The idea of this project was born spontaneously - I wanted to do something unusual with programmable LEDs, so that it would be spectacular. I was inspired by large-scale art installations, but I could not stand soldering so many LEDs)
Last year I worked a little with smart textiles and decided to try to make a piece of clothing with LEDs. I wanted to do something similar to Cyberpunk 2077, but I didn’t find the right clothes and chose a strange warm hoodie with color triangles.
I bought 3 meters of WS2812, 60 LED/m strip and cut it into pieces for stripes on the arms and triangles on the chest. I soldered the cables and connectors for all parts and sewed it to the hoodie with a regular black thread. The design had a lot of weak points, because I connected some of them using connectors, but I wanted to try to make a few more projects with these LEDs, so I tried not to fix it too much) And in general, it was not clear whether it would work out at all and how it would all work out look like when we attach the ESP32 (powered by power bank) and the LEDs light up. But it turned out to be quite a show!
At the next stage, Dmytro Dziuba joined me to help program the LED patterns and set up the control logic with the help of muscles. We used a uMyo EMG sensor with dry electrodes to receive EMG signals. We made the LED stripes on the sleeves red, and the clenching of the fist sent out white pulses - the more of them the stronger was muscle effort applied. It looked very cool!
But the selected pattern for the triangles was not so noticeable on the video (it's an acceleration/deceleration of the color change), so we'll do something more interesting next time.
In the meantime, look what happened!
In the first version, muscle control was not sufficiently disclosed, so we made a second attempt. We have added switching between rainbow and sparkling modes by using orientation. For both modes muscle effort controls light intensity, and lowering and raising the arm gives rainbow colors / sparkling color respectively. The result can be seen here:
