PIC24 bedside table alarm clock
https://www.electronics-lab.com/pic24-bedside-table-alarm-clock/
Markus Gritsch posted pictures and code of his PIC24 bedside table alarm clock: Another year, another clock, but for the first time for my alarm clocks. 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 […]
LiFePO4 charger
https://www.electronics-lab.com/lifepo4-charger/
Markus Gritsch shared his LiFePO4 charger project in the forum: Since I really like using LiFePO4 AA and AAA batteries in some of my projects, I finally gave in and built a dedicated charger for them. Previously I used a lab power supply to mimic the constant current/constant voltage charging curve, which worked also fine. […]
