Dont look into the light to long! You might catch...
IF AFTER VIEWING THIS PAGE YOU EXPERIENCE INCREASED HEART RATE, COLD SWEAT, ANXIETY OR THE DESIRE TO SOLDER, YOU MAY HAVE BEEN AFFECTED
this setup has all the toys needed to work some serious small electronics mojo - the heart of it all the a 12volt power supply I got off ebay for $9 and the solderless breadboard you see with all the LEDs in it
100 bucks if you can tell me what the purple things with all the holes in them are (next the power supply) - they are going to hold new projects like LED blue ovals and the sound level meters
THE MADNESS CONTINUES
125 3,000mcd blue LED's and 50 chrome holders. total cost - $40 Ebay
What you are about to see is only a taste of what is to come... these things are so cheap and the possibilities are endless!
194 LED Speedo
194 LEDs on Ebay
pop it, pull it, stick it!
both sides missing! no socket on the back to recieve a bulb either - cant pull the speedo out enough to get back there... f#ck! Its just bright enough... wish I could put those 2 more in!
28 LED's total:
I couldn't have asked for a better result - its like a total blanket of blue light
these are wired into a sound response module with the neon so they will beat to the music (see next page)
I guess there's a bit of UV in that spectrum
Here is a behind the scenes view if you are interested in the wiring:
groups of 4 in series - all groups sharing power and ground in parallel
I was in the back seat one night absorbing the persepective and the idea came to me...
This one was a quickie - less than 12 hours from conception to completed project, including long breaks
And of course, like all these projects, there's not a wire to be seen
to keep it local I wired this by tapping into the power seat lead and hooked them up to this switch here in the fabulous walmart console
the Radio Shack LED holders I had been using fit perfectly into the Sunpro gauge bulb sockets. I mean PERFECTLY. It was almost scary... like they are meant to go together. By this point I also started using shrink tubing, resulting in a much nicer product.
these pics are pretty self explanitory!
the TACH: this turned out to be way too easy - a little monkeying around and the LED leads fit right into the socket. Dont forget an in-line resistor!
In the newer pics they all have 6000mcd LEDs from Ebay... at times they could be hard to see, so I may re-do them yet again with 10Kmcd LED's.
*This modification works better with the electrical gauges due to the smaller readable face area.*
194 LED bulb upgrade:
I was thinking about trying to make my own 194 bulb replacements, but they are only 3 bucks off Ebay so I decided to just get some of those...
the lens is diffused so the light is cast from the sides more like a normal bulb - this works better if you are trying to flood a small space with light since normal LED's are very directional.
Putting them in the vents is easy -
grab some 194 sockets from your local junkyard, paint them black, and stick em in!
I Theese do a pretty good job of lighting up the car by themselves! They are wires into the courtesty lights so they come on when you open the doors
I also put one here in the glove box and you bet your @ss I would have put one in the ashtry light, but I dont have one anymore.
I also found out even if you have a digital clock, there is a 194 socket (for the analog clock) back there so I stuck one there too. So now, behind the blue backlit faced tach, all the dash guts you can see behind the tach are lit up blue.
I cant stress enough how good these look. Colored 194 glass bulbs are a JOKE! they fade! This is where its at.
these are 300mcd LED's I used before I found the brighter for so cheap. These are actully a deeper shade of blue than the others
its FREAKY like a spaceship coming down at you or something... it casts a real ambient glow - see if you can make these out
here they are making a cool effect in some smoke :P
These also cast a decent amount of light onto the back seat, but I cant capture it in a pic
These serve as indicators for the ignition, radio, and headlights. (also 300mcd)
One rainy night I noticed how raindrops on the back glass reflected the blue light and looked like they were glowing. You have to use you imagination a little thanks to the poor resolution of this camera but you get the idea.

Bulk LED's run 10-25 bucks for 100 pcs of any color, even ultra-violet
here is alink to buy LED's on Ebay
Some options from Radio Shack:
LED holders 75cent
Resistors 10/$2 or 100 assorted/$5
Soldering Gun 10 bones
Helping hands (get em) 15 bones
Blue 3.7 volt 20mA 2600mcd (super bright) $3.99
Blue 5 volt 30mA 300mcd (bright) $2.99
Red 1.7 volt 20mA 800mcd (bright) $1.99
Green 1.9 volt 20mA 600mcd (bright)$1.99
Red 2.6 volt 28mA 10mcd ("old style" LED, meant to be seen and not cast light, common for security systems or VU meters) $0.75
Green 2.6 volt 26mcd 10mcd $0.75
so as you can see each wiring situation is unique
a car electrical system operates at 12 volts not running and up to 14.5 volts while running.
*** if you are not fammilliar with volts, current, amps, Ohm's law, resistance, resistors, soldering, metric units, or any of the following, Id suggest visiting the above link or finding a book on simple electronics before attempting to do this, as you are liable to catch something on fire.
rule of thumb:
(15 max volts - Led operating voltage)/ LED current draw = minimum resistance of usable resisitor.
My favorite is the blue 5 volt 30mA 300mcd
15v - 5v = 10v/0.03amps = 333ohms
need a 350 or so ohm resistor or two that add up to 350. Solder these to the leads with some small gauge wire, and enjoy! (Remeber your and - ends).
make sure things are properly insulated, and keep in mind that solder doesnt like to bend...
*** this info I give from my personal experience and garentee nothing as I am no LED wiring expert, but I know what worked for me
The sum of the voltages of what you have in series needs to be close to and not under the cars charging voltage.
Lucky me, three of my favorite LED's make 5 5 5 = our magic number 15, so it works great. .
Now, it has been my experience when playing with LEDs in series that things get strange:
four 2v LEDS in series will light up with 9 volts.
five 2v LEDS in series will light up with 9 volts.
six 2v LEDS in series will NOT light up with 9 volts.
evidentlty there is a gap and a cutoff point for volts when wiring in series... and since a car's voltage changes, this makes it hard to land in that gap.
My three 5 volt LEDs make a large gap (5 volts) that graciously accomodates the range (12-15 volts) so mine work.
It should work with many low voltage LEDs... but it may behave funny
