Wait a second what if you **** a wire around **** and then **** it backwards to create ****? Its genius EDIT: Censored potential giveaways for this soon-to-be-provisionally-patented idea

Nobody makes yellow handhelds anymore that I know of... Contact CNI and get one of their tried-n-true $400 10mW modules and mount it into a host from SL (buy a few and see which fit best, can return the ones that don't work out). With such an expensive laser diode, you might as well experiment...

If I ever got $2000 out of somewhere and have no use for it, I'd make a cordless, backpack-mounted fiber laser assembly that can cut steel (probably 500W)... Obviously contingent on the high-powered eBay modules I'm eyeballing still being around and me not breaking any fibers else I need to...

On another topic, has anybody seen this before?: How much does the cheapest 200W IR fiber laser module cost?

As long as you get the superglue perfectly positioned, it should work But if you mess it up you'll need to give the phone an acetone soak which might ruin plastic (if there is any, if not no worries)

Lol that red beam looks like it was added in photoshop That's probably because the 3000mW of red is close to the Fechner limit for the brightest possible perception of red

Worst comes to worst you could buy a "replacement" laser diode for a projector, a cheap "flashlight" (laser) host kit, and then assemble a laser yourself But if you don't fear customs China is best for prebuilts imo

Yeah I love red as a wavelength but the beams are so darn dim

I think it means "feeler" in more colloquial terms As in the OP is trying to get a feel for whether there are people in Australia willing to buy their lasers

Well that escalated quickly

Yes but, for instance, how does NASA manage to communicate with probes on the surface of Mars all the way from Earth? They need to be using some sort of focused radio-wave (possibly "coherent", but low divergence/high gain for sure) laser no? I suppose the other question to ask is; is it...

I preface this by saying I know more about how visible light is produced than how radio waves work, so not much at all lol... I know that with sound waves, one can approximate a "laser" beam by producing an extremely high pitch oscillation and then passing it through a slit. Meanwhile with the...

Here's a use I doubt has been mentioned before: a scar-free prodding tool to keep you awake when you have to stay up all night but have no coffee left

With acrylic lenses, once you get smoke on them with a higher-powered laser they're toast Glass is the way to go, just buy an extra fat screwdriver to unthread the old lens

As long as the wrap is perfectly non-wrinkled, the beam quality should be the same after passing through it (same with tinted glass) If you want to make it look good though, it might be better to dismantle the front of the laser (if possible), insert the wrap (or tinted glass from cheapo...

Rich (Lifetime17) is the go-to maker, DTR's shop still sells but DTR himself is inactive

For something so low power, you could just add some tinted saran wrap to the front to reduce the power to your liking

I am not in any way affiliated with them (and you really should be getting safety goggles from Survival Laser), but maybe one of these could fit your [for 15-20 ft burning distance] small budget: https://laserpointerstore.com/collections/1w-5w?sort_by=price-ascending

As long as they all output the same voltage and have the same C-rating, you can mix and match

Keep the updates coming, can't wait to see the first test fire
