| Circuit Diagram |
 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. |
Explanation
|
This explanation may be incomplete or incorrect. If you see a way to improve it, edit it! Thanks. |
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 |
|---|---|---|
|
106x37 @ 19,25 | A map scale. |
|
40x85 @ 15,62 | An antenna. Typical of radio receivers or transmitters. |
|
41x87 @ 53,60 | A coil or inductor. Normal, but unlabeled. |
|
85x93 @ 107,86 | A feature of road networks that does not belong in a circuit diagram. |
|
87x63 @ 184,12 | A battery. The voltage of square root of two is strange, but getting about 1.41412... volts is not unheard of. |
|
94x71 @ 187,110 | A 120 ohm resister is normal enough. "Or to taste" is odd. |
|
90x63 @ 283,50 | A normal switch, with a notation to glue it open. Reminiscent of the MAGIC/MORE MAGIC switch. |
|
69x64 @ 337,101 | A bipolar PNP transistor, except that it has two emitters and no collector. |
|
79x107 @ 52,141 | Compass points. A map feature, not a circuit feature. |
|
63x58 @ 415,18 | A normal resistor, labeled with color code. Brown-Blue-Orange would be 16000 ohms. |
|
42x32 @ 517,14 | A normal diode. |
|
73x74 @ 615,55 | A chip. The normal timer is a "555". "666" would be the number of the beast. |
|
69x41 @ 632,138 | A batman logo. |
|
75x71 @ 650,211 | A squirrel. What it does as a circuit element is unsure. |
|
54x53 @ 606,165 | A coil or inductor, labeled as an 11 kilogram mass. |
|
99x59 @ 538,209 | A 240 volt AC generator (or other power source). |
|
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. |
|
57x75 @ 419,78 | A jar of scarab beetles. |
|
28x44 @ 482,47 | A variable resister with center tap. Normally, there would be an arrowhead on the cetern tap. |
|
22x27 @ 507,53 | A normal capacitor. |
|
96x62 @ 577,318 | "Magic Smoke" is the legendary stuff inside a chip that comes out when it fails. |
|
51x66 @ 669,315 | Some frayed or dangling wires. |
|
58x48 @ 567,392 | This appears to be a float used in fishing |
|
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". |
|
80x85 @ 423,259 | A weather map feature. |
|
54x52 @ 190,199 | A normal 50 volt battery. |
|
89x56 @ 173,200 | A battery is grounded on both sides. Something will melt or burn out quickly, unless these are seperate "earth ground"s, in which case the ground might get a bit cooked. |
|
174x25 @ 259,198 | Text reads "Pull this wire really tight". This kind of physical property issue may indicate a high frequency radio device. |
|
41x91 @ 141,211 | A specified 3/8 inch separation. This probably indicates a carefully controlled capacitance issue. |
|
92x59 @ 173,309 | An electric eel. This may be an effective power source in the circuit. |
|
35x41 @ 266,307 | A normal resistor. |
|
34x29 @ 222,358 | A normal capacitor. |
|
44x40 @ 130,335 | A normal resistor, labeled "ë", This may be a play on Euler's_Number, which doesn't normally have an umlaut. |
|
61x92 @ 65,249 | This appears to be a blender. |
|
115x73 @ 20,342 | An arduino, labeled "Arduino, just for blog cred." |
|
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. |
|
91x50 @ 159,428 | Labeled "Neck Strap". Perhaps a piece of torture equipment? |
|
110x88 @ 147,480 | A switch labeled "Hire someone to open and close switch real fast." |
|
61x64 @ 273,498 | A 5 ohm resistor labeled "(decoy)". One end is not attached to anything. |
|
103x56 @ 307,453 | A pair of contacts, labeled "Touch Tongue Here". |
|
45x45 @ 301,270 | A frowny-face. |
|
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 hot glue'ed to the top. This last wire probably acts to control static and leakage. |
|
91x25 @ 302,235 | A caution sign at a curve. Another road feature in the circuit. |
|
67x68 @ 401,455 | A methyl group (chemistry) attached to a corner. If the circuit where an organic chemical, it would be reasonable to find a number of these. |
|
43x93 @ 453,167 | A balloon, possibly blowing in a breeze. |
|
22x43 @ 572,68 | A coil or inductor. |
|
42x20 @ 508,96 | A coil or inductor. |
|
22x31 @ 534,61 | A ground connection. |
|
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. |
|
207x158 @ 493,443 | A rats-nets of 1 ohm resisters. 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 works out to 0.93986 ohms. |
| File:circuit diagram-315-533-232-200-arena.png | 232x200 @ 315,533 | An arena, with a few bodies in it. Note the direction of the diodes, "two men enter, one man leaves" |
| File:circuit diagram-311-599-042-035-diode.png | 42x35 @ 311,599 | A diode |
| File:circuit diagram-512-604-037-026-diode.png | 37x26 @ 512,604 | A diode |
| File:circuit diagram-418-703-029-031-diode.png | 29x31 @ 418,703 | A diode |
|
47x51 @ 569,653 | A "pi" ohm resistor. |
|
75x70 @ 610,655 | A 500 volt AC generator. The wiring to the right shorts out this generator. |
|
85x64 @ 481,682 | A ground connection, labeled "Bury deep, but not too deep". This type of ground connection is called an "earth ground". |
|
75x73 @ 17,610 | A ground connection at the end of a curve, looking like a fishhook. |
|
66x45 @ 206,662 | A length of "wire" is labeled "yarn". This probably makes it a terrible conductor. |
|
93x88 @ 102,590 | The flux capacitor from Back to the Future |
|
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. |
|
134x36 @ 12,713 | A connection labeled "To center of Sun". A 93 million mile circuit is rather large, but ... |
|
144x177 @ 31,753 | A rats nets of wires. Everything winds up being connected. |
|
97x61 @ 22,513 | A label reading "Electrons Single File". If this happens, the resistance in this section of wire would be rather high. |
|
29x39 @ 256,619 | A ground connection |
|
58x46 @ 589,600 | A vibrator, which would be a motor with an off-center weight attached to it. |
|
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. |
|
73x109 @ 662,822 | A ground connection, in a beaker labeled "Holy Water". |
|
48x55 @ 197,740 | A speed limit 55 MPH sign. |
|
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". |
|
70x54 @ 322,708 | Something that could be the side view of a fence, labeled "Holding Pen". There might be a small figure inside... |
|
42x49 @ 339,777 | A simple overhand knot. |
|
149x33 @ 191,889 | This appears to be an Electrocardiograph trace. |
|
82x68 @ 223,826 | A photodiode, labeled "Tear Collector". A photodiode is a light sensing device. |
|
49x68 @ 373,859 | A lamp. |
|
65x32 @ 450,887 | A coil or inductor. |
|
120x72 @ 537,847 | A coil or inductor, labeled ""Take off shirt while wiring this part. Ooh, yeah, I like that." |
|
34x41 @ 504,860 | A resistor labeled "?". Presumably this means the resistance is unknown. |
|
55x38 @ 459,828 | A resistor labeled "YES". |
|
58x53 @ 389,774 | A resistor labeled "8mm". |
|
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. |
|
82x24 @ 415,863 | A symbol similar to two electrolytic capacitors back to back, labeled "3 Liters". |

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?
