Haha, the board won‘t win any prices for sure. But for a first try I‘m still very happy.
Sure thing :)
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.
Yes UV is so much nicer, I also use this method now when I‘m not ordering online.

As I don‘t have a water outlet on my balcony I use a water tank and a pump for watering my strawberries. I developed a controller for the pump which runs natively on Apple Homekit but I‘d like to change it to Matter and Threads in the future.

This was my first try developing my own pcb with the toner transfer method. I did this project many years back but it works perfectly to this day.
It filters an audio signal and drives led strips so they pulsate to the beat of a song.

I use uYou plus. It has to be installed via Altstore (which means you have to resign it once a week with a computer needed in the same network).
But it has the best features:
Dank dem Gesetz haben wir nun endlich auch ein BKW. Unsere Hausverwaltung hat in der Eigentümerversammlung angekündigt, dass ein Ablehnen in Zukunft nicht mehr möglich sein wird, und so konnten alle Parteien überzeugt werden. War trotzdem ein langer Kampf, und ohne diesem Gesetz unmöglich.
Ich hoffe das wird vielen anderen genauso helfen.
Tl;DR The EU makes sure that third party developers gain access to connectivity features to develop devices like smartwatches, headphones or VR headsets that have a deep integration to the OS.
It is crucial that the request process is transparent, timely, and fair so that all developers have an effective and predictable path to interoperability and are enabled to innovate.

Also this is what our setup looks like to shoot such an image:
We shoot this image over two nights to reveal the faint structures of the veil nebula complex.
Shot with a 135mm lens and a Fuji X-T5.
I can recommend this online telescope simulator where you can simulate the field of view with your equipment. Your 300mm lens should be absolutely perfect
I found this design and it fitted my need perfectly. It is a mount for a very popular camera lens used in astrophotography. It not only functions as a weight relief for the camera but also allows to rotate the field of view. Moreover it is possible to focus the lens with the installation of a stepper motor, which will be the next step.
The single parts are screwed together with the help of threaded heat inserts. Just to make sure they are also glued together with epoxy, as the mount really needs to hold up. The screws are locked with Loctite.

As we didn’t find any shelf of our liking we tried to create it ourself. It worked out better than expected, however it obviously isn’t perfect. But as completely laymans we are happy nonetheless.
One cool feature is that through all pieces goes one straight hole, this allows putting lamps on the shelf without seeing any cables.
Interesting, how much power does the laser have to need to be able to burn the paint?
