    Everyone knows and loves the old LM3909... there are hundreds of projects
    out there for them, including BEAM robots and such. Only they're getting
    pretty hard to find.

    I checked through a broker and found that there are at least a couple of
    sources with more than a thousand on hand, but frankly I think those guys
    are mostly scum, and they always ask exorbitant prices.

    So I'm hoping to find a source directly that could sell at least a few
    hundred at a reasonable price. I'm willing to buy up to a couple thousand
    if they're cheap enough.

    If you've got some, or know where I can find some, please contact me by

    What do modern LED blinkers use? (the kind in grocery stores)

    Last time I needed something like that, I ended up using
    a PIC.

    Tin Men, an excerpt from the plot summary:

    Bill "BB" Babowsky (Richard Dreyfuss) is about to buy a Cadillac. A
    car salesman takes him in his office to close the deal. Babowsky,
    himself a salesman, makes it clear that he doesn't want to hear any
    sales tricks. "I really don't want you to hustle me," BB tells the car
    salesman. "I hate that."

    The salesman asks BB how much he's willing to pay and BB bristles.
    "You know you're doing it already," he tells the salesman. "You're
    trying to hustle me. Why don't you just tell me how much you want to
    sell it for. Then I'll tell you whether or not I'll pay it, and then
    we won't have to get into this hustle thing."

    The car salesman denies he's pulling a hustle and says he's just
    trying to find out how much BB wants to pay. "Okay," says BB. "Four
    dollars." The dealer can't believe it. "What do I really want to pay?"
    BB asks him. "I want to pay nothing. . ."
