What if we made a camera that sees in reverse?

If you’re interested in messing around with data from the camera I’ll be posting some of the raw data for these pictures on my Patreon: patreon.com/stuffmadehere. Also, THANK YOU to all the patrons who support these projects!

When you made the real life Orthographic Photo I was so happy for you. That's a huge deal.
Awesome video!

I wonder if your camera could be used to simulate what animals with different shaped irises would see such as horses, goats or cats, or octopuses.

if anyone else was curious, the transimpedance amplifier he talks about at 10:25 is listed at $537.91. I can see why he wanted to build his own

I know it takes a REALLY long time to create your projects and edit them. But I'm going to need you to take stimulants, stay up 72 hours per day and pump out one of these every 3 or 4 days

"There are a finite number of issues, and then eventually it works." Having a rough time with an engineering project right now and that was really good to hear. It's been true many times before, and it'll be true this time. Awesome work.

All you need to see around walls is a dense enough object to perform gravitational lensing. Can your CNC work on singularities?

[stickfiftyfive]

Woow. That was all amazing.
1. The device itself.
2. The genius in your idea of making it in the first place, and then actually doing it.
3. The patience of a non-mortal in error handling and problem solving to achieve said end.
4. The pictures themselves.
5. Your *amazing* talent at concise but brief explanations of the basic concepts you're working in here.

Bravo good sir.. blown away 💥

It's so funny that the answer to "How can you see around walls?" is essentially "put the camera on a stick so that it peeks around the sides of the wall." lol

Fun fact: all of these wacky lenses simulated in this video actually exist, and are widely used in manufacturing and inspection! Telecentric(no perspective) lenses are most common and very popular in metrology, but pericentric(seeing more than one side of the object), hypercentric(seeing behind and/or underneath the object), and even wacky combinations with mirrors. This allows you, as a common example, to inspect the cap on a plastic bottle from all sides, at the same time, using the same camera. Above, around the corners, from the side, AND from below!

1 minute in. Your description of how a camera works. 10/10. Never thought of it like that and proof of the concept of "if you can't explain something complex to a child you don't understand it well enough yourself"

You think u studied engineering and did photography for half a dozen year, u know a lil something about optics. And then this guy comes around and proves you wrong. Honestly amazing work, I look forward to each and every video of you. Thank you for making engineering and mint so interesting.

I have a PhD in mechanical engineering and watching your channel really itches every scratch that made me go for engineering in the first place. One of the last remaining channels where I watch every second of every new upload without a second of distraction. Absolutely impressive every time. You say "the unsatisfying answer is a lot of math an science". I must say, just thinking about the whole code that takes the voltage readings and then transforms it into a pixel image using the kinematics of your motion gives me butterflies. I will never forget when I visited a Computer Vision lecture and the Prof. one day showed us the inversion of the Radon transform that created the foundation for CT scanners. He also had this gift to make every lecture like a tense thriller, but this one really left me so speechless, I it took me 10min to find my jaw on the floor again... Till this day it makes me happy just thinking about it sometimes. Math as a tool for engineering can be DEEPLY satisfying. :))

You got your mythological creatures mixed up. You were thinking of a hydra ;)

[TheSlicingSword]

the way you can describe everything in such an understandable way with simple drawings is amazing. ur drawings (and/or whatever software ur using) is so satisfying

[jakobfink]

There’s absolutely no other YouTube channel that I look forward to as much as this one! The content here is simply outstanding, the quality is unmatched, and the way complex topics are presented in such an engaging and fascinating way is truly remarkable. Every new video feels like a gift, and I can’t wait for the next one to drop. This channel isn’t just entertaining; it’s a genuine contribution to society. Incredible work, keep it up!

[sebastiansteffen]

This project can not stop with this video. Dont start a next one yet, instead have some fun with the camera and do a second vid. The picture turn out too nice to put it aside now

[GrzecznyPan]

With every vid I do admire your bravery on putting your great talent and knowledge to YouTube instead of some dull, well-paid engineer position in a big corporation. Respect, congratulations and thank you.

Him dropping a video is almost like Christmas. It immediately makes my day at least a bit better
