This is as a replacement for "DIY Webcam particle detector" physicsopenlab.org. Here atomic theory is weak about alpha ray, the first in the picture:
Materials:
- rpi 3+ running bookworm;
- raspicam without lens;
- smoke sensor, exposed americium: alpha ray source;
- case enclosure from a torch reflector -> from the little hole the raspicam CMOS look inside the case towards the alpha ray source[/img]
Running in term:
- libcamera-hello -t 0 (running infinite loop video)
- libcamera-vid -t $duration -o video.h264 (record video)
- # Convert h264 to mp4
- ffmpeg -i video.h264 -c copy video.mp4
A little screenshot of one vidHoping I'm doing well!!!
It's so hard to write here!! Nore charge vids!
