In today's HTL segment we're taking to simple widgets - a novelty keychain and an electronic scales kit - and converting them to run on Lipo cells. The keychain accepts a very wide voltage range and so it doesn't need any regulation, we can just cram a tiny cell with a charger board into it. The scales, however, need a reliable 5v input - so we'll use a powerbank controller to manage a regulated 5v supply and charge in one unit. _ Thanks to music bros down below!
