RPi Target Livecam
A Raspberry Pi with a Camera Module pointed at an air-pistol target board, streaming the live feed to a web app any device on the same network can open, and saving a frame whenever you shoot a good series.
My father-in-law had an air-pistol range, but standing 10 metres away it was very hard to tell where you had hit the target. I set out to solve that real-life problem by building a live-streaming camera that hosts its own web page, so the target can be viewed from anywhere in the house by anyone interested.
Live video stream
Pi Camera feed captured with picamera2 and streamed with low enough latency to follow shots as they land.
Web app
A Django site hosted on the Raspberry Pi to watch the feed from any device on the same network, no app install.
Save your series
Capture and store a still of the target on demand, so good groups don't vanish.
