So I am to the point where I need to solder the LED displays to the board that actually fits in Junior's head. I did a much smaller test, but then couldn't leave it alone. So, I taught Junior to sing some Beastie Boys. I think it will be much more impressive when he is assembled and I add the emotional responses. https://youtu.be/OUb9kyYhtOM
Junior singing
Hi Kyle
I recognize that voice :) Sound like a well known scientist. And a ( to ) small speaker box too..
Good work.
