Raspberry Pi Projects

Halloween is one of my favorite holidays here in the US, and so much so that I spent a few years of my life thinking up and building smart Halloween props and animatronics for the haunted attraction industry. I won’t go too deep into the details of the business, but a few friends and myself founded a company a few years back with the “help” of some investors. It was my first tech startup, and like many tech companies, we had the hardware and software to revolutionize a decades ...
  Enter e14's 2016 Costume Contest Here!  IntroductionWriting the final post for a project is always tough for me because I constantly second guess myself on whether or not I could have spent more time on the project, or if I have covered everything that needs to be covered. Fortunately, I can write this post knowing that I could not have spent more time on this project, because I ran out of time two days ago. My original deadline for this project to be complete was actually two days a ...
  Enter e14's 2016 Costume Contest Here!The Raspberry Pi Hardware    As I mentioned in the first post, I will be using a Raspberry Pi 3, and the Raspberry Pi 7-inch touchscreen. So before I can get started with developing the program and lighting effects, I need to get the Raspberry Pi 3, and the touchscreen mated together. I won't walk you through the process on how to set this up though as there are many of these tutorials here on Element14 already such as this one from my frie ...
  Enter e14's 2016 Costume Contest Here!   There are only a few holidays here in the US that I actually participate in, with Halloween being my favorite by far. Many of you reading this might remember my two projects from last year, Foginator2000 and Trick or Trivia. They were both fun projects to build, and I learned a lot over the two months it took to build them. This year Element14 has asked me to build another project for Halloween, specifically a costume. Over the past week I h ...
  Welcome back to the Trick or Trivia Blog. In this installment, I will show off how I built the candy dispenser that will set beside the tombstone. Unfortunately this part of the project did not turn out as I had planned because I could not find the type of bowls I was looking for. I did managed to cobble something together that works, and I will be able to build a better version for next Halloween.   My original idea was to use faux concrete flower urns that typically can be found ...
  Welcome back to Project: Foginator 20000! In this installment we are going begin wrapping the build up by moving everything from  the breadboard, to a prototyping PCB, and then placing it all into an enclosure. Then we will wrap everything up with a demonstration of the final code. There will be one more installment after this one, which will include actual data from Halloween night. I will also finalize the bill of materials in the final post as well.     The Parts  ...
  Welcome back to the Trick or Trivia Blog. In this installment, I am going to lightly document the process I used to build the faux tombstone that will be used to hold the Raspberry Pi 7-inch touchscreen. My original plan was to buy a 5-foot tall Frankenstein statue, or some other tall halloween figure. Unfortunately I was unable to find anything locally that fit within my budget of $100 for this segment. After talking to a few friends, and watching several videos on YouTube, I decided to ...
  Welcome to installment #005 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 demonstrate how to get Neopixel (WS2812B) LED modules working with the Raspberry Pi 2. Unfortunately as you will see, this is an almost impossible task as the previously working library is only compatible with Raspberry Pi versions up to the Model B+.   Below is a table containing the parts you will need for this segm ...
  Welcome back to the Trick or Trivia Blog. In this installment, I am going to cover the candy dispensing mechanical assembly, as well as the coding to get the servo up and running on the Raspberry Pi 2. Up until now, all of the parts needed to build this project were able to be purchased from Newark.com or MCM Electronics, but this portion will require a 3D printer or some handy inguinuity and minor skills with wood working equipment. I have included both the printable .STL files as well ...
  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 ...
  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 ...
  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 ...
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 ...
