Python on Raspberry Pi + Camera Module to take photos for timelapse

I finalized my Python exercise to take photos and generate timelapse mp4, run on Raspberry Pi (Raspbian Jessie) with Camera Module installed.


To run the Python on update Raspbian Jessie (2016-03-18), we have to install python-imaging-tk:
$ sudo apt-get install python-imaging-tk

In you desktop, create a shell script, doLapse.sh, and make it executable to run the Python code. Such that you can easy run it.

doLapse.sh
cd ~/pyLapse
python2 myPiLapse.py

The myPiLapse.py is the Python script (Python 2) to take photos. Select "Timelapse" tab and click the "Start TimeLapse" button to start and click the "Stop TimeLapse" button to stop. All the photos will be save in sub-directory named with timestamp.

Download, install and boot-up Ubuntu MATE 16.04 on Raspberry Pi 3



Ubuntu MATE 16.04 for the Raspberry Pi 2 and Raspberry Pi 3 is available now. This post show how to download, install and boot-up Ubuntu MATE 16.04 on Raspberry Pi 3.

- Visit https://ubuntu-mate.org/raspberry-pi/ to download the image of Ubuntu MATE for the Raspberry Pi 2 and Raspberry Pi 3.

- If you direct download the image, make sure the SHA256 hash matches. To generate the SHA256 of the downloaded file in Windows 10, enter the following command, compare with the SHA256 hash in the download page.
> CertUtil -hashfile ubuntu-mate-16.04-desktop-armhf-raspberry-pi.img.xz SHA256


- Write to SD card using Win32DiskImager.


- Insert and run on Raspberry Pi 2 or 3. This video show it boot-up on Raspberry Pi 3.


Remark:
- No cable network connection in the test, so have to connect Internet via Raspberry Pi 3 built-in WiFi adapter after second reboot.
- The MicroSD used is:
Kingston Micro SDHC 32GB Class 10/U1 (Up to 80MB/s Read)
(KINGSTON SDC10G2/32GB - 80MB/s)

Ubuntu MATE 16.04 for the Raspberry Pi 2 and Raspberry Pi 3 is available now

Ubuntu MATE 16.04 image for the Raspberry Pi 2 and Raspberry Pi 3 is available to download or build yourself.

You’ll need a microSD card which is 8GB or greater to fit the image. The file system can be resized to occupy the unallocated space of the microSD card, on Ubuntu MATE 16.04 this can be done via Ubuntu MATE Welcome.

NOTE! There are no predefined user accounts. The first time you boot one of the desktop images it will run through a setup wizard where you can create your own user account and configure your regional settings. The first boot is quite slow but, once the first boot configuration is complete, subsequent boots are much quicker.

Known Issues

  • During first boot configuration Ubiquity does not prompt to join available WiFi networks.
  • Upon completion of the first boot setup WiFi doesn’t work, at all. Reboot and WiFi will be available.

Both these issues will be addressed in Ubuntu MATE 16.04.1 for Raspberry Pi 2 and 3 which is due in late July.

Download HERE.

Disable Camera Module LED

To disable Camera Module LED, edit /boot/config.txt with sudo right, add the line:

disable_camera_led=1


Work for me on Raspberry Pi 3 + Camera Module running Raspbian Jessie.

Setting DISABLE_CAMERA_LED to 1 prevents the red camera LED from turning on when recording video or taking a still picture. Useful for preventing reflections when the camera is facing a window. ~ reference: https://www.raspberrypi.org/documentation/configuration/config-txt.md

Raspberry Pi Camera V2 released

Raspberry Pi Camera V2 released, visible-light and infrared cameras based on the Sony IMX219 8-megapixel sensor, at the same low price of $25.

Here is a video show how it run remote run on Raspberry Pi 3 with Camera Module, from Android phone. Where the phone act as WiFi hotspot, and remote login Raspberry Pi with aRDP app to run the script.

The Raspberry Pi 3 (with Camera Module) powered with portable battery, such that I can bring it outside. It installed with RDP and config to connect to my WiFi hotspot automatically.

Getting Started with Raspberry Pi Zero

Getting Started with Raspberry Pi Zero

Key Features
  • Get started with Raspberry Pi Zero and put all of its exciting features to use
  • Create fun games and programs with little or no programming experience
  • Learn to use this super-tiny PC to control hardware and software for work, play, and everything else
Book Description
Raspberry Pi Zero is half the size of Raspberry Pi A, only with twice the utility. At just three centimeters wide, it packs in every utility required for full-fledged computing tasks. This practical tutorial will help you quickly get up and running with Raspberry Pi Zero to control hardware and software and write simple programs and games. You will learn to build creative programs and exciting games with little or no programming experience. We cover all the features of Raspberry Pi Zero as you discover how to configure software and hardware, and control external devices. You will find out how to navigate your way in Raspbian, write simple Python scripts, and create simple DIY programs.

What you will learn
  • Understand how to initially download the operating system and set up Raspberry Pi Zero
  • Find out how to control the GPIO pins of Raspberry Pi Zero to control LED circuits
  • Get to grips with adding hardware to the GPIO to control more complex hardware such as motors
  • Add USB control hardware to control a complex robot with 12 servos
  • Include speech recognition so that projects can receive commands
  • Enable the robot to communicate with the world around it by adding speech output
  • Control the robot from a distance and see what the robot is seeing by adding wireless communication
  • Discover how to build a Robotic hand and a Quadcopter
About the Author
Richard Grimmett has always been fascinated by computers and electronics since his very first programming project that used Fortran on punch cards. He has a bachelor's and master's degree in electrical engineering and a PhD in leadership studies. He also has 26 years of experience in the radar and telecommunications industries, and even has one of the original brick phones. He now teaches computer science and electrical engineering at the Brigham Young University, Idaho, where his office is filled with his numerous robotics projects.
