Zen Diorama – The Breath of the Gong

Zen Diorama – The Breath of the Gong ⛩️🔔

Immerse yourself in a soothing atmosphere with this beautiful diorama inspired by Asian traditions. At the heart of this serene scene stands a stylized torii gate in matte black, from which hangs a small golden gong, ready to resonate with peaceful tones. 🌿✨

🧘♀️ At the base, a miniature zen garden invites you to relax, featuring a central rake and fine grains reminiscent of the sand patterns found in traditional Japanese gardens. The whole composition evokes calm, harmony, and spirituality.

🔔 The gong is hung using a small string, adding a handcrafted and natural touch to the ensemble.

Two versions available:

• Standard model: Perfect as a zen decoration or for creating a small meditation corner without electronics.
• Advanced model: Ideal for makers and home automation enthusiasts!

🛠️ Advanced model – Required components:

• ULN2003: AliExpress 🔗
• ESP32: AliExpress 🔗
• Dupont wires for the connections

Everything is controlled via Home Assistant 🏡📲, so you can trigger the gong remotely from your smart home interface!

🔧 How it works – ESPHome Configuration Example:

Once the ESP32 is configured with ESPHome, the gong can be activated through a virtual button ("Zen ON/OFF") in Home Assistant. When pressed, it triggers the stepper motor to rotate continuously, mimicking the movement of a small striker hitting the gong. Pressing the button again stops the motor and resets its position.

Here is the configuration used:

stepper:
 - platform: uln2003
   id: my_stepper
   pin_a: GPIO27
   pin_b: GPIO26
   pin_c: GPIO25
   pin_d: GPIO33
   max_speed: 250 steps/s
   sleep_when_done: true
   acceleration: inf
   deceleration: inf

button:
 - platform: template
   name: "Zen ON/OFF"
   on_press:
     then:
       - if:
           condition:
             lambda: 'return id(moteur_en_fonction) == false;'
           then:
             - logger.log: "Moteur démarré"
             - globals.set:
                 id: moteur_en_fonction
                 value: 'true'
             - while:
                 condition:
                   lambda: 'return id(moteur_en_fonction);'
                 then:
                   - stepper.report_position:
                       id: my_stepper
                       position: 0
                   - stepper.set_target:
                       id: my_stepper
                       target: 10000
                   - delay: 5s
           else:
             - logger.log: "Moteur arrêté"
             - globals.set:
                 id: moteur_en_fonction
                 value: 'false'
             - stepper.set_target:
                 id: my_stepper
                 target: 0
 

A perfect blend of technology, tranquility, and aesthetic 🎍📡
