Ema Stack stackable gadgets system

thingiverse

I had a vision to create a modular system of gadgets that could be used frequently. The idea revolves around having a battery pack with built-in USB charging capabilities and contact points on top for powering other devices, which are secured using magnets. Each additional device has contacts and magnets at the top for seamless connectivity. Devices like lanterns/lamps, Bluetooth speakers, clocks/barometers/thermometers can be connected, and electronics will be based on widely available and affordable boards. As the set evolves, I'm planning to integrate a battery pack with built-in solar charging, gesture controls for lights, Wi-Fi/screens to display information from the internet, motion sensors, etc. The list of features is endless. Currently, I have finished two versions of the battery packs: one holds six 18650 batteries and another with six 18350 batteries. Additionally, I designed chargers with one or two USB ports, and a tiny lantern add-on. I use these battery packs daily for about two months now, and they make for an impressive collection sitting on my desktop, although they can be bulky to carry around. Soon, I will publish the list of materials/components used and DesignSpark Mechanical source files. At this point, I'm seeking your feedback - does it make sense to continue developing this concept? Would it be useful? Do you have any suggestions for improvement? Thanks!
