Reasoning Today, I will be showing you the DIY PCB etching workflow used in the lab where I am working. In the post last week, I discussed the design considerations for a TB6621FNG motor control board. This post will document how the physical PCB was created. Previously, when I have wanted to produce a PCB, …
Background As part of a to-be-announced project I am working on, I ended up designing a new Toshiba TB6621FNG motor control board which is designed to be compatible with the Raspberry Pi. Before I began this design, the lab I am working in had been using controllers based on the Rohm BD6222HFP chip. This is …
Dissertation Publication Since my dissertation was recently published (see last weeks post), I thought I would post the template I used to create it. Oklahoma State University does not currently offer a default LaTeX template for a dissertation. Instead, they only offer a Word template (gross!). I took it upon myself to make an Okstate …
It is a new year, and my dissertation has finally made it past embargoes to publication. Allow me to present: Development and Applications of Chemical Sensors for the Detection of Atmospheric Carbon Dioxide and Methane. You can view the ProQuest entry here. There is a download link to the full text at the bottom of …
Two weeks ago, I discussed the inspirations for a Greek Philospher mask. Last week, I showed how this mask was built up. This week, my Greek Philosopher mask will be completed with the addition of paint and lacquer. An Aside About Rocks The ‘stone’ surface of the Greek Philosopher mask was painted to look similar …
Last week, I discussed the inspiration and first few layers of my Greek Philosopher mask. This week, I will be showing a bit more of the build process. Building Up The process I used to make my Greek Philosopher mask is very similar to what was used in the Witch mask design. The bulk of …
One of my favorite creations of late has been my Greek Philosopher mask. For the next three posts, I’m going to go over the construction process I used for it. The Madness The inspiration for the design of the Greek Philosopher mask came from three sources. The first source, and perhaps the most subtly influential …
This is a proposal I wrote and submitted to the July 2017 cycle of the NASA NPP program to work on development of SiC logic for a Venusian satellite project.. It was rejected and I went another direction. The SiC logic proposal idea was generally well received. While many of the reviewers comments could have …
I took a lovely picture this summer of a giant robber fly eating a cicada. The picture was taken in Washington county, Oklahoma. I observed the take-down myself while working in the garage. The robber fly ambushed the cicada while it was sitting on an overhanging branch of the nearby hackberry tree. In the above …
I have returned from the dead and am back from hiatus. This brief intermission was due to moving and real-life delays. Please enjoy this entertaining image of my cat carrying his favorite toy as a gesture, re-welcoming you to this blog now that I am back from hiatus.
