Final Prototype

DeclerckRobbe : January 14, 2016 18:52 : Case11_2015

TYQO a showcase model that implements the new technology that Quad ind. has researched to thermoform electronics. Combining engraving, Thermoforming and capacitive sensors to create a unique user experience. Being waterproof and dustproof makes it an interesting technology for industrial machinery, medical industries and free forms.

Electronics: final update

tacker : January 12, 2016 13:52 : Case11_2015

Electronic schematic:

The Raspberry Pi is powered by 230V AC. When plugging in and booting the RPi, the program automatically calibrates & is ready to be used. Simply plug in your speakers into the auxiliary jack.

The Raspberry Pi communicates with the display via SPI & communicates with the capacitive touch sensor via I2C.

To achieve tactile feedback, a vibration motor was added. After touching the buttons or the slider it vibrates for a short amount of time. Visual feedback is obviously caused by the TFT display and two blue LEDs behind the surface.

8 pieces of copper tape are attached on the back side of the slider, making circular sliding movement possible. 2 of them are used for the general buttons. They are connected to the MPR121 controller with jumper wires.

Engraving PET

DeclerckRobbe : January 10, 2016 14:55 : Case11_2015

The material we used for engraving was not Plexi glass but PET.

Using the positioning based on the previous post an engraving file is made.
Texture laser file

Configurations for engraving:

First Test: Power 100% Speed 100%
note:Not deep enough engraved

Second Test: Power 100% Speed 50%

Applying texture on our prototype will enhance the tactile feedback when used. To do so we need to know where to engrave this on the plastic sheet. Deformation will occure when the sheet is thermoformed. Creating a consistent workflow makes it possible to reproduce the same result out of the thermoform process.
