There are multiple ways to setup the STM32 UART for data reception, including polling, interrupts and using DMA. Polling is simple, you just keep checking the UART for data. However, this is a “blocking” function and ties-up the CPU from doing anything else. Using interrupts to check for data reception is a step-up from polling, […]
In my continued work with inertial sensors, specifically IMU’s for use in autonomous navigation systems, the latest sensor I’ve been using is the BMI088 from Bosch. It’s well regarded for it’s ability to handle vibrations and is supposed to be well suited for robotics and drones. Onboard is a 3-axis accelerometer and 3-axis gyro. While […]
Building a modified LOC IV kit for the goal of Level 1 certification. I’ll build this with the intent of flying conservatively, including ejection deployment of the chute. The fins on this rocket have been an area of conern for many others, so I’m also going to swap these out with my own laser-cut fins. […]
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 – […]
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 […]
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!
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, […]
