Re: Why Not Have Pi Zero Made by Newark/element14?

because the price of the zero does not give them enough profit, they have declined to sell and distribute the zero. So even requiring that they be bought in packs of 10, they still won't do it? By the way, the zero, and the new 3B are made in the same Sony factory in Wales. Has Sony UK become a who...

Re: New addition, a little disappointing

My Pi3 came in an anti-static bag wrapped in tissue paper and in a jiffy bag. No mechanical protection for the device at all! Consider your plain white box a luxury! Anti-static bad and tissue paper!

You can run your Pi 24x7. I have Pi's I havent turned off since 2012. To get your motor turning 3 times a day, I would do one of 2 things: - create a python program which runs all the time and checks the time, when its time to turn the motor it does - create a python program which just turns the pro...

Re: using the GPIO command

When I use the gpio command, I tend to always use the -g option, which allows you to use the standard BCM pins numbers.

So if I wanted to turn GPIO 4 'on' (i.e. set it high), I would use:

Code: Select all

gpio -g mode 4 out
to turn GPIO 4 to an output, and

Code: Select all

gpio -g write 4 1
to set it to HIGH (i.e. 1)

You could write a command line program to edit the config.txt file ;) but you would still have to reboot!

It might be helpful if we break down the command: sudo cp /full/path/of/file /lib/firmware/rtlwifi/ sudo - use this to run the command as a super user (admin) cp - this is the copy command /full/path/of/file - this is the location of the file on your USB stick you want to copy /lib/firmware/rtlwifi/...

Re: ALPR

The picamera module states you can encode using "mjpeg" as well as "h264" http://picamera.readthedocs.org/en/rele ... #piencoder that might give you more success, but you will have to roll your own code.

If you have the latest version of Raspbian, the Minecraft Pi API python library (mcpi) is Python 3 compatible.

Its important to keep software on the Pi up to date.
