PicoWake (Tomat'O-Clock) 🍅

Printables Link : Here

Meet Tomat'O-Clock, a smart, connected, tomato-shaped alarm clock!

This repository contains the source code and documentation for the PicoWake project. Built around a Raspberry Pi Pico 2 W and a touch screen, this project provides a fully configurable alarm clock with a Web UI, WiFi setup portal, and NTP time synchronization.

The physical build features a capacitive touch sensor for dismissing alarms and a mechanical keyboard switch hidden in the tomato's stem acting as the "Snooze" button.

Features

• Captive WiFi Portal: Easy network setup on first boot.
• NTP Time Sync: Keeps accurate time over the internet.
• Local Web UI: Set multiple alarms, adjust volume, and manage days directly from your browser.
• Custom Hardware Controls: Capacitive touch to dismiss, mechanical switch to snooze.

Setup & Flashing

The source code is written using the Arduino framework via PlatformIO.

Prerequisites

• VSCode with the PlatformIO extension installed.
• Git

Building and Flashing

Method 1 : Custom Build

1. Clone this repository:

   git clone https://github.com/FallMarsisus/PicoWake.git

2. Open the PicoWake project folder in VSCode. PlatformIO will automatically initialize the environment and download dependencies.
3. Plug your Raspberry Pi Pico 2 W into your computer via USB.
4. Click the "Upload" arrow in the PlatformIO bottom toolbar to compile and flash the firmware.
5. Once flashed, the Pico will restart. On the first boot, it will create a temporary WiFi Access Point. Connect to it with your phone or computer to configure your local WiFi credentials.

Method 2 : Use prebuilt binary

You can find pre-built binaries in the releases tab.

Pinout & Wiring

The Pico is designed to be embedded directly into the back of the Waveshare screen. Solder the peripherals directly to the Pico's pins or the screen's exposed pads.

Component	Pico Pin	Notes
TTP223 Touch Sensor (Dismiss)	GP0	Signal pin
Keyboard Switch (Snooze)	GP1, GND	Code uses internal INPUT_PULLUP
Passive Buzzer	GP14	Positive/Signal pin
USB-C Port	VBUS, GND	Power delivery

Hardware & Bill of Materials (BOM)

(Note: For 3D printing files and physical assembly guides, please refer to the project's MakerWorld/Printables page).

• Microcontroller: Raspberry Pi Pico 2 W (A classic Pico W should also work).
• Display: Waveshare Pico ResTouch LCD 2.8". The Pico plugs directly into its back.
• Touch Sensor: TTP223 Capacitive Touch Module.
• Snooze Button: Any mechanical keyboard switch.
• Sound: Standard passive buzzer.
• Power: 4-pin Type-C USB breakout board.
• Hardware (Optional): M3 threaded inserts and M3 screws (for the backplate).
• Miscellaneous: Flexible wires, soldering iron, and glue.

Physical Assembly

1. Prepare the Screen: Plug the Pico 2 W into the back of the Waveshare screen.
2. Solder Components: Cut wires to generous lengths and solder the touch sensor, buzzer, and USB-C port to the Pico.
3. Mount the USB-C Port: Secure it at the back of the shell, aligned with the backplate.
4. Mount the Stem (Snooze) ⚠️: Route the wires through the top hole of the shell before soldering them to the keyboard switch. Once soldered, click the switch into its housing.
5. Hide Touch Sensor: Mount the TTP223 sensor inside the shell, behind the front face.
6. Close Up: You can leave the back open for easy access or seal it using the backplate, M3 inserts, and screws.
