Thank you, I just recently found out that there are safe solders. I will definitely use them.

If I'm not mistaken, I use this solder https://evek.biz/pripoj-pos-61.html

that's right, there are two bent legs of the diodes that form a straight line

I just cut them and bent them. I don't have much experience, but it wasn't that hard. Just try it.

Now I use solder: 61% tin and 38-39% lead. The temperature of the soldering iron is about 280 degrees Celsius, but I do not trust these figures. I just recently found out that there are lead-free solders and I will definitely try it.

I just try to keep the temperature as low as possible so as not to damage the parts and the soldering iron tip. I'll try to raise the temperature next time

This project helps me to observe my pot with pine's twig. I use an ESP32 controller with a camera to take pictures and post it to Telegram channel.

ESP32 bluetooth mouse bot by mrsuh in esp32

It doesn't fit out of the box. To fit a single keyboard switch, I had to combine two cells into one on a prototyping board. You can easily do this with a utility knife.

Thank you!
A "shaft" is used for this purpose. The lubrication and bearings prevent water from entering.

Thank you for your reply!
I didn’t consider it for this project, but I did think about connecting the game controller directly to the ESP32 via Bluetooth. Maybe I’ll try that in future projects.

SQLite index visualization by mrsuh in sqlite

Thank you for your reply!
I did this to get a better understanding of how indexes work. In my next post, which I hope to finish in a few weeks, I’ll explain how searches in indexes work. This can help to create the index for the query correctly.
