Close encounters of the garden kind.

It’s that time again to start feeding the hedgehogs ready for their winter sleep, and to put out my IR Raspicam with IR LEDs and passive IR motion detector.

Sadly, no hedgehogs yet.

This is pretty much the same as I used last year with two minor changes:

  • I’m using brighter LEDs in a better range of the IR spectrum (840nm)
  • The LEDs are now only turned on for 10s for each photo – previously they were lit all night.
