If you did not receive what you ordered, it's a fairly straightforward PayPal dispute to get your money back

If you go with the build I recommend you you can add a graphics card depending on budget The cheapest I would go with is a 5600XT or RTX 2060 which are around $300. Best bang for your buck is a 1660ti though which is around $250

Do you have a graphics card? If so and your cpu has integrated graphics try removing the graphics card and plugging the monitor directly into the motherboard. If not you should probably look into a new computer because either your cpu, or motherboard is bad. Or it could also be a bad PSU...

This is Jake This is Tiger (pronounced Tiggur) This is Simba. Simba and Tiger eat the same food and are the same age so I don't understand why Simba is so fat.

LPS.org? Lincoln Public Schools? What?

Sounds like a power supply problem or something came unplugged. Check inside make sure everything is connected tightly, reseat your ram. Make sure the cpu fan is plugged in. If that doesn't work you can try using a multimeter and checking the voltages coming out of your power supply.

These are 532nm, but green is green, dpss has better divergence anyway https://www.optotronics.com/green-laser-pointers.php

I don't with mine mainly for the safety concerns if the laser turns on randomly. But if it's a lower powered laser I trust I leave the batteries in.

Could just make them pay as gift. PayPal won't do anything if someone pays as gift.

You are wrong, while mw is not correct it is understood to be mW. However microwatt is µW not mw. The cheapest LPM that is legit is the hyperion, however they are hard to get ahold of these days. Another option is a used LPM from a member here but those are rare and far in between. Another...

I have a 1W 445nm laserbtb laser. Pm me if your interested

My understanding is the sale of any handheld laser in the US over 5mW is not allowed. However, unless it's a large operation like wicked lasers, no one really cares.

You can make anything cheap if you make a lot of them and source all the parts as cheaply as possible. They probably are able to get the diode for $15 or maybe even a lot less. The rest they can make super cheap. Just some aluminum and possibly even acrylic lens.

I'm in eastern north Carolina, I have 3 LPM's. Where are you located? :)

They shipped my order a couple days ago so it should be here in a week or two. Will post updates when it arrives. I got in contact with someone at the company to ask them when my order was shipped and they responded within a day or two. If it turns out to be a 1W Blue I will ask them why they...

Assuming they are using the NDG7475 for the 520nm, it is capable of higher powers and also more expensive. I believe the divergence is the same. Whether or not sanwu drives them to the higher powers I don't know. But if they don't then it should last longer so either way win win. The price...

Cameras percieve colors a lot different than the human eye, a good example of this is 445nm which to us looks indigo but on a camera looks purplish usually. Also on their website they may have been showing the 150mW version of the 520nm. Brightness to the human eye depends on if it's in a...

The danger is determined by the power, not the color (until you get into the IR range) . Any 1W+ laser is extremely dangerous. Green is the brightest. If you want a safe bright laser a 5mW 532nm is the only option. If you are pointing it miles away and concerned for people in the mountains...
