Hey guys. I asked if it was worth it to cell these on lpf a few months back. People said yes. So here they are. I have a few hundred. Not sure how old. They hold a charge and read good with a volt meter. Not sure what the price should be. How about 2.50 each. Minimum order of 4. Plus...

Hey guys. My friend came across 50+ laptops that he was scraping for the gold etc. I told him that I wanted some of the dvd drives and he asked me about the battery packs. We cracked a few open and they are stuffed full of Samsung icr 18650's. The laptops and battery packs worked before he got a...

I did a search for this subject and found mixed info on it. Some said yes some said no. Some said only flat tops would fit some said button tops would fit. I was surprised to only find one thread on lpf about it and it ended with no conclusion. I didnt want to buy some batteries online only to...

I built my first laser a few months ago and, just as I suspected would happen, I want to build another. Even though I have no idea what to do with one laser let alone two. I have burnt everything with in ten feet, cut a line into my laptop screen, burnt the couch, started a few fires and have an...

I bought some gtl 2300mah 16340 batteries a few months back in preparation for my first laser build. I didnt know anything about the batteries and figured I would give them a try. Well as some of you might know these batteries are pieces of shit. I think they actually hold about 150ma of power...

I searched the same question here and on google. Other people had asked the same question but the people that answered it didnt understand the question. They answered it with things like dust in the air reflecting the light. But that explains the beam, not the trails from the a moving laser. So...

So my 4 d cell mag lite that I have had for 20 years got stolen, Yes I am very sad. But because of that I was willing to buy a new one. I bought a 3 cell and I believe it specs out to be brighter than the old bulb style. I took it apart and was looking at the emitter, I believe that is what the...

I started a thread asking about how high visually one can one see a laser in the night sky and it made me think of something else. I was shining my laser straight up and my buddy who lives about 4 miles away could barely see it but only if he was not trying to focus on it. He had to look to the...

Hey guys. I just finished my first build and I have a concern about the module and the heat sink. I have a c6 host and a heat sink from suvival laser. I have 445nm diode with xdrive driver that is in the module casing. When I insert the whole module into the heat sink and push it into the host...

I have a 5mw green pointer and 1.7w+- 445nm pointer. When I shine them both into the night sky they both seem to go on until a certain point. The point is the same with the both of them. How far is it? I have a theory that its the intersection of a straight line from my eye versus a straight...

I am thinking about following this How to make a cheap 1000mW+ Blue Laser Pointer - YouTube For my first build. I am going to order all the suggested parts from the description. I basically want a bright or 1w+ pointer. I want to keep it around $100. I want to be able to see it in the night...

I had a 50$ order that has been in 'Checking' for three weeks and I checked the site this morning only to find that its offline. I will give it a few more weeks before I call visa and have my finds reversed. Anyone have any info on this place?

I have found post saying that ebay/amazon sell do it yourself laser pointer kits. But I check ebay and amazon and it seems that they dont really sell kits or complete laser over 5mw. Does anyone sell a diy kit? I would like to build 1w or smaller laser maybe using a cree flashlight as a host. I...

Sup guys, and hopefully girls. I just wanted to say hi and introduce myself. I have recently gotten interested in a high power laser after seeing a friends 1.8w laser that he bought from another member here. I just spent 40 bucks on 2-200mw lasers from lazerpoint.com but I have now read that...
