In the prophecy of Chavakuk (Habakkuk) Chapter 2 verse 11, it is written:
"For a stone shall cry from the wall, and a chip shall answer it from a beam."
This prophecy depicts the state of physical matter during the time of redemption, as also prophesied by Isaiah in Chapter 40 verse 5:
"And the glory of the Lord shall be revealed, and all flesh together shall see that the mouth of the Lord spoke."
As explained in Chabad Legacy, these prophecies indicate that the revelation of the Almighty will be revealed in both the earth and the flesh. The arrival of the Messiah and the revelation of the reality of the Almighty is the purpose and focus of this time.
Inspired by these verses, I created the "A stone from a wall that calls out" representation. I used a hollow artificial rock from Amazon (My focus was not Stone crafting) as the main material and replaced the 10W speaker with a smaller Adafruit 3W speaker connected to a Seeed Studio XIAO ESP32C3 processor and a DFRobot DFPlayer mini audio controller. The Amazon Ring bell detects when I approach the front door, and the HomeAssistant smart home system triggers via MQTT the play of the verse "For a stone shall cry out from the wall..." only during the hours between 8am and 8pm, excluding Saturdays and holidays.
This representation makes me feel as if I am living in redemption, even for just a moment. May we all soon attain true and complete redemption in our lifetimes.Demo

As previously mentioned, my focus was on the electronics and software aspect of the project. For this reason, I purchased a premade stone from Amazon (*). The only challenge was that the stone came with a 10W speaker, which was too powerful and not suitable for the project.
Instead, I used an Adafruit 3W speaker (*) which had a smaller diameter. To accommodate this, I designed a 3mm MDF adapter (**).

** See DXF file of the design in the components section above.
There's not much to say here. It's quite straightforward. I simply ensure that the automation does not run late at night or during holidays. The integration of the Jewish calendar is particularly helpful for this purpose. The front door motion sensor is part of the Amazon ring integration.
Currently, I am using a simple USB battery pack for power. However, I have a small solar panel and lithium battery set equipped with a 3.x to 5V buck converter that I plan to integrate into the project in the future. Something like this.Final Thoughts
One might question the combination of spirituality and technology, but that's simply who I am. I am eager to connect, share, and discuss with others who share similar perspectives.
