Last year, some friends and I visited Mechanicon, the largest keyboard convention in Europe. Here, enthusiasts can present their creations and vendors can offer their items, with a prize raffle concluding the event. Sadly (or perhaps luckily, given that I didn’t need something) I didn’t win anything, however I did manage to pick up some low-profile switches from the trade corner. Once I had some switches in hand, I knew what I wanted to do: create my own PCB and keyboard. A numpad, to be precise. Since I have time to design my PCB and learn new things, how hard could it be?
