Well, that’s ALMOST all the top sensors installed: lidar, rotary encoder, light sensor, 2x OLEDs, accel/gyro. Just missing the position sensor for the lens rangefinder cam. Thats a lot of electronics gear in a DIY camera.
I realllllly hope this works. 😄😅

@ChadHillPhotos the range finder isn’t coupled, is it, Chad?
=> More informations about this toot | More toots from Billthoo@mastodon.art
@Billthoo it IS! This camera is bonkers.
There is a position sensor that reads the rangefinder coupling on the lens. All the UP lenses are pre programmed AND there is a calibration process to fine tune it.
Display in the viewfinder shows a traditional (sort of) moving reticule to indicate focus, And shows text of current lidar measurement and current lens focus distance. Also shows light meter info (and a whole menu system) all in the viewfinder!
I’m so impressed by everything on this.

@ChadHillPhotos Oh. My. Goodness!!!

@Billthoo the heads up display also shows a horizon because it has an accel/gyro sensor. 😅
All the data is there so that the overlay mask COULD also move the frame to compensate for parallax depending on focus distance. It doesn’t currently do that, but I’ve talked to the designer about adding it.
After fitting all the components tonight I am feeling super optimistic about being able to complete it. The build instructions are very good and the design is so well thought out.

@ChadHillPhotos wow! I did not expect that!

@Billthoo yeah, i could not resist trying to build this. It’s so much more camera than any of the other cameras I’ve printed.
If you didn’t see where I posted it below, check out the video intro by the designer here: https://www.instagram.com/reel/C63eiv-o6UP/?igsh=MTc2aTZtcGdieGhpYQ==
He also has a bigger version: a coupled rangefinder 4x5 and a better demo of the focusing in the viewfinder: https://www.instagram.com/reel/C4gL02moCqT/?igsh=MWQxbG1qeTJrZ2U2eQ==

@ChadHillPhotos @Billthoo ... A bit late to this. Saw your posts about building a 3D printed camera, but that's astounding!

@Billthoo the viewfinder also overlays masks that combine the lens mounted and the format selected (ie 100mm lens and 6x7, or 50mm lens and 35mm), and the rotary encoder in the film advance knob, combined with you indicating which film mask is o stalled (ie 6x7), allows the rear screen to show you haw far to turn the knob (and when to stop) to get correct spacing.
It’s also got an onboard rechargeable battery powered off usb c.

@ChadHillPhotos Nice!! Looks great too. I wanted to build this.The electronics and programming were/are too much for my skills. The building part is really fun though. I made a Brancopan a few years ago, and more recently a Nanopano. Fascinating to see them finally work. Looking forward to some images when it's finished!

@selyfriday I have built a pretty good number of electronics projects and am reasonably handy with a soldering iron and I was pretty intimidated by the guide. Not everything was clear until I started actually assembling it.
But the guide is actually quite good.
Now that I have all the components and can see how they go together it is not NEARLY as difficult as I imagined and the total amount of soldering is low.
Most components just drop into well designed mounts and get daisy chained. 😅

@selyfriday I had to get a few extra daughter boards printed because the minimum was 5, so if you wanted to try it I can send you one! I’ll also post photos of the completed electronics when they are done. 😄

@ChadHillPhotos Thank you but I had another look at the assembly/board/wiring.... and I think I have too many other projects need doing before this. I'm afraid it'll sit around not getting completed. But thanks for the offer.
=> More informations about this toot | More toots from selyfriday@mastodon.art
@selyfriday no problem!

@ChadHillPhotos looking at that circuit board you posted a picture of, it looks like it’s all through-the-hole discrete components, no surface mount. True?
=> More informations about this toot | More toots from thereisnocat@toot.cafe
@thereisnocat yeah, it’s mostly designed to use the adafruit “stemma” connectors to chain the components together and then the board is all headers connecting things or a couple of these jst-xh plugs mounted in the through holes. No surface mounted components. There is a little cable fabrication to be done, but I’m using pre-crimped ends and just splicing them together.
I’m happy to send you a daughter board. 😅

@ChadHillPhotos Thanks. I would appreciate that.
=> More informations about this toot | More toots from thereisnocat@toot.cafe
@thereisnocat no problem. Dm your address and I’ll pop one in the mail.
I’d never ordered custom pcbs before, from a provided design file, but it was surprisingly easy (and also not expensive).
=> More informations about this toot | More toots from ChadHillPhotos@mastodon.art
@selyfriday Also, I expected to run into issues loading the firmware to the board, but it compiled and installed very smoothly.
I am so close to being able to finish it, but I have to wait for the position sensor for the lens which is in-transit from China!

@ChadHillPhotos Okay, now I’m going to have to dig into this further. That’s absolutely wild. I had the github tab open in Safari on my phone, but hadn’t looked at it yet.
