    I’m asserting it’s done, and asking if you too can figure it out.

    I should have picked another day. It’s the 2nd now in Aus, but I’ll come back tomorrow
    It is what I say it is I swear.

    That’s awesome. I just need to make a YouTube video right now 10 hours ahead UTC.
    This should be a pretty good April Fool’s joke.

    I’m disappointed
    I guess I’ll have to spill the answer tomorrow.

    I am a total noob, but I feel such cleverness deserves a guess - even if only to prove how far superior your skills. I am unwilling to just shrug and wait for you to reveal your skill without so much as voicing the consideration I have given - not so much a joke, but puzzle - you have provided.

    I will guess that there is some capacitance in the circuit and that you use some application of the RCTime constant as a reference; different clocks would, I think, reveal the clock speed by the timer values measured when charging and discharging a capacitor from a known voltage. I take my guess from watching the LED (which, I believe has a capacitance associated - and conveniently a resistor in series) which is slow to start - I'm hoping, because it is busy measuring...

    Interesting idea, but not tested by me so I don’t know if it would work

    The virtue in what I’m doing is someone might come up with a better way,
    and at the moment I would appreciate that.
    It’s not genius trust me, you’ll find out. Someone is close on another forum.

    I know of the 4MHz RC clock. What’s the other?
