On the subject of the captcha system, how would a blind person join this forum?
I've spoken to blind musicians before, and I'm aware that blind people use the internet with screen reader software. How would they solve a visual puzzle, like that one?
I agree that the power cable is far too short. I've extended mine using a guitar pedal daisy chain lead, for now, with short pieces of silicone tubing pushed onto the unused power jacks.
Why not use a USB socket for power instead of the 2.1mm jack socket? Those are typically used for 9V or 12V DC, and even 9V centre negative, for guitar pedals. Would the Anyma Phi survive someone plugging in one of those, by mistake?
If it had a USB socket instead, it would be less of a problem because we almost all have a variety of USB leads, of different lengths.
