Mine has a max temp of 500c and takes approx 4-7mins of heating evenly with the largest tip and airflow set to its highest. By the time the diodes break loose, both the block and the diodes are at the melting temp of the indium. This is why I like the idea of rapidly heating the block, it's...

Agreed. I have an 852D workstation and it's a great tool for pretty much 99.9% of the work I do. Bought it to reflow PS3 graphics chips, and then used it on these diode blocks to extract. My point was that it may be more stress to the diodes using this tool given the mass and surface area of...

I think an argument could be made in favor of using a a torch in this situation. It looks like the diodes are exposed to less heat for a far shorter duration of time. When we solder diode pins the goal has always been to keep the heating time as short as possible. From what alien posted...

Was looking over the test data, is there any wavelength shift in the NUBM47-A1's by any chance? I cant find much info on these ones.

Sounds like the torch may be a safer method. Been a while since I extracted one of these blocks, but I remember it taking 5mins or more and everything including the diodes were hot 🥵 I saw no degradation running my heat gun at its max of 500c, and will definitely be trying a small torch next...

I wonder what is better for the diodes, the longer process and prolonged exposure of a heat gun or the rapid heating and shorter duration of a torch 🤔

I used my smd hot air gun and sat the array on wood blocks rather than clamping it in a vice or anything thermally conductive. Even tested the raw output of each diode before and then after extraction to see if I had damaged any. Really had my nerves shot for the first one, but all was good.

That's not bad. I was hoping it wasn't too low like in the 30's or the like. Don't think I've ever let a handheld go anywhere near 50, so definitely worrh checking out. 🍺

Forgot to ask, did you happen to notice what approx temperature is the point where the wavelength begins to drop back down whilst being over driven? Also, how much can these diodes take before they fail? I used to run my a140 builds at 1.2 - 1.4a iirc. Don't think I ever got close to 2A let...

Jumping spiders are quite unique having a strange awareness to their surroundings. If you get their attention simply by standing in front of one, you'll notice they give you undivided attention and will follow your motion closely. Never liked spiders, but the jumpers are fascinating. I don't...

Sweet color. 460 - 490 is the hypnotic part of the spectrum for me 😋

That's crazy! 😮 Been playing with the NUB series for a couple of years and noticed with the 08's that when pushed the blue became lighter, but never realized there were so many others that had such a dramatic shift. I really should have invested in a spectrometer. Thanks for the insight and...

Appreciate the info, thanks 🍺 Our of curiosity, are there any other common blue diodes known to swing this high when overdriven?

Found this listing which says it's a block for the 141 but looks to be the same as the 140. The marking of LSD 25 is the same as the 140s that I pulled years ago, unless the listing is wrong or some had the 462 and some didn't...

According to the list of diodes a few posts back one of them is an LG projector, but his video says m140 vs m140 C. I'm assuming the 'C' is an m140 variant? My block has no markings other than M1 written in marker. Guess I'll just have to test it and C 😁

I have a block of 24 diodes from an m140 projector, I have not tested any yet. I am wondering if there are any markings or numbers to look for to see if these are the higher wavelength diodes?

Took it about 30 seconds for this one write me a song about the large hadron collider Sure! Here's a song about the Large Hadron Collider: Verse 1: There's a machine so massive, it spans the Swiss-French border It's called the Large Hadron Collider, and it's like no other It's a particle...

Now this is freaky. I posed the same question as last night regarding my headlights burning holes in other cars. Again, this system only has access to its existing database. First is the question from last night, then below it from today: Last night me: why do my headlights burn holes in other...

Its getting into scary the way the answers are given. Im not sure in passing and a quick chat that I would be able to tell the difference between it and human. It even will write you poetry. me: tell me a poem about lasers ai: Lasers, beams of pure energy Shooting through the air with such...

Playing around with ai chat, and am quite surprised by a database that has no internet search capability. Its worth a try for serious and stupid questions. Heres the link and a few of questions I posed to it. https://openai.com/blog/chatgpt/ you have to register* me: why do my headlights...
