It seemed like nearly half of all my interior lights were burned out — the instrument cluster, steering wheel, HVAC controls, door panels… everything had about 50% of the bulbs actually working. Having always been a Ford owner, is this some kind of Chevy thing? The gear selector display (also referred to as the PRND321 […]
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 […]
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 […]
In completing my B.S. in Mechanical Engineering, one of the courses I’ve got to complete is Senior Capstone. In this course you’re given the option of either selecting a project to be apart of, or proposing your own. I had two of my own projects in mind, one being a CNC hydraulic tubing bender. However, […]
Here’s a pretty cool little adjustable power regulator by DROK® I received it today through Amazon. I’m always needing to hunt around my office for a proper power supply to power whatever electronics item I’m playing with at that moment. I’ve got several regulated power supplies, but none of them are adjustable. So this unit […]
I’m fortunate enough to live right down the street from Crystalfontz America (Crystalfontz.com), 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 […]
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 […]
(UPDATED: See my most recent updates towards the bottom) I recently looked into getting a toll-free vanity phone number for a business. Having no clue about it, I did the usual, ask Google. Right away I was presented with a ton of companies who offer toll-free services as well as sites offering “reviews” on the […]
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 […]
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 […]
