Make Your Own Tool Roll With Built-in Solar Charging
Tool rolls are a great way to keep all of your tools in order. Darbin Orvar on YouTube made it specifically for storing and charging various electronics.
The tool roll itself is made from waxed canvas and works in much the same way as any other tool roll you would use. From there, the solar panel set connects to the tool coil, so you can charge any electronics you have as long as there is some sunshine. This is a simple yet thoughtful design that can be useful if you are often in the sun while working. Go to YouTube to find everything you need.
