The Droidalyzer is an open source, Bluetooth alcohol detector accessory for Android Phones. After pairing the device to your phone using Bluetooth, breathe into the device's alcohol sensor and then check your alcohol level from your phone.

In addition, the Droidalyzer doubles as a general purpose board for Android hardware accessory development (details below).

Note: The Droidalyzer is a novelty device, it is NOT calibrated to be a professional Breathalyzer and/or medical device and is for entertainment use only.

After each alcohol reading, you’re prompted with various options such as calling a preset designated driver, calling a taxi, finding nearby friends and places (using Facebook integration), and even a random drunk dial option if you’re feeling adventurous. It does not output a blood alcohol content (BAC) reading and instead plays different audio responses relative to alcohol levels with four character voices to choose from. The voices were done by a professional voice actor.

In addition to the alcohol detector function, the Droidalyzer is also a full Android hardware development kit based on the open source IOIO platform. IOIO (pronounced "yo-yo") is a bridge between Android devices and external hardware such as sensors and servos. IOIO enables you to add the computational power, touch display, connectivity, and built-in sensors (camera, GPS, accelerometer) of Android to your projects. IOIO can connect to Android devices over both USB and Bluetooth. Here’s a few IOIO projects which will give you an idea of what you can do with IOIO. 

Unlike Arduino methods of interfacing with Android, IOIO differs in that the firmware is taken care of for you. You have full control of the IOIO pins from within your Android application code using the supplied IOIO Java-based libraries; no additional Arduino sketches are required!  This significantly simplifies the process, allowing you to focus solely on your Android application code.  In addition to basic digital input/output and analog input, the IOIO library also handles PWM, I2C, SPI, and UART control. The firmware is easily upgradeable using the IOIO Manager app from your Android phone.

Droidalyzer is a special edition version of the IOIO board with the added features of an on-board LiPO charger, LiPO battery, header pins, included Bluetooth dongle, and mini USB board power/charging port, all mounted in a laser cut, mint tin package. Chances are your Android device is compatible with IOIO but we cannot be absolutely certain as each Android device manufacturer can modify the Android build.  The following devices have been verified to be compatible with IOIO.

IOIO has an active community of users who can be found on the IOIO users  forum.  IOIO is 100% open-source hardware and software, with permissive royalty-free license terms.

An initial prototype manufacturing run of the Droidalyzer has been completed. If funded, we'll initiate another manufacturing run. More info at http://droidalyzer.com
