Re: Why is everything so difficult?

I’m glad that there are voices saying every OS/platform has problems- so it boils down to different problems. Also Pi is supposed to be educational; at its simplest it is no more complicated than installing W98 was back in the day (easier as far as I’m concerned) except as you master it you won’t be...

Re: Why is everything so difficult?

I wake up every morning and ask myself why everything is so hard, and every night I go to bed with that question unanswered. It’s been like that since I found out Father Christmas didn’t exist. I spend most of my life in the MS Windows environment, where things as supposedly easier, in reality the t...

Re: Coffee machine power supply

I think you need to draw a plan and explain what you really mean as a coffee machine. My background is in catering and it surprises some to find catering uses a lot of technology (I was using touch screens back in 1992 for example). Firstly you need to understand the science of coffee, for some peop...

Thank-you very much for this, as it is within my level of competence- that’s not to say I won’t be back with questions but getting started is often the hardest part.

This one works on the Pi2, came quickly and works to the limit of the Pi2 and WiFi;

Re: HELP v confused Dad [HDMI no signal]

I’m an idiot and I got my Pi2 to boot. While I’m using a HDMI to VGA adaptor I found it all quite painless- this makes me think something obvious has been missed. Does the HDMI cable work, is the mSD card present and correct (with NOOBS) and is the power supply correct. I’m not bragging but I had mi...

Re: Wifi direct connection between PC and R-Pi 2

Connect both to your home router/WiFi and use that. You could mess about setting up your RPi as a WiFi access point and connect your Win system to that. But it is much easier for a direct ad-hoc connection with a simple cat5 cable between your RPi and your Windows system. Would you just use a cross...

Re: Pi Zero Availability

It seems bizarre people are so desperate to get the Zero, I can’t see a reason why you couldn’t use a different Pi to prove a concept and wait for the Zero to become available- by then you’ll have done all the software and hit the ground running. What is it that people must have a Zero? Am I missing...

Re: SD cards

I noted that people seemed to be using class 10 mSD cards so went with that, as far as I know the Class rating is just the minimum MB/s write speed, not the read speed- and of course there’s always variation on read/write performance due to file size and so on. I’d say try a class 4 if you have it t...

In addition to the 40-pin GPIO connector solder pads, there are a pair of solder pads to allow the Zero to be rebooted when connected momentarily, and a pair for the NTSC/PAL composite video output available on all Pi models. So, it is possible to solder to those latter two pads a thin 75-ohm coaxi...
