Hydraulic steampunk clock movement

[DickB]

I've had the idea for this clock for quite some time, but only recently got to working on it. A small 12v pump continuously circulates water to the siphon. The up-and-down movement of the float drives a ratchet wheel, which in turn drives the gear set. The pump's speed will be regulated by a microcontroller to set the siphon cycle at exactly once per minute, so that the ratchet wheel will drive a minute hand directly. Right now it's running open loop at about a 40 second cycle. The gears in turn drive the hour hand. The gears are temporary, from another project, just to prove the concept. Likewise the lever and pawls are temporary. These components, along with a face and hands, will be designed in a steampunk fashion.
