Re: I need help to run windows games on a PI.

great. now I've wasted £60 worth of money for a stupid computer that can't even run .exe files. pathetic. .exe files are a format specific to Microsoft. More to the point, Windows only runs on the Intel/AMD x86 CPU architecture. All Pis use CPUs built to the ARM architecture. The machine language i...

Re: Raspberry 3 B needs a cooling system?

I don't use heat sinks or fans on any of my Pi3Bs and they run fine. So...unless you're going to run it really hard or live in an extremely hot climate, no--you don't need a heat sink of fan.

Re: Pi 3 painfully slow (Raspbian)

The Pi CPU is a 'RISC' style machine, so the GHz should be 'discounted' by about /5 ... so 1GHz Pi is about the same as a 200MHz PC .. i.e. what we used to run Windows 95/98 on ... You may have run Win98SE on a 200MHz system but I still have my Win98SE machine that I built with a 1GHz P3 and 512MB ...

Re: Pi 3 painfully slow (Raspbian)

It may have more to do with what you're used to and what your expectations are. I've found that Pis (all the way back to the Model B with 256MB of RAM) have acceptable performance for the tasks I use them for. However, I have never expected a Pi run like a 2.5+GHz x86-64 system.

I suppose it's worth noting that IBM came to dominate the mainframe market (70% market share) with so-so hardware but very good support and pretty decent software. At this point, the Pi is far and away to most widely sold SBC (over 90% of the market, at a guess) with good support and solid, well mai...

Re: zero vs orange pi?

Those sound like questions better asked on an "Orange Pi" forum (if there is one...). And note that a quad-A7 system is *not* comparable to a Pi3B. Sure it's quad core, but the A53 cores of the Pi3B are much faster, per clock cycle, than A7 cores.

Re: Introducing Raspberry PI for children

In addition to the list above, see if there is a CoderDojo or Code Club near you. If not, consider joining forces with the other parents (the ones who told you about the Raspberry Pi) and starting one, or an equivalent to leverage the knowledge of other parents.

Re: Extremely New member

Given the level you say you are starting from, get a Pi3B, learn to use it and then decide where to go from there. A car USB adapter, such as you describe, will work, so long as it will provide enough current for the Pi you use and all of its attached peripherals and maintain a 5v output.
