I have an old school Orion XTR900 car audio amplifier that I'm looking to repair. It died on me just recently and when I pulled it apart i discovered 3 burnt MOSFETs and a charred 1w ?ohm resistor. The MOSFETs are Fairchild Semiconductor part number NDP7060. I'm trying to track down a suitable...

I got my driver today(finally!). I already did some customized it a bit. I forgot to take a picture before I modded it, but here we go. Heres the front of the board. Shows the potentiometer in the top left corner and the switch was in the middle, but I already bypassed it, with a bit of a...

Alright. I've been closing every night at work, so I haven't had much time to do anything lately. But I'm off tomorrow so I figured I would get some pictures up. Module Diodes Powered it up with a usb cable and a 100ohm resistor. I still havent received my driver, But so far this laser...

Alrighy, I just recieved my module and diodes in the mail today. Ill have pictures up soon. The module is pretty decent

Im new to this whole battety world. So take it easy on the noob.

Alroght. I did a little looking around and im thinking maybe 2 6v batteries or 4 3v batteries. The 4 3vs would need a long case, but 2 6vs would probably be about the same length as a 3 AAA battery pack. I may consider 2 12v batteries (a23) and running a resistor or a small pot to drop it down...

...... A driver regulates current for longevity. It needs a battery to work? I didnt know that the driver pulls electticity out of nothing to power my leds.

The reason I wrote it out that way was because I was demonstrating to my roomate the difference in parallel and series. So, Series would be the best, which means 12-14V supply at 1000mA, or 12-14V 3w. What would be the best way to get 12-14V from small batteries? I want this flashlight to be...

Read through DealExtreme a bit. Couldnt find much info on how to run 4 CREE leds togetger. What would be the best way to wire these? In parallel or series? I know that the small 9 led flashlights are run in parallel. I dont know how to equate what kind of power I will need either. The leds are...

Take a vote?

So if I can get copper washers ftom a hardware store near by, it will work? Im trying to avoif spending mich more money before I get paid next week.

Thats one think I didnt think of yet. What exactly does a heat sink need to be? Like, if I had my friend that owns a machine shop make an aluminum plug that fits inside the housing and fits around the module, would that suffice? Would it need to be finned?if I get a couple of washers that fit...

After doing some researching and finding that CREE leds are EXTREMELY bright, I want to build a multiple CREE led flashlight. One of my current flashlights uses a CREE led and after searching the circuit board for quite some time, I have found 1 SMD resistor, and I can see 3 characters on the...

Any chance somebody here knows how to take this sucker apart? Ive tried unscrewing the lens end with no luck so far. I want to pull it apart and add an led from another 130lumen flashlight, in which I'm using the housing as my laser host. Also, anybody know how the leds are are attached to the...

Just ordered 3 pairs of the goggles from amazon. Theyll be here in 3-5 days and all the stuff for my laser will be here on the 24th to the 30th. Im going to be putting it inside of this flashlight What do you think of this as a housing?

Im looking for a fairly cheap pair of decent laser safe goggles/glasses. Would Something like these work alright? New 200-540nm Eye Protection Goggles Green Blue Laser Safety Glasses Free Ship | eBay

As stated, this is my first post here and I have just ordered the parts to build a BluRay laser pointer. Ill start with a parts list. Diodes. Figured I'd get the 2 pack in case I mess up the first time. PHR805T 120mW 405nm TO18 Laser Diode/Violet Laser Diode/2 Pcs | eBay PHR-805T diodes...
