Boeing 502-10C Project

It’s been nearly 10 years since I last owned a turbine engine, so I’m quite excited to have taken ownership of this Boeing 502-10C engine. I shall now embark on another adventure of getting a Boeing 502 up and running. Let the fun begin!

Coolant Flush: Chevy Silverado 1500 – 2005 5.3

  My new farm-fresh 2005 Chevy Silverado has got 130k miles and is in need of some coolant system TLC. I decided to go ahead and do a coolant flush. After some online reading, I found that about 2 gallons of fluid is recovered after draining (which then also needs to be replenished). This formed […]

4’x8′ CNC Plasma Table – Design

We’re working on a new CNC machine, a 4’x8′ CNC plasma table. This post is more for our own personal use while we piece together our design, but it’s also here for anyone else to use as well. It will be updated as the project progresses.   General research and information   Drive: Rack and […]

Arduino And Crystalfontz CFA835 Display

I’m fortunate enough to live right down the street from Crystalfontz America (,  a supplier of high-quality LCD, OLED and other types of display modules. It is entirely thanks to their sponsorship of the current engineering project I’m apart of, that I now have the opportunity to work with their CFA835 graphical LED displays with […]

Arduino Reset Function Using Only Software

Here is a simple, clean and proper solution for doing a full Arduino reset via a simple software function. The general solution was found here and was implemented as follows: Include the proper library: #include <avr/wdt.h> Place this within your “Setup” function: MCUSR = 0;  // clear out any flags of prior resets (used for […]

Building A Ring Roller

A project I wanted to do required me to roll some steel rings from round rod of varying thicknesses and diameters. I looked at commercial rolling tools and even the cheapest ones, such as the offerings of Harbor Freight, were $80. But they didn’t have exceptional reviews and they would mar 1/4″ rod, something that […]

Schlieren Flow Visualization

A really neat technique for visualizing the flow of fluids is called Schlieren flow visualization (pronounced: sh-lear-in). By using either special mirrors or lenses, the density gradients of a fluid can be seen. Examples would be the heat rising from a candle, or the aerodynamics effects of a bullet traveling through the air. This technique […]
