I have been quite busy with all manner of things in the past few months, but this project has had some love. (Unlike just about every other project I had in my queue...) I am currently working on a build using pogo-pin-style connectors and magnets to hold the blocks together - TBH I'm not sure it is going to work, but I am discovering some other potential options if these connectors are not quite right. I am trying to mock up some case designs to fully test the new connectors and hope to have a proper update for this project in a few days.
Wish me luck! 8^)
