Self powered bicycle lights systems ( Eco Bike )

thingiverse

From a very young age I have been consumed by a passion for computer science, electronics, and electricity. I create a multitude of projects, but now I want to present this self-powered lighting system for bicycles. There are several accessories included, all designed with one ultimate goal in mind: never having to spend another dime on batteries again. I apologize if my English is not perfect - it's a language that has been stuck in my head for over 14 years since moving from Romania to Spain. This project uses magnetic induction to generate electricity, much like a simple dynamo, but with the added benefit of no friction, making it more reliable than a traditional dynamo. I strive to include recyclable components in everything I create and ensure that all my projects are 100% functional. Here are the print settings: Printer Brand: RepRap Printer: Geetech I3 m201 Rafts: No Supports: Yes Resolution: 0.3 Infill: 30-60 Notes: Attention is required for parts that need support for proper printing. All accessories were printed with an infill between 30% and 60%, depending on their functionality. For example, supports for lights, coils, and magnets require more infill to be tough. I used a printing velocity of 30 (suitable for my printer). How I Designed This The electronic components such as the wire coil, diode, capacitor, and LED lights are sourced from an old TV that was discarded. The LED front lights come from an old ceiling light. A schematic is provided; it's a simple bridge rectifier. The capacitor serves two purposes: filtering current and storing energy to act as a battery. The bridge rectifier converts the alternative current generated by the coil into continuous current used for the LED lights. This system could have various applications, such as charging a mobile phone or action camera. For those who want to recharge their electric bicycle while riding, I can provide schematics for the voltage amplifier/charger upon request. All measurements were taken from my bike (MOMA BIKE), but accessories were designed with more dimensions in mind. If these don't suit your needs, please contact me and I'll create drawings tailored to your specifications. The rear lights box serves two purposes: mounting the rear light and housing a connection box for storage of electronics. One component that may not be easily found at home is neodymium magnets (N52, the most powerful Gauss grade). Don't worry; these are affordable on Aliexpress. I've purchased them before for other projects. LIST OF COMPONENTS: * Neodymium magnets: 24 pieces will cost €8.24 + €2 shipping to Spain. You can use only 16 magnets and save €1, but it's recommended to use 24 for optimal voltage. * Enameled copper wire: I used 0.40 mm wire from an old TV. The formula is simple: the smaller the wire diameter, the longer the coil and more voltage you'll get (my coils produce 12 volts, 6v per coil). * Capacitor: one piece with a rating of 25-50v and 1000uf to 3000uf. More microfarads mean more current storage and more power for charging or lighting. * Diodes: 4 pieces. Any type will do; just respect the schematics (see picture). * Screws: 10 pieces (4x30 mm) and 2 pieces (12mm x 40mm with a 30mm coil axis). * Big LED (6v) bicolor red/blue, 8mmx76mm. Mine is from an old TV, but you can also use 8 normal red LEDs for the second rear light version. * Connections wire: 2.5m piece of typical parallel wire (red and black). The speaker will do the job.
