Lego GBC Observer 👁 Week 08, 2020

Apologies for the late post, but here we go.  The GBC Observer for week 8 of 2020.

First up a utility item that every GBC builder will need at some point, ramps.  Nonsense Wars talks us through his thought process when designing ramps for use in his GBC layouts and testing.

Next up, this interesting module uses a chain drive to lift up small levers in sequence that propel the ball forward.  On the way back down the chain resets the levers.  Now I don't think this would meet the spec for one ball per second, but if you had 2 or 3 of these going at the same it might be possible.

And here is Huw's take on a ball sorter using the newer Lego Education Spike Prime kit.  It's using one motor to drive the wheel, and then a colour sensor and motor to sort the balls into the correct output area.  Very simple, elegant, and expensive thanks to the pricey Spike Prime components.

Have a great (short) week everyone!
