My wife and I started an online/offline shop last year. When our very first orders came in, it was the best feeling ever! I wanted some kind of celebration device that would turn on and play some celebrating music each time this happened. So I started learning IoT / hardware and build a cool retro-looking police light that I can plug into our WooCommerce/Shopify/Zapier accounts (or really anything else with webhooks). This was such a fun project and people wanted to get some for their own. So I'm working on making it a "real" product. I don't care if it becomes a "success" or not, I'm already so happy to use it for my own and my friends.
