A proper good-bye to Little Backup Box

Little Backup Box has been by far my most successful and popular project. But about two years ago, I chose to transfer it to a new maintainer, effectively abandoning the project. The other day, it occurred to me that I had never said a proper good-bye to my project. So here it goes.

As it often happens, I started working on the project to solve a problem I had: I didn't want to schlep around a laptop when traveling, but I wanted to have a backup solution to keep my photos safe. As Raspberry Pi had been making waves as a versatile platform for all kinds of projects, I thought I'd try to build a Raspberry Pi-based backup appliance that would replace a proper laptop. And over the years, various Raspberry Pi models running Little Backup Box served me well during my travels.

Powering Raspberry Pi Zero with a 3.7V lithium-polymer battery

While you can power a Raspberry Pi through the dedicated USB port, it's not always practical. In certain situations, drawing power from a small and thin lithium-polymer (LiPo) battery makes better sense. This is especially true for projects based on Raspberry Pi Zero, because of the board's modest power requirements. The good news is that powering the Raspberry Pi Zero using a regular 3.7V LiPo battery is cheap and relatively straightforward (some soldering is required, though).

Incorrect wiring or wrong output voltage can damage the Raspberry Pi or the battery. Working with LiPo batteries can be dangerous. MAKE SURE YOU KNOW WHAT YOU'RE DOING, AND PROCEED AT YOUR OWN RISK!
