Ian writes – “This is a simple bike light which can be contructed with a minimum of tools. It is bright enough to be useful as a headlight, is fairly robust, and cheap to construct. It’s perfect for commuting and does a surprisingly good job for mountain biking too. The whole thing, including rechargeable batteries, weighs about 200g and will run for over two hours. “ – Link.
