You can find the most common cells here. https://lygte-info.dk/info/indexBatteriesAndChargers UK.html Its a Danish site but all test for the last decade are in English. You choose the battery segment on top, and then you can go to a given review of that cell or use the comparator to stack...

They clearly want you to build something with that front-selection...[angry baby, baseball bats, knives, alarm whistles, and high-powered lasers] Please do so.. build it..!

Looks like standard off-the-shelf 300 series cheap Chinese laser pointers, just rebranded with a Sanwu label. If you get them from Amazon, AliExpr. eBay, or Sanwu. I doubt the inner hardware differs, only the amount of mock-up, but I haven't been there for many years, so I don't know if its...

That is the exact same question my girl asked and I had no idea as I was so gobsmacked / puzzled to see that single chinese AA-battery in the package looking back at me, that I didn't want anything to do with it. I have checked the battery... yes 1.56V ;) (Winner winner chicken dinner...

Our NUMB12 parcel from OpticsLD arrived today purchased at the start of February on Aliexpress.. "NICHIA NUMB12 465nm 8.3W 525nm 4.8W 643nm 10W" that to my surprise was shipped. But it looks weird..I haven't seen a NUMB12 in person, but I got a bad vibe that this ain't it. Looks a lot like a...

It's around the price I also got from sources in China. 250 to 400USD I purchased one in early February, though not from eBay but from one of the links I quoted in #5255 where the prices were even lower that those early eBay prices, though same seller And I didn't cancel it, even though it...

The main top-video (at Sun.co.uk) seems to be a mix of two different situations, as midway through the video, they have inserted old footage from protesters in Chile where an unmanned police drone was targeted and brought down, and Sun now tries to push this 5-year-old footage as it's the plane...

Though, this UK 99p seller did come true, so he do honor eBay listings that goes way under MSRP. (1/3) It arrived today from England (looks brand-new, as it should). https://www.ebay.com/itm/176256838856 Sofar only tested with a 488nm handheld stubby 1x18350 from around 2017 ...

Arrived today, so this UK seller seems solid. Were unsure if her would honor the auction price One thing is to purchase these RGB diodes from OpticsLD on Ali, its another matter to actually get him to ship your order.. Still have an order since start of feb at that specific seller (NUMB12) Its...

Wicked experience, but also on the verge that you could be hanging & dangling with so much patience if it is a purchase back from around September, but it likely varies from region to region, and payment method, and what amount of safety-net you have.. Have you checked the accuracy of these BT...

You can wick a compound with copper metal powder. that will set and do somewhat okay with heat transfer (all things considered) - if you absolutely have to meet certain size-offset tolerances but it will be a messy job to align etc. - but it sounds like it's just a standard off-the-shelf 9mm...

50 bucks.. that's quite a bit lower than the inner market value for these +20W self-contained mashup LPMs on Chinese marketplaces like Taobao & Alibaba/Aliexpress & eBay where they are usually around the 150 to 200 mark, though USD. https://www.ebay.com/itm/176256838856

Roger that.. I get no results on eBay, but there are a few listings on Aliexpress, Alibaba, Taobao etc.. Also from the same vendor, as the one that cancelled your eBay purchase. though to a way higher price now, and why I speculate, the reason for your cancelling of your order, was more likely...

Did you find another source around the same price? Does anybody have an RGB NUMB12 in transit atm? (shipped) if so from where /link? When I looked into these arrays before the Lunar New Year, the prices were quite a bit higher, than the listed 114USD on eBay.. all the other sources I could find...

sure, you can get green above 1W..but you will lose some in the beam-combining optics. The channels I talked with in China refer to them (green) as 1.65W x2 but these dual diode handhelds are still pretty new. The feedback I got from a week or two ago. Many sellers circumvent the wording of...

Many of the sellers on Aliexpress are just customers in somebodies else shop, often flipping / dropshipping items, and can at times explain why they are quite clueless about what is actually happening. but it obviously varies from product segment to segment. My biggest problem with Aliexpress is...

Will test with numerous well-known diodes and different wavelengths and try to have the voltage and ampere present while doing it, as that will give a good indication if they perform somewhat loyal and in the ballpark where one would expect, - at the end of the day, I did not pay a lot, ao my...

LPM Test with some old labby's from China 2015/2016 - 55USD# incl delivery to Denmark from the Chinese wholesaler Banggood (# on sale). They were both labeled & sold as 2500mW units and it was the same listing i got both from, though with 4 months difference in purchases. Looks identical from...

Purchased these two budget LPMs in early 2018' and now had them for more than 3 years, and thought I would share how they stack up and show the damage to the sensor area, after numerous years of use' - as I did also took some pictures while they were quite new and been lazing them with all the...

Sorry to rewake this old fellow of an LPM review, but sadly not much "review" as the title claims over the above post.. more like "see here is a picture of a Chinese LPM, and I'm not turning it on and won't share any info on how it performs" So I will try to dig a little deeper and hopefully...
