I am using a Raspberry Pi Pico to provider a pacemaker signal to a broken flip clock that needs to trigger a change every 12 hours.
As a proof of concept this works and does what it's designed to do. However the current 500mAh battery only lasts a single day. Please note the LCD LED is disabled during stand running, not on as shown in this image.
How can I lower the power consumption to increase the run time?
My current thoughts are:
- Remove/disable LEDs (Small indicator LEDs on some of the components used)
- Underclock the Pi (Touched on here https://www.raspberrypi.org/forums/viewtopic.php?f=145&t=304309&p=1821617#p1821617, but the example links to create a new Pico image don't work)
- Use RTC to enter low power mode (However no MicroPython examples are available, so I'm unable to try this)
