Convert Analog Alarm Clock

The old alarm clock is alive for 6 hours and then, it needs to be wound up. The "tic-tac" noise avoid the usage in the bed room, but the design is really nice. Let's make a new alarm clock that requires a battery (for 1 year duration) and makes no noise.

• Old alarm clock (max 10 Euros)
• Dremel rotating tool
• Pliers
• Screwdrivers
• Hammer
• Strong glue, normal glue
• Cutter blade
• Modern clock mechanism
• 1 screw

Make a good place on your table to list all required tools, and start to disassemble the clock. Start to remove everything on the back.

Continue to disassemble the content of the clock, removing the cogwheels. Keep them in a plastic bag, someone can use it (you can sell or reuse it).

Now, take the Dremel rotating tool to separate the frame (grey metal / golden metal). Just remove the part of metal on the rivet, and use a pliers to detach it. Keep with you only :

• All external parts (back, frame, glass, screws, etc.)
• All hands of the clock (4 in this case)
• The white clock face, with numbers

Check that the new mechanism can find a place in the grey metal frame, and nothing else have to be cut. It's important to keep a maximum of rigidity on the frame.

The new mechanism should be centered with the clock face hole.

Check that the new mechanism works well with its hands of the clock.

As you see, the new hands are not great. So, I had to cut the new and old hands to create a new one.

The pictures shows how to build a new one, with a strong glue.

Let's do the same job for all hands, and put all together in the new mechanism.

In my case, the new mechanism have to be moved back, because the glass pressed it.

Finally, glue small hands (under the hour 12 and above the hour 6).

All right, everything should be fitted when all parts are reassembled. Hands should be moving softly.

For keys on the back, use glue to fix it definitively.

I've added a piece of wood to fit the back frame at the right position.

Finally, add a crew to fix the back frame.
