Crimpdeq
Meet Crimpdeq, a portable digital force sensor for climbers, coaches, and therapists to measure and train finger strength, pulling power, and endurance.
- Open-source firmware written in Rust.
- Open-source PCB and 3D printable case design.
- Bluetooth Low Energy communication.
- Works with the Tindeq Progressor and Frez apps on iOS and Android.
⚠️ Note: If you want a Crimpdeq but don't have the materials or skills to build your own, feel free to email me at sergio.gasquez@gmail.com and we can discuss other options.
Crimpdeq Book
The book includes everything you need to build and use your own Crimpdeq. It covers assembly, calibration, firmware, charging, and PCB details.
Crimpdeq App
The Crimpdeq App lets you connect to, test, and calibrate your Crimpdeq. It is not intended for training. For training sessions, use the Tindeq Progressor or Frez apps.
See the Calibration section in the Book. The app is available on Windows, macOS, Linux, Android, and the web.
Crimpdeq Platform
The Crimpdeq Platform turns your Crimpdeq into an isometric finger dynamometer. It offers 25, 20, 15, and 10 mm edges, level or unlevel for either hand, an adjustable palm rest, and a phone stand. It is printed entirely in plastic, no extra hardware.
The Platform Book covers the design requirements, printing, and assembly. Ready-to-print STL files and a Bambu Studio project are attached to each release.
Crimpdeq Grips
Crimpdeq Grips are 3D-printed grips for isolated finger training, where each finger rests on its own roller. Photon targets the deep flexor (FDP) in a claw grip, and Spark targets the superficial flexor (FDS) over larger rollers. Every part prints in plastic, pins included; the only extra is a cord.
The Grips Book covers fitting, printing, and assembly. To fit the grips to your hand, measure a photo of it and download the STLs.
