Re: Commercial Use of the Pi

Look up wave/particle duality, the standard model, quantum electrodynamics etc. All this stuff is pretty much a done deal - experimentation has confirmed all of it, so as theories they are pretty much as good as they get. Of course, quantum physics is so counter intuitive that a lot of people think...

Re: Commercial Use of the Pi

321, Depends what you mean by "scattering". When it comes to the propagation of radio waves, or any other wave, the main things are diffraction and reflection. All of which depends on many factors, wavelength, materials, geometry, physical size of objects etc. All of which makes it a bit hard to kn...

An alternative to that is cutting rectangles out of big...

Re: Run Program/Script from GUI desktop without the 2nd step

A different approach.

Do you have an icon which calls the terminal and displays the behaviour you want?

Perhaps locating the Terminal icon might be a start?

Re: wifi connection on Rpi 3 B

Eg did you use the desktop network icon, or have you searched for instructions which told you have to set these up using the Command Line Interface (CLI)? As you can imagine theres a few different ways to set things up, s...

Re: Commercial Use of the Pi

Actually it's the other way around, 5Ghz penetrates walls, and bodies, better than 2.4GHz. That's how it goes with shorter wavelengths. Also the 5GHz range is less. You should not worry about the 2.4Ghz resonating your water. The energy levels are minute and it only a tiny heating effect anyway. Yo...

Re: NAS shares does not mount after reboot

Actually you are probably right, I think you can also call scripts after the network is up, by setting a script to run in one of the CLI network settings files as well.

Re: Commercial Use of the Pi

I hope to see 5GHz in an upcoming model as someone else suggested on here, 5Ghz penetrates walls better than 2.4GHz which for IoT things would be better and ideally like some routers offer, having the option to switch off 2.4Ghz because I'm not too keen on resonating the water inside me, even at low...

LTI, if its still online, only 3 pulses, speed readings can be obtained from a stationary object by sweeping the device along a fixed object like armco barriers or court room walls if the court room is big enough. The patent even admits it can get a speed reading from a stationary object! ;-)
