I've always loved flashlights. Yes FLASHLIGHTS with an A!!! Anyway, apparently not many people share my rather niche interest.

So I ask you, fellow Lemmites, what are your hobbies and weird obsessions that you can ramble on about for hours?

Please feel free to ramble on about your passions here. Maybe you'll find some likeminded individuals!

  • Laser holography and optics. After I took an photonics course I became obsessed. I am attempting to build a laser holography setup to capture "true" 3D reflections on a piece of film. Even getting cheap diode lasers to lase coherently at high currents is a challenge. It's a black hole for money so I need to limit myself but it is just so fucking interesting.
  • Cameras. I am not a good photographer but I love cameras. I can ramble on and on about every single function detail and the history too. I even built a scientific camera for my job from scratch. And beyond that I even started getting into the math behind distortion correction, stereo, panorama etc.
  • 3D printing is a major rabbit hole. Especially if you've built your own printer.
