I have over 35 years experience as an electronic design and PCB engineer, please see my profile for more details
I believe I could help with the PCB design and manufacture but not the case or the software. I have recently designed several Blue tooth products using Nordic and TI devices NRF 8001, NR51822, NRF52832, CC2541, CC2564 and the Laird BL600 and MDBT40 hybrids. The devices contain a mixture of Flash, orientation / motion device, RTC, LED's and buzzers.
I have contacts in China so could help with the mass production of this product.
The current price and timescales are only place holders to allow me to communicate with you
If you use inductive charging then it will make the unit much bigger as the antenna takes up a lot of room.
If you think I could help then please come back to me
Best Regards
Dave Lelievre
