A lot of us want to build something DIY that can serve us well. And for $95(+switches and keycaps), you can do just that with the Sinc75 kit. The Sinc is a 75% keyboard that is split down the middle, so your wrists can be at a more natural angle. It includes a rotary coder, and also has an option for macro keys and another rotary encoder on the left.
This keyboard is a functional and simple project. You must solder the rotary encoder and the switches, as well as sandwich-style assembly of the top plate, bottom plate, and PCB. The top and bottom plates are separated by M2 standoffs. The PCB does have RGB underglow so you can toggle that on, which will protrude a bit from between the case and plate. The plates are made of FR4 plastic, to help bring the costs down.
Usually DIY projects are fun to make, but not really something you'd want to use on a daily basis. However, that is definitely not true for the Sinc. The fact that it is split tempts me to use this as my main keyboard to help protect my wrists, and the volume knob is a seldom-found feature that is also extremely useful. The 75% layout is also one of my favorites since it is compact but also includes arrow keys.
You can buy it from keeb.io, which is a vendor that specializes in split keyboards. Some of their other popular offerings are the Quefrequency and the Iris. Many keyboards nowadays are variations of the same: a seamless, premium, expensive aluminum design. Seeing a different design that utilizes FR4 plates and a split layout for an affordable price is a welcome change. If you're looking to get into mechanical keyboards or snag yourself an excellent split keyboard, then I would recommend the Sinc.
