Re: Cutting the Raspberry Pi A+ board

Well, I bit the bullet and took a dremel to the A+. Its a pretty bad cut. Worked. Obviously, I do not recommend this. Tempted to see how much of this board I can chop off! :D Can't beat an acid test..... :) ...but DougieLawson categorically said "NO" and that £15.50 would be wasted - so he is not G...

Re: Raspberry 2 super computer

Look at hadoop. Some of the things you want can be done to some extent with hadoop.

Then follow some of the hundrends of guides on setting up hadoop as a cluster.

Re: Cloud on Pi

That is not a Cloud. That's just storage with remote access. A Cloud implies some kind of distributed storage and processing which does not apply to a single computer. If you just need remote access to your files, consider ftp or sftp. It is very simple to set up and it uses authentication for uploa...

Re: Configure PiTFT as a system monitor display

Yes, probably because at the start it fills the window left to right until the window is full, and then starts scrolling. I like it that way, but it probably is a little confusing. yes, once it fills the whole screen, then the right edge of the screen shows the latest measurement and it pushes all ...

Thanks. Will give it a go today if I find the time.
Do I need to compile libfb16 or can I just compile raspinfo and ignore the other folders?

Configure PiTFT as a system monitor display

I got a PiTFT HAT from Adafruit and I went through the installation. I have a fairly decent understanding of how it works but I don't know how to customise it to display the things I want. So by default, it creates a new framebuffer (fb1) and anything that goes there is shown on the TFT. The default...

Re: RPI2 stability issues

OK, I would recommend an RMA after you have ruled out the following: PSU/USB cable: Does the red power LED blink at any point? Do you see the square rainbow on the top right of the screen at any time? SD card: Do you have any other SD cards you can test it with? If you cannot rule them out, RMA the ...

Re: RPI2 stability issues

ok, so my recommendation is to stick a fresh image on the SD card, if possible and try your testing regime without changing any settings at all. Dist-upgrade will give you 3.18.7 which is the latest stable kernel. I would recommend you reflash your SD card rather than reinstall a kernel. In general ...

Re: Help needed with GPIO/shutdown process

Have a look here:
https://github.com/headamage/pi-python-shutown

I have put lots of comments in the code. You can edit the GPIO channel to whatever pin you want to use. The program uses interrupts so it is not using any CPU resources while it is running.

There is a serial connection you can use via the GPIO. So yes, you should be fine. You will need a USB to serial cable but they are extremely cheap.
