This is a knex blinds opener, powered by the red battery pack motor. It is activated by tunring the motor on in one direction to close it, and another direction to open it.

It has a rubberband wrapped around the wheel which gives it the friction to grip onto the blinds cord. WIthout it the wheel spins but the the cord doesnt move.

Tell me what you think, and please rate too. Also, if you think i should post, tell me in a comment.

Thanks, hiyadudez.
