Hey, if it helps, We had a need for a consumer-focused product based on the ESP32 that I work with every day, and can vouch for DeepSeaDev. Were able to do the work and provide the IP.
Great suggestion, MIT also has a deep-dive into Additive Manufacturing, which are all different miniature factories. https://learn-xpro.mit.edu/additive-manufacturing. 3D printing really helped me make the leap from virtual --> physical products.
Small company - but we've have been building tools for Guitarists, centered around our LED display system. https://www.fretzealot.com
Personally in charge of hardware, firmware, and too many of the things behind the scenes. About to crowdfund our V2 with hugely improved hardware and LEDs.
Covid was fun with MCU shortages and years lead time, so now that we've survived that things are looking brighter.
Some people like it just for the light shows, but we get lots of great feedback across the board.
Been rewarding to build a tool that I actually get to use and benefit from on more-or-less a daily basis.
