Designing The Improved Prototype
Clevis Pin Design Upgrade
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…
ESP32 S2 Pinout for the wemos esp32-s2 mini
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…
Designing the Open Muscle Band
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 3×3 Grid proof of concept
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…
