A basic bicycle generator can be a really simple and fun project for newcomers and amateurs to the world of electronics and inventions. In this article, we will describe two different types of generators. The first one is for a pedal bike. It can be mounted onto the bike wherever you go. The other is for a stationary bike. With this one, you can easily charge a battery or power a small TV.
Acquire a Motor – The first step is to acquire a DC motor for bicycle generator. This can be acquired from an old computer or printer. Motors are present in almost every electronic item. You can even go online and buy a new motor at an affordable price. Once you have acquired or bought a motor, you need to take off o-rings and plastic gears.
Mount the Motor – The next step is to mount the motor onto the back tire of the bicycle. This will allow the tire to turn the shaft of the motor. You will also need to put a sort of disc to the arm of this motor. This will allow it to touch the tire. It is always better to use big rubber discs as they provide good friction. The turning will cause voltage to easily come across the leads on this motor.
Basic Procedure for A Stationary Bicycle – First, let us talk about a stationary bicycle. If you are trying to build a stationary bicycle generator, you will have to build a stand too. This will make sure that your back tire is elevated. You should use a multimeter or voltmeter to measure the voltage your motor is producing when you are pedaling. Usually, this will be enough to power a small TV or charge a 12 volt battery.
The next step is to attach a voltage regulator to the leads of the motor, reaching whatever equipment you want to charge or run. If you don’t use a regulator, batteries can explode. For those of you who don’t know, voltage regulators are small chips. They can be easily soldered onto a circuit. It is quite simple and easy to acquire a schematic for every voltage regulator. You can get them at an electronics store or online.
Once you have used a voltage regulator with motor for bicycle generator, you can feel free to run any compatible appliance. You can get around 100 to 200 watts of power. However, you need to use the right kind of motor.
Basic Procedure for A Moving Bicycle – On the other hand, if you are trying to build a generator on a moving bicycle, you just have to mount the battery holder near the back tire. It will be better if you mount it just above the tire. This way, you will not have to use long connecting wires. You also need to make sure that the wires are tight and don’t get caught up in the tire. The rest of the steps are the same as a stationary bicycle generator.
