  With the month of October almost here, I have kicked these Halloween projects into high-gear. I previously said that update number four would be all about lighting, but since I just finished the audio portion of Project Trick or Trivia, I thought this would be a good time to tackle the audio portion of Foginator2000. Since Trick or Trivia will be playing triggered audio events based on the buttons, I did not want to muddy the dynamic sound-stage with too much audio. So Foginator 2000 will ...
  Welcome back to the Trick or Trivia Blog. In this installment, I am going to show you how I managed to get the audio portion of this project up and running. I hit a slight bump in the road shortly after setting down to figure all of this out. I had planned on having several different layers of sound playing at once, but have only managed to get a background and foreground set of layers working together, and I think that will be enough.   I had originally planned on running the back ...
Background In this tutorial series, we are going to learn C# using the Raspberry Pi 2 and WinIoT. The goal will be to learn about the C# language by building projects with it. So, think about it as learning through building. As we progress through the tutorial, the projects will grow in complexity and we'll start to create some pretty amazing things.   Why C#? C# is a very popular language, and for good reason. It allows for complex programs to be simply and clearly stated. This allows you, ...

I am a raspberry pi first timer and I want to do a raspberry pi hook up with Christmas lights and music.  I need detailed instructions.  Can anybody provide some good instructions? ...
Just a couple days left!   There's always room for Pi in your Amateur Radio Go Kit. Now you can top it off with the Pi-Go and plug right into your station power.  Great for your embedded auto projects as well@   https://www.kickstarter.com/projects/bobrecny/pi-go-amateur-radio-power-for-your-raspberry-pi ...
  Welcome to installment #003 of Project: Foginator 2000 part of the 2015 Raspberry Pi Halloween Project series here at Element14. In this week's episode I am going to cover the basics of getting the Raspberry Pi Sense Hat up and running, and a very light tutorial on how to push this data to the cloud in order to record and analyze the data. The cool thing about this is that we can simply save all of our acquired data to the cloud, and access it from anywhere!   The Hardware  Be ...
  Welcome to installment #002 of my Foginator 2000 Halloween Project here at Element14. In this week's episode I am going to cover the basics of automating an ADJ VFI1300 1300W Fog Machine via a Raspberry Pi and a Parallax PIR Motion Sensor. The process is fairly simple, and only involves a handful of lines of Python code, so even the code-beginner should easily be able to get this working.     Below is a table containing the parts you will need for this project. In addition to ...
We've been cruelly teasing you all week about a project we're about to kick off here at element14, as we alluded to the brand new Raspberry Pi case we had delivered. But you guys were too quick for us. Although there were a few wry suggestions about what was being delivered -- including a rather excellent notion about building a Raspberry Pi juke box (watch this space) -- most of you astute Pi eaters sussed out that we've bagged ourselves a classic, upright arcade cab that'll soon become ...
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.       ...
  Hello everyone! It’s been a week and I have been working hard at designing and writing the trivia interface for this project, and I am proud to say that after an absence of more than five years from Python, I was successful in getting a decent looking GUI built. Unfortunately I have yet to figure out how I will be randomizing the questions that the device ask trick-or-treaters, but that is something I can work on later in the project. So let’s jump in and take a look at how I ...
We've made this funny project for a German crane manufacturer. It's a PONG game based on the Raspberry Pi 2, written in Python and controlled via 2 heavy remotes for cranes.   ...
Introduction There is plenty of jitter on signals generated using GPIO on the Raspberry Pi and many other computers, and this is due to the fact that Linux can context-switch user processes at any desired point in time dependant on its scheduler (for more information on this, see the Raspberry Pi GPIO Explained guide).   One solution is to use custom driver code, but this is a non-trivial exercise.   Another typical workaround is to offload time-sensitive I/O to external hardware suc ...
Halloween has always been one of my favorite holidays, so much so that I founded a business that makes professional-grade props and controllers for Haunted Houses. This naturally led to Element14 asking me to create a couple of projects that were easy enough for the community to follow along and replicate the project at home. For my second project, I am going to be creating a automated Fog Machine controller that utilizes a Raspberry Pi, and the new Sense Hat. The Concept The basis of this ...
