Dropping some images and videos of the build progress here for now, will fill in more details about these steps later. A key development this weekend was that I was able to salvage parts (velostat and thin foam) from a DDR controller I found in the ITP junk shelf (what are the odds!) to build my new tiles. I have built four sturdy tiles and will continue to add more as time allows. They are fairly modular, but each tile needs empirical calibration to find the right pressure-to-resistance ratio .
