Making it is no problem. Cheapest way is on VeroBoard, though NOT very professional, it will probably work.Doing a PCB, for me, is no problem. The cost of a board might be.... I just had 4 made for my new project from the USA on a 1 day delivery for 160$ US all in.
I'm happy to do the design work for nowt, if needed, but stumping up the cost of boards will have to be someone elses problem to sort out. I can also sort out all the components, where to buy them and building instructions.......
As a guide on the PCB, up to 9 square inches, 10 off costs 180$ all in , so $18 each.20 off $288.
I don't have time to do research on this, but I do have time to copy things...Hope that helps.
