Re: What to expect (how powerful is the Raspberry?)

So, I guess using Gimp or Inkscape is out of the question? I run both here. They're not exactly blindingly fast, but they're both usable. I DID read somewhere that Quake III runs on Raspberry Pi. Yes. I run that also. It's surprisingly fast and smooth. Definitely very playable. And, if I wanted to,...

Re: x86 image for sd card

[If you need x86 capability, use an x86 machine. Agreed. I've heard of people wanting to run virtual Raspbian on an X86 machine with QEMU, but never the other way around.

Re: I2C and 5V - Definitive answer?

I suppose it does come down to what one considers "good circuit design" or acceptable. Much like some would never go parachuting because there is risk intrinsic in that while others are happy to take the chance. I'd like to be able to agree with you, but good circuit design always means doing nothi...

Re: I2C and 5V - Definitive answer?

Why should something within electrical specs not be done ? As I said, diodes designed to be protection diodes often have strange characteristics, so they can't always be expected to behave exactly like a normal diode under all conditions once you push them in to conduction. Bear in mind that diodes...

Re: Expend RAM via SD-Card Partition

Re: I2C and 5V - Definitive answer?

In the absence of full electrical specs for the Pi's GPIO it would be recommended not to do it. Either with or without full electrical specs, it should never be done, ever! That's one of the basic golden rules that any qualified EE should already be fully aware of. I'd have a hard time trusting any...

5V will kill your RPi Yet others say it won't when appropriately current limited, and same say they are successfully using a Pi in such a configuration. Shoving 5V into a 3V3 logic pin via a current-limiting resistor and hoping that the internal protection diode will save you is an awful way of doi...

If the card you're trying to write to has already had a Pi OS on it, you almost certainly need to format it first with SD Formatter 4.0 setting the Format Size Adjustment option to ON .

Apologies if I'm wrong, but it sounds as though you're treating a Linux computer like a Windows computer and just going off to various websites and downloading things that probably won't even run on a Pi. Nearly everything you ever need for Raspbian is available via the Raspbian repository by going ...

Yes. They should, but read the last paragraph I added to my previous post. I don't trust them in anything based on past experience, so I'm pretty sure that this isn't a Pi-specific issue.

It's highly unlikely that the other two cards are genuinely faulty. I still believe that your problem lies elsewhere, most likely a power issue that's corrupted the contents of the other two cards.

Re: how to change Pi2B from stereo to mono

(10k sounds a little high to me - typical input impedance will be 47kohm, so you're actually making a potential divider and losing a 6th of your signal). The high value was chosen to minimise load on the Pi to irrelevantly tiny levels. A value one-tenth of this would be fine too. As a Pi is capable...

The SD card slot performance can easily be doubled when using UHS-I cards and an appropriate line in config.txt on both the Pi2B and Pi3B. Ethernet 10/100 is what it is. It suffices for hundreds of millions of PC users.
