ive already have in the past when i got 50 boards made up and produced a DIY kit

the problem is, any howto is specific to the the circuit or board you're using. if you dont know how to interpret a circuit schematic and lay it out onto some kind of prototyping board to make your circuit, then you need to buy a board from someone who's already done that
its not cost effective to get a single pcb produced if someone gave u the design for it (eg if u were able to use the design i made there) as it would cost more than buying a premade one would.
calum has a construction guide for his consult interface also (bit more bulkier than my one was, but a slightly better circuit design) - in the forum contributors section. theres a good chance someone may have some empty boards left from a previous pcb production batch run they did
