Sadly my lens has not perfect back focus, since I‘m using a system camera there is nothing I can change about that. The effect is a little bit compensated with using BlurXTerminator.

The image is cropped a quite a bit, the aspect ratio is still 4:3 however.

No just the phone while walking around the setup at different distances

Austria :)

Thank you for your work.

As far as I understand it one of the big advantages is that every viewer simultaneously provides its download data for others to stream (peering). With this approach server capacity can be reduced but I wonder how well this works (If I even understood it correctly).

With this system could it be possible to host videos on an own server without having to pay huge sever costs?

Also what is a nice website to search through all videos, similar to the front page of YouTube?

Ha thanks!

Nice!!

Thank you!

Thank you for your nice comment!

The stripes are called walking noise/ pattern and often show up when not using a tracking mount and not using dithering.

Because not every pixel of your camera captures signal exactly equally bright you‘ll see this difference along the movement of the sky as it gets accumulated with every subframe. The only way to get rid of it is to vary the pixels for each part of the image after each exposure. This can be done by moving the camera slightly after each shot. This process is called dithering.

With good calibration frames the pattern can by minimized very slightly. Other than that the only real option for processing I can think of is to hide the pattern by not stretching the dark ares too much.

Other than that great image!

Ich gehöre seit heute auch dazu. War ein langer Kampf, letztendlich hat alleinig die Gesetzesänderung zur Durchsetzung geführt.

I didn’t check but would guess right about one hour. Plus ~30min registration. Normally I just start the process and leave my laptop and come back later, so I don’t know for sure.

Absolutely stunning image! Thanks for sharing

Also we were quite surprised how bright the nebula is. We didn’t thought to get that much signal with 15min exposure time. Even more so as our camera is not infrared modified.

Interesting, how much power does the laser have to need to be able to burn the paint?

Haha, the board won‘t win any prices for sure. But for a first try I‘m still very happy.

I used this code as the base and changed it slightly so the pump has a safety time out and can be controlled via PWM.

In newer projects I use code from Espressif however because it works with Matter and Threads.

Yes exactly. It checks the weather forecast however so it doesn’t water when it‘s raining. This way I don’t have to refill the canister too often. A better way would be to attach moisture sensors to the plants, but I don’t like having to change batteries constantly. This is a very simple solution but it works for me.

I just printed the design on a glossy paper and used an iron to transfer the toner from the paper onto the pcb (last image). The toner protects the underlying copper in the etching process, so only the free copper gets etched away. I used Na2S2O8 for etching.
