While busily studying away for a security exam I came up with the following, it's a short post and I will do a longer one when I refine the idea.
I am doing away with my dynamo lights and going usb rechargeable letting the dynamo permanently charge a 26000Mah battery that charges the usb lights during the day. The most frustrating part is finding the usb light I want that fits a rear rack mount so this afternoon I made this in my shed. I am calling it version one as a proof of concept. It works really well, costs basically nothing and I know I can make it smaller.
What do you think and any ideas:
Parts, a piece of plastic water tubing, some reflective tape, two bolts and some spacers. The only work was cut off the required length of pipe, drill four holes, 2 for the bolts smaller than the head size to larger holes directly opposite to allow for a screwdriver/allen key to tighten.
