bjornhallberg, this is an excellent project. I’ve noticed that you ordered your components from AliExpress instead of mouse, farnell or digikey. I mostly order my components from farnell or digikey since mouse is a bit expensive. AliExpress is cheaper than all of these by a mile and I have been thinking of ordering from their stores but I can’t risk placing an order and not having my components delivered or not having the components that I ordered delivered. Please let me know how you found their service. Congratulations on a successful project by the way.
