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.
