    Now, for some real fun, take the same basic circuit, but hook up some of those solid-state ceramic heating/cooling tiles, so that it heats hot drinks and cools cool drinks, automatically.

    At last, a coaster for those of us who cannot perceive temperature!

    Coasters that detect hot and cold drinks. What a wonderful new technological breakthrough! Aren’t we fortunate to live in such times?

    Only one question: Why?

    Perfect to take along on those long flights!

    I love Windell’s use of analog circuits when other people would first try digital. This stands out in their awesome LED coffee table.

    A simpler (digital) route would be to configure two DS1821‘s (one for each LED), but they are $2.20 each. And that circuit wouldn’t look or act nearly as cool as the analog one!

    With regard to “Why” – why do you put pictures on coasters? It’s interesting to look at, offers a few moments of amusement, and has blinkenlights on it. Why not?

    At first I scoffed, but now I realize that
    the beauty in this lies in it’s uselessness.

    It’s still a neat little gadget.
