About this project

CulBox, an Open Source DIY Smart match for Arduino:

Fully assembled first prototype
Fully assembled first prototype

CulBox is a tiny wearable wrist watch made for Arduino makers who are ready to make tons of applications with the easy to use Arduino libraries and samples for this new technology.

The actual main board
The actual main board

The main processor on this watch is a tiny RFDuino ARM Cortex with the built in Bluetooth Low Energy Made by RF Digital Company and named Simblee which is very common and popular and has tons of samples and libraries

Features:

  • 32 bit Arm Cortex processor
  • Built in Bluetooth Low Energy (BLE)
  • 6 axis I2C Gyro + Accelerometer sensor
  • 24bit I2C very accurate digital Altimeter / Air Pressure Sensor
  • SPI Micro-SD card memory
  • SPI 16bit color 1.5" OLED display
  • On-Board Microphone
  • 3 Push buttons
  • Audio output Jack
  • Built in Piezo speaker
  • USB port with FTDI converter
  • Rechargeable LI-ION battery
  • Built in Automatic charger
  • Battery charge Fuel Gauge on I2C Bus
  • Build iPhone and Android apps without Xcode or the Android SDK in Arduino using RFDuino Simblee Arduino Libraries

 Build iPhone and Android apps without Xcode or the Android SDK !

Although the SDKs are available to make Native apps for who have experience with app development, CulBox has this ability that gives you the power of making apps on your iPhone or Android device without knowing anything about app developing and using Android SDK or Xcode!

The Simblee chip we used on this product comes with a multi purpose raw app that you can download it from App Store or Google Play Store for free and then use that app as a user interface only and design your app in your Arduino code. the Simblee app acts like a raw touchscreen display that has libraries like making buttons, drawing lines and circles and etc. so with the CulBox Arduino libraries and the samples, you will be able to easily make your app and connect your watch to your phone and use it for your application.

16bit 1.5" OLED Display:

The display is a very common Arduino OLED 1.5" 16bit color SPI display from Adafruit that has high resolution, good quality and low power consumption. the display is OLED that means all pixels are individual LEDs. that means when the color is black, its absolutely black!. it's supper easy to run the display in Arduino with all samples and libraries.

Built-in BLE and short range Radio:

Simblee chip has a built-in radio module that can be used as a Bluetooth Low Energy or as a short range 2-way radio transceiver .

BLE mode is used for communicating between the Watch and your iPhone or Android Device

The short range radio if for intercommunicating between two or more Hardware or between your Watch and RFDuino products to transfer data or control something with your Watch remotely or Communicate with Other CulBoxes

6Axis Gyro/Accelerometer:

A very sensitive and precise 6D motion sensor is on the board that can be used for applications such as Step Counter, Accellerometer, Gesture Detector and many many other applications. The Accelerometer can measure up to 16g and can be used for measuring the compact or Acceleration

24Bit Air Pressure Sensor / Altimeter:

Supper sensitive digital high resolution air pressure sensor that can measure the air pressure difference with 24bits worth of resolution . that means you can calculate the Altitude from the sea level without GPS and even more accurate than the GPS!

On-Board Piezo Speaker
On-Board Piezo Speaker

There is a Built in Piezo on CulBox Board to be able to make short beep sounds or even play ring melodies. the Piezo is connected to the PWM pin directly so the user have complete access to that. here in this video you can see a melody is playing with CulBox using the Piezo speaker

Built in Microphone:

There is a very tiny microphone on CulBox board which is connected directly to the microcontroller so you can use it to record audio or use the Arduino libraries to detect voice commands such as clapping hands or snapping like the picture below:

Battery and Power:

All of the devices used in this board are super low power and the whole device can last for months in standby mode with the 500ma battery.

There is a smart battery fuel gauge chip used in CulBox to make it easy to monitor the battery charge level all the time even when the device is off.

A built in charger chip can charge the device from the USB port or a wall charger in one hour.
