I am interested in all of the above! I've bought 2 mechanical keyboards now, but am now looking at split ergonomic keyboards w/ thumb clusters, and the price ranges on those are higher than what I'm willing to just shell out for a keyboard I'm not certain is perfect for me. I found a thriving DIY sort of community that designs their own or finds an open-source project that matches their hand size well, and then they buy/order most necessary parts, but then many 3d print the case (and sometimes even the keycaps), and most kits require soldering, which I've never done.
Someone here pointed me towards the MK Tech Center with
mechanicalkeyboards.com in Chandler, which I didn't know existed, so I'll likely be heading down there to get the keyboard questions answered. Still, if I end up deciding to DIY and solder... I think I'll stop by sometime during public hours to figure that out! It seems there are classes for some maker skills, and I would be interested in one of those for soldering small electronic parts.
