I designed a pocket music instrument. I partnered with a company in China called Seeedstudio, they do the manufacturing, shipping, customer handling, etc. and I receive royalties on each sale. I varies from month to month, but above the 500$/month on 2025 :)

I love to be able to focus on the design and not the practicalities of selling a hardware product!
