- I have a working prototype on breadboard which is tested

- the PCB is designed and will be produced within the next days

- the missing parts will be ordered when the PCB arrives

UPDATE:

Here's a picture of the prototype on stripboard. I looks ugly, but it works! The only problem is the USB port. With soldering only the 4 pins it's not solid enough so you HAVE to drill the two holes for the port holder.
