Hi all,
I'm probably your least favorite type of person to drop in around here. Super new to ee, no engineering background whatsoever, has silly idea!
Been thinking about an ornamental timepiece for a while, and figured I would always design it mechanically like your regular automatic watch (using a mainspring). However, the longevity and no/low maintenance advantages of using a battery are now apparent, although I'm certainly more nostalgic for a nice winder.
The idea is to send a brief .5 second electromagnetic pulse from one side of the clock to the other, once every 24 hours. Essentially it's a mantle clock that has digits 1-30 around the clock face in lieu of 1-12 (Yes, I realize not all months have 30 days). The quick pulse pushes a small magnet about 5-6 inches away, which gears the clock's single hand 1/30th of a revolution, which obviously needs to occur only once every 24 hours (preferably like clockwork!).
I'm hoping to use a 3 or 6v lithium button battery. Not knowing much about electrical engineering, It feels like this shouldn't be too hard? I think i have a basic schematic that is maybe close, it goes like this: battery to something like a 555 to an rc oscillator to a capacitor (or two?) to the very small electromagnet (2lb force). Can't help but feel there's some redundancy here though. I like the electromagnetic route because of no actuating parts connected to the battery.
As you know, I'm a bit out of my depth. Any light that could be shed with regards to any of this would be greatly appreciated! Thanks in advance.
