Robotic Tortoise – Part 2

It’s time to go BIG! The robotic tortoise is getting super-sized and will use full-size servos instead of the micro servos. It will be getting a “head” with an ultrasonic sensor for depth perception. This should be a fun one! I’ll continue to update this post as this phase of the project progresses. 1/29/2023 – […]

Robotic Tortoise

I’m always looking for another project to build. My most recent project was initialized by my son, who had an idea to build a robotic tortoise. Sounds fun! Though with no solid idea yet how I’d get a four legged creature to walk, I jumped in. Step 1: Leg design Fundamental to a walking turtle […]

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 […]
