This solar fridge is a simple and quick diy project. The reason I decided to build it was because the fridge in your house takes up a ton of energy. This fridge is so cheap and reliable that it can be used in 3rd world countries. It takes about 15 to 30 minutes to complete and it only cost around $15 dollars.
Here is what you need
1 large clay flower pot
1 small clay flower pot
sand (I used about 1/4 of a bag)
towel
water
clay or plumbers putty (only needed if there is a whole in the bottom of the pot)
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.
