With all due respect to those of you who like dynamo lights, there are plenty of threads in the archives about this light vs that light, dynamo vs battery. I respectfully request that anyone interested in those subjects feel free to search the archives, resurrect old threads or start new ones.

This thread is about home built light systems. It's not a debate about what is best. In my case, it is not even about what is most practical. It is about having some fun and creating lighting systems that you can't buy, mostly using parts you can replace easily and inexpensively.
