Step 2Board to hold timer
This board ('timer board') is going to be tilted perpendicular toward the north star. There is a hole in the center to receive the timer. Underneath this hole is an outlet, stripped of its casing. When the timer is inserted in the outlet, it is held in place nicely.
VERY IMPORTANT: the outlet underneath this board has to be shielded so it is impossible to touch any live parts. After all you will be working with this device in the dark, when dew might be forming!
That is why the power cord should be white, to prevent tripping over it.
This board will be connected to the base board by a hinge. The base board has a strip of aluminum with a slot sticking up. The timer board has a kitchen knob on the side which sticks through the strip. This way the timer board can be set at the proper angle, even when traveling.
To help adjustment I attached an 'angle meter' to the side. I live 52 degrees North, so I have to set it at 38 degrees (90 - 52).
