Re: Getting IceWeasel caused me to be unable to log in.

Try rebooting after upgrading everything, then install IceWeasel.

You can get mixed results if the Pi upgrades certain things to do with the OS, and you don't reboot before installing other things.

Re: Using wifi dongle with pi zero

Most wifi dongles work out of the box. The only real issue I've had, was with one that doesn't want to play nice with my cheap USB hub (spammed the network for no reason, but worked fine when plugged directly into my Pi2). But given that they're cheap aa chips these days, it's not going to hurt to g...

Re: Running DC motors off PI

Try something like this:

Take note of the low signal voltages (since other relay boards require 5V to trigger the relays).

Can you post the contents of your wpa supplicant file (minus the passwords)? All of the issues I've had with it have come down to simple typos, or quotation marks in places where it won't accept them.

Re: Extreme temperature monitoring

It all comes down to the sensors you can find. The easiest solution would be a NTC Thermistor combined with an ADC. The ones RS stocks only go down to -80C though, so you may have to do a bit of research on where to find more cold tolerant ones. That's assuming there are any that go down that far (y...

That depends entirely upon how you're sending it. Are you using floppy disks? CDs? DVDs? Flash memory? Blu-rays? Infrared? Some type of specialised hardware? If it's over a network, you only need something on the Pi to accept the connection and deal with it, whether it's streamed or just a file tran...

Re: Pi won't boot or reboot until I remove HDMI cable

I did read somewhere a while back about some HDMI devices potentially feeding power into the Pi. If your TV/monitor is doing that, then it at the very least, you should be able to check the voltage on the 5V rail with and without the HDMI cable plugged in. Another possibility is USB devices you have...

They're not that big. That's roughly the same size of the holes that the Pis mounting holes are. They're closer to 1mm (if that).
