    Oscilloscope Question

    If you are getting a full wave AC signal then there are a couple possibilities. 1. As duke37 said, the rectifier is bad. 2. The battery charger is not grounded and you are seeing the AC from the floating ground. Make sure both charger and scope are grounded. Posting a picture might help.

    Battery Fail and Pop?

    It could very well be. I really thought a cap blew in the O-scope but I have not observed any change. Also thought I would have smelled something. Really strange.

    Battery Fail and Pop?

    I was sitting at my work bench yesterday when I heard a very loud pop (my wife even heard it in the other room). It very much sounded like a capacitor or IC had gone critical. However I only had my oscilloscope and laptop running at he time. I could not smell or see any smoke and everything...

    How do I figure out what is jamming the RF signal in my garage

    To start eliminating sources of possible interference turn off the power to different rooms and see if that fixes it. It's amazing how much RF garbage some appliances can produce. I had a satellite receiver that put out a very strong signal right at 146.75mHz (ham radio repeater frequency). It...
