My god this guy needs a non-technical cofounder.

He has one: https://www.crowdsupply.com/people/alexsoto

Wenting's YouTube channel is all technical demos of display hacking, and this is the only where he's selling what he worked on.

Neither of them are using YouTube to advertise.

Oh cool!

I didn't mean the YT wasn't good content. The video fascinated me, and I watched the whole thing.

I meant he is a brilliant engineer doing what brilliant engineers do. He improves things.

I get that the hardware development lifecycle differs from the SDLC. I am out of my depth. But it seems he needs his business partner to say, "Good enough. Ship. Test product market fit. Iterate."
