02. Scoping¶

Exploring Requirements¶

試作したいデザインを幾つか検討して絞り込むいつまでに何個試す？？

Wi-Fi capability
Microphone (although unsure whether to embed it in my board or make use of a separate external smart speaker)
AI speech recognition (also unsure how best to achieve this)
Long battery life / efficient power consumption
Easy to sync with Google docs (via API?)
As low cost as possible
What range of CPU/memory is adequate for smooth voice recording and speech keyword recognition?
How would a low power consumption of 15µA translate to battery life?
What are the differences between different connectivity options such as Bluetooth 4 and 5, wi-fi 4 and 5? …etc etc. Hopefully I will have more clarity in a few weeks!

Bottle Placement Recognition: Awareness of when, where, which spice bottle(s) were placed. Ideally at least about 10 bottles per board (but the more the better!).
Wireless communication: Ability to receive user request data from smart-microphone device, about which item has been requested (possibly Bluetooth?). Also to communicate with the online database (via Wi-fi?).
LED output: Send signals to appropriate LED light(s) at the front of punching board, to signal the location of spice(s)
Debugging feature: A test LED and button, (and some additional useful feature for debugging, if I can think of any useful ones in time)
Scalability: Ability to scale up with minimal effort in terms of communication, power supply, etc.
I am not expecting to need a DAC (which is not on ESP32C3).
Size is not so much of an issue for now, as long as it can fit behind the punching board/rack
