I’m an assistant teaching professor at Michigan Technological University, so most of the content shared here is linked to that in some way, shape or form. However there may be some odds and ends. Click a class to learn more:
Here are some of my latest teaching-related posts:
The following utility generates a maze that can be embedded into memory on an ARM THUMB ready micocontroller. The objective is to parse the data and fine the path from the bottom left to the top right. The solution is given for comparison.
A project specification (shortened as “the spec”) is a tool / document used to communicate what the intended outcomes of a project are. The spec is methodical in it’s construction in that it carefully presents what each feature of a design will be how it will be quantified, and how many points execution of that feature will earn the engineer / maker. Project specifications are a tool created for the sake of systematically assessing broad open ended projects.
Each 3D Printer is slightly different, but in terms of FDM printers, most of the core components are the same. Of course once we get into different or Novel deposition methods, things can get different. Let’s take a look at some of the core mechanisms for the big 3 of 3D Printing (FDM, SLA, SLS).
The concept behind OpenSCAD is that your 3D model is defined as a script. That’s actually what the S stands for in OpenSCAD: Open Scriptable Computer Aided Design. By using basic shapes and transformations, you can design all sorts of neat stuff.
Introduction The RepRap Project In 2009, Dr. Adrian Bowyer and his students published “RepRap – The Replicating Rapid Prototyper.” which detailed an Open Source, unpatended, FDM 3D Printer with plans made freely available. By no coincidence, Scott Crump’s patent on FDM expired in 2009. The manuscript is an interesting read, especially some of the backing… Read more: Key Events in Open-Source Additive Manufacturing
Introduction Additive Manufacturing Before 3D Printers According to Wikipedia – 3D Printing and additive manufacturing (AM) are synonymous (Two words for the same thing). But I contest that point – given the name, additive manufacturing means to create something by adding material. If we stick with that interpretation, the concept of adding materials to make… Read more: Key Events of Closed-Source Additive Manufacturing
This page is just going to serve as a very basic primer as to what 3D Printing is (I’ll use this term interchangeably with Additive Manufacturing, and sometimes abbreviate it as 3DP). Almost every sentence in this page will be extrapolated to an entire lecture later.
3D-Printing has quickly become a ubiquitous means of prototyping and manufacturing. But it is wise to understand what other means of manufacturing are out there in order to understand where 3D-Printing fits in and what makes it so powerful.
I use an Arduino nano paired with a photoresistor to capture light signals from the lava lamp. Those signals create midi packets that my computer uses to generate the audio. In this video I’ll show you all of the software packages that I used to make this happen.
Here’s my first attempt at making an educational short! A quick experiment where I highlight why it’s typically a bad idea to unplug a stepper motor while it’s still powered on.
In this video I get curious about why 2 materials, that are similar in everything but color, react so differently when scanned with a 3D Scanner. I also briefly discuss the way my 3D Scanner works with a video demonstration.
This is a follow up to last week’s video – If you connect inverters inputs to their own outputs – will they get hot? I use a FLIR thermal camera to check the temperatures as well as measure the current for comparison. Finally I take a look at the data sheets to help explain what might be going on.
A simple interface for generating definite integrals that you can solve yourself and test your understanding.

A study tool / game useful for finding links between concepts and terms.
An important piece of 3D Printing technology is the instructions that make them replicate a desired model – those instructions are G-Code!

In this section I discuss some of the common components found in 3D Printers
In this section I go over some of the key mechanical considerations you should take into account when conceiving of a part you’d like to 3D Print.
A discussion of the key points you should consider when creating a piece of open source hardware.
I’m not a FreeCAD Expert – but I realize that OpenSCAD isn’t for everyone. So I’ve put together a collection of some decent FreeCAD resources.
