Re: How to Install Firefox?

Yes I know I can do that, but this is supposed to be easy to use for people getting to know about computers. It really should work, or at least give an error message to say why it hasn't worked.

Re: Pi 3 - how to detect low voltage?

Thanks Dom,
I have done some digging around and there are lots of references to various vcgencmd commands, but I cannot find any documentation for it, listing all the commands and what they do. Do you know of anything?

Pi 3 - how to detect low voltage?

I am trying to create a program to monitor my various Pi's, temperature, space, voltage, etc. Works for Pi 2 but voltage detection does not work for Pi 3. From info on an earlier post the voltage detection circuit was moved for the 3. Can anyone tell me how to detect low voltage on a 3 within code? ...

No sorry, what I meant was how to disable internet update, so I can let the user set it, just like a standard digital alarm clock.

I just ordered a WD before I saw your post :cry:
Are you saying that you have tried the HDD boot and it does not work with a WD drive?
I will try it out when mine arrives anyway.

Re: Recomendation for Bootable HDD

Yes the Pi has a decent power supply and yes the HDD has its own power supply which was supplied with it.
The WD drives are designed to use an SD card to boot, which is what I am trying to avoid.

Just tried that and it still won't reboot.
Previously it shut down and had both red and green LED's on, now it is just the red one. Don't know if that is significant.
