22-DOF Robotic Forearm

Mechanics and Robotics

I’ve designed/programmed robotic arms for precise material handling, designed a novel solution to 5 way solid material separation at a single junction, and I’m beginning to branch into AI vision controlled robots…Let me know if you’d like to donate any RAM to the cause haha!

Robots perform work, and work is expensive. We are talking in excess of $300 per joint for off-the-shelf actuators that will barely do the job we want! We are on a budget, therefore each robot joint requires a custom gearbox tailored to the job, and it must be made from parts that will actually hold up to the future beatings. 

See my 24:1 cycloidal gear reducer design, 3D print files, bill-of-materials, assembly guide, and tips for designing your own HERE.

Manufacturing and 3D Design

Developed custom circuit boards tailored for automation controls, high-end user interface/experience, sensor integration, and solar compatibility.

Design for manufacturing of 2-4 layer printed circuit boards, enclosures, mechanical parts, and rotating equipment using OnShape, KiCad, and Blender.

You’ve never seen a chicken feeder quite like the one I’ve built.

 

Check out the story behind THIS FULLY AUTOMATIC battery powered grain dispenser fit for the most luxurious coops. ALL structural components are 3D-printed using food safe AND weather resistant materials. No need for injection molding.

You can purchase a unit in the store HERE if, like me, you appreciate Saturday mornings and weekend’s away. I’ve had one running in my coop non-stop for just over 6-months without any issues or time-loss!

Available in 87 color options.

Flow – Custom Python Engineering Studio

Chemistry and Cosmetic Engineering

Over the past 12 years, I have managed drilling fluids operations for a total of 34,560 hours and built roughly 215,000 bbl of drilling fluid. I  enjoy working the mud and I’m pretty good at it – hands tied, eyes closed. One neat thing about drilling fluids, is that most of the constituents in the mud are also found in other industries – doing very similar jobs.  Enter Segway.

Sometime shortly after my daughter, Zoe, was born – we began experimenting with custom skincare and “safe” alternatives to big-brand bathroom products. Long story short the mud lab conceded spaced to the “cosmetic formulary”.

Check out all of my research backed formulas for skincare such as “CryoFrese” PolyGel –  a crystal clear Biofreeze Dupe –which I spent literal weeks dialing in. My wife spent a lot of time with the stretch mark belly serum, and everyone loves Dad’s Luxury Leather

A mechanical laboratory setup featuring a robotic arm and several mechanical components, including precision instruments and metallic structures. The setup appears to be for industrial automation or testing purposes, with a clean and organized environment.
