Toys are great, this is my newest one:
It's a DIY build, and I fortunately found Mechboards in the UK selling kits. And, err, don't mind the chaos on the Pro Micros, I was sent the wrong acrylic cases which I only noticed after I had soldered the four hidden switches + the Pros. Couldn't find a tin sucker :/ All that's left is to find the motivation to put Alt Gr somewhere, and to decide whether I should make my own homing marks (because I had to shift around the rows and the stock ones would end up on the wrong row) or buy a fresh set of DSA keycaps.
Going to Russia again on Sunday, hopefully this time to run the actual SRC experiment. Or rather, a new technique/setup in a suite of SRC experiments.
And that's it, have fun.
