Touch is the most encouraging sense.

The blue mould gave me tangible proof that this idea was worth pursuing. There was an abundance of layout options and customisation that was possible just by pulling apart the pieces and rearranging. I just needed to think about how they would connect and then source a PCB. The scary part.

I decided to edit the blue mould to make room for a prototype PCB and/or handwired test as well as adding magnet holes so the parts would align themselves. This was quite simple to change and I had new 3d printed parts in a week or so. You can see in the images I left a 2mm wall around the edge, and left the plate to be around 2mm as well. This made room underneath for a proto PCB as well as including 5mm neodymium magnets to the connecting edges. 1 kit includes 12 magnets. This made evetrything fit together and feel really nice. This led to the video you see below and the Reddit post that followed.

After creating this and getting the feedback that I did, I was able to really understand what was needed from this project. People commented on what connectors would be good, what options they’d like, if wireless was an option (still!) and I set out to create a PCB. The dreaded bit. Course I had no clue, and I asked around. The first name I was given to help me was Yiancar, a local electronics guy from the UK. We talked at length about the problems and issues with connectability, and at first, we figure out a double loop system that created a complete circuit, but we quickly realised this wasn’t feasible, and we set on figuring out (with the help of post-it notes and many messages) how else to create this system. Yiancar was awesome at helping me visualise how this system may work and the issues we may face.

This is pretty impressive. Looking forward to seeing the PCB implementation! Great work!
