Takes (and crops) image from one of the camera feeds in my hometown and makes it available at a stable URL and archives the images for me to maybe make automated timelapse videos later.

Runs in AWS Lambda

Published image at

https://s3.amazonaws.com/files.function61.com/tampere-webcam/hiedanranta/latest.jpg

I show this URL in my constantly-on info display at home.

Why is this open source?

This can't directly benefit anyone, as there are many hardcoded details. But I open sourced this because there might be some details that could help someone:

• Roundshot (the provider that has multiple 360° cameras in my city) URL making
• Image cropping
• S3 bucket access, incl. copying
• Lambda function, hybrid one (can directly run locally but also in Lambda)
• Dead man's switch check-in to an alerting system
  • So that if this stops working, I get an alert

Cropping

Here's how the original image is cropped:
