Whoooop whooop @Frank_fjs that sounds mega awesome!!!1111einselfDesign is finalised, I'm placing a PCB order this week as I want to test it before going public.
I'm really looking forward to this. I'm just a bit worried that I can solder it my self. I never soldered SMD parts and I have no idea where to buy them Anyway I'll find it out and I'll give it a try. You grow with the challenges says a german saying.
I just donated some money for the new prototype. Btw I have no idea how much one AUD is worth it and what you can buy with it. So I hope it helps
