EDIT 2023-07-03:

I fixed wrong description of initial clock of MCU (thanks [mention:c20f43d074634ad58fe82a5d320c7fbe:e9ed411860ed4f2ba0265705b8793d05] for pointing this mistake). Following sentence

.... At first powerup of MCU it starts with default 16MHz clock and is quite a power hungry before I reconfigure clock to some slower and let MCU sleep. ....

was replaced by:

.... At first powerup of MCU, it starts with default clock (MSI prescaled to 2.097 MHz) which is faster than clock later used by my firmware (MSI prescaled to 0.524 MHz). Before clock reconfiguration, MCU consume more energy than later in execution time after reconfiguration. ....

I fixed missing manufacturer in the BOM table of first solar pannel entry. Manufacturer of solar panel which I use (AM-1417CA) is Panasonic.

Your project is well done.

Just a remark regarding the MCU restart clock (STM32L053) which is not the HSI source, but actually the MSI in with default range 2.097MHz.
This is stated in RM0367 section 7.2.3 MSI clock.

Nice post.

You have a good starting point to collect data and see how the circuit works over time.

You will have to do a heat transfer measurement on the Butt Paste as opposed to standard lithium grease.

Do you also cook with the ointment ?

Good to know the delta T is there but absolute temperature isn’t fixed. I have s Peltier cooler in a drawer here but haven’t powered it up. (My plan was/is to generate volts in the winter. Peltier, Seebeck, tomayto, tomahto)

Interesting project, but I hope you realize that with the poor efficiency of solar cells, you could get a much better mug heater if you just used a lens to concentrate the sunlight directly.

Duuude - you probably needed a sip of the tropical beverage in that mug to record better readings
