I hate to be nitpicky but it annoyed me that you kept saying you were increasing the “power”, you’re not increasing the power with that gearset, you’re increasing the torque.

I watched the video again and from what he says it sounds like If there’s no keyboard plugged in when the device boots the HDMI port is disabled, but the device still boots and you should have access through the serial terminal or ssh ( Once you’ve setup a password of course ). Although for anyone who was thinking of taping one of these to the back of a TV and trying to use it as a media center, that would be very annoying.

No public wish lists :(
