  Finally, the printing of the cover for the first prototype has been finished. In the meanwhile, all the other electric components like the LiPo and the new display arrived. We have decided to use a TFT screen instead of an OLED as mentioned before. Two main reasons had lead us to this decision:

  • It is a RGB color display and not only monochrome blue or white
  • It has a resolution of 160x80 dpi instead of only 128x64 compared to the OLED

  Even though the power consumption will be higher, we consider the advantages more important. We will now start to wire up the whole prototype for the first test runs and extend the functions of the firmware. Moreover, we are finalizing the PCB-design for the first prototype of the slider to scroll through the screen.

  Hello to everyone who is following this project. These Logs are going to document the development of the Smartglass project. Right now, I am testing the lens and the mirror. Therefore, I use a wooden prototype cover. The distance from the OLED to the lens is the exact focus length of the magnification lens to create a clear image on the screen (picture 1, 2). The wooden prototype is attached to an old 3-D glass to test the created Image (Picture 3). As you can see on picture , it works quite well ( picture 4). Simultaneously, the first tests with the BLE-connection and the smartphone have been completed successful as well. Right now, the design process of the 3D-printed cover and the Eagle design of the PCB for the slider is in full effect.
