This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers.
Post your project, your progress from last week, and what you hope to accomplish this week.
If you want to be pinged with a reminder asking about your project, let me know, and I'll harass you each week until you cancel the service

Kinda. I've done a proof of concept that was just a rangefinder using a monochrome SPI oled and some plastic lenses and a different time-of-flight chip, and that did have longer range than this layout will (although you start running into eye safety issues trying to exceed 50m). This one's more intent to be closer-range (the spec sheet says four meters and that's being generous), but gives a reasonable depth map across a wide field of view. Assuming I can get the data off the chip anywhere near the right speeds, the next step's going to be trying to get this into a wiregrid map overlaid on the user's field of view.
If that works with a low enough latency that it doesn't cause an Exorcist revival, mid-term goal is to try to use that map to project virtual desktops or graphics to solid objects, first from a fixed viewer position and then as the user moves.
Most of the current implementations for that sorta stuff depend on fidicuaries like AprilTags (or QR codes) and thus visual-light cameras that have a wide variety of privacy concerns, or solely handle angular heading. I don't think all of what I want to try will work -- these glasses near-universally give up on pinning virtual items in absolute position to the user for reasons, as anyone that's tried to integrate IMU data into position will tell you -- but there's a bunch of things you can do if you're willing to give up the general case and might work.
Cool -- I've got an older gen TOF plus a little oled unit and an old (broken) rangefinder box from a press camera (all sitting in a plastic baggie) that I've been meaning to frankenstein together into a focus assist hybrid display for large-format cameras. Time is short, but I'll get round to it.
Curious how it looks for accuracy once you dig in -- probably less important in your application, but I need <5cm on the near end; much less demanding as distances get larger tho.
