Give your smartphone solar assist with this modification from instructables
Phones tend to be out of battery right when you need them most. With this project, you can extend your phone’s battery life just enough to make those emergency calls! You just have to set your phone out in the sun for a while, and you’ll have just enough power to send a text or make a short call.
To modify your phone, you’ll need the following:
An approx. 2″x2″ solar panel I got mine out of a broken electronics kit
A dremel w/ cutting disc I got mine at Harbor Freight Tools
A Smartphone The project can also be done with a typical phone.
Electrical tape In my case, all I had was bright red, shiny tape. This made for an interesting project.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
