G-Scale Model Train Automation Control

Posted May 18, 2018 by Chris

"As we enter 2014, I thought I would post up a recap of what I’m working on. Primarily I’m developing a wireless method for controlling moving vehicles. In my particular case, this is Garden Scale (G) model train locomotives. However the principles and widgets I’m designing could be used to drive almost anything via real time wireless up to a distance of about 300 ft."

Emanual Version2 – Ready for the Playa

Posted May 11, 2018 by Chris

"…I had a vision of a different kind of vehicle for that year. What I wanted to make was a self balancing extension ladder. You could ride it around the desert while standing on a rung, and then when the dust storms kick up, you hit a button and whuup!, the ladder extends and lifts you right above the low-flying dust clouds. Sounds fun? I thought so."

Building A Polargraph

Posted May 5, 2018 by Chris

"As part of an graduate-level independent study course I am taking through my university’s Art department, I will creating a polargraph drawing machine and installing it in a public hallway for public viewing."

The Ghost Gunner

Posted April 1, 2018 by Chris

"Ghost Gunner is a non-profit open source hardware effort by Defense Distributed. Ghost Gunner builds on the open source community’s existing hard work, including the gshield 3 axis motion hardware, the grbl g-code parser and motion controller, and the legendary Arduino microcontroller. All GhostGunner schematics and design files will be published into the public domain."

300mW DIY Laser Cutter

Posted March 26, 2018 by Chris

"I built this laser cutter after being inspired by [a project I saw] and the design is almost identical, there for I will not go into details about my build but will instead focus on what you can do with it."

Wireless Thermostat/Temp Sensor (With XBee)

Posted February 4, 2018 by Chris

"This post will be divided down into two main sections: hardware and software. I will try to explain with detail while keeping it short, and cover some of the key elements and choices involved in making this project."

Triple 8 H-Bridge

Posted August 28, 2017 by Chris

"This is a motor driver board that can drive 2 DC motors in Forward or Reverse with full speed control. It can handle at least 25 amps per channel continuously at 24vdc. I designed it using a basic H-bridge with 4 switches, 1 switch going to positive (+) and 1 switch going to negative (-) for each motor terminal."

Open Source PLC

Posted August 1, 2017 by Chris

"The PLC is a general-purpose controller with a wide variety of applications. It is useful to the engineer, technician, student and hobbyist. All the source files for the small brick OSPLC are provided, including schematic diagrams so that you can build this project yourself or modify it."

Bark Opening Door System

Posted July 14, 2017 by Chris

"Sleep deprivation has been driving me mad recently. And it’s all down to a new member of the family, our new dog. She barks at night when she’s left out. She barks early in the morning when she’s left in. So once I recognized the patterns of her barking, I realized that all I needed was something that would let her out when she needed to go for a pee, usually around 6:30 in the morning."

Robotic Arm Tracks Hand Movement

Posted May 18, 2017 by Chris

"This past week, I made a robotic arm that tracks your hand in free space using a Leap Motion, Arduino, and node.js. It tracks my hand very well. It is able to pick up stuff and set it down with relatively good precision, although there is definitely some room for improvement."
