    OK, it's 03:30 in the morning, I'm on vacation, and I get out of bed to clean up my bench...... man, something is wrong with me.

    Thinking about a few projects on the bench.......

    Anyway, as I'm cleaning here (and listening to soldersmoke) I came across a project I'd like to use in some of my QRP rigs - a Hendricks keyer. Neat little board, built and ready to go.

    However, the thing is so tiny, no holes and such for standoffs.

    Any good ideas on how to mount it clean in a case/project?

    My bench is a mess, but I try to make my projects look clean as I do a bunch of buildathons throughout the year and many people see some of the projects before they build one (don't wanna scare them off with some ugly construction now..... ).

    Come to think of it, even ugly construction has a beauty all it's own....

    Anyway, thanx in advance for any tips,

    Hot glue gun?

    If it is small but going to be mounted in an enclosure along with other boards you may could make a few stiff wire standoff's soldered to the board ground. I have done a few that way.

    Don't be so afraid of making a commitment.
    1-hour epoxy.

    You're right.... something is wrong with you! Go back to bed! :D

    That makes it difficult to reuse a project later. There are horizontally slotted nylon standoffs that will slip on the board edge withour drilling holes. Otherwise, you can usually use nylon (think insulated!) screws and nuts to mount the board by it's edge.

    Some people (including some manufacturers) use foam tape (such as for mounting pictures or posters) although that may deteriorate over time.

    Is this the kit you have?


    I have mounted little boards like this by cleaning the ground plane circuit board, then mounting it vertically and soldering it directly to another circuit board, or a solderable metal cover or shield.

    Simply scratch clean below the word "mute" and "paddle" and solder tin these spots. Place it perpendicular to a metal or open circuit board area, then tack solder the spots. Repeat the process on the opposite side of the board. You now have several "solder bridges" holding the small board in place.

    Double-sticky tape

    Look for the double-sided sticky tape with the foam core . . .

    I've used it for years mounting Com-Spec CTCSS boards in radios.

    Looks to me like this was designed to be panel mounted, by the 3.5mm jack.

    If you use enough 1-hour epoxy to completely cover the item, you'll forget it's there after a while, and you won't have to worry about how to reuse it later.
