ULiTv:Yeah, it's very rugged but the main problem is that it emits a lot of heat. The 7815 ic regulator needs a standard heatsink |

Nice one, I done see person wey actual go school today. |

Very nice. But most phones rely on smps and buck converters (power banks) for charging phones these days. This may not be safe for high end phones. If you keep doing your research I believe you will be able to improve on this. Well done. |

I don't think there is anything extraordinary here. This is a simple bridge rectifier and linear regulator, probably 7805. Most chargers use smps (dc- high frequency ac- dc) the regulation is done with the aid of feedback loop |

ULiTv: You omitted something very important. How much did it cost you to build? |
Re: A Nairalander Built A Mobile Phone Charger (photos) by Nobody: 10:36pm On Mar 16, 2022 |
ULiTv: Well done bro. You can improve gradually to systems like automatic light switches with PIR sensors, remote start/stop switches for generators, automatic outdoor lightings etc. Then you can commercialise your brand to your neighbourhood and beyond. |

Stamagba: If my knowledge of physic is correct, the load will draw as much current as it needs, assuming it's a purely resistive load, depending on the rating. The issue there is that the 7805 ic can only handle, I believe 1.5 amps |

irukandji89: Bro smps design hard oh. I have bee trying to design a sepic converter. I just downloaded power supply cookbook and many other books, recently I've decided to leave that and focus on embedded systems design with pic microcontrollers using CCS c compiler. My only problem now is time. I do three jobs 1 Like |

This is too elementary, I hope you are just a secondary school student and not an elect/elect graduate. |

The op did not build anything. We assemble this stuff for school back then.just get the schematic diagram nd put the components the way you see it. Shikina |

[quote author=ULiTv post=111082718]Components used for this project includes . 1) 240v (9-0-9) transformer 2) 4 Diodes (no unit) 3) 1k/25v capacitor 4) 7805 transistor (regulator) 5) 0.1/25v capacitor 6) light emitting diodes (led) 7) USB port a connection board . I first of all connected my four diodes in series, then my 1k/25v capacitor followed by transistor, 0.1/25v capacitor, light emitting diodes, USB port then my 240v transformer on the connection board, I read it with my meter and it gave me exactly 5v. You can watch the video below please I want to learn more from you. |
