Comment: Faraday cage + repeaters? (Score 1) 293

by valinor89 (#48662533) Attached to: Hotel Group Asks FCC For Permission To Block Some Outside Wi-Fi
I wonder if a building with a built in faraday cage could use specific repeaters inside such cage to, for example, provide cell phone signal. Such repeaters exist. For example I can use the cellphone inside my city's underground subway/tube/metro. I know some kind of repeater is used because such acces has been growing gradualy station by station in the last years.

From TFA: "Yet, the C1’s connector does appear to be fairly compatible, as it uses the Raspberry Pi-compatible, open source WiringPi library for C/C++ or Python developers. The project notes that only pins 37, 38, and 40 are not compatible with the Pi B+, as they are dedicated for analog inputs."

No you missed your physics classes.

CIncreasing the power and repeating will make no difference whatsoever. If there is no "line of sight" then laser transmission without an optical wave guide (aka a fibre optic cable) is a none starter.

For the purposes of free air laser transmission light only travels in straight lines. That is no gravitational lensing, and no fancy ultra modern optics which basically are of no use in this scenario.

So repeat after me you idiot no line of sight no transmission.

That is true if you live in vacuum...

The athmosphere will scatter the laser light. If you keep increasing power you might detect that light even if you have no direct line of sight... or melt the planet.

For me the real draw for me would be that a poorly written "falling snow" effect written in JS brings all my tabs to its knees. Oh, and sometimes it doesn't hang ang continues doing its thing slowing down everything. This way the usual alert of a hanged script does not appear...

My 8 month old Win 8.1 install is as snappy as the first day and has only decayed because my SSD has a bug. (SAMSUNG 840 EVO) I thought my install was getting slow but after a SSD refresh it is almost as snappy as the first day. Has it decayed? Most likely, but when the difference is 1 or 2 seconds at startup you hardly notice.

Comment: Cheap hd progectors anyone? (Score 1) 439

If the frame of the screen is a problem why not use well calibrated ( i mean well put together ) cheap hd progectors. I know they are not so HD as a 30" but you could instead have a super-ultra-mega large image at a good resolution. Or a not so big image but of super hight definition. The trick would be adjusting the borders, coler or whatever, but that would be a bigger issue with framed screens.
