My take on the Make: birdfeeder webcam.

Step 3 Drill the holes

Drill 1/4" holes to mount the board to a window sill and mount the cam-jar to the board. Drill two holes in the jar lid. One !/4" for the bolt and one 3/4" for the cable. Put the bolt through the board, positioned to the front, and place the lid on to mark the board fot a 3/4" hole. Drill a small hole through the cork about the same diameter as the cable. Make a slit in the cork and slde the cable in place.
