The DIY-Noko Monster, lovely and naughty, ready to build on your own. And everyone is invited to contribute. Noko is for everyone. What's new? See the newsblog.

Noko is a multifunctional monster with an ATmega328 microcontroller on an Arduino Nano, display, clock, radio, mp3 player, four buttons as user interface, battery, voice set and tons of gimmicks, packed in a cuddly monster suit - sturdy, lovely and sometimes a bit mean and annoying. Just the way you want him to be. He, she or it - this is your decision and only depends on the voice set. In this repository Noko is a lad, a real bloke! A buddy for life and a companion by day and night. All he needs is a little power every now and then.

Noko stands for Nora and niko's monster.

Notes for non-German Noko makers

There are a German and an English version. Right now, the building wiki, the voice set, the manual and the optional EEPROM text files are in German. I'll try to translate the wiki and the manual one day. Until then, feel free to ask me for translation, if you need help. Contribute! I need an English voice set and English text files. In addition, any other language is welcome, Noko is to be cosmopolitan!

Prerequisites

Noko needs Arduino IDE 1.6.6 - 1.8.2 Copy the folder Noko/V10/src/[language]/Noko/ into your sketch folder. When using 1.6.10 or newer with AVR core 1.6.12 or newer, everything will compile out-of-the-box. With 1.6.9 or lower, Noko.ino won't compile, the sketch size is too large.

Option 1: Install newest IDE and relax.
Option 2: If you are using IDE 1.6.9 or lower, you need to install Optiboot onto your Nano.
Option 3: Take one of the precompiled hex-files and follow the instructions in how to compile.

In any case, Optiboot is strongly recommended.
