The keyboard is an open source one called the hillside [1]. It has a niche little thing called a puck on the bottom of it that allows standard 1/4” thread mounting to many tripods/camera accessories [2]. The clamp is off of Amazon and has rubber so that it won’t damage a computer, it is very strong and not easy to alter. [3]
