Minecraft – How to activate a piston only for a few seconds when the the daylight sensor activates

Horizontal to horizontal (north to east, etc)
Use the same design, but put a redstone torch under the "hotspot" where the blocks will be pushed towards.

Horizontal to downward
Note that the input can be received from either opposing side (and you can move either the "red power line" or the "white receiver line" if you want to two "inputs" to come at 90 degree angles instead)

Horizontal to upward
Same as the above design, the input can be received from either opposing side (and you can move either the "red power line" or the "receiver line" (the one with the repeater) if you want to two "inputs" to come at 90 degree angles instead).

• The piston is a sticky piston.
• The repeater has to be set to 2 ticks.
• The glass block is required (but can be replaced by any transparent or non-solid, pushable block)
• The half-slabs are required (but can be of any material, or glowstone can be used instead)
