I've been building Great Ball Contraptions (GBCs) for around five years now and enjoy displaying them at public events. It has been frustrating, therefore, that I have not been able to do that over the last 18 months or so.
It was particularly frustrating because 45678 SPIKE Prime, the new LEGO Education robotics platform, was released last January and I had planned to build and display a number of modules incorporating it during 2020.
Thankfully, public displays have now recommenced in the UK, and I exhibited at three of them during August, which finally gave me a chance to test out my SPIKE-powered modules over a long period of time.
I posted a video of one of them in the Worldwide GBC Facebook group last week which gathered requests for more photos and information, so I thought I'd write about here because it might also be of interest to a wider audience.
