As a full fledged geek I have full fledged geek dreams. Itís not unheard of me for me to remember dreams about school clocks once or twice a month. Iíve fixed clocks for my hometown schools in the past and once in a while Iíll dream about being back in the school and getting the old clocks running again. These dreams are obviously prevalent because of my keen interest in all things connected, including these early and mid 20th century clock systems.
The Historical Society in my hometown set up residence in one of the school buildings closed in the early 1970s. A former classmate has led the effort in restoring the building to its former glory, and the cafe-gyma-auditorium is now a popular spot for banquets, wedding receptions, and other community events. The building has clocks from other schools in the district, including the last wooden cases clock left intact from my elementary school. Iím hoping to get their clock system working again the next time we go back East.
The clock pictured above is a gift from another clock system enthusiast in Central Ohio. Beautifully restored, I am planning on installing it in my office here at home. Iím debating whether to cut a hole in the wall to mount it properly or ask Chris and Mike to build a frame for it. Either way I hope to have it up soon. Itís a touch of class my office needs.
The clock canít really keep time, it advances once a minute by a 24VDC impulse from a master clock originally located in the principalís office or something. Originally pendulum based clocks, motorized clocks replaced the function in the mid 20th century and then electronic clocks took over the duty in the late 1980s. My clocks run off a Raspberry Pi switching a simple relay to replicate the impulses needed to keep the clocks on time. Surprisingly, this clocks is not particularly loud.
I look forward to getting this on the wall. Iíll probably dream about these clocks in the next couple of days.
Such a happy geek.
