I know it was easier for me to do a quick look at the "most recent 25" from the front page and give input to those I could say anything about.
But yourMOM is correct about one thing, 95% of the questions are ones that have been answered 95 times already.
Seriously:
off and on 3 times = FRAG = check your soldering, and I don't care how good you think you did, CHECK YOUR SOLDERING!!! You don't need to ask if it could be anything else.
And yes, doing this CAN wreck things, and if you wrecked a box, join the club, you're screwing around with sensitive equipment! Try an apendectimy on you aunt and see how that goes and then post to a forum saying "I did everything the way the tutorial said, but she kept bleeding... your scalpel sux!"
Ok, sorry... getting off topic I know... <smile>
