I'm a grad student in mechanical engineering at University of Washington. I build cameras.
A twin-lens-reflex camera for use with FP100C/FP3000B instant film. I Kickstarted this one.
A 3D-printed superwide camera using a Mamiya-Sekor 50mm f/6.3 lens. Looks and feels glorious, but there are some light leak issues I haven't sorted out quite yet.
A 3D-printed box camera that's completely open source. Nothing gutted from existing cameras, parts easily purchased from Anchor Optics, McMaster.
The first light meter I made, using a TSL2561 and a laser-cut acrylic enclosure, and an OLED display. Works pretty well.
A neat little light meter I made for my meterless film cameras. Uses the TSL2591 I2C light-to-frequency converter, and has a huge dynamic range (0.01 ~ 120000lx). Still need to make a cute little enclosure for it!
