OpenCV is an amazing piece of software and the newer Pi's are getting the power to run real time image processing tasks, like face detection.           However, OpenCv is not that user friendly, Lets make an attempt to simplify it a little. Most detection scripts need accompanying files that contain the information to identify what we are searching for in the image we just captured. Luckily OpenCv comes pre packed with some of these Haar-Cascaded [The files that te ...
The skull is controlled by three servo's giving it three degree's of freedom, it also has Led's in the eyes to add a dramatic effect [see the later blogs]   Degree's of freedom: >Up/down >Pan [side to side] >Head Tilt     I'm not going to be putting a full wiring diagram because Charles Gantt did it so well in his blog: Trick or Trivia Halloween Candy Dispenser #004 - Building The Candy Dispenser & Servo Coding    Wire it up to these GPIO pins on ...
To keep people upto date:   The Animated grim has just been setup outside and it is epic! I have been mad busy making the thing after breaking a few parts. I will be blogging about the build early next week.   Goodluck with the projects guys, Mike ...
It looks like I am one of the first to receive the Kit, So I thought I would do a quick video of what was in the box:     Thanks Element14 and Dave, the kit looks great and was shipped fast as always! Keep an eye on the main page for future blogs:   Animated_Grim Blog: Home Page [Last Updated 6/10/2015 < British Format] ...
We will be using quite a lot of image processing on this project, lets make life simple.     It it crazy Just How much miss information there is about opencv and the Raspberry pi, many tutorials will guide you thru a installation process that takes 12 hours+ and has library's linked complexly.   Opencv 2.4.1 [CV2] is available in the default Rasbian Reposttory. To Install on Rasbian, type the following into the command terminal:   Type Into Terminal Sudo apt-get update sudo a ...
Why enter the competition >I have checked out a few of the other Halloween projects and they are great! >Many fun Halloween pi ideas just wont leave the back of my mind >The Element14 Challenges are Fun     Project Scope Right, well I’m guessing you have watched the above video. Lets talk about the plan in a little more detail.   Aim: Pi based vision based project that is scary, fun and would make a great project for people interested in the Rpi and vision. I g ...
With running this project on a non existent budget, a lot of the stuff is going to have be  $1 or borrowed temp from another project.   Here is the poor mans "Fog" build. I built this unit as a pesticide doser, by just adding water it will create safe cool mist and by adding a few delivery hoses we should be able to route this wherever it is needed.   Take a look at the Vertical Growing Blog for more info on this mister:   Automated Green House Blog's Home Page [Updated: 6/ ...
This will be the home page for the automated_Grim Project, a part of the PumpKinPi2015 Competition.       Blogs: Animated_Grim Blog:1 - Project Overview  Animated_Grim Blog:2 - Cheap Fog  Animated_Grim Blog:3 - Raspbery Pi and OpenCv the Easy Way  Animated_Grim Blog:4 - Unboxing The Kit  Animated_Grim Blog:5 - Halloween is upon us  Animated_Grim Blog:6 - Wiring diagram and the skull  Animated_Grim Blog:7 - Pi and Face Detection [Or Anything you want ...
I thought I would share my simple design for a fog generating machine, I made this a few years ago as a pesticide doser. It might be of interest to those of you making a PI based Halloween special, just dont add the pesticide!   I could not find any cheap units when I made this a few years ago, maybe there is a cheap off the shelf solution now? but I still prefer using things built than bought. This unit just requires water and 24v to operate, no chemicals needed.       ...
