This prototype places the sensors independently, so they can be adjusted to everyone.
It is composed by two 3D printed pieces, one solid with PLA (blue) and another flexible using ninja flex (white). The shape allow us to extend the length of the arm band by adding more pieces in case it's necessary.
This prototype is working well, but now we need to unify this design to make it easy to install and give it an interesting look.
The project that I am working on involves controlling multiple AC appliances from OF. I feel the need to find a better solution other than always splicing and rewriting hot wires because it is dangerous and deadly when I am not being careful. So instead of hot wiring, today, I pulled off the connections from a device that used a rocker switch to turn ON/OFF and changed speed of a motor, and then I wired the connections to an SSR controlled by an Arduino .
Prototyping a backpack to place the electronics.
We think a possibility is to place them on the back to have more space on the arm, because kid arms are small.
Prototype is made with leather and some backpack buckles to adjust different sizes.
This research shows different shapes for spikes that we can sew to the fabric to cover the arm band with the sensors and the electronics. We started to work in a modular way to get the look we are looking for. Also we are working with soft materials to make it safe for kids.
Some materials include leather (grey) and ninja flex printed in our new 3D printer (Ultimaker2).
The final shape allows us to include LEDs inside this spikes with a great look. This material is great spreading the light, you can see the images bellow.
more iterations.
Following the modular line, we are working in joints that can be easily attached and sewn to fabric. 3D printing another piece on PLA (blue) seems like it's working good.
Last version, not printed yet, includes holes to sew the PLA piece to the fabric, see last image bellow.
Tetrahedron kite
We are interested in objects can fly with the wind produced by the fans. Doing research we found these very interesting geometric kites, and we were trying to confection something similar to test in the studio.
Tests were not so successful, wind direction blows away every object, so we need to focus the air flow with more fans.
This is our first approach for an arm wrist that will hold the muscle sensors.
This iteration considers an unique object, but it is difficult to make it adjustable for any size of arm.
We printed one version using PLA on the 3D printer in the studio and another one 3D printed with powder, in a SLA 3D printer.
SLA version looks better but is more fragile.
