In part two of this blog series, I introduced my idea of using paint rollers as the mechanism for allowing easy rotation of the foam massage rollers that trigger keyboard switches connected to the Xbox Adaptive Controller. If that perfectly logical sentence isnt crystal clear to you, you may want to start from the beginning before reading further. As things worked out, I didnt have near the free time over the last weekend that Id hoped for, and I only made a fraction of the progress Id intended. However, a couple helpful suggestions from the comments on last weeks post lead to the acquisition of some new hardware thats worth talking about, lets start there.TR gerbil llisandro read my mind and suggested Kailh Speed switches as an option for a switch that would actuate with a very small amount of travel. Thats something Ive discovered is especially important for the method by which theyll be triggered in my project. I ordered Bronze and Copper switches from Novel Keys , and they arrived in just two days.
