So, I read this thread and nobody mentioned using an alloy to drop the melting point of the solder. Am I missing a reason this won't work? You can set the block on a hot plate at just 100C apply a little BGA flux and melt an alloy of of bismuth, tin and indium (like ChipQuik) at the back of the...

Well, of course the facts aren't straight, that's the nature of viral tech videos. This unit is roughly equivalent to all the other ones I've seen on this forum, except flashier and targeted to set off inexperienced YouTubers. Plus the fools who browse websites like hackaday. Think about KipKay...

The right side connection in that picture must be different or broken, I have seen diodes where both pins have a lead that comes off and contacts the die, you can power it through either pin. I haven't checked to see if powering it using both increases the max current or anything. EDIT: I'll...

An image I found on google, shows the two pins capable of energizing the crystal gain medium thing. Another image says to power the diode through only one pin. SO.... does anyone power their LPC-815 using both pins? Would it improve the diodes performance or anything? It looks to me as...

I really have no idea what's going on in this thing, but it looks like the little rectangular crystal is being pumped by the two little electrodes on either side... I notice that as long as the case pin is negative I can connect either of the positive pins and it'll lase. But why don't I...

Oh well I know it's horrible, I wrote that at 1:30am after being awake for about 36 hours, I don't want to mess with it anymore, I've got people bidding... I plan to sell more, next time I'll completely re-do the listing. I'll do it again sometime when my brain is functioning properly. My...

Looks a little better now.

Of course, thanks. I was a little tired and forgot about the nature of what I was writing, it reads like a casual email. I might tick someone off by talking down about the Korean sellers too, I'll edit it. Thanks for pointing that out.

I thought I'd try and sell stuff, EBay gave me a hard time at first, but everything seems calm now... I just got the traditional bot email and then changed a few things before re-listing. 405nm blu-ray SHOW/DISCO/"RAVE" laser module HIGH POWER - eBay (item 170485232742 end time May-15-10...

Just curious, what's this new business?

I didn't really expect to transplant my first diode successfully, however I just made a second attempt and it worked. I'll admit to a steep learning curve, these diodes are a lot more sensitive than what I'm used to. And earlier, I was actually trying to be funny (not offensive), maybe I...

Why are you guys out to get me? What do you think I ever did to you? It's not like I'm the guy who was on here earlier asking for tips on frying people's skin and vaporizing animals. You sure seemed eager to help him out! LOL! Even I wouldn't support that! However I may have wounded a poor...

Wait... I didn't mean to offend anyone... Is anyone offended? I'm sorry if you're offended, that it was not my intention. The only thing that should make you guys rally up as you did is if I posted something like this: LiveLeak.com - Puppy Thrown - Iraq And said HEY guess what I did last...

What? That stuff doesn't hurt anybody does it? :) Well, most of the time it doesn't... :D

If you think missile launching RC aircraft is dangerous, check out spudfiles.com, it will set all your illogical safety/legality concerns straight.

Hey, I fixed that RKCSTR driver that was outputting 980ma, the solder on those two shunt caps that are close together had bridged, I just resoldered it, and it works fine. And that battery I use has a nominal voltage of 11.1v it was at 12.5 when I first charged it and hooked it up, now it has...

I didn't run that diode for an hour straight, maybe 25 minutes, over the course of an hour, I never noticed any heat in the module or anything... I pulled the LCC 16x red diode out of the sled my GGW-H20L came in and it's working great. I notice, It seems harder to look at a 650nm dot than a...

I was thinking about getting a BDR-S03 diode sled, they are supposed to be 8x and are usually under $50.00. But someone said that the 6x GGW H20L actually outperforms them. Maybe I'll try other wavelengths and get some practice handling cheaper diodes. Then I might attempt something with a...

When I first started building nitro RC stuff, I blew up a few engines before I figured out what I was doing. I guess it's like anything else, it takes practice. I was a tiny bit too rough on my diode, I took a tiny bit too long when soldering... Maybe 12.5v was too much for the RKCSTR, it...

On the first day! I was running the RKCSTR driver on a 12.5v 3s Li-Po battery, and the GGW-H20L diode was running at 203ma. I was trying to laser my signature on a bench for about an hour while waiting for the bus, It only got very slightly warm, I was running a pair of 12mm motor heatsinks...
