The LASK4 system is a device created by Open Muscle that measures the movement and force of all four fingers. The system includes a D'Addario finger training device, custom 3D STL file add-ons, and a custom PCB with electronics for measuring the movement and force. It is also considered a somatosensory device, providing real-time feedback to individuals undergoing hand rehabilitation.
The LASK4 system uses UDP packets via the ESP32-S2 to transmit sensor data to an accompanying computer. The software is currently written in micropython and is both open-source and open-hardware. This allows for greater adaptability and innovation, as other individuals can build upon the design and create even more innovative products in the future.
One of the most exciting things about the LASK4 system is its potential applications beyond hand rehabilitation. The device was designed to label the training data accumulated by theOpen Muscle Band for use in the prosthetics biometric sensor arena. This means that the LASK4 system could potentially be adapted to measure movement and force in other areas of the body, opening up possibilities for new and innovative uses.

Nice project! The way you're measuring finger pressure using a PCB with guitar finger levers is interesting. I used a very similar guitar training device for a somewhat similar project (at https://hackaday.io/project/160690-ergonomic-handheld-mouse-keyboard-alternative). My method with magnets & hall effect sensord doesn't require a custom PCB and custom 3D print, but it requires very delicate solder hacking skills! So your method seems better for mass production than my method 👌
I like your idea of using it to train a Myo muscle prediction algorithm, I hadn't thought about a project using that, so I'll be interested to see how your project goes. I plan on eventually building more gadgets for handicapped people.
