I purchased a 5W laser from Sanwu - Spiker. It was my first laser, and I was a newbie to lasers. I purchased 2 goggles with it as well. I've wear the goggles religiously while using it, and make anyone with me while I'm using it wear the other pair. I've never blinded myself, injured my...
I only have one - the Spiker, but I've never seen handheld lasers made as nice as Sanwu makes them. It's nice to see such a good product consistently being made by a company. Yes, it makes me want an all Sanwu collection too.
Has anyone attempted a laser build using a larger portable power source, such as a 40 volt, 5amp Ryobi battery? It seems to me that this could power a number of Nub44M's in an array to make a very powerful portable laser. Just wondering if anyone has experimented with these larger batteries?
I paid a little more for the Spiker (non-saber). I really like the thickness and weight of it. I do need to get that adapter for the beam expander. Podo, how should I contact you to get the adapter that I failed to order? It's not listed as a separate item on Sanwu's website.
ElectricPlasma, no I do not still have the dimming problem. It was clearly a battery problem that took a little bit for me to diagnose. My first set of batteries came from Ebay. One was a good battery; the other has a problem with it. I went to a Vape shop to buy two new batteries and a good...
Who knows, perhaps only a fraction of the mass of the sun is all that is necessary to extend the sun's life by 1 Million years. A million years is a long time for the human race. Besides, no matter what our future generations attempt to do to save themselves from the galactic forces that could...
If we have the technology to move the earth with all of its plants and animals intact to a star comparable to our sun, we would surely have the technology to rejuvenate our own Sun and keep it going for another million years. It might be as simple as feeding it Jupiter and Saturn!
Personally, I think it would work. But, so would a gun. Less liability shooting the murderer dead than with blinding him. But, if all I had was a 1W laser, I'd whip it out and start blinding the murderer! I'd worry about taking my lumps later.
I've been away for a few weeks. I did not order the adapter, didn't know I needed it. Yes, without the adapter, the beam expander is fairly useless on the Spiker. I was going to try and play with it a bit more to get it to work, but, honestly, I was afraid of burning my hand. Ok, so I'm...
I make no opinion on whether or not we live in a "multiverse", as I have no evidence one way or the other to support such an opinion. Although, I tend to doubt parallel or even not so parallel universes exist. However, if there is/are other universes essentially occupying part of the same...
Follow-up. I received my beam expander and protective glasses last Thursday. It had to be re-shipped, but Sanwu did re-ship after it became evident that the missing package never made it to me. The beam expander is also nicely made. I've been playing with it, and to be honest, I'm not really...
Thanks, Nanolaser. The photos were taken with a Samsung 23mp camera with macro. I'm actually still learning how to use it; I probably should have used manual focus for some of the shots.
FWIW, I don't mind if the mods want to move this thread to the "Companies" subforum. I just wanted to put...
The "crap" chargers are useless. Buy a decent Nitecore charger, that's what I did. The crap did not fully charge my batteries, and one battery either came "bad" or was shorted out by the charger.
Here are some photos I took of the laser and its disassembled components. I did not break it down past what I could easily unscrew, i.e. I did not take any of the electrical components or diode out of the unit.
I tried to take pictures of each component so that you could have a better idea...
