    Watching this fine woman explain the 555 timer and board setup turns me on.

    I am trying to built an "vehicle speed checker" model for my engineering project submissions,
    So you can tell me what the cost of this model in INR currency from your opinion,
    please tell me.

    a clock circuit, and a transistor and another LED, politician circuit :p

    is it possible to build a variable frequency sine wave generator using a 555 timer circuit?

    Why do people insist on putting music behind a video where someone is talking? Really distracting.

    what is the formula of A stable operation? I'm trying to achieve 500ms On state and 4 second off state. I'm using 3.7V operation and have a 120mA drain at the pnp 3906 which is driving the LED's. (6x20mA =120mA) so I'm using 1K 100K at 3.3uf and it's close but the on state isn't working quite right. My timing seems to be effected by the current drain of the pnp which is pulling the CR2032 voltage down changing the timing. How do you compensate for this to create the stable 500ms On 4sec off state? Thanks

    Great vid & advice on using the wires over jumpers for final version, not just for aesthetics & transparency, but also for the practical effect on the circuit itself (less resistance from all the excess cable length). ??

    I've understand the 555 first time…But still I have watched this video many times …I don't know why?

    But then i thought "i gotta get back on a subject before i post something stupid".
    Oh well. I can always delete it if she dont like it.
