[sdiy] 1-quadrant multiplier with 2164

Because I don't do it to "be in business" -- I do it for "something to do."  I have two or three more module designs just about ready to go into production, and they will be similarly made by hand, one at a time, by me.

And I don't give a single f**k what anybody else thinks about that.  The world has gone stupid, and this is my personal form of protest.

Why don't you get them built by a low volume assembly house and get on with designing more modules ?   Or at least have the PCBs made elsewhere ?
