SSH and RPi Raspbian Jessie PIXEL 25 nov 2016

It seems the SSH default acess in Raspbian has been switched off in the latets (25 nov 2016) release.

But easy to get it going by creating an empty file in the root of the SD card with name ssh (jut that, no extension, no content required)

* SSH disabled by default; can be enabled by creating a file with name “ssh” in boot partition

So another little step to perform when preparing a SD card for headless first boot!

Oh, the system nags about password after enabling SSH:

sudo apt-get remove -y pprompt for the gui prompt

The CLI warning is raspberrypi-sys-mods, delete the file /etc/profile.d/

Installing the Arduino 1.6.12 IDE on Raspberry Pi, with ESP8266 and RaspiDuino

Installing the Arduino 1.6.12 IDE on Raspberry Pi

1. Go to and download the Arduino IDE 1.6.12 for the ARM processor.
2. Open a terminal window.
3. Type cd ~/Downloads
4. Type tar -xvf arduino -1.6.12-*.tar.xz
5. Type sudo mv arduino-1.6.12 /opt
6. Type cd /opt/arduino-1.6.12/
7. Type chmod +x
8. Type ./

The new Arduino IDE will be in the drop down, along with your old Arduino IDE (probably 1.0.5 – which is installed when you type sudo apt-get arduino in a terminal window from the Raspberry). You will notice the difference immediately in the splash screen startup and the window pane header will read, “Arduino 1.6.12”.
