Fellow Shadow Watchers,
Why not have an electro-mechanical 'sun tracker'
on the roof with an electro-mechanical 'repeater' in the room which could
be placed on a wall for easy reading. This could take the shape of a
'hour hand' on a 'dial' with a 1:24 gearing to drive a concentric hand to
show minutes. A simple ambient sunshine detector would switch off the
tracker when the sun was obscured with a warning light on the dial to
indicate this. When the sun re-appearerd the tracker could then switch
to 'search' mode to relocate it thus avoiding frantic spuirious
indications below.
Digital clocks are cheaper of course but making it work would be a lot of
fun ;-)
