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

[edit] Explanation

Another fine example of nerd sniping. There are pieces of circuit diagrams, road maps, chemical diagrams, and other things all mixed in. Explanations for each below!

Image Fragment Image Location Description
circuit diagram-019-025-106-037-scale.png 106x37 @ 19,25 A map scale. Lists kilometers and miles as equivalent. And makes the diagram many miles wide.
circuit diagram-015-062-040-085-antenna.png 40x85 @ 15,62 An antenna. Typical of radio receivers or transmitters.
circuit diagram-053-060-041-087-inductor.png 41x87 @ 53,60 A coil or inductor. Normal, but unlabeled.
circuit diagram-107-086-085-093-cloverleaf.png 85x93 @ 107,86 A cloverleaf interchange or junction is a feature of road networks that does not belong in a circuit diagram. Of course, other types of junction are important in electronics.

A cloverleaf junction has previously been used in comic: 253: Highway Engineer Pranks

circuit diagram-184-012-087-063-battery.png 87x63 @ 184,12 A battery. The voltage of square root of two is strange, but getting about 1.41412... volts is not unheard of. The marked polarity is also the reverse of what is implied by the symbol (where the larger terminal is positive).
circuit diagram-187-110-094-071-resister.png 94x71 @ 187,110 A 120 ohm resistor is normal enough. "Or to taste" is odd for a circuit diagram and more like instructions from a recipe, e.g., "1 tbsp tomato purée, or to taste".
circuit diagram-283-050-090-063-switch.png 90x63 @ 283,50 A normal switch, with a notation to glue it open. Reminiscent of the MAGIC/MORE MAGIC switch.
circuit diagram-337-101-069-064-transisitor.png 69x64 @ 337,101 A bipolar PNP transistor, except that it has two emitters and no collector.
circuit diagram-052-141-079-107-compass-points.png 79x107 @ 52,141 Compass points. A map feature, not a circuit feature.
circuit diagram-415-018-063-058-resister.png 63x58 @ 415,18 A normal resistor, labeled with color code. Brown-Blue-Orange would be 16000 ohms. Resistor color codes are for reading the value on the physical device itself. They would not normally be shown on the circuit diagram, where it's much easier to just write the number, e.g. 16K.
circuit diagram-517-014-042-032-diode.png 42x32 @ 517,14 A normal diode.
circuit diagram-615-055-073-074-666timer.png 73x74 @ 615,55 A chip. The normal timer is a "555". "666" would be the number of the beast in Rev. 13:18. The pin connected to "?" is the CTRL pin on a normal 555 timer, which would typically be connected to ground (via a decoupling capacitor) if used at all; the implication here seems to be that it would be connected directly to Hell itself.
circuit diagram-632-138-069-041-bat.png 69x41 @ 632,138 A Batman logo.
circuit diagram-650-211-075-071-squirrel.png 75x71 @ 650,211 A squirrel. What it does as a circuit element is unsure.
circuit diagram-606-165-054-053-inductor.png 54x53 @ 606,165 A coil or inductor, or a spring symbol in Physics force diagrams, probably the latter as it is labeled with an 11-kilogram mass.
circuit diagram-538-209-099-059-generator.png 99x59 @ 538,209 A 240-volt AC generator (or other power source).
circuit diagram-483-186-111-103-shorted-generator.png 111x103 @ 483,186 A shorting wire around a generator. The label reads "Omit this if you're a wimp." If this wire is included, it will quickly melt - or worse.
circuit diagram-419-078-057-075-scarab-beetles.png 57x75 @ 419,78 A jar of scarab beetles.
circuit diagram-482-047-028-044-variable-resister.png 28x44 @ 482,47 A variable resistor with center tap. Normally, there would be an arrowhead on the center tap.
circuit diagram-507-053-022-027-capacitor.png 22x27 @ 507,53 A normal capacitor.
circuit diagram-577-318-096-062-magic.png 96x62 @ 577,318 "Magic Smoke" is the legendary stuff inside a chip that comes out when it fails.
circuit diagram-669-315-051-066-frayed-wires.png 51x66 @ 669,315 Some frayed or dangling wires.
circuit diagram-567-392-058-048-buoy.png 58x48 @ 567,392 An object which is either a float used in fishing, a Tippe top, or perhaps a mine.
circuit diagram-458-336-111-086-moral-rectifier.png 111x86 @ 458,336 A bridge rectifier, which would normally turn alternating current at the top and bottom into direct current on the left and right. In this case, it is labeled as a "moral rectifier". This is presumably a play on the idea of moral rectitude – it makes your circuit more moral. Why this matters in a circuit is unclear.
circuit diagram-423-259-080-085-warm-front.png 80x85 @ 423,259 A warm front is a feature on a synoptic weather map.
circuit diagram-190-199-054-052-battery.png 54x52 @ 190,199 A normal 50-volt battery.
circuit diagram-173-200-089-056-shorted-battery.png 89x56 @ 173,200 A battery is grounded on both sides. Something will melt or burn out quickly, unless these are separate "earth ground"s, in which case the ground might get a bit cooked.
circuit diagram-259-198-174-025-pull-wire.png 174x25 @ 259,198 Text reads "Pull this wire really tight". This kind of physical-property issue may indicate a high-frequency radio device. Or, given the absurdity of the context, it's a silly reference to a "high tension wire."
circuit diagram-141-211-041-091-3-8-inch.png 41x91 @ 141,211 A specified 3/8-inch separation. This probably indicates a carefully controlled capacitance issue. Also contradicts the scale of the drawing, by which the distance shown would be about 0.8 miles or 0.8 km.
circuit diagram-173-309-092-059-eel.png 92x59 @ 173,309 An electric eel. This may be an effective power source in the circuit.
circuit diagram-266-307-035-041-resistor.png 35x41 @ 266,307 A normal resistor.
circuit diagram-222-358-034-029-capacitor.png 34x29 @ 222,358 A normal capacitor.
circuit diagram-130-335-044-040-resistor.png 44x40 @ 130,335 A normal resistor, labeled "ë". This may be a play on Euler's Number, which doesn't normally have an umlaut. Alternatively instead of being an umlaut it may indicate the second derivative derivative of e with respect to time in Newton's notation, in which case, as e is a constant, the resistance of this element is zero.
circuit diagram-065-249-061-092-blender.png 61x92 @ 65,249 This appears to be a blender.
circuit diagram-020-342-115-073-arduino.png 115x73 @ 20,342 An arduino, labeled "Arduino, just for blog cred". May refer to the fact that inexpensive, easy-to-integrate single-board computers like the arduino, which have contributed to the rise of Maker_culture, are used and discussed frequently in that culture, and the use of one might impress readers. The comment implies that an arduino is not otherwise needed in this circuit, although it is necessarily hard to tell, given the other components of the circuit.
circuit diagram-039-423-118-082-meca.png 118x82 @ 39,423 A chip labeled "Most expensive chip available". The small curve at the top is a part of the packaging designed to show its orientation.
circuit diagram-159-428-091-050-neck-strap.png 91x50 @ 159,428 Labeled "Neck Strap". Perhaps a piece of torture equipment or indicating that the circuit is part of an electric chair?
circuit diagram-147-480-110-088-switch.png 110x88 @ 147,480 A switch labeled "Hire someone to open and close switch real fast." Possibly meant to perform the function of an oscillator in a more hackish manner and the reason for the neck strap.
circuit diagram-273-498-061-064-resistor.png 61x64 @ 273,498 A 5 ohm resistor labeled "(decoy)". One end is not attached to anything. Perhaps this indicates wishful thinking that electrons might be tricked into entering this part of the circuit despite the fact that there's nowhere for them to go?
circuit diagram-307-453-103-056-tongue.png 103x56 @ 307,453 A pair of contacts, labeled "Touch Tongue Here". Could be referring to the practice of daring someone to touch their tongue to the contacts of a 9V battery.
circuit diagram-301-270-045-045-frown.png 45x45 @ 301,270 A frowny-face. See the float/mine.
circuit diagram-294-311-128-124-IC.png 128x124 @ 294,311 A small integrated circuit. The lower gate is an inverter, wired as a free-running oscillator. The upper gate is an XOR wired to act as either a free-running oscillator or a latch. Since the XOR will be slower than the inverter, the overall output of the upper gate is probably very chaotic. Two "input" wires are not connected at all. An additional wire is attached to the top with hot glue. This last wire probably acts to control static electricity and leakage.
circuit diagram-302-235-091-025-curve.png 91x25 @ 302,235 A caution sign at a curve. Another road feature in the circuit.
circuit diagram-401-455-067-068-CH3.png 67x68 @ 401,455 A methyl group (chemistry) attached to a corner. If the circuit were an organic chemical, it would be reasonable to find a number of these.
circuit diagram-453-167-043-093-baloon.png 43x93 @ 453,167 A balloon, possibly blowing in a breeze.
circuit diagram-572-068-022-043-inductor.png 22x43 @ 572,68 A coil or inductor.
circuit diagram-508-096-042-020-inductor.png 42x20 @ 508,96 A coil or inductor.
circuit diagram-534-061-022-031-ground.png 22x31 @ 534,61 A ground connection.
circuit diagram-472-049-134-140-solderr-blob.png 134x140 @ 472,49 A solder blob covering a portion of the circuit. Normally, this would not be part of the circuit diagram, but a mistake in building the circuit.
circuit diagram-493-443-207-158-res-rats-nest.png 207x158 @ 493,443 A rats nest of 1 ohm resistors. It is labeled "Oh, so you think you're such a whiz at EE201?" Calculating the effective resistance of this is what the title text refers to. It appears to work out to 0.75800964845 ohms.
circuit diagram-362-531-151-167-arena.png 232x200 @ 315,533 An arena, with a few bodies in it. Note the direction of movement enforced by the surrounding diodes, "two men enter, one man leaves"
circuit diagram-569-653-047-051-resistor.png 47x51 @ 569,653 A "pi" ohm resistor.
circuit diagram-610-655-075-070-generator.png 75x70 @ 610,655 A 500-volt AC generator. The wiring to the right shorts out this generator.
circuit diagram-481-682-085-064-ground.png 85x64 @ 481,682 A ground connection, labeled "Bury deep, but not too deep". This type of ground connection is called an "earth ground" The "too deep" part might be a reference to Moria in Lord of Rings. The dwarves dug too deeply and disturbed a balrog. See also comic 760.
circuit diagram-017-610-075-073-fishhook.png 75x73 @ 17,610 A ground connection at the end of a curve, looking like a fishhook. Means perhaps "earthed down under", i.e., Australia or the southern hemisphere.
circuit diagram-206-662-066-045-yarn.png 66x45 @ 206,662 A length of "wire" is labeled "yarn". This probably makes it a terrible conductor.
circuit diagram-102-590-093-088-fluxcapacitor.png 93x88 @ 102,590 The flux capacitor from Back to the Future.
circuit diagram-138-685-054-024-I95.png 54x24 @ 138,685 A road sign for "I-95". Interstate 95 is the main north-south highway on the east coast of the United States, running from Maine to Florida.
circuit diagram-012-713-134-036-tothesun.png 134x36 @ 12,713 A connection labeled "To center of Sun". A 93-million-mile circuit is rather large, but...
circuit diagram-031-753-144-177-rats-nest.png 144x177 @ 31,753 A rat's nest of wires. Everything winds up being connected.
circuit diagram-022-513-097-061-esf.png 97x61 @ 22,513 A label reading "Electrons Single File". If this happens, the resistance in this section of wire would be rather high.
circuit diagram-256-619-029-039-ground.png 29x39 @ 256,619 A ground connection.
circuit diagram-589-600-058-046-vibrator.png 58x46 @ 589,600 A vibrator, which would be a motor with an off-center weight attached to it.
circuit diagram-532-779-074-052-motor.png 74x52 @ 532,779 A motor, labeled "To Scale". This indicates that the physical size and shape of the motor must match the size of the parts around it, or is consistent with the specified scale of the drawing.
circuit diagram-662-822-073-109-holy-ground.png 73x109 @ 662,822 A ground connection, in a beaker labeled "Holy Water".
circuit diagram-197-740-048-055-speed.png 48x55 @ 197,740 A sign indicating a speed limit of 55 MPH. This is a rather typical road sign, but inappropriate for a circuit diagram.
circuit diagram-238-706-100-116-flipflop.png 100x116 @ 238,706 A pair of NOR gates wired as a SR (set-reset) flip-flop. The label reads "May use an actual sandal instead", which is a play on the meanings of the term "flip-flop".
circuit diagram-322-708-070-054-holdingpen.png 70x54 @ 322,708 Something that could be the side view of a fence, labeled "Holding Pen".
circuit diagram-339-777-042-049-knot.png 42x49 @ 339,777 A simple overhand knot. Also looks like a pretzel, which would have pretty high resistance.
circuit diagram-191-889-149-033-ecg.png 149x33 @ 191,889 This appears to be an electrocardiograph trace.
circuit diagram-223-826-082-068-photodiode.png 82x68 @ 223,826 A photodiode, labeled "Tear Collector". A photodiode is a light-sensing device.
circuit diagram-373-859-049-068-lamp.png 49x68 @ 373,859 A lamp. This is not the symbol used in electrical circuits, but a drawing of a lightbulb.
circuit diagram-450-887-065-032-inductor.png 65x32 @ 450,887 A coil or inductor.
circuit diagram-537-847-120-072-inductor.png 120x72 @ 537,847 A coil or inductor, labeled "Take off shirt while wiring this part. Ooh, yeah, I like that."
circuit diagram-504-860-034-041-resistor.png 34x41 @ 504,860 A resistor labeled "?". Presumably this means the resistance is unknown.
circuit diagram-459-828-055-038-resistor.png 55x38 @ 459,828 A resistor labeled "YES". Likely another improper unit - a reference to boolean values YES (TRUE) and NO (FALSE). Depending on the limits of a circuit, a resistor would still have a YES boolean value. Possibly indicating that this is a real resistor, as opposed to the one above it in the circuit, labeled "not a resistor."
circuit diagram-389-774-058-053-resistor.png 58x53 @ 389,774 A resistor labeled "8mm".
circuit diagram-443-747-093-084-resistor.png 93x84 @ 443,747 A resistor labeled "Not a resistor; wire just does this". This may reflect the fact that any wire has a certain amount of resistance just by being a wire, or it may be that the wire is physically bent into a zig-zag shape.
circuit diagram-415-863-082-024-unsure.png 82x24 @ 415,863 A symbol for a feedthrough capacitor, labeled "3 Liters". Probable word-play on "capacity/capacitor." Also similar to the symbol for an orifice or flow restriction used on plumbing or hydraulic diagrams, in which case the "3 Liters" might mean 3 liters per minute or per second.

Discussion

So, is the arena a new kind of comparator or something? Davidy22[talk] 13:28, 18 February 2013 (UTC)

11:13, 10 April 2013 (UTC)11:13, 10 April 2013 (UTC)Jh6p (talk) The 3 liter capacitor could also be a ball approximately 6 inches in diameter if the seams on the ball were similar to the seams on a basketball. Perhaps a volleyball?

"A squirrel. What it does as a circuit element is unsure."

Perhaps an allusion to a squirrel cage? Wwoods (talk) 18:51, 22 April 2013 (UTC)

The shape of the squirrel's tail reminds me of a hysteresis curve, although this is admittedly a bit of a stretch. —Scs (talk) 16:02, 17 November 2013 (UTC)

The 'to scale' motor would be about half a mile wide. Powering the rabbit on Gaia's vibrator (also included)? --StarChaser Tyger (talk) 08:40, 22 June 2013 (UTC)

I beg to differ on the flux capacitor thing, as cool as it sounds. Since it is right above the I-90 notation, it is more likely a fork in the road (notice the road stripes indicating that you can pass at any point in the fork). 97.87.12.114 02:15, 24 June 2013 (UTC)

Oh, I'm pretty sure it's a flux capacitor. Compare some of these images. Yes, there are several road references in this comic, but an electronic reference (especially to a fictional electronic component!) makes more sense. Also I've never seen a Y-shaped highway intersection that looked quite like that (and especially not on an interstate). —Scs (talk) 14:52, 17 November 2013 (UTC)

I have wasted 4 hours on the puzzle, and after wasting 9 pages of A5 paper, the resistance of that terrible resistor mess worked out to be exactly 25265/33783 ohm, or about 0.74786135 ohm. --KopaLeo 199.48.226.89 15:16, 27 June 2013 (UTC)

I think that the "fishing float" might actually be a picture of an ordinary push switch (similar to foot switches used on standard lamps). 87.194.171.29 16:12, 10 July 2013 (UTC)

Isn't the "YES" resistor a reference to the anecdote of how John Lennon and Yoko Ono met? That's what I thought when I saw it, but then, I kinda like The Beatles a bit. 200.70.22.74 12:27, 16 September 2013 (UTC)

I think the attempt to explain every single piece of the comic is rather silly. The humor largely draws from the absurdity of the diagram, and that can probably be summarized without going into detail about the possible references of each individual component. 199.27.130.180 03:22, 26 November 2013 (UTC)

I disagree. The joke works on multiple levels, both the absurdity of the circuit, and the smaller parts of which it is comprised. Hydroksyde (talk) 02:40, 21 April 2014 (UTC)

I concur with KopaLeo - I got the same answer for the resistance of the grid of resistors - about 0.748 when rounded. What a problem! --techdude 108.162.215.65 20:45, 1 January 2014 (UTC)

I feel like I should point out that putting a ground connection in holy water probably creates Holy Ground 108.162.212.197 11:36, 26 March 2014 (UTC)
