Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I'd like those lens housings more if they were a bit longer. They are just 8 mm long, but the housings need to be 11 mm. I have several aspheric lenses that could be used in a housing, but only if it is 3 mm longer. Some of my lenses have a greater FL than the ones that come with the NDB7875.

Here is an interesting yellow I found on Alibaba: https://www.aliexpress.com/item/Good-price-PGL-III-C-589-5-80mW-589nm-Yellow-Portable-Laser/32839206414.html?spm=2114.10010108.1000014.15.3d2d9950rDu9HZ&traffic_analysisId=recommend_3035_null_null_null&scm=1007.13338.80878.000000000000000&pvid=a4c2417f-94cc-4a9a-aa63-a77149e68aa3&tpp=1

Probably the cheapest 589nm I seen so far, yes the shipping is another $100, but it still comes out cheaper than other yellow lasers. Not sure on the credibility, and the 5mw-80mw power specification is not very specifying. :cool:

And also this:

What kind of red color is that for $118? I messaged the seller about it, waiting for a response...

That second one isn't a red. It is another 589nm pointer in a different host. I think there is something missing in the translation. I have my doubts about these lasers too.

The pen 589nm has two good ratings but yeah I don't trust those either, would be nice to see more feedback from people who bought them.

Damn. You are at SeaTac. That is only 30 miles from me. I'd have gone there to see you had I known, Chris. Will you be home today?
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I'm at a bar downtown right now, need to be back at Seatac by 7:30
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

My daughter is coming by in an hour. It would be a rush to try to get to you before you board your plane. Next time, let me know ahead of time. I would have loved to meet you in person.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

OK, will do, this whole thing quitting my job and all has been uber compressed for me.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Sounds like it all happened very quickly. Glad you had another lined up first. How much time before you have to leave for Qatar?
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

i hope 2 weeks, i better get outta this section, everyone seeing activity are gonna come looking for a deal.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

So this may not be a super deal, but I'll throw it out there anyway.

Looks like a 3W 532nm laser head. To make it work one would need to build something to run the diode, TEC, ktp heater etc. So not necessarily easy... but not too hard either. With the make an offer option it could be a reasonable deal, I don't know:thinking:

I bought one of those from another seller a couple of years ago or more, they put out a very nice little beam. I had set up three adjustable power supplies to do it, monitoring two thermistors with a DVM to adjust the power to the diode and crystal to keep them at the right temperature. It was a big challenge to do so by hand, having to continually jump from adjusting one power supply to the other to keep everything at the right temperatures, but it worked until i became tired of the one armed paper hanger act.
