This post is about the Arduino/Genuino Board 101 - the Intel Curie Module development board. It is a not an introduction to Arduino, AKA Arduino 101. IntroductionThis post is just a quick introduction to the Arduino 101. I plan to do...

Introduction to the ProblemThis tutorial will show how to drive a Pololu style stepper (A4988) driver using a timer interrupt. This method is non blocking, efficient, and as far as I know is pretty much what most 3D printer firmwares...

I wanted to share my image of ROS Indigo for a Raspberry Pi B+. When I tried a couple of images I found online, none of them seemed to work, so I had to make my own. I will warn...

This is a quick post about changing the MOSFET in an AR6400. This appears to be a a fairly common problem people have with RC airplanes such as the Hobbyzone Champ or the Parkzone P51 Mustang. Symptoms include elevator or...

Recently I was tasked with trimming and combining some videos for work. We had filmed 16 hours of lectures and needed to make them ready to be published. Unfortunately the cameras we used split the video into 19 minute segments...

This will be a fairly short post. I just wanted to get this out there in case others are working on this over Christmas. I may update this later as things progress. This all occurred yesterday 12/24/2015.My mother received a...

DisclaimerI will begin by saying, if you are thinking about printed a disc golf disc to get into disc golf, don't. Go buy a nice 165g dx shark online for $10 and know exactly how its going to fly when...

I wanted to take a few minutes to compile a list of a few useful tools for RepRap 3D printing. I do this because I have been fortunate enough to learn a lot about the tools of the trade from...

This is Part 4 of my Replikeo Prusa i3 build account. This post will cover the initial modifications I made to the printer, how they effected print quality, issues I had with those modifications, and work for the future. It...

Part 3 will cover my wiring of the Replikeo Prusa i3 Rework (mostly following the wiki page). Then I will cover my setup of the Repetier Firmware. I'll save first prints for Part 4. If you are interested in the...

This is not so much a finished post as it is a place to record progress. Use any information found on this page at your own risk.IntroductionI have been using GNU Octave in place of MATLAB on my laptop for...

IntroductionA quick and dirty post documenting an Octave "fix" for a problem I was having. Running GNU Octave version 3.8.2-5 from MXE installer found HERE on a Windows 7 64 bit PC on 3/10/2015.The ProblemThe output of GNU Octave as installed above...

IntroductionThis is the third section of the iRobot Create tutorial. If you have not completed the first and second sections, I would recommend that you go back and do so by following the links below. They provide more insight into...

Part 2 will describe the process of building my Replikeo Prusa i3 Rework. Having already taken inventory in part 1, I will continue following the wiki instructions with Y-axis assembly. Below are the pictures from the build.Y axis assemblyY axis...

About a month ago I decided to build a 3D printer. This only left me with the task of deciding what kind of printer to build. While I had dealt with the Makerbot we have at school, I did not...

Today I will be linearizing a Sharp IR Ranger. More specifically, I will be using the Sharp 2YOA21 F 04.First, a quick word on why we would want to do this. The Sharp ir rangers are a very effective means...

The other day I was starting up my computer in a rush before class. As I waited for all the "necessary" startup programs to start up, it hit me. Wouldn't it be great to be able to a prioritize the...

This was a quick afternoon project that I worked on a few weeks ago. The beginnings were pretty simple. I was digging through the basement and found an old 12v cordless drill whose batteries had died. Being me, I decided...

This project is a spin off from my PPM decoder project. The overall goal is to translate the individual PPM signals from an RC receiver (like THIS one) into usable data that can be sent via serial, I2C, or a...

In this post I will detail how to decode the PPM signals from an RC receiver using an Arduino. Specifically, I will decode the signals from a 6 channel OrangeRx receiver using an Arduino Mega 2560 r3 and my custom...

This is my first "reader requested" post. A reader sent me an email asking me to do a post about controlling a stepper motor using a shift register, and here it is. In this post I will specifically discuss controlling...

Recently I got my DHT11 temperature and humidity sensor working with my Arduino Mega2560. If you are interested in that, check it out HERE. However, while that was all well and good, I found it a bit impractical. While I...

In this post I will be playing with the DHT11 Temperature and Humidity Sensor with my Arduino Mega 2560. While a DHT22 could also be used, I used a DHT11 mostly because it and it was cheap. I think I...

Today I will be taking some time to briefly revisit stepper motors. Recently I have been trying to map out the boundaries of my ATtiny capabilities, and it occurred to me that I have never gotten my stepper motor working...

In this post I will show you how to cheaply  make an I2C sonar sensor for your Arduino. This will be accomplished by making an I2C controller for an HC-SR04 sensor out of an ATtiny85 (or ATtiny45). Both the sensor...
