I produce these Kokonauts http://instagram.com/kokonautinc http://instagram.com/kokonautinc Started using development boards and designed the pcb around it with the sensor and sold as a mvp. Then later the entire board and now iterating on that. Use CAD to design the board such as KiCad, Diptrace and then get the board produced at jlcpcb or oshpark. You can assemble the pcb with the components at Pcbway, Seeedstudio, Aisler, etc. Started manually flashing the firmware and every step was done by hand. The firmware flashing and testing is now automated. Continuing working on further automation. The board house also offers to do this but it's done by hand and I thought it would be fun to work on automation plus it saves a few dollars on each board. The software follows the usual software development lifecycle. The enclosure initially used 3dprintuk (jlcpcb also offers 3dprinted enclosures too) to produce. Now use a Prusa Mk3s+. FDM 3d printers are getting really good so not sure when to get injection mold. Quality of injection molded part is still the best. You can get a resin 3dprint (jlcpcb offers that) then vacuum cast for a few hundred for a few pieces before injection mold.
