Does anyone know if it is possible to repair the Parallax 7.5 V Wall Wart Power Supply? I pulled mine out of my power strips only to see that one of the Power connectors was left in the power strip. I have pulled it out but am wondering if it is worth the time to pull it apart and try to repair it.

    Hie thee down to RadioShack, and obtainest a new one. Thou dost not need the headache of breaking one of these apart to fix it.

    Hearken to this: PhiPi's "thou dost" and "obtaineth" references steereth me back to my favorite SciFi novel, "A Canticle for Liebowitz". Ignorant but well-meaning Catholic monks in the desert, preserving crumbling paper documents centuries after the "Atomic Flame Deluge"...

    I may just have to dig that book out again...

    Excerpts from http://www.apocalypsebooks.com/canticle-leibowitz

    Bantam - 9th Printing - Feb 1982
    "It was said that God, in order to test mankind which had become swelled with pride as in the time of Noah, had commanded the wise men of that age, among them the Blessed Leibowitz, to devise great engines of war such as had never before been upon the Earth, weapons of such might that they contained the very fires of Hell, and that God had suffered these Magi to place the weapons in the hands of princes, and to say to each prince: 'Only because thine enemies have such a thing have we devised this for thee, in order that they may know that thou hast it also, and fear to strike.'

    "But the princes, putting the words of their wise men to naught, thought each to himself: 'If I but strike quickly enough, and in secret, I shall destroy those others in their sleep, and there shall be none to fight back; the earth shall be mine."

    "Such was the folly of princes, and there followed the Flame Deluge..."

    Bantam - 5th Printing - May 1978
    Listen, are we helpless? Are we doomed to do it again and again and again? Have we no choice but to play the Phoenix in an unending sequence of rise and fall? Assyria, Babylon, Egypt, Greece, Carthage, Rome, the Empires of Charlemagne and the Turk. Ground to dust and plowed with salt. Spain, France, Britain, America—burned into the oblivion of the centuries. And again and again and again.

    Are we doomed to it, Lord, chained to the pendulum of our own mad clockwork, helpless to halt its swing?

    A cry for sanity in our silent night of madness

    You =can= and I have made one to work again. But... do you really want to?
    The one I tinkered with is no longer "technically" a wall wart. :-)

    After opening it up I see it will not be too hard to repair. A bit of solder should do it. I ordered another just to have a spare. I have several 9 and 12 V wall warts but I like having the 7.5 as it works on all my Parallax boards without worrying about over powering anything.
