Adapt a clock today! Cheap trackers boost solar panel and solar cooker performance.

Step 2Fitting a "gearwheel" to the clock.

Fitting a \"gearwheel\" to the clock.
Here is the central post of the hour hand. I will fit the piece of plastic tube to it and use the peice of tiewire to join them together really strongly! Then I slipped an old medicine contianer lid over it, screwed it to the plastic and put on the top pice of the medicine container. This now was the timing device for the new tracker!
As the clock turned, the twine slowly unrapped from the lid. The lid was almost exactly 2 inches wide. This means it releases (2 pi r) 6.28 inches of string in 12 hours.
My tracker has a float in water which has 8 inches of travel before it hits the bottom. This means I can track the sun for 15 hours with this clock!
clocks are weak but the weak tick, tick, tick movement is slowed and strengthened by 60 times to move the minute hand and slowed and strengthened another 60 times to move the hour hand. 3600 times the strength should be able to move what I want!
