Quickie Projects: Updating a vintage bicycle lamp

Here’s a weekend project that I just wrapped up. Read all about it in the project page

We took a vintage bicycle lamp from the 60’s/70’s (Crown, Made in Japan)

Disassembled it and installed a 3.3V boost converter and a 1W white LED

To make a very bright, but still classy looking light for a classic three-speed bicycle

Lots more pictures and details here…

  1. Vintage? I HAD one of those new. Didn’t seem like that long ago. :)
