Figure 3

Update: As I use wire 24 AWG turn on a 10mm toroidal coil is 10 times

Measure the inductor as I need


Figure 3 Measure the inductor as I need.

Next, I test it on The High power 6 LED Flashlight for 1.5V AA battery project as Figure 4 it works as well same original parts.

The high power LED flashligh works well


Figure 4 The high power LED flashligh works well.

I hope this way can help you save. And reduce global warming too.

    Greetings, Sir! Your information is very useful and it helps me a lot.
    I want to know Sir what is the wattage of the CFL?

    Hi,
    If I use 2.5mm NYA cable to make an air core coil, is it possible? If possible, how many turn should I apply to make 30A 40uH air core inductor?
    Thanks.

    • Hello Awak Awai,

      Thanks for your visit. This idea is suitable for small circuits. The toroidal coil is small.

      If you use 30A you need to use big wires and core.

      Yes, you can use Air core. and measure it, to check the inductance.

      Thanks
