Mostly because you're making all these wild claims and posting absolutely jack shit to back them up (as above) .. lasers are generally considered a scientific topic, and as such, majority of users here aren't going to believe anything unless you can provide at least a slither of...

Thought you'd finally gone to Altium ARG :D

If you look on their actual rep page, you'll see the number of points right at the bottom increase. Rep power is how many points a certain user will add/subtract, so you for example right now would have added 3 rep points. I'm not sure how Ave has it set up, but you can gain rep power based on...

It is a bit of a jump right in approach, but I myself tend to learn a lot better by just doing things instead of reading about doing things. If you can follow a datasheet enough to calculate component values and build one of the example schematics they give, it'll give you a good idea of what...

All my electronics "experience" comes from just experimenting for years and years. Read the occasional book, read lots of forums etc. One thing Sig didn't mention was datasheets - every component has one, and most IC's will also have a few example circuits in them, how to calculate components...

They're only selling <5mW pointers for the next few months, presumably to just move stock, after that they're stopping completely.

Like aliens give a shit about what we're doing :D

You're looking past the point guys, their main motivation for no longer producing them is they are probably at best 2% of their sales .. it's just not profitable for them to keep doing it. The fact pointers are also becoming increasingly illegal in many places is probably part of the reason why...

Pointers are such a teeny tiny part of CNI's sales I'm surprised they sold them to begin with. So yes, get them while they last :p

The vapour is just water vapour (not steam), so it does sink already :) And yes, you could. However it'd be a lot more work to make it .. functional, I guess. The fog condenses on almost anything it touches, so you'd have water dripping from the top you'd have to contain, and also the fan at...

85 / 3 = ~$28 .. you can get all those colours separately INCLUDING drivers cheaper than that anyway.

Done a bit more work on this, it's pretty close to completion :D Mounted the electronics on their panel: "Interface" is simply a RGB LED to indicate things like when the reservoir is empty/full etc, a RJ45 jack for the remote, and a power input. I had originally just glued all the edges...

You could probably use some ND filters as goggles if you could find a way of attaching them over your eyes - but it's still no real guarantee for a direct hit. It's just one of those things you have to take a lot of caution in doing. Even a diffuse reflection at close range isn't too big a deal...

1. There aren't really any options for safety goggles in this case - but what's the point of a laser show if you can't see it anyway? 2. No. As long as it's going over the top of everyone's head, and there isn't any mirrors on the wall or in it's path that could possibly send stray beams into...

Yeah, seems to give the best contrast. I'll be using a 520nm laser in it permanently as green is better than red and 445 though.

A few more pics, and a vid: fiKr5B87KBE

Laser projector :) I have a few line lenses coming in the mail so I can set up something a bit more permanent.

Let me know if you're ever in Townsville :p

That's epic! The cross section looks basically identical to satellite/radar images of cyclones/hurricanes, too.

Ever seen the cross section of a tornado? If only the pics could do it justice, it looks 100x more awesome IRL :D
