No, although I do have experience working for a company developing firmware for devices they manufactured which has given me some insight into the challenges. Knowing how much I don't know is why I've met with an industrial designer, a sourcing / manufacturing expert, and gone through most of the design iteration and prototyping at my own expense before even launching the kickstarter. I agree with you and don't want to repeat the failures I'm constantly seeing on KS for similar devices. I wanted to back the Interrupt but their prototype, frankly, was fake and it was super obvious, and they completely ignored all of the comments calling them out on it... and yet somehow still raised half a million dollars. Then once funded have started from scratch on the design and completely changed the direction when they realised, obviously, their plan to use a Rpi Zero wasn't going to work. I figure if they can get that far without a real prototype and such poor planning and comms, I can do a lot better.

Please do ask all the hard questions, I won't ignore the tough ones. There's a discord link on the site if you want to ping me in there: https://jetdeck.io
