This week, I helped finalize several key aspects of our project. After researching LCD options, I identified models with integrated ESP32 (IC) that perfectly suit our needs and offer enhanced functionality. I contributed to developing the narrative for our project proposals and conducted comprehensive research on required components. We have decided to order the LCDs before the actual blocks and prototype with cardboard or similar so that we can determine the final dimensions after everything is put together. I made a trip to techspark to ask about the possibility of laser cutting slots in our pre-made acrylic blocks. I asked about the possibility of drilling too for more complex areas. We devised a plan to be able to do this without too much drilling. I also submitted a borrow request for the Raspberry Pi 5 and picked it up from the receiving office.
Additionally, I explored the possibility of implementing a rechargeable circuit system. The concept involved using a power path IC with a LiPo battery for power management, where the blocks would charge when connected to the grid and switch to battery power when disconnected, ensuring uninterrupted power supply. However, I ultimately decided against this approach as of right now due to the complexity of the circuitry and the time it would take to prototyping and testing. Given our timeline constraints and the need for reliable power delivery, I believe that sticking with a known, absolute power supply solution with the 9V batteries would be best and so I found all the necessary components to make this happen.
I am on schedule with all of my tasks. Next week I hope to finish selecting the LCD, order all of our preliminary parts, start a PCB (if we decide this is still necessary as this will depend on what LCD + MCU on the block we are getting), and finish the CAD of the blocks and grid maybe even create a mock model out of cardboard for our blocks and use an LCD I already have to get the rows working.
