I have finished building the pcb. It surprisingly pretty easy apart from a few problems. Firstlt ive never soldered before and had to learn as i go. Secondly i soldered the rotary encoder bent but it works. Thirdly i burnt the plastic switches trying to solder the upside down seed pins. And lastly my cad model was wrong and the pcb doesnt sit flush with the lid so i had to imprvise and keep the lid at an angle. Currently im working on the firmware
