0730: "Circuit Diagram"

Postby hthall » Wed Apr 21, 2010 3:59 am UTC

Title-text: I just caught myself idly trying to work out what that resistor mass would actually be, and realized I had self-nerd-sniped.

I'm NOT going to analyze this . . . must resist . . .

(The title-text gives away what he's doing, here.)
Look at me, still talking when there's Science to do.

...I think this one deserves my first "meh."

Just a bunch of half-assed "I've taken circuit design" in-jokes illogically strung together.

The answer is that the circuit bursts into flames because there's a 50V source with both sides connected to ground.

EDIT: And some AC sources with the ends hooked together.

Anyone who gets the arena joke is definitely a nerd.

Most of the diagram is quite bizarre but I definitely lol'd at the title-text.

It's not supposed to mean anything; it's just a fake circuit design made out of nonsense.

Basically it's the electrical engineering equivalent of this little beauty.

Yes, but not in series with the magic smoke, so it's safe. (Also notice the "if you're a wimp" challenge.)

I still got distracted that the blender was neither a Vitamix nor a Blendtec and also had no handle (how annoying to try and use one that way).

When that happens to me I feel the need to Google and Wikipedia enough information until I understand the jokes. I like it because I find myself getting smarter as a result. It may be hard with this one since pictures are hard to Google.

Obviously, this circuit would never work without I-95 South eventually turning into 93 North.

And a 240 VAC source connected to itself and the ground-side of the 50 VDC supply and the... I'll stop.

Does anyone know what the symbol with the circle and the squiggly line represents? That's not an aspect of a circuit diagram that I recognize and I can't find anything that looks like that in a quick Google search. There are at least two of them in the diagram, one next to the "omit this if you're a wimp" note and another next to the Pi ohm resistor.

Also, while we're on the subject cool random fact: that I've heard by word of mouth but never seen in a reliable source. Although the terminology goes diode, triode, tetrode, pentode, originally diodes were not called that because they had two wires going in but rather from "dia" and "ode" from the Greek for "through path." (I suspect this is true because the diode term was used long before there were triodes).

I wonder if this circuit can really put 1.21 gigawatts through that flux capacitor there.

The squiggly line thing is an AC source

I've never taken Physics E&M, but I do know some of the symbols that pop up in the diagrams.

That may be why my favorite part of the diagram is "Not a resistor; wire just does this."

This has to be the most random comic I've seen yet...

At first I was thinking it might be like a circuit-diagram representation of Randall's personality/mind or something, but then I scrolled down and realized that it's waaaaay too random for that! :roll:

The thing I most identified with here was the "Arduino, for blog cred" bit. :mrgreen:

The lack of a particular observation galled me so much that I created an account to post it.

Anyone see the "1 mile" scale bar at the upper left corner? This thing is HUGE.... :shock:

Why is there a North, Five, East and West sign? Where's south? Why is there a balloon? So many questions.

No. It may help to note that there are two diodes allowing current to go into the arena, but only one allowing it to leave.

Anyone figured out the equivalent resistance of the crazy mess of resistors? should be pretty simple after a couple Delta-Y transforms. I'll probably work it out on the train tomorrow.

I thought it was a reference to the coliseum.
I also noticed this whole thing looks like it's designed to power a light bulb. Randall needs to play some gizmo's and gadgets, because this circuit isn't a bright idea.
