The shock wave of the Tonga eruption in the Carpathian Basin
So let’s visualize the shock wave as it traverses the Carpathian Basin changing the atmospheric pressure. Videos and interactive map below, and what my arduino recorded through its BMP180 senzor, more about it in the videos.
My OBS keyboard – source code
So the whole thing is made in Arduino, one Attiny85 board acting as a USB client, a HID keyboard, and another board, a Nano (ATMega 328P) on the lookout for button presses. The two communicate via serial.
And the source code is published on github here (the USB-handling attiny85) and here (and the buttons-handling nano).
Below is the very first, unoptimized implementation, barely fitting onto the flash.

On Creating a Lunar Mosaic
2014-10-20, Moon-mozaic, showing the assembly process with the overlaps
One of the, we can perhaps call it this way, standard challenges any amateur astronomer faces is photographing a lunar mosaic. In other words: taking a sequence of large resolution images of different areas of the Moon, to assemble it later, and thus gain a large landscape but with the added extra resolution. Pretty straight forward. And everybody who’s ever attempted such an endeavor is familiar with stuff going south, picture below. (tovább…)

Venus, first light 2021-12-23
At 13:43 local time, I had the first light with the new ASI 485 MC camera. Although the new driver made it visible in sharpcap 3, it only worked correctly in sharpcap 4.
