Now I just need a battery powered 40V supply! Brilliant! Let me guess: none of these products are stocked by any of the big distributors, or if they are, they're 500$ each.

Why supply LCDs if you don't supply the backlight controller? The same companies supply touch controllers. Why not a backlight controller? Makes no sense. SBCs aren't designed for "tinkerers". You guys are just making excuses for a situation that's absurd.

Ooooh aren't you a clever boy? Yet still no real products. You spend 300-400$ for a SBC, then what? You get a cheap kludge, or some off- brand mystery part to power it? Clever! Clever! BTW, "battery" doesn't mean "car".

You paid $400 for an SBC and you don't know how to wire a plug? Salesman saw you coming! To be quite honest, your attitude and skills are not suited to this endeavour. I suggest you find an easier hobby or somewhere else to whine. I guess this sort of thing is a product of a consumer generation that just expects to buy ready made solutions, made cheaply in China. It is kinda sad that people don't seem to have any idea about making things any more.
