KINETIQ
Verified files and documentation.
CAD, the parts list, firmware, software and assembly guides, published after the prototype is tested. Parts from about $1,123 for the Lite build, cutting the metal yourself.

A programmable smart gym you can eventually build yourself.
Kinetiq Gym is an open-hardware digital resistance platform in development. Follow the physical build, testing, software, and verified CAD release.
Renders of the engineered design. The first physical prototype is being built now.
What Kinetiq does
A programmable digital-resistance platform, built as open hardware for people who want to train with it, build it, modify it, and program it.
- 01Programmable resistanceA motor and a cable drum stand in for the weight stack, so the load is set in software.
- 02Adjustable cable position and directionIt mounts on a rack upright at the height you want, and the cable exit swivels to follow the pull.
- 03Software-defined training modesEccentric, chain-style and band-style resistance are designed as modes, not attachments.
- 04Customizable hardwareOne bolted aluminum frame, five motor and power builds, two battery sizes, and documented interfaces for your own.
- 05Local, hackable architectureDesigned to run on its own controller and a Raspberry Pi, with no account or cloud service in the loop.
Watch the design in action
One minute. The whole machine.
This animation shows the current engineered design and planned user experience. The next step is proving the architecture in the full physical prototype.
Current build status
What is real today, and what comes next.
- Finalizing
Design and animation
The aluminum build in CAD with five motor and power options, and the 1-minute animation of how the machine is meant to work.
- Done
Printed fit test
Every part printed and fitted against the design, to catch CAD mistakes before any metal is cut.

Aluminum prototype
The machined 6061 frame, bolted together with no welding, with the real battery and BMS. Proves the mechanics, cable routing, force control, safety and assembly.
- After testing
Verified open files, then kits
CAD, parts list, firmware, software, and assembly and safety guides, released together. Kits follow if there is demand.
From the bench
The prototype has started.
The first parts are in: the motor, its clamp coupling and a 12 mm shaft. Next come the aluminum frame, machined in-house, then the drum and the level-wind.
Each stage is posted as it happens, failures and redesigns included. The build list gets the results first.
What you will see next
Why open
Most digital resistance systems are closed appliances. Kinetiq is being built so builders and researchers can inspect the mechanics, modify the hardware, write their own training modes, and build on the platform.
The files will be published once the physical machine has been built, tested and documented, so what you download is something that has actually worked. Until then, the build preview shows the current engineering in detail.
Where this is going
Build it, buy the hard parts, or work together.
Kits and machined parts, if there is demand.
Machined plates, printed parts or complete kits may follow the verified release. Nothing is for sale today.

Kits · planned
The hard parts, made for you.
The laser-cut, tapped and countersunk plates, the machined bearing holders and brackets, and the drum and rack side ready to bolt together: the parts most builders cannot make at home. Printed-part sets and complete machines may follow.
Not for sale yet. Kits open only after the prototype passes load testing, and the waitlist hears first.
Support the project
Help turn the design into tested hardware.
The CNC machine is already in the workshop. Support goes into building, testing and improving the prototype, and into making the machine easier for others to build.
- 01Prototype iterations
Parts, aluminum stock and the revisions that come out of load testing, measurement and real training.
- 02Build support
Clear build instructions and videos, fit coupons, test jigs, and help for the people building their own.
Who is building it
Designed and built by Trent.
I design Kinetiq Gym end to end and build it in my own workshop: the mechanism and the CAD, the machined and printed parts, the electronics, the motor control and the software that ties them together.
The project is shared as it happens, including the parts that don't work the first time.
- Mechanical CAD
- CNC machining
- 3D printing
- Embedded electronics
- Motor control
- Software
- Physical prototyping
Engineering
Building something difficult?
Kinetiq Gym combines mechanical design, CNC machining, additive manufacturing, embedded electronics, motor control, real-time software, and rapid prototyping. I take on a limited number of custom engineering projects where that same stack is useful.
- Motorized fitness or rehab equipment
- Robotics and actuator prototypes
- Cable-driven mechanisms
- Custom motor-control systems
- Prototype hardware that needs CNC, 3D-printed parts and electronics working together
