Modding A Casio W800-H With A Countdown Timer

(*3*)

Inventory, the Casio W800-H wristwatch ships with twin time modes, more than one alarms, and a stopwatch – helpful options for some. Alternatively, extra is conceivable when you simply know the place to appear. (*2*)[Ian] made up our minds to dive below the hood and allow a countdown timer function hidden from the manufacturing unit.(*13*)

The Mod comes to popping open the case of the watch and exposing the again of the principle PCB. There, a chain of jumpers keep an eye on more than a few options. [Ian]’s principle is that this permits Casio to save lots of on production prices through sharing one elementary PCB between plenty of watches and enabling options by way of the jumper variety. With a bit solder wick, a jumper pad may also be disconnected, enabling the hidden countdown function. Different options, such because the more than one alarms, may also be disabled in the similar manner with different jumpers, suggesting lower-feature fashions use this identical board too.(*13*)

It’s an invaluable trick that suggests [Ian] now all the time has a countdown timer on his wrist when he wishes it. Excuses for over-boiling the eggs will now be a lot tougher to come back through, however we’re certain he can deal. In fact, watch hacks don’t should be digital – as this practice clear case for an Apple Watch demonstrates. Video after the ruin.(*13*)
