My name is Walid F, and I’m a rising junior at Smoky Hill high school. I am intrigued with solar power and love to build my own creations. Since I come from a very sunny place in Africa, I came to learn, and expand my creations to solar  back home. My starter project is the minty boost phone charger, and my main project is a solar powered phone charger. My dream is to one day become a successful entrepreneur!

Final Project Video

My BlueStamp project is a solar charger, which I converted into a solar charging stand. It was a very rewarding project. I hooked up a 6W solar panel to a battery, a charger, and a boost to my phone. I learned a lot throughout this project, one of the most important things was that solar power is VERY unreliable. I spent many days testing until I got the correct voltage and efficiency I wanted. Essentially the project has a solar panel connected to a Li/Ion, charging the battery. And from the same Li/Ion the battery then charges the phone. Although I am done I plan to keep on modifying my project for more everyday use, and use more solar power for some speakers, making a more efficient solar power machine.

My main project schematic

Calculations:

I1: 960mA     I2: 960mA      I3: 770mA      I4: 660mA

V1: 4.26V      V2: 4.23V         V3: 4.93V

P.Solar: 4.26V * 960mA = 4.0896W   P.Batt.in: 4.23V * 960mA = 4.0608W

P.Batt.Out: 4.23V * 770mA = 3.2571W  P.Phone: 4.93V * 660mA = 3.2538W

V= Voltage   I= Current    W= Power(Watts)     V= I*R   V*I=W

Here is my bill of materials:

6W solar panel

USB LiIon/LiPoly charger

Minty Boost

Lithium battery

Micro USB

Starter Project

For my BlueStamp starter project I made a MintyBoost by adafruit. It’s a backup power source made of two AA batteries that allows any device that charges through USB. It is a device where using resistors I got an exact voltage of 5V, the standard voltage for my apple products. I learned a lot about the flow of electricity (electrons) through the wires. I also learned a lot about resistors and toning down for a precise level of voltage. I struggled with soldering the first resistors flatly on the PCB board, but then got the hang of it, and now apply all that I learned into other projects.

    I’ve been inspired to make great things because of you. You are the sole reason why I started coding and inventing. My mix tape ( link below) was made to honor your dedication and commitment to the Blue Stamp program and will serve as a reminder to you that have created a path that many will/are follow/ing.
