When you have built a nice circuit, the bigst problem is how to create an “UI” for it that everyone can use – I can still recall my Micro Power Converter – it was 2.5cm^2 big, but no one could use it but me; and even I needed a control voltmeter and a screw driver.
Jakob Selbing ripped apart an old Nokia cellphone and found out that the PCB works well as an input/output terminal – enjoy!
