Using Dead Batteries to Test for Dead Batteries -- Episode 571

Dead battery? That's a matter of perspective! Instead of recycling coin cell batteries when their time is due, I will put them to good use and show you a secret feature of a Raspberry Pi Pico - and what sets it apart from other microcontrollers. Let's use the dead batteries to check for dead batteries, so I never have to doubt the battery again! I'll end up with a nifty box to keep my batteries organised, tested, and ready to use!

Perhaps you could use Karen's 'juicer' to extend the life of those dead batteries even further?

How did I miss the battery juicer when it came out? That's cool.

I love when this happens. You think there is nothing new, and you have to wait for a new release and then boom, you find 2-3 videos you haven't seen before and you know your evening is sorted :D
