You know that you're really a nerd when ...

[JohnS_AZ]

... you vacuum up a slug tuned coil from the living room carpet and have absolutely no idea where it came from.

(just for fun, add you own)

[TheWelly888]

...take a look in the scrapped pcb bins at work for anything interesting or potentially useful.

...strip down scrapped medical equipment or assemblies for the same thing. ( I got a nice looking strain gauge assembly and a small stepper out of a syringe driver pusher assembly last week! )

...When you draw a schematic in pencil and then wonder what the actual resistances of the drawn resistors are (...because of the graphite)

.o:0|O|0:o.

[Time]

... when any explanation you give to anything in life always ends up relating back to control system theory.

[DJPhil]

. . . you very nearly wind up in a fight with your significant other because, "You were up all night and you've got glitter on your shirt!" after staying up late to salvage parts and cleaning out your solder sucker.

This one might work too, but it's probably not a nerd thing just a dumb me thing (ergonomics count).

. . . you throw out your back designing a PCB because you didn't move from your uncomfortable chair for eight straight hours.

At least I got my first SMD double sided design done. Must invest in a better chair.

[Polossatik]

.. you grab your tablet to google a receipt instead of using one of the numerous cookbooks in the kitchen...

[apex]

...you draw a schematic on paper with a pencil and stick parts with conductive epoxy to it.
...you see a gadget and start thinking of how to rebuild it using only the parts you have at home.
...you collect burned transistors.

[logictom]

...you take an internet connected device to the bathroom with you just to continue reading that new datasheet

[Kiriakos-GR]

My dad told me , that if I can not master an specific work , its best to not do it at all ..

Dad , you are a nerd !!   

[Excavatoree]

This is definitely nerdy, but it's not related to electronics:

When I was at the University, my friend and I went to an amusement park.  We computed the best ride based on the ride time to wait time ratio, as well as the "intensity" of the fun per ride.  My wive (then girlfriend) won't let us forget it.

you use MATLAB to convert images from .bmp to .jpg

your idea of a cool cocktail is anything drunk out of a metal cup with the positive terminal of a 5V cell phone charger soldered to it, the negative terminal is soldered to a piece of copper and held under the tongue(don't try this at home).

your idea of a cool cocktail is anything drunk out of a metal cup with the positive terminal of a 5V cell phone charger soldered to it, the negative terminal is soldered to a piece of copper and held under the tongue(don't try this at home).

you are considering trying it at home, anyway.

(hmm, maybe with a 3V or 1.5 v button cell.........Ah Ha - A cup with a battery holder built on the side.  One terminal connected to the metal cup, the other side pressing against the hand............)

[PetrosA]

You spend three whole evenings online looking for a crimp tool...

You take four multimeters to check the output of newly installed solar panels...

You've run out of people to talk to about test equipment and tools in person...

A customer asks you what you think about CFL bulbs and you're wondering how to explain CIE La*b*, metamerism and color rendering indexes...

[Rhythmtech]

When you have 6 VCR's that you picked up at garage sales and repaired sitting in the basement going pointlessly unused...

[Nermash]

When you're surfing ebay for test gear and googling reviews while all your colegues at work spend time on fb

[Neilm]

You probably are a nerd if you know PI to more places than 3.145.

You definatley are a nerd if you spotted the above value is wrong.


Neil

[marianoapp]

and a bigger nerd if you know how to calculate pi

[Mechatrommer]

you continue your project in your dream.

Nerd hat/pocket protector on, it's actually 3.1415927...  ;-)

...so that he could then give Pi as being 3.1415...999999 etc.

Pi is quite an incredible number considering that it contains, at some point, every conceivable string of numbers and that all numbers are equally statistically likely and distributed in a way that satisfies randomness.

It would not be surprising if everything were built upon this constant of periodicity.

More Pi anyone?

Actually I prefer  applePi ...

You check the EEVBLOG daily to see if Dave has posted any new equipment reviews....

[ModemHead]

... you consider buying "for parts or repair" test gear on eBay as part of your entertainment budget.

[david77]

...study the Wikipedia article about the worlds different power plugs in your lunch hour.

[Excavatoree]

You read this thread saying "yes, yep, done that, uh-huh...etc." Also, if you are surprised someone else does something.
