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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
