Sadly and unfortunately, the situation is this. We have to wait. For a year or for anything.
There is a very rare one, who can do and does production for such a rare machine ...
So when somebody does something, an extension or a device or such, we have to sign in immediately, because that is probably a rare situation,
when a private person's life enables him to make those things he likes, and after some weeks or months the luck is turned,
and the person cannot or would not produce those things for a year or two ...
In these situations we can only wait. (Or learn electronics, but it's a hard one.)
