Ever since watching LOST, I’ve always been interested in owning my own flip clock, like the one in the Swan Station. Split flap displays have been around since the 1960’s and are still used in many train stations to display the train schedule.
I think these displays look really cool, and it’s always interesting watching the displays change, as they can’t just change every word at the same time, it has to go letter by letter until the correct letter shows up.
In this Instructable, I’ll be taking an old split flap alarm clock and turning into a cool piece of mechanical art. You can buy very similar clocks online anywhere from $40 to $100, but I’ll show you how I made mine for just 2 bucks. I think this could make a great gift!
Step 1: The Find
The hardest part of this Instructable might just be finding the right clock for the right price. You can buy a retro flip clock on eBay for under $30, but if you look in Goodwill and other thrift stores, you might be able to find one for a great price. The one I’m using cost me $2 at my local Goodwill.
If your clock looks anything like this, you will probably be able to follow right along. This is the second clock I’ve modded like this, and even though they were different companies, the insides were basically identical. Just make sure it actually has a split flap display. Also, check online to see if it’s actually worth more than you paid. For example, the alarm clock that wakes Marty McFly in Back to the Future is actually worth a decent amount money.
Step 2: Open it Up
Opening these clocks is pretty simple. You just need to remove the screws on the bottom and pull off any knobs on the sides or top. The knobs might need a little force to come off, but they should come off without damaging anything.
There should be about four screws under the clock’s display. Leave those in for now-- They hold the display mechanism in place.
