Project logs / Re: PIC24 Bedside Table Alarm Clock
[quote author="Markus Gritsch"]Another year, another clock, but for the first time for my alarm clocks [1][2][3] I am not using an MSP430 but a PIC24 instead. Standby current is with 5.5 µA only slightly higher than that of my MSP430 based ones. Time keeping is done using the RTCC pheripheral, which I also used for the first time.
It can be seen in action in this YouTube video:
Friendly green digits :)
And of course it has a LiFePO4 battery on its back, being charged every few years using my new USB charger [4].
A photo transistor is also included to dim the display in the dark. Much nices to the eyes when checking what time it is in the middle of the night.
Here's a picture from the front side:

And here is the wiring on the back side:
I quite like this PhenQ review.

Have fun,
