Ever seen one of these?


Well I had one laying around... SO I decided to have fun with it, and build something snazzy for my PC. All to be mounted on a 5.25in drive bay cover /biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' /> /biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' />.

This is the idea I had.
(<- switch in this corner)
5 LEDS in a line, with a normally open push button switch (to cycles through the led flashing sequences).

The flasher has 6 different flashing sequences, as follows.
(1 represents on, 0 off)
#1.) 1 1 1 1 1 (all leds on)
#2.) 1 1 1 1 1 (leds strobe at a moderate speed)
#3.) 1 1 1 1 1 (leds strobe at a slow rate)
#4.) 0 0 1 0 0 -> 0 1 0 1 0 -> 1 0 0 0 1 -> repeat (at a moderate rate)
#5.) 1 0 0 0 1 -> 0 1 0 1 0 -> 0 0 1 0 0 -> repeat (basically inverse of #4, same speed)
#6.) 0 0 1 0 0 -> 0 1 0 1 0 -> 1 0 0 0 1 -> repeat (same as 4 but very fast)

I chose to use the following led combination (left to right) White Orange White Orange White. Since I like these colours /smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' />.

I desoldered the old leds and soldered in wires so I can power the new ones. Then I measured and marked the holes to be drilled in a 5.25in drive bay on the front of my PC.Drilled the holes and put the LEDs in and hot glued them in (yes hot glue is an awesome modders tool /smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' />. I drilled a hole for the NOPBS (normally open push button switch) and began a 30min journey with jewlers files to make the hole for the switch fit perfrectly. After that was done I soldered and heat shrunk the solder points for the LEDs and the switch. All is basically said and done... except one thing....POWER

The LEDs need ~3.0 volts (a 3.3V line on a PSU will work perfect), but the only problem is, how to get that power. I think there is a 3.3V line for SATA (Orange colour) but I don't have a female end connector for it. Maybe a resistor? HELP!

The thing is build, I just need power for it. I should have PICs on monday at about 2-3PM, so check back then.


Edit//
I could use the 5V line from the PSU, but the resistor value I should use is somewhat sketchy.
The circuit uses about 200-300mA and at 5V thats R = V/I therefore R = 5/.200 or 5=.300 which yeilds about 25 ohms / 17ohms.

A confirmation would be nice. (5 leds, mfg. specified current draw unknown)

You forgot to subtract the voltage difference between the required voltage of 3 volts and the power supply voltage of 5 volts. So here is the correction: 5V-3V = 2V/0.3amps = 6.667 ohms. The resistor value is not critical for this application so it can be anywhere from 5 ohms ~ 10 ohms. The power rating of the resistor is 2v*0.3 amps = 600mW. I would use a about 1 watt resistor or higher.

Heres all the stuff I used to make this.


Holes laid out, perfectly center.


LEDs in, switch mounted. Ready to go.


Back side of the circuit.


Front shot of case, with circuit mounted.


Angled shot of above.


Lights off, light sequence #1 (as explained above).


I have a movie of all the sequences and right now im looking for a file convertor, and a place to host it. If anyone knows of a hosting place for movies. (It's ~8MB)

i really really like the slow moving inward led's!!!

when you turn them on high peed it would be good for a party!

you did a great job, looks very professional!

Thanks,

The wiring from the back does look bad, but you can't see it much if at all. If I did a plexi case I don't think I'd make it through it. I can't really stand seeing that many wires.

yeah it's prety cool but i would of ripped it out lol it would annoy me so bad lol /tongue.gif' border='0' style='vertical-align:middle' alt='tongue.gif' /> but i like the ideal /wink.gif' border='0' style='vertical-align:middle' alt='wink.gif' /> i would multipie the light by adding more and to be lowering the voltage on each of them and put them all over the pc /biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' /> i would of put them all white and make a stob light show inside of the pc /laugh.gif' border='0' style='vertical-align:middle' alt='laugh.gif' /> well i have a question and im serious about it ... i have a strob light and would like to put it into the pc case but it the voltage dangerous for the pc part ? maybe it will cause the pc to crash ? cuz it eats up alot of voltage maybe 50,000v in one shot


let me know guys /smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' />

Just make an LED strobelight, they're not that hard. Order a couple of white THC3 led's from www.lsdiodes.com I got some and theyre super bright even on only two AA batteries.

nah i was thinking is 50,000v in one shot to strong and may cose a radiation or something like it ... basacly can i run a light that strong next to my mobo ? and other electronic stuff ????

thanks /wink.gif' border='0' style='vertical-align:middle' alt='wink.gif' />

I don't know whether or not it would effect it, but for safety and size I would definitely recommend using the leds. The total cost would probably be around $20 for the whole circuit and parts.

Perfect! That was the exact kind of online store I was just looking for to source some parts for my voltmods /biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' />

Dude that looks awesome!

I am with Landlord, the slow mo one going in looks the best. How does it look with the door closed?
