Flux Capacitor -VERY EASY TO BUILD

make a Back To The Future  *Flux Capacitor* but dont want to spend 300$ or spend any money? well i know you want to read this so.
i made a BTTF Flux Capacitor for free, by using an old pc as my *parts*
its wired up that it runs off the 12V car battery in my golf.

total cost >> FREE!

Step 1: Parts

1 or 2 old pcs,
multimeter,
snips
solder iron,
plywood,
3 old spark plugs
plastic pipe
screwdriver
black rattle can

if you are like me you will have a least one old pc around the place, with windows 3.1 or 95 or something like that or have come a cross a old unwated pc and you get it for free  :D

well thats just me...

fun part
taking the old pc apart
stripping the old pc down you will notice there is  leds on:

>>the cd rom drive,
>>floppy drive,
>> front light for hard drive in use
>> sometimes a reboot led beside the reboot button
and the Start/Power button

now as it turns out each of them can have different colours,
ie, hard disk can be orange,
flop disk can be green or orange,/yellow
cd rom is usually green,
hard disk and restart can be red or orange...

so usually there will be Green Red Orange/ yellow
you will need 4 LEDS

reason for 4 leds is  you are running a 12V batter power supply, and the pc operates at  0-5Vs
but that does not mean the LEDs are 5v leds, if they are only coming on for a second, they can be 3v leds

so for safety to prevent them from burning out we are going with 4, plus,  more leds = more light

just to note, more leds = more lights but more leds means the leds are not as bright but this is good as you dont want extremely bright leds in the back of your car

for this step you should have 4 leds its best if they are all the same colour or near enough. to being the same colour  (ie orange and red is ok)

what i did was got 2 old pcs and got 4 Green LEDS

HAHAHA!!!! THUMBS UP
This is really cool, but I can't help but think it needs a little bit more decoration. Some little metal pluggy bits would make this look awesome. Well done though, this is indeed an easy to build flux capacitor!

oh like its just for show, as a bit of a joke. it cost me more a less nothing to make, and had it wired up in the back of the golf for a while. the next thing i wanted to do was wire it up to the radio signal so the lights would flash intime with the music., but ya your dead right a bit more decoration would finish it off nicely

Ohm's Law says that R=V/I, you got it backwards...

Moreover, there are no LEDs rated at 5 Volts or 12 Volts. Most LEDs have a threshold voltage of about 2 Volts but have almost no resistance. LEDs have a Reverse Breakdown Voltage of a few Volts so if you hook them up to AC without a power diode in series you'll burn them up, assuming that they didn't explode because of the huge current in the positive half-wave. LEDs are usually connected to a DC power supply. A 330 ohms resistor is good for 5 Volts DC. 1 kOhm for 12 VDC. Definitely not a good instructable.

why dont you just go make your own, and we will rate yours! if you have nothing positive to say shut up! i used LEDS 4 leds in series so i didnt have to use resisters

How are you getting the 1.21 jiggawatts to power it?
