Most IT companies participate in the race to grab people’s wrist. A smart watch becomes the most significant item in a wearable device category. You can easily find this mood in this link, there are tons of smart watches.
But here is a simple way to evaluate smart watch’s future on your own. Make it! With Arduino micro-processor and Android, I made a simple smart watch and named it “Retro Watch“. You can do this too!
Retro Watch is an open source project to let you make a smart watch based on Arduino and Android. This text explains about modules, blueprints, how to install and use the Arduino and the Android source codes step by step.
Updated (2015.01.12) : RetroWatch supports u8glib. Now you can use various kind of OLED(or else) as you want and it consumes less memory(RAM). Instead it’s liitle slow at screen refresh. You can find updated sources at GitHub.
RetroWatch is a simple system that is used a hardware platform called Arduino, which is intended for artists, designers, and hobbyst, and an Android app. The overall structure is in the picture above.
Imagine a very small computer that you can wear on your wrist. Arduino board is a micro-processor and a storage, and there’s only one input method : a button. Bluetooth is to communicate with other devices, and the battery would be necessary for power. I’ll install an Android app for collecting or editing various RSS and system information and for notification on the Android device.
