3D Printed Planetary Gears

I wanted to try and print some planetary gears to try and make my 4th axis work better.

RepRap - 3D Printer

Here's my journey of building a Reprap 3d Printer. Took about two weeks to get to the point where I was printing and I am still tweaking things to get good prints but it's working well enough to share :)

Timing Pulleys

I am working on a project for my Enco Mill Drill Lathe - it's a Power Feed driven by a Parallax Propeller and EasyDriver - part of the project involves making some Timing Pulleys to hook it all up! So this post is about the Timing Pulleys! Check out some pictures and videos!

Parallax Propeller Microcontroller

Written by Jamie Cunningham

Published on 27 October 2010

Yes - a new category for another hobby - I keep telling myself that it will all come around full circle one of these days! So I've been looking into making my own stepper motor driver and controller and this is all in the works, but one thing I also started looking at was microcontrollers that can be programmed easily and via the USB port of my computer for controlling the steppers too.

The Parallax Propeller chip is just such a chip. Its eight processors (cogs) can operate simultaneously, either independently or cooperatively, sharing common resources through a central hub. The Arduino is also a very popular microcontroller amongst hobbyists, and I may very well get into that one too, but I chose the Propeller because it has 8 cogs for running your programs in - basically like an 8 processor chip that can run 8 things simultaneously. So for now, in my limited experience and exposure, the Propeller beats the Arduino.

I ordered the Propeller Education Kit and have been playing with it for a while. I've also had an electronics kit from Radio Shack for a while. Since the Radio Shack kit has a bunch of common components on it already, I decided to re-purpose it for my Propeller development board :)

Here's a picture of how I have it set up!

and here's a quick look at my "Electronics Workbech" which is basically just a fold-able table :) I am in the process of designing a new office cabinet system and will make sure I have room for the electronics stuff!
