You can make a simple generator from household things. This generator is so simple that you do not need commutator. The electrical energy from the generator is directly attached to the lamp. Lights will keep turned on in a stable and appropriate voltage.
The things that you need to be prepared are:
Drill Electric
- a nail 8cm
- 100 grams of 0.1mm wire (maximum size)
- A bulb/LED lights 1,5 Volt /25mA
- Used box ( Plexiglas or cardboard), measured 30cm x 8cm
- 4 magnets (5cm x 2cm x 1cm)
- A roll of tape to cover the wire
- Sandpaper
- A small electric drill to rotate its rotor (optional)
Warning:
Keep out your magnet of all electronic equipment (PC, Hand-phone, Television, credit cards, etc) to prevent them from any impact of the magnet.
The first step that you need to do is start to make a box out of a Plexiglas or cardboard. You should be measured them by 8cm x 8cm, 8cm x 3.5cm, 8cm x 8cm, 8cm x 3cm, 8cm x 7.5cm. The wire should be placed as close as possible to the magnet to get maximum results. You should also measure the magnet properly. Pierce the nail on the center line of the box till translucent canopy. Make the hole as fit as possible. Do not make an over-sized hole; just make sure that the nail has enough space to rotate. Do not for get to remove the back nail.
Take 10cm wire email tape the wire in the middle of the box then start rolling. Roll the wire from the middle and take it down or up then rose again to above/below, and so on. For the remaining 10cm wire you can also put it in the middle position. It does not matter if the nail hole is closed. Wrap the roll with the tape while holding the end of the wire but do not wrap the nail hole. Clear the yellow coating (2 cm or more) using sandpaper. Stretch the wire carefully to put the nail in the hole.
Make 2 pairs of magnets, stick them on each pair. Stick them on a nail in the box, extend it laterally (cross-shaped). Adjust the position of the magnets to be exactly same and balance. Try to rotate the nail to make it sure that the nail spins freely. You can tape the magnet so it will not fall from the nail.
Make sure that the tip of the wire has been cleaned out from its coat so that the electric current can turn on the lamps better. The last step is you need to connect the wire from the generator to the lamp. Make sure you have separates the wire to avoid short circuit.
