The PCBs are pretty easy to assemble, all thru hole parts and nothing too small. Basic soldering is about all you need to know. The TIU tester has it's own thread we should probably move over to. Here's a link to the other thread where GRJ developed the PCBs and files for getting the PCBs made. The link goes to a picture of the one GRJ built and there is another picture of one that JohnF built on the last page of the thread. Stan also posted some info on how to calibrate the tester when finished. I have not gotten that far on mine, still working on it. The boards I have are exactly like the one's in GRJ's post that I linked above, got them from the same place and all the parts are from Digikey.
