    Suggestions for winter electronics projects wanted

    One of the small projects in Electronics Class was a "Bird Chirper" You might combine several calls onto one board. One person in class accidentally called it a "Bird Chipper"! You could connect the Bird Chirper to a door entry switch (like a retail store) or to a doorbell button.

    Reversing polarity through signal from mouse switch

    This is all my fault ... I dragged up a 2 year old thread about reversing switches, and now we have "Battle of the All-Star Epts". It will be the Adept vs the Inept (so called.)

    Original way to use car radio as a garage radio

    This could be a dream. I take a 12 volt AM radio. I connect 2 lead acid batteries (6 volt each) in series with 4 gauge jumper cables. I use a C-clamp to attach the antenna to the window sill in the garage. Then I can listen to the radio in the garage just like Grandpa did. Maybe I am still...

    Need help wiring stereo jack to disconnect speaker

    To avoid GooGoo sales pitch, use this trick when searching an item: add a verb in front of the name of the thing you are searching. For example "using Amphenol stereo jack" or "connecting Amphenol stereo jack" or "testing Amphenol stereo jack".

    Confusion, Deliberate hacking, Guesses, Tests

    Are Deoxit contact cleaners worth the money?

    Deoxit D5 contact cleaner followed by Deoxit S5 shield is the new standard! My D5 ran out after several years and I was shocked by the new price, but I knew how good it was so I bought another tin. To save money I use smaller squirts, wait a bit, then add a bit of S5. Those other oil-based...
