/diy/ - Do It Yourself

I suppose it works like this
while depressing the key the switches are closed in order, from furthest one to closest.
measuring latency between signals from these switches allows to calculate exact parameters of keystroke.
simple, easy to repair design but I'm thinking if there could be a better way to do it with magnets suspended under the keys and then analyzing induction in coil underneath the key while avoiding induction from other key or eliminating it in calculations somewhat
