We have received both copies of the hardware and tested that they work as expected. Since LED grid is being made, a risk is that while working remotely, it is hard to communicate the exact specs, so that we might have 2 copies of slightly different LED grids. We will minimize the risk by assembling the LED grid together and write test files to ensure that they behave the same way as expected.
Another challenge is that our power supply didn’t arrive on time, so we cannot embed the program yet. We are testing the peripherals from the computer directly. We might need to pay more attention testing these application we wrote once it’s flashed on Jetson Nano.
We decided to change the LED gridding from 2*5 to 3*3. That is, instead of 10 food items, we aim to target 9 items instead. We made the change since it allows clearer gridding while also simplifies the logic for LED light up algorithm.
In general, we do not have any changes to our proposed schedule. This week we worked on the design review presentation and also the report together. At this stage, we are very clear with what we want as a product and how to implement it.
