    Now that Radio Shack is going downhill quick and is no longer selling perfboard,
    does anybody know where I can find a supplier of the plain perfboard?

    Thanks, but neither one has simple (or cheap) perfboard. The only stuff they carry
    is very expensive prototyping board that starts at about $30 and goes upwards.

  5. DigiKey:

    How about items 3405K to 3413K? A 4.5 inch by 6 inch one, catalog
    number 3409K, costs $5.44 apiece and $45.15 for a pack of 10.
    No note of copper pads however.

    How about 438-1022, 4 by 5 inch with pads? $13.78 for one, $12.12 apiece
    for 10.
    438-1040 is a 4.5 by 6.5 inch one costing $21.84 apiece, $19.20 apiece
    for 10.
    Pads are plated-through-hole even.

    However, it appears to be time for me to stock up on what Radio Shack

    Thanks, Don; I didn't see the "pre-punched board" lurking out of the way below the
    nylon spacers and the mounting brackets. That series 7100 also looks interesting
    but both are made of glass epoxy, and I don't know if it can be snapped cleanly
    like good ol' phenolic perfboards. And neither are competitive in price with
    Radio Shack on it's worst day.

    How about $1.20 for a 4.3" x 3.1" piece?

    I googled the following: circuit board perforated
    and found this:

    Scroll about halfway down the list to see the boards they offer (4
    sizes available). It has the individual copper contacts.

    Thanks, Mark. Those are prices I can live with. :)

    Are these guys that high? I used to get these at either RS, or Fry's, or
    Advanced Action Electronics or whatever it was in Santa Ana:

    I've always been partial to the "Pad per hole, with groundplane" style.

    Good Luck!

    When I need a ground plane, I like their single sided copper FR-4
    with 0.035 holes on a 0.1" grid. I lay out the circuit, spot face
    off the copper around the holes that don't need to go to ground, and
    use their T-44 pins to mount components on, on one side, and do the
    wiring on the other side. One handy trick I've found and used for
    years with their T-44 pins and FR-4 board is to put the pin where
    it's supposed to go and then push it into the board with a soldering
    iron. The iron melts the epoxy around the hole, letting the pin
    slide in pretty easily, and then when the heat's removed, the epoxy
    shrinks down and grabs the pin pretty tightly. I've noticed, over
    the last few years, that the board doesn't grab the pins as well as
    it used to, so maybe they've got new punches and they haven't worn
    down to "nominal" yet.

    You're welcome.

    Now I just need to get my brand new SOIC-packaged current source onto
    one of these suckers! The DIP version has been discontinued by the
    manufacturer :-(

    "Everybody has something to hide except for me and my monkey".

    That's all I can offer..;-)

    Actually, it's: "Everybody's got something to hide, except for me
    and my monkey."

    The comma within the quotes might be extraneous and the "except"
    part might be abbreviated to "'cept", but you'd need to do a
    spectral analysis on that part of the white album to find out for
