Yesterday I finished the last final exam of my undergraduate degree. I’ll officially have my BS in Mech. Eng. in a week! 6 years of hard work, lots of fun along the way. Now on to my MS in Aerospace Engineering. I’ve been busy trying to make this thing hit it’s design targets:

Rocketry is just about forcing cylinders in and out of each other

Starting a petition for McMaster to carry basic analog read DAQ hardware (like an NI 6001 or 6002). There’s been 3 times this year where I need a simple DAQ fast and I have to wait a week minimum for delivery, smh.

Not now, s*ftware engineer, I'm writing firmware with my left hand while soldering with the right and controlling CAD with a neural headset to create gears Go to your room and play with your LLM-electron-webslop.js thingy Let The Man do The Job

NASA made Modular Robotic Vehicle that have all wheel steering mechanism like this Mercedes successfully made an electric motor that’s small enough to put in wheel hubs It’s possible to build T-180 from Speed Racer today, just saying

Thank you Robert Goddard for enduring the naysayers and bringing us this wonderful technology that I have made a career out of. The Space age couldn't have happened without you.

A 2.5-second rocket flight that heralded decades of discovery in space! Today marks 100 years since the first successful test of a liquid-fueled rocket. Robert H. Goddard's achievement would have appeared unimpressive by most measures: His rocket flew just 41 feet in the air, landing in a nearby cabbage patch. Liquid-propelled rocketry has been the backbone of spaceflight ever since. 📷 by Esther Goddard on March 16, 1926 (Clark University Archive)
On a snowy March 16, 1926, Dr. Robert H. Goddard rests his hand on the testing frame supporting his liquid fuel rocket at Ward Farm in Auburn, Massachusetts. A wooden door is propped up at an angle next to the frame where Goddard\u2019s assistant, Henry Sachs, later sheltered after lighting the rocket.

This is a view from a hot fire from a new stand with a new motor today. This is the seventh rocket test stand project I’ve worked on in the past 15 months. This one was cool, all remotely controlled oxidizer loading / unloading with solenoid valves. I also got to machine that nozzle + a bunch of other misc parts, and setup a bunch of the sensors. This wraps up my summer internship. They offered me a ft position and I accepted. I’ll keep working on my masters remotely while I develop the next test stand, which will be rated to 25k lbf. Headed back to Utah, our second baby is due in a couple weeks, after that our family will be full time Alabama residents!
