So you know when you have an idea kicking round in your head but there are a few problems to solve before you can make it. Well I wanted to make a wearable but was struggling with a way to do the strap, I was browsing aliexpress and came across a watch strap called the “nato”. This strap would let you thread it through a PCB and insulate it from your wrist.”
