Essential Gbc - Red Stripe Grey Stripe, By Pinno Deal Alert: 45% Off [LV2D4nQk]

Red Stripe Grey Stripe is an astounding Great Ball Contraption from Pinno. 

This GBC module is featuring a very clever mechanism with ten receptacles mounted onto a circular link tread chain.
The gearing system of this marble run machine contains a mechanical stop and start mechanism influencing the rotation from the link tread chain.

Thanks to a stepper, GBC balls are loaded into the receptacles located underneath the chain.
At the end of the chain, balls are dropped into a take-off ramp.
Once the next receptacle is reaching the end of the chain, it is kicking the ball waiting in the take-off ramp: it is catapulted alongside the exit ramp.

You can now reproduce this brilliant mechanism thanks to easy-to-build kit available on BuildaMOC
