This evening while straightening up the basement I decided to play around with combining parts from two previous projects (a commuter light picked up at the MMBA Expo and the Bicycle Video Recorder) and it seems to work. I’m able to use the rather large LiPo battery and voltage regulator to get the requisite 6V, and it seems to power the light nicely.
The light should be mountable on the crown of the Mukluk, so maybe I’ll put this to work as a low-mount night riding light for winter use. I’ll just have to sort out the battery mount, but that shouldn’t be a big deal. Yay, another project!
