sorry dude, but :crackup: Anyway, I'm glad all went well. :)

So your laser ignites matches... I that in completely parallel beam mode? How long did you charge it? I plug it out as soon as the green light appears. Under that conditions, I've never been able to light a match without at least some focusing and I used matches with brown matchheads.:thinking...

That's my LZBH and you can see there's barely any space left.

I have experience with Lazerer only, so I can't talk about other companies. I don't think they're expensive for the quality of the service/product they offer. If I wanted something cheap, I'd buy something from smugglers in the ads that would probably last for less than a year and then start...

Hello. As soon as you see MW instead of mW, you can be pretty sure it's a ripoff. No respectable seller/company will offer megawatt :p lasers. The price is way too low, too. My advice is to save that money and keep saving until you have enough for lasers made by acknowledged companies like...

Yes, I saw it, thanks. It took quite a while for Lazerer to put that info online; there was none before. I think it's a reasonably good cycle. I think you're going to have a blast with this laser. :wave::wave::wave: I don't think you could push in additional 5mm without damaging the spring...

Hey, Valendro, the laser still works like a charm. The batteries work perfect. I never let them drain completely and so far each of them has been charged for less than five times. I don't use the laser quite often, so you get the picture. I've did ton of photography using its ray, and melted and...

It's much more brighter than cheap no name pen lasers, that's for sure, and it's somewhat brighter than "true 50mW" lasers with proper aluminium hosts. However, I thought it will be capable of lighting a dark matchhead unfocused, but I've never succeded doing it. I guess 100mW is the threshold...

The batteries are: blue one: 32.3g, 3.91V red one: 45.6g, 4.03V They've been charged only once so far, and few days earlier, before I used them (the blue one especially) extensively, they both measured over 4.1 V.

Re: How to Make Fog Without a Fog Machine For better beam viewing. "Cheap & Easy for So they sell basically a weak aqueous solution and charge it a lot. Pure pharmaceutical grade glycerol is orders of magnitude cheaper, lol. :) But water can't be used as a nutrient. Glycerol can. I think...

Re: How to Make Fog Without a Fog Machine For better beam viewing. "Cheap & Easy for 1 volume part glycerol, 15 parts water? Isn't that too much? That's basically saturating the room with water vapor. Very high humidity + glycerol = nice environment and food for mold. :thinking: 5 drops of...

Here's the review. Surprisingly, the package came directly to my apartment, something my lazy postal office does almost never. Anyway, I found it on my desk when I woke up, just like I imagined it's going to happen. :san: :D The outer wrap was not glued, so I think it might be that it was...

That's true if you're using aggressive approach with concentrated acid (real PCB bath). Small cavities form and their surface is squeaky clean. The acid doesn't do anything special, it simply removes everything in the path, leaving pure copper surface. Copper tarnishes and that's a fact. It's...

22 days later and it's here. :) I'd like to ask the admins to move this thread to the Reviews section. The batteries are charging at the moment and hopefully, I'll make a review during the day. :san:

Re: How to Make Fog Without a Fog Machine For better beam viewing. "Cheap & Easy for I've stumbled upon this thread and I see none of you got the real info. This was discussed before on another part of LPF so I'll repeat it once again. Glycerol vapors' toxicity is very low. Its main problem...

That works if the oxide layer is very thin. Aluminium foil method is usually used for removing tarnish from silver, but it always requires more conductive electrolyte. Tap water is a pretty poor conductor so sodium carbonate or bicarbonate is added to it. Even then the process takes minutes...

Just use a mixture of equal amounts of muriatic acid dilluted to let's say 10% and hydrogen peroxide from the store (3%). More concentrated mixtures are used to etch copper for PCB printing, but dilluted aren't so aggressive and will remove the oxide layer in half a minute. Pure alcoholic...

People who talk about "laser ranges" shouldn't be allowed to buy any laser above 5 mW of power. It's a clear sign they have no useable knowledge of physics, therefore stronger lasers in their hands become dangerous. When you see someone selling a laser and talking about its range, you can be...

Many other Lazerer's lasers have the focus feature. Actually, I think every larger host they offer has one. What LZBH model is special about is that it has a shutter. That's why it's somewhat more expensive than the other models they offer.

The order has been shipped. I say it's been pretty fast so far. :) GoldPunch, how can I have any, if I've just ordered it? Great Anomaly, go to lazerer.com and check the contact details. It's really not up to me...
