    It would be somewhat easier to make BEAM Bots and stuff like that with it, seeing as it has long leads on it :)

    Does anyone have a pic of the round 555 package?

    I just did a google image search and could not find one.

    Nope sorry, not off-hand. It looks like a metal can with an 8-pin DIN type pattern.

    -BaC
    I will look around, but I am not sure if I will get anything.

    I bet they're worth a bit of money.

    I've got some metal can µA741s but I've never seen a metal can NE555 before.

    I have build a circuit (shown in the attachment) from one of the tutorials above and am now playing around with the timings by changing the values of R1 and R2. What I want ideally is a short on time (say 1 second or less) and a long off time (say 5 seconds or more). But at the moment I seem to only be able to increase or decrease them both - any ideas?

    If you just want to power an LED then connect it from pin 3 to +V instead of 0V.
