Daniel O'Connor@lcamtuf That is very cool, also holy shit is that a lot of switch
Dan Connolly@lcamtuf "I started with rigorous budgeting: I figured out what would be a reasonable amount to spend on the project and then multiplied that by 10."

@lcamtuf also, I think you could get a much cheaper (but almost certainly not as reliable or nice feeling) switch from someone like LCSC, eg https://www.lcsc.com/product-detail/C693824.html
Szymon Bęczkowski@lcamtuf Great work. The next step is to make it tiling with magnetic edge connectors so you can extend the board to any size.
