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

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

Are you going to buy it? I don't need it as I am covered there. Also, some of these diodes have a Vf higher than 7 volts at a high enough current.
 





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

I just bought a 0-60 VDC supply made by the same company which can do 18 amps and have one of these from another seller on the way. I'd go for this 7 VDC one (most go a bit higher, 7.5 VDC or more) but I have one already.

Yes, the vast majority of lab supplies will safely go 1-10% over their rated voltage. It is usually even part of the calibration procedure to set the max voltage there.

I wonder how you are in person

Would you really be offended if I said these things to you in person? Really? All I gave were facts. If facts upset you, that's not my problem. I'm quite agreeable in person and get along very well with my peers - no drama at all. Yet, I will never hesitate to tell someone they are wrong. I guess in my line of work and in my line of friends, that is appreciated and reciprocated, and I wouldn't have it any other way. Sorry it isn't the same for you.

Not your problem when you are too terse with people, true.... In time though (probably) you may come to understand how unnecessary it is enough to lighten up on that act, as well as it is more important to be kind, than just right alone. Be right and kind at the same time, the two can coexist together in one individual, if you have the patience for it. For the most part, over the last four years you seem to enjoy posting when you can take pot shots at folk, instead of sharing anything you are doing with lasers anymore, often the information warranted, that I do not dispute, just the way.

Edit: Here's a deal I bought a few days ago, no need to bring this link to the forum, zap, gone!

https://www.ebay.com/itm/Xantrex-LX...-Xantrex-LX-60-2-DC-Power-Supply/152914644037

These two combined with the 60 V 18 amp supply I ordered yesterday and I will be set up fairly well for a hobby bench, not what I have at home, but for where I'm working now will get me through. Here's a lower voltage high current model I just ordered: https://www.ebay.com/itm/XANTREX-60-18-DC-Power-Supply-0-60V-0-18A/302404043674 - One just popped up with a starting bid of $99.99, at that amount a steal, even with a high delivery charge: https://www.ebay.com/p/Xantrex-XHR-7-5-80-DC-Power-Supply-7-5v-80a/661405134

Here's another 18 amp unit which might be snagged for about the same: https://www.ebay.com/itm/XANTREX-60-18-DC-Power-Supply-0-60V-0-18A/382423324284 - Some HF noise, but suits my needs. Sure, it's a switching power supply, but the specs are good enough for me, I could, but I probably won't be powering diodes with this one having the Xantrex XHR 7.5-80 power supply I also just bought (10-turn voltage and current potentiometers).

Most of the diodes I work with don't need more than the 7.5 to 8 VDC that high current model can produce, unless I string them together. All together I bought four of these Xantrex units, I'm now power supply heavy here, but all switching supplies. I don't want to afford shipping on linear power supplies which are far heavier for the same current producing ability. I was also looking at the essentially the same units branded with the Sorenson name instead of a few of the more recent Xantrex supplies (see note below), they can often be had cheaper and would do well for me too, just that I found these other ones. According to the following, there's been a convoluted branding history:

Note: Snip, paste... The Sorensen brand, owned by Elgar Electronics Corporation (EEC), was acquired by Xantrex, Inc. along with EEC in 2006. The Xantrex programmable power business division was shortly acquired by AMETEK, Inc. on August 25th, 2008. The existing Xantrex product lines were then rebranded to the Sorensen brand name.

Specs for the Xantrex 60-18:



If anyone is using a switching power supply with too much HF noise, put a ferrite choke on the DC output wires attached to the unit, should help. I will be testing mine to see how well that will suppress the 0-20 MHz noise and report later, have worked for me in the past.

I don't usually see a connection with stating a fact, and evaluating kindness. If I say to someone "that device has 1-turn adjustment." is that kind, unkind, or entirely unrelated to kindness? I legitimately don't understand how you're offended by something so benign and inconsequential. It makes me wonder how you would deal with something actually severe.

How would you have said it differently?
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

I know your method of questioning my statement to WizardG that there were no other options available to me for lighting in an indoor grow was a bit harsh as I was actually referring to the lack of LEDs that could be programmed to shift wavelengths in a grow room back in 1982. If you had read all the comments leading up to that one comment of mine, it would have been obvious why I had said that. No one I consulted back in 1982 about indoor grow lights were talking about programming wavelengths of light to optimize output.

I'll pose the same question to you. How would you have said it differently?

I don't understand your question. Which post are you referring to when you ask me this? If it was mine about the lighting, I think I've already answered that. If it is about something else, I need to know which.

Root of the problem is something I can point to, but this thread isn't the place to do it, if at all, probably won't be accepted as valid.
 
Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please

Anyone know any good laser holsters out there? Would be nice to have holsters instead of putting lasers in pockets. :D
I found some flashlight holsters on ebay, not sure if they are good for lasers.

Those 532nm ones are especially high when you factor in his shipping price. That seems far too high for what it would take to get one to me.

Ouch, just noticed the shipping! If the seller knew what was wrong with them it might be worth it. If it's just the pump diodes or something simple like that they might be worth fixing. One of our EU based members may fancy taking a stab at it!

If anyone still wants Blue Phlatlights (maybe Red as well) and KE-arrays with 40 M140-type LDs check this guy selling 1650s in tens 100GBP each.

This is 2nd bunch I see he sells this month, with more of a prof. items I do not know what they are for (video scalers, 5000Lum Panasonic etc.). Maybe a disco selling off the used equipment...
I purchased one to try from last week's sale - it has 4500h of "lamp time" but still shows fine picture on the wall with no pixels burned out. DMD chip looks not damaged. Anyway, where does one get a new PJ for just 100 pounds...

Has 1 red and 1 blue PT121 LED. They are really nice.

Knife edge mirrors are glued to the main optics housing unlike the M and A series which had the small removable knife edge array. If you are after for just the bare mirrors they can be extracted individually but there is a testing thread over on PL that shows they are a little lower efficiency so the advantage to the knife edge arrays are the preconfigured mounting and if you are having to mount and glue them anyway might as well just pick up some good bounce mirrors.

For diodes it has mostly A-Type M140 I have a picture of the block showing the quantity and their placement. I posted it here in some somewhere. I think it was either 32 A's and 8 M M's or it is 28 A's and 12 m's. M's grouped in the center.

Interesting insight I was given about the actual reasons for all the different mixes other changes/tweaking they have done as time went on.

It has a lot of compromising in the A and M units due to using one monochromatic source that is responsible for producing two of the main color sources. Got to factor the conversion rate efficiency off the phopher to get the lumen output needed which based on the wavelength and total power and the wavelength that is directly passed for the blue to get the best color balance

From what I was told the optimal for conversion off the phopher for green is around 442nm.

They always had issues finding the right trade off to get the lumen numbers and a directly passed blue for color balance with available diodes and the design confinements of the A and M units. The blue pass was always the weak link which produced poor reviews for the color balance.

Poor reviews of the A130's dismal color balance might have been the nail in the coffin for the whole slim eco laser projector if they were not so invested and the fact they were marketed more for business uses not watching movies.

The H-series have advantage that the pump source for generating the green does not have to pass making the blue source. So the laser blocks only concern is to making the green. The unit was large enough to have a dedicated blue light source which had a much better wavelength.
