In this video I show how I modded my LiPo charger to send me emails when my batteries are charged (or anytime its alarm sounds) using a cheap Raspberry Pi Zero.

It’s easier than ever to make nearly anything “smart” and are there are probably countless uses for a device like this, perhaps especially for the hearing impaired.
I was inspired to build the ‘MintyMailer’ when I moved my charging station to the garage and wanted some kind of notification when it completed a cycle. That got me thinking ‘Internet of Things’ (aka IoT) and wondering what would be the simplest and cheapest way to get an email when the charger’s buzzer went off.
An in-depth look at the build including links to parts, sourcecode, safety concerns and getting started with the Raspberry Pi are available on my CradyLab™ website:
I hope this inspires others to build something similar. If you do, please share a link to your project because I’d really like to see it.

*** About LiPo Safety ***
If handled improperly or if they are damaged in some way LiPo batteries can be a fire hazard. This is especially true during a charge/discharge cycle and as such batteries should never be left unattended while connected to a charger. My personal charging station is located on a steel rack away from combustibles and a smart smoke alarm [that is audible throughout the house] is positioned overhead and a fire extinguisher is nearby. As a final precaution my batteries are always stored and charged in ammo boxes or fireproof bags designed specifically for LiPo batteries.
