I bought some of the UV LED's thats MustangP51 sells and made a small 10 LED array out of them.. Gotta order more now anyway I have not decide what to do with it yet lol I just built it to have something to do...



I cant get any good pics with it in action lol... oh well..

lets see the beotch lit up!

could not get any good pics of it lit up.. It was bright as hell in its view range... It was able to lite up a black light poster from about 10 foot...

Ohhhhhh....I would pay good money for one of those ready to go like that....

what color? lol

Heh, UV, but I am just about to do my mod this weekend, so gonna be out of money for a few days.

nice very nice, i need to build an array miself also

stupid todo list lol

That looks good, Twizted. You could make a couple of bucks selling those.

Think so? I could do better on my soldering.. Its just I was bored and sleepy and lol.. well.. you know... I am going to go to Ratshack later and get some Transistors and what not to make a HDD array also need more Project boards... Last night I made a battery powered (Push and Play) LED tester lol... nice compact lil unit.. houses 2 AA batteries and you just push an led into the plug I mounted in it and you are good to go... anyway I just go up and still kinda cloudy eyed so I am going to quit my ranting and motivate...

if you plan on makeing alot you could have single sided PCBs made. its actually not that much cost wise.

Could you maybe go into a detailed explanation on how you wired the leds together, and then to the molex? I know its a dumb question, but I am clueless when it comes to electricity.
Thanks

Actually that is a good suggestion there Casper, cause I'm sure there are people out there that are very interested in doing something like this as well, and would appreciate a mini guide of some sort

I will work on one soon with a diagram ... its very simple really... I would do it now but my Grandfather has passed and we are busy taking care of things.. I was just chking in.. I will talk to you all soon and will make up another array with a guide...

Twizted - sorry to hear about that bro

well thanks to certain rules, laws, and suggestions of electronics. this is what i came up with. for alot of reasons.
its suggested that you DO NOT drive two or more LEDs in parallel with a single current limiting resistor because the LED with the lowest forward voltage will pull the voltage down to that level.
if you run in series you add up all the forward voltages to get one big forward voltage. your power source must put out that voltage or more.
now you dont have to follow those things but you arent running the LEDs as brightly as possible.
so in my design it might use more parts but it is more technicaly sound.
so in my design if the LEDs are rated 3.7 volts and 20 milliamps (0.020 amps) the resistors should be 600 ohms if the power source is 12 volts.
there is also a reson for why the resistors are after the cathode.

but if you want to do it like twizted it looks like this is what he did. and his resistor looks like 29 ohms unless the first band is ornge and not red then its 39 ohms

Who makes the best array?

If you guys are willing, I will reveiw them against each other.

39 ohm resistor... And yes thats pretty much how I made it..
I was just tinkering... I would have done better but I had a limited supply source lol ... The resisitor came out of my box-o-sh*t (various bits I had taking out of old usless electronics) the jumpers were from the LED's as were the connection rails on the bottom of the PCB... The whole setup produced more heat due to my design (which was spur of the moment in my head thought up lol) I should have broke out the old PC Electronics workbench to test it.... I have took it apart and am going to use the LEDs for a HDD array as soon as I can get to the RatShack.... If I were to do that one over I would have used a series design with multiple resistors etc.... BTW would you explain teh reason for the resistors being on the cathode side?
Oh.. and btw the whole array was equally bright with no problems there just didnt like the design after I had looked at it and played with it a while... have a rather interesting HDD level indicator coming soon

Oh and BA... As far as best... I dont really think it would be a matter of best as much as the fact it works I mean best would depend on fundage and quality of parts available and as I am on the po end of the pimp'n game mine would look much like the above on a premade RatShack PCB but as long as it functions properly its all good

Ok, please forgive my ignorance, but I have no clue what that diagram means, could someone please break it down into layman terms for me? This is a mod I would really like to do, and all help is much appreciated.
