If it has ever crossed your mind to wonder why I haven’t been posting lately, the image above is your answer. You’re looking at the BC419143B, a microprocessor designed to output Bluetooth. In theory I will be building a chording keyboard that uses this device, but before that I had to design a circutboard for that purpose. You have no idea how long I have spent on this 1×3 inches – I do not want to think about it much myself.
Look at a slightly more complete version of the board here. And expect more information, including some details about the firmware and case, in the coming days.
