Bike lights are expensive. Mine advertised itself as waterproof to 50 meters (for deep sea biking?) and used a magnetic power switch to keep itself hermetically sealed. This promptly broke and rather that shell out another $20 for a new one I decided to bolt on a push button switch I had. I also have the habit of leaving the light on and draining the battery so I decided to use the opportunity to upgrade my bike to solar power.
I’ll admit it is a bit of overkill since the only power needs were my front and rear lights. With all this effort I decided to add on a USB port to charge my phone since I use google maps a lot during longer rides.
Make your projects to go green this summer with our specialized USB/Solar Lithium Ion Polymer Battery charger! This charger is a very unique design, perfect for outdoor projects, or DIY iPod chargers. We’ve spent over a year testing and tinkering with this charger to come up with a plug and play solution to charging batteries with the sun and we’re really pleased with what we ended up with.
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.
