The boards have finally arrived and the Gerber files are being uploaded to Github. The diagram is currently being developed but here is a sneak peak of it, plus of the 5.3.0 prototype!!!
We were testing the least expensive option for smooth pistons and the clevis pin + compression spring combo has, by far, outshun the other piston mechanisms. Versions 1, 2, and 3 are being retro fitted with the new clevis pin piston adjustment at his point in time.
It was difficult to find the ESP32 S2 Mini pinout and even the wemos website does not specify what the pins are save for in the datasheet. According to the images The ESP32 S2 mini pinouts show pins 1-18,21,33-40 being accessible via the board.

The design of Open Muscle has gone through a few changes and the latest iteration has taken a more simplistic form. Currently being developed on the RP2040 chip found in a version of the raspberry pi pico by waveshare, the Open Muscle band is utilizing the four ADCs provided by the main chip. Although one… Read More »Designing the Open Muscle Band
The first prototype for the Open Muscle a 3×3 grid of hall effect sensors and their tubes. This array or rather matrix, works well to detect the muscle contraction but the spring tension needs to be adjusted. Thankfully we have moved toward the CELL0 – TUBA design on the current V 1.3 device.
