DIY e-flashcards for language practice

Recently I started learning Mandarin Chinese, and I wanted to make an e-flashcard device for my key-chain. It is way easier to study language instead of using the traditional language flashcards, and you can update the words as you study them.

Currently it works fine for Chinese and also for Japanese. But it can work for other languages if you just the defined font and you can study your target language on the go.
