    Electro-Pnuematic Grip

    After seeing The-Electriction's and Trains are Bad's projects, I am very intrested in building one on my own...however, I would never even consider buying a board like a morlock and spending hours programming it, I would rather buy a Basic Stamp from Parralex(sp) and program it myself. It's not like I have no experiance here. I have built two other similar boards, one as a replacment for an electro spyder, and another to replace the one in the cheap dragunfire LED that I use as a backup, to give it full auto capabilities and an LCD. The way I always built it was this, written so you don't need a knowledge of PBasic to read it:

    At rest
    When the trigger is closed, give power to the transistor that activates the solenoid
    Wait Dwell time
    Turn off transistor, closing soleniod
    Wait Drop time
    Go back to "at rest"

    This is, of course, highly simplified from the actual code, which if I can find, I will post. However, I want to clarify how the automag works. In a mech automag, when you pull the trigger, it releases the sear, which allows the bold to move foward, cutting off airflow. To do this electronicly, one uses a solenoid supplied by a LPR, which when activated allows air to flood into a ram, and when de-activated, allows air to flow out of the ram, aided by the fact that most clippard rams (SM-6, or the one I'm considering) have a spring return. So the code would look like:

    At rest
    When trigger activated, power a transistor (I don't like putting lots of current through my board) which opens the solenoid to allow air from the LPR into the ram
    Wait Dwell time
    Close first transistor and open second, allowing air to flow out of the ram freely
    Wait the drop time
    Goto "at rest"

    Once again, obviously VERY simplified

    Can anyone comment on this and give me some suggestionas or pointers? I would esspeccially like to hear from THe electrician or Trains are bad

    Thanks,
