I only now saw your email, Jay (just started with the cleanup - barelly got my main real-work customer off my back after two weeks of desparatelly trying to get some time off work)... I must say, i like the looks of the new CR2 heatsink! :D The bottom walls look pretty massive now! That's...

Re: 8x Drive Mini "GB" - DONE I just sent everyone your individual diode plots to your emails in the "Order Summary" row. Those of you who have already decided on the current/power they want (pick it from your plots), please let me know so i can complete your builds. A few want to wait for...

Yep, i'm assembling the second sensor/counter setup, but for the 12x experiment.. The parts required are a counter and a GIANT heatsink. That, and a new sensor (which can easily be made out of parts i have on hand). I bought a second counter a while ago (after learning i'm torturing a 12x), now...

The diode reached 123h+ over the weekend, uploading the latest degradation plots.. 123h P/I Plot: 123h Efficiency Plot: The graphs now only show the plots that are evenly spread appart in time... Diode Stats: Ith = 36mA (no change here) Po @ 300mA = 317mW (89.04% of initial) Slope...

Re: 12x Murder Fund! (Complete!) I am happy to report, that today i received a "Replacement for defective photodiode (in mount) - $2 USD".. :crackup: Looks like Dave has our customs figured out by now.... :evil: Now i just need the Modwerx heatsink, and i can start the 12x Murder experiment...

Actually, it wasn't in the preview (and dissapearing upon posting), it was posted, it was definitelly up there, same way it is now. But then i reloaded the page to check for new posts and it was gone... Only thing i may have done wrong was that i forgot to close the Attachment Manager window...

Which 500mW rated diodes? CW or Pulsed rating? I haven't heard anything of that type, altho i haven't had much time to read the forum latelly, so i might have missed something. :thinking:

Ok, what the heck?!? I DID attach them! The texts were referring to the pics embedded into the post... And i just saw them, then i hit RELOAD, and i see your post, look back up and they dissapeared?!? How is this possible? :thinking: I'll fix it immediatelly. P.S. The diode is pushing on to...

Fascinating... When it deviated from your projection, it later got back in line.. There was a time when degradation seemed to speed up, but now it's as if it's slowing down again... Except for that one point, it follows the projection almost perfectly! Some deviations from a calculated...

The diode succesfully reached 100 hours ON-Time two days ago. Still alive and kicking! :yh: This was a very special moment worthy of another photo: It was only 10h since the previous tests, but since i had a feeling degradation was speeding up i was more careful, and wanted to replot more...

Slipstream & Pyrotech: Please contact me via Skype OR write me an email with the SUBJECT "LPF RAFFLE", so i can answer you faster and sort out your lasers. :yh: Thanks!

Oh man, i forgot i didn't send it yet. :yabbem: I had a crazy week at work yes, today is the first day i have some free time. I'll send you the invoice now. EDIT: Sent. Thank you for your work, Jay!

Luckily the apparent high forward voltage came from an error in my measuring setup. As i have shown with the first two 12x's, their Vf's are LOWER than with 8x's at the same currents, NOT higher! The reason it came to this error is the way i tested the diode. I only have two wires coming out...

Indeed, it's a proper freak, even for a 12x (altho we might see even more surprises as we test more of them). Attached is a comparison plot of the first three 12x's... But believe it or not, there was one 8x in the batch that actually did 460mW at 300mA as well! And at 360mA it would have...

I wanted to do an efficiency comparison plot earlier as well, to see those strange "humps" 12x's form (or so i thought), but i was low on time. I also thought it was pointless since the P/I plot was straight. But i need a break from work now and then, so here goes... Observe what a peculiar...

I just plotted the Plextor 12x diode in high resolution, and i am more than a little surprised by the results! I expected two things: (from Dave's previous experiments) 1. Lower Vf than with 8x's 2. Strange bends in the PI line But instead i got the exact opposite! :thinking: Here is the...

I arranged it so, that i will finally have some time as of Tuesday... Had to stay up most of last week and go do a big installation at my main real work customer over the weekend, as well as move some deadlines around a "little", but... ...this means that i can now prepare the drivers for the...

I just received the Plextor PX-B940SA 12x Sled from bug373. Wanted to take many pictures of it's dissection and so on, thought it deserved it's own thread like the Pioneer, but then i got this funny familiar feeling when i ripped off the 405nm diode's heatsink. The feeling got even weirder...

Sorry couldn't post these sooner guys, it's been a busy week at work. 90h Degradation Plots: Diode Stats: - Ith = 37mA - Po @ 300mA = 325.5mW (91.43% of initial power) - Slope Efficiency = 1.233mW/mA (Avg.) - Actual Efficiency = 18.42% Peak / 18.17% Avg. I've noticed something...

Re: 12x Murder Fund! (Complete!) Wasntme... :angel: I don't know how much it cost, but i think it's good to test as many different ones as we can find (and afford)...
