How does the GPs work in a clock?
In my original clock, the microcontroller reads ascii data from the GPS module and decodes the time information from that data. Periodically, the microcontroller’s time is reset according to the GPS information. Here is the problem: it takes time to read the GPS data.
How long does it take to reset a GPS clock?
Periodically, the microcontroller’s time is reset according to the GPS information. Here is the problem: it takes time to read the GPS data. Each NMEA sentence sent from the GPS module at 9600 baud takes about 50-100 milliseconds. Modules vary in terms of which sentences they send.
Why does my clock not work when I turn it on?
Once upon a time most of our clocks were wind-up devices, then we transitioned to electric clocks that plugged into a mains outlet. Nowadays, many clocks are battery powered by a single AA cell. The enemy of all clocks though is dust and grime that can easily seize up the cogs and stop the mechanism from working.
What should I do if my quartz clock won’t work?
Remove any obvious dust or fluff in the movement. If you remove some of the gears, the hands of the clock may fall off, so you may need to remove the clear face plate to replace them. pinterest-pin-it. To get at the mechanism, you need to remove the cover on the compartment that holds the gears and electronics.

Why does my quartz clock keep stopping working?
Sometimes a dry solder joint can prevent the circuit from working or make it stop working intermittently. On some clocks, the circuit board presses against strips of metal that supply power from the battery. These strips are springy and press on tinned pads on the PCB.
Why does the clock on my PCB stop working?
If you have a soldering iron, you can reflow the solder on the joints on the PCB. Sometimes a dry solder joint can prevent the circuit from working or make it stop working intermittently. On some clocks, the circuit board presses against strips of metal that supply power from the battery.
Why is my grandfather clock not working after a move?
When the grandfather clock is not working after a move, there are a few problems to look for that can be easily fixed. 1) Examine the dial on the grandfather clock and check to make sure the hands are not touching or hanging on any parts of the dial or second hand. 2) Check the leveling of the grandfather clock.
