I bought a standing desk but kept sitting, so I invented a device that BEEPS if I sit too long. (Device + Soft + 3D)

How It Works: A User’s Tale
- You're sitting... comfortably.
- You're still sitting... and getting way too cozy.
- You hear a soft "beep beep"... just a gentle nudge.
- You ignore it... it’s just a beep, right?
- 40 seconds later... BEEP BEEP BEEP! Every 3 seconds! 🔊
- You surrender... reluctantly raise your desk, stand up, and bask in the sweet sound of silence.
- 1 minute later... you’re tired already? Seriously?
- You sit back down... but wait…
- BEEP BEEP BEEP... Time to stand up again, buddy! 14 more minutes, you can do it! 💪
🛠 Hardware
Keeping it simple and straightforward, here’s what you’ll need:
- Raspberry Pi Zero (with Raspbian and charging cable)
- HC-SR04 Ultrasonic Sensor: Measures the distance from desk to floor.
- Important: Modify it with resistors to work with 3.3V. https://www.instructables.com/Modify-Ultrasonic-Sensors-for-3-Volts-Logic-prepar - Active Buzzer: The source of your new productivity (and maybe a bit of frustration).
- Buy one with PCB so you can easily mount into the case, the dimension of pcb: 28.5mm x 13mm (around, I've measured it myself)
- Resistors: 1x 2.7k or 2.2k and 1x 4.7k
💻 Software
