Hi, I am bringing to you an idea that had been done before, but is no longer available. There once was a pre-made PCB design that was made for 2 switches only. This was designed for OSU! I would like to make a new one, but instead use a teensy and red switches, or any other switches. Here is a strawpoll for me to get a general idea of anyone would be interested in me making more than one for myself.
