  • DIY Pick N Place - Final Writeup

    DIY Pick N Place Machine I apologize for the late write up/submission. Due to some unforeseen life circumstances, I missed he deadline. I wanted to say that while unable to meet the deadline or finish this project, I hope to continue and update the community…

  • RangeDetect Rover 6# Final project

    RangeDetect Rover avoid obstacles and change direction to find way out. 1 Introduction This is the project for detect obstacle and path-finding. This can be in-door delivery, or sweeping bot, or home surveillance. 2 Hardware The TMC5272 is a Step…

  • Octoscope

    In this project, I mounted a wireless camera on a slip ring driven by a stepper motor controlled by the TMC5272 controller. Motor controller and camera stream has been integrated in Octoprint to provide 360-degrees view of the object being printed The…

  • Satellite Tracking Ham Radio Antenna Rotator

    I've been working on several different antenna rotor control systems for ham radio and this kit will be used to develop a small satellite tracking system integrating with what I already have built. This project is a mini version of my automatic satellite…

  • Accessible Sewing Machine for Leg Impairments

    This is an assistive tech project for the people who have problem on both legs. In this project, I illustrated my system that makes the sewing machine accessible to all. This is a plug a play solution and user can use it without any modification to the…

  • AVR Part 5 – Connecting Variac and Stepper

    In this chapter, I’ll be looking at my last-ditch attempt to progress my “Make a Movement” design challenge in spite of my medical conditions. As I cannot walk, I’ve had to literally crawl around to make this happen. After all, the finish line is getting…

  • Demanding Stepper Motor Applications

    This project addresses the "Start a Movement" theme by incorporating the Analog Devices stepper motor kit in two applications where stepper motors require precise control. These applications are a connector tester and a thread tapping machine. Intro…

  • AVR Part 4 - TMCL-IDE Setup and First Movements

    It's time to get the TMC5272 plugged in and running, so let's see how the TMCL-IDE works and just what it can do. Installation and Setup I'm running on Windows, so I downloaded the latest version of TMCL-IDE from ADI Trinamic's website here . At…

  • ASM - Working more with the Sensor

    In my project, I am using a flex sensor for detecting the bending of the finger to control the foot pedal. A flex sensor is a variable resistor and we need to convert the resistor value to a proportional voltage output to read it using a microcontroller…

  • AVR Part 3 - Connections and Power

    Hello and welcome back. In this section, I get the connections ready and take a slight unexpected detour from the project. Connecting the Motor In the last section, I unboxed the motor which had four wire connections. This was a little new to me,…

  • ASM - Adjusting Torque and Current Rating

    Tuning Current for a Good amount of Torque After making the linear pressing system with the 3D printed parts and stepper motor I was curious to check it with the foot pedal of the sewing machine. The pedal is not very easy to press and it requires a…

  • AVR Part 2 - Unboxing

    This post will mostly concentrate on the parts provided for this design challenge. Unboxing It was a fine day, the 22nd of November, when I decided to step outside for a bit and saw a box on my doorstep. All of a sudden, without any notification…

  • ASM - 3D Printing and Assembly

    For controlling a sewing machine a foot pedal is used. As I want to control the foot pedal using stepper motor I developed a 3D printed vertical mechanism for pressing the foot pedal down based on the finger bending. I used the following components for…

  • Smart Conveyor Belt for Sorting System - Blog Series and Project Write-Up

    Project Title: Smart Conveyor Belt for Sorting System Project Overview The Smart Conveyor Belt for Sorting System is an innovative prototype designed to automate sorting tasks using sensors, stepper motors, and IoT integration. This small-scale…

  • Thread Tapping System (Start a Movement Design Challenge))

    Intro This is a quick update in the Start a Movement Design Challenge to demonstrate the assembled thread tapping system with both stepper motors running. The 6-32 tap that is in the chuck requires the lead screw to provide 1 inch of forward travel…

  • AVR Part 1 - The Concept

    Welcome to my first project post. My project is called "AVR" and that's not named after the 8-bit microcontroller! Why "Start a Movement"? I decided to participate in this design challenge for a few reasons. The first was simply because it looked…

  • Wireless camera

    The housing for the wireless camera is ready! The case is a slightly modified version of the project available on thingverse ( https://www.thingiverse.com/thing:2254307 ) The camera runs a MJPEG streamer. In this post you can find all the details…

  • Connector Tester Hardware / Software Demo

    Intro This update to the Connector Tester portion of my "Start a Movement" design challenge project covers the completed hardware and software for this machine. Just to recap, the connector tester cycles a connector mating pair open and closed while…

  • Controlling Stepper Based on Flex Sensor

    I want to use a Flex sensor to control the stepper motor based on the bending of the finger. A flex sensor is a low-cost, easy-to-use variable resistor that is designed to measure the amount of deflection it experiences when bent. The sensor's resistance…

  • Implementing StallGuard using Arduino

    StallGuard is a sensorless load measurement technology for stepper motors. Implementing StallGuard in a stepper motor driver eliminates the need for reference or limit switches and reduces the complexity and cost where precise referencing is required…

  • First 3D printed parts

    The software part of this project is already there, so it's time to think about the physical part. As I said, the goal of this project is to build a mechanism that can show the object being 3D-printed from every sides. I have a delta printer, which…

  • Configuring the wireless camera

    For the project I have in mind, the camera must be able to rotate continuously. For this reason, a USB webcam is not suitable and I will make camera from a Raspberry Pi Zero W board and a Raspberry Pi camera module. To integrate the camera in Octoprint…

  • Integrating motor control in Octoprint

    After I discovered how to control motor velocity, I integrated the Python scripts I developed in OctoPi. Installing OctoPi on a Raspberry Pi board is quite straightforward: you can burn the image on an SD card using the Raspberry Pi Imager. You then…
