    I'm looking at either finding or making some small PC boards. They need to
    be about a 1/2 inch square. I'm wanting to mount an LED on each board but
    I'll need to connect 4 LED boards in series but each board will be connected
    to the next with insulated wires. I could either have a board with 4 holes
    right down the middle but then I would have a long length of wire for the
    negative side of the source. I was thinking of having a board with four hole
    on the upper half and two on the bottom half. The bottom two holes would
    just be a place for the negative wire coming in and one going out to the
    next board. The two center holes on the top half would be for the LED wires
    and the outer holes on either side would be for the positive coming in and
    one going out to the next board.
    So would it be easier to make a board as such or find something to work? I'm
    new at this so I'm looking for help and direction. The only thing is that
    the side the LED is mounted on to remain smooth so that means all the wires
    and LED legs to be soldered on the back side.
    Thanks for your comments and help.
  2. Radio Shack sells small pieces of (paper impregnated with phenolic)
    prototype board with holes on a tenth inch grid, and a pad around each
    hole (single sided, not plated through). These are easy to score with
    a file and break into small rectangular pieces along lines of holes.
    You will have to use fine wire to connect pads together, if you need
    this. They also have several versions with rows of holes connected
    together. You can use an Exacto knife or moto-tool burr to cut breaks
    in the lines.

    For circuits this small and simple, John's suggestion
    is probably the way to go. But if you want to make real
    etched circuits for this, I have detailed instructions and
    tips for how to do it using a Sharpie marker, a Dremel
    tool, and ferric chloride etchant. See:

    Hope this helps!
