Magic Candle With a Kinetic Electric Generator (Fusion 360)

This lamp with a kinetic generator that lights up when shaking.

This generator can be used in the Internet of things, as the charger or as a basis for a flashlight.

I used this generator in the magic lamp for a children's holiday.

I created this lamp for a little grandson who got a magic candle and he was the best gnome on New Year's holidays!

The body lamp and candle body I printed on the 3D printer.

I decorated the seams and joints with a 3d pen .

For the generator should be -
- 4 magnets Ø 15 mm x 5 mm

- 6 coils on a common basis

- 12 diodes Schottky

- 1 bright white LED

- 1 thin magnetic disk.

The body lamp, I drew in Autodesk 123D Design and consists of several parts.

Lamp housing is easy to assemble. I used a bit of glue.

You can see the photos part of the body and when it is assembled together.

Lamp housing printed with wooden filament. STL files attached.

The body of the candle, I drew in the Fusion 360.

As the drawing you can see in the video.

It's an easy job, and did not require a lot of time.

The body of the candle, I printed with white ABS plastic and yellow flame.

Inside the candle is a space for the generator.

STL files attached.

• I printed a base for the coil. The magnets are moved inside the base.

• I reeled 6 coils on a plastic body. I used 35AWG wire (0.143 mm) to fill. Each 2 coils connected to each other as shown. Thus we get the 6 wires.

• Next, we collect 3 diode bridges and connect to the coils. The positive and negative terminals are connected to the LED.

I used PMEG2010AEB diodes as the best for this purpose. You can use other Schottky diodes with low forward voltage.

• Insert the magnets. I used 4 magnets diameter 15mm and 5mm height.

You can use any of the magnets 15 mm diameter of several pieces in such a way that would have been the height of 15-25mm. You can also use single magnets 20-25mm.

• At the bottom of the candle we sticking a small magnet that will be as a spring.
  

If everything is correctly assembled candle should flash at easy shaking.
