Woulda bought it myself but only ships to US!!
9V or PSU still the same behavior. I have been pushing this diode a little now and it has turned into a freak ;) ;) I pushed it to 95mA - it worked and is still working. At that power I could see the beam in the dark with no fog or anything. I am now running it with LM317 + 22ohm = 56mA's and it...
I guarantee you it is still lasing...but the lasing threshold has been raised. Like i said it's strange but I guess i'll have to see how long it lasts. I've been running it at 55mA now for two days and it seems fine.
Something funny has happened to my second diode. It was working normally using a bench supply and LM317 circuit and lasing at about 28-30mA - i was driving it at 40mA with short duty cycles.
I then connected it to a 9V plus LM317 circuit and now it only lases above 38mA and the dot can not be...
I just had the same scare with my second diode. But with a bench supply it's ok.
:o :o :o I just saw some awesome effects with this thing...try this guys - take the collimating lens off and shine the light at your teeth and check it out in the mirror. Then shine it towards but not directly in...
:( :( I fried my first BR diode... I was testing it on a breadboard with the LM317 circuit @ 12V input when the Vin wire came loose and touched the flat pad on the IC for just a split second and then.. poof!! It stopped lasing.
When I tried it again there was no more light output at all...
I finally made my BR laser :) :) It's freakin trippy :o . My eyes almost feel like they are crosseyed when i look at the dot on a white wall. And you guys are right - it can be focused to a pinpoint.
It's hard to explain but the colour and the focused dot plays tricks on my eyes. It's soooo...
:) :) I finally finished making one of these and works pretty well. It burns un-sharpied red matches, pops balloons, engraves black plastic, etc. I used a smaller surface mount TI LM317 TO-252 package (which is good to 500mA).
I used a 5 ohm resistor (10ohm || 10ohm) which should give me 250mA...
:) :) I finally received my DX 30mW Greenie and boy was I suprised. I only had a few minutes to play with it before work today but so far I'm quite impressed. It's very bright only running off the included batteries and fairly well collimated. The beam is very visible in mid-lit conditions.
All...
Since I ordered the elly I've found some threads on CPF:

The ones we can buy now have a crappy cheaper boost...
I just received three flashlights from DX which I plan to convert to lasers as soon as i get the GB red LD's.

Stop talkin about it guys :-?I'm gettin jealous here as I have yet to receive my units here in Aus. :)
I am still waiting on the red GB too...I now have everything ready to make like 10 lasers (Blu Ray and Burning) - except for the diodes ;D
