Hydra protection

My Hydra just arrived a few hours ago.
I would like to thank Andre LeMothe as the text is excellent and exactly the introduction to video and gaming that I was hoping for.· It is very difficult to find this kind of introduction, overview and retrospect in the computer world.

Anyway, as with all my printed circuit boards, there is some concern about protecting from shorts and static.
I personally am quite happy and comfortible with hot glue.· In fact, I buy green hot glue locally for my projects.

So in order to prevent future disasters while enjoying the Hydra, I have 'hot glued' the back side for insulation.· As you can see, I do this with other boards too.· For rework, a utility knife can easily cut out what you need to remove.· Soldering seems not to be interferred with.

So... let the games begin.

    Cbmeeks,
    I suppose for some this is sacrilege [noparse][[/noparse]it is a beautiful board], but the hot glue will remove easily and clean up with mineral spirits.
    If you work like me, you try to start out neat, but there is always clutter creeping onto the work bench that
    can short the backplane.

    In the past two years I've taken a couple of such hits.

    In short, I really plan to use this a lot [noparse][[/noparse]share with friends and kids] and with all the cables it is going to be dragged into obstacles - some conductive.

    Kramer,
    Why are you teasing us with that picture of the bottom of your board? We want to see the top side!

    Kramer,

    Since there are mounting holes, why not just mount an Acrylic or Plexiglas backing to the board? ...I know, I know there's something irresistible about fluorescent green.

    It may seem silly, but it is quite hard for me to get a piece of plexiglas locally. Language barrier and shops want to do production runs, not one off parts. And, obviously the hot glue is quite inexpensive. I could use a blank piece of printed circuit board. Or I could look for a plastic chassis box, but enclosure leads to other challenges.

    Can you find conformal coating? I am not sure if there is another technical name for it. We spary our production PCB boards with it to protect them from corrosion and the shorts that you are talking off.

    Yes indeed, conformal coating is used by the military in both sides of PCBs to protect against humidity,contaminants and scratches.

    It (conformal coating) can also help dampen vibrations. We used on circuit boards used on leveling systems used on various types of semi-trailers that were mobile facilities.

    We used it for protection from the elements, the vibration dampening was an unexpected side effect!

    Foam card and some double sided tape works well too.

    As does a square of car floor mat or some or the non-slip sheet made by Duck.

    The problem with conformal coating is it's difficult to remove. You can use a soldering iron to burn thru most conformal coatings - but it's not the method I would use for more than a handful of connections.

    How about latex? It peels off pretty easily, don't know how it would react with the board though.

    An easier thing to do is this, get a piece of black construction paper, lay the hydra on it, cut out hte hydra square, punch 4 holes into it, put the constructin paper under it, there you go. But, there are 3/4" standoffs, so I never have trouble with shorts, even on the carpet. But, the construction paper method looks nice, is easily removable, and of course doens't ghettofy the board [noparse]:)[/noparse]

    Call the ghost busters. Slimer just attacked Kramer's Hydra. :P
