G'day, ...
I am a Australia Electronics Engineer and Altium PCB designer professional, with 25 years experience in Manufacturing. I specilaise in taking ideas into mass production.
I have built quite a few projects with similiar components of late ( and fitted them all into a smartwatch!)... Your project is quite in depth, and not for the faint hearted, or newbie hobbyist maker! I would welcome discussing it further with you. With my experiance, and the fact that I also I also work with SolidWorks for full 3D modeling of the projects you can rest assured of knowing what I design can be manufactured cost effeciently. If and when required, I also work along side some specialist Industrial Designers and Software Engineers to deliver the complete design.
...and of course my bid is just a placeholder so we can chat about your project and to see if I am a good fit for your needs. :)
I look froward to chatting more...
Cheers,
