Solar garden lights…. How on earth do they manage to sell something with a solar panel, rechargeable battery, step-up converter, LED and the plastic and metal casing for a dollar/pound. You can’t even buy the bare components for anywhere near that, in fact the solar panel alone would probably cost you five times the cost of the whole light!
This project is about hacking your solar lights to make them different colors and potentially increasing the battery life too.
Solar lights are great to hack. They’re cheap enough not to worry if you mess up, and very gratifying because they are effectively free to run due to being powered by sunlight.
