Pakled posted:https://www.kickstarter.com/projects/1412226584/concealed-carry-awareness-bracelet?ref=newest I have a couple friends with eternal erections for firearms, and they were talking about concealed weaponry laws. You can't have it show, is the rule. Like, if you have one strapped close to your swiftly depleting white rear end, you can't have it accidentally show ("brandishing") if you're in a store and reach high up for that value-pak cereal on the top of the shelf, so you should wear long shirts to conceal. So this silly thing is so you can brag about your firearm without "brandishing" it. Or whatever, I'm not reading the KS site, but getting funds out of gun nuts is like shaking a money tree.

but, like, the whole point in ccw is to have a weapon for just in case you need to defend your life, right? advertising that you are armed seems like it would be counter-productive. dont they teach you to not unholster until youre 100% out of other options? wearing a wristband that shows off that you are carrying seems like a tacit admission that you dont actually need it for self defense, so why do you even need to carry in the first place? makes no sense to me, but so does being in a situation where you need to carry a weapon on your person all the time in a first-world nation anyway

quote:In January, the company discovered that its prototypes failed Apples certification testing, because the device diminished the phones ability to send and receive RF transmissions, forcing it to figure out the cause. It also noted that the device wasnt reliably charging the phones that it was attached to, that it was pushing backer deliveries to March 2017, and that it was suspending refunds while the issue was sorted out

Like obviously it depends on the specific wavelength to some extent but glass is a dielectric, right? Anything microwave or longer should have no problem going through glass, otherwise microwave ovens wouldn't need that metal grille in the door does something special happen with chopped glass fibers in a plastic composite?

Sagebrush posted:shouldn't glass be mostly transparent to rf glass isn't transparent to rf here's a way to visualise this: look at the stars at night and notice how they twinkle. that is the effect air has on light. we have to place powerful telescopes in high-altitude to combat this or even yet put a telescope in space since there is less seeing problems now think about what glass is and then you'll see what i mean

That doesn't really make a good analogy because the atmosphere and a sheet of glass are entirely different materials with entirely different densities and thicknesses do you have a more technical explanation? I'm interested but that one doesn't help

 so maybe not much, but they also said they had some special plastic made so they could have also opted for something stupid. maybe the little glass pieces do something sciency? i/m not a scientist

Sagebrush posted:Like obviously it depends on the specific wavelength to some extent but glass is a dielectric, right? Anything microwave or longer should have no problem going through glass, otherwise microwave ovens wouldn't need that metal grille in the door bingo. a big sheet-o-glass has pretty negligible attenuation at phone frequencies (look at the purple line on page 3 of this) but every change in material results in a change in the propagation velocity. thanks to physics that boundary condition results in some amount of reflection. for glass fibers in plastic those boundaries are also curved and randomly distributed so they cause a bit of lensing and diffusion with the end result being something like this lamp filled with crushed glass:
