Here is a video showing how to take apart a Soundplane and put it back together again. I designed the Soundplane to be easily hackable and repairable; hopefully what you see here gets that across.
If you don’t have a Soundplane but are interested in making a DIY version, this will probably give you some ideas!
Nice one! It certainly stimulated some DIY thought. It looks like the elastic layer has simple air gaps for each junction, which, if that is the case, is quite surprising. More interesting for me, is that it appears to have a PCB for the lower receiver layer, which I'd been thinking of doing anyway.
Thanks for putting that up.
solid elastic works fine too---the gaps are a refinement that reduces the pressure needed to move the surface.
