I stumbled across geekhack while researching why my keyboard has a limitation as to how many keys could be pressed.
This community is super cool, has crazy depth of knowledge, and real passion for crafting. Respect.
I finally found out about rollover and then got sucked into a rabbit hole of other information, from switches to key caps to reversed-spacebar thumb flicking. You guys are awesome, I'm glad to be here and look forward to losing all of my money doing some tinkering alongside you folks.
