LED Cycle Lamp
High-tech on the trail
Although a true homebrew design this lamp has a truly professional feel to it. The aluminium body is designed to be watertight and requires some machining. The design uses four Li-Ion cells connected in parallel, each with a capacity of 2.2 Ah. A microcontroller takes care of battery management allowing the lamp to be charged at 5 V from either a mains adapter or car adapter.
