+# miniDenko - A portable messaging device
+`miniDenko` (Denko = 電光 is from "an electric scoreboard" in Japanese) is a portable messaging device.
+
+<p align="center">
+  <img align="center" width="30%" height="auto" src="./images/md_2_sd.gif">
+</p>
+
+## Features
+- Edit & save your message and show it up instantly.(Sub-second booting)
+  - Also supports Japanese characters thanks to [Arduino-misakiUTF16](https://github.com/Tamakichi/Arduino-misakiUTF16) lib written by [[Tamakichi]](https://github.com/Tamakichi) san.
+- Easily connectable with Phones, Laptops, etc. via WiFi.
+  - Supports `STA`, `AP`, `AP_STA` modes to collaborate with the devices.
+- Made from easily-obtainable parts. (See [#BOM](#BOM))
+- Its [portable and slim shape](./openscad/minidenko-case-body-opaque.stl) fits in your (large) pocket.
+- LED Matrix + esp8266 + MPU6050 + Modern Web framework(Vue.js + Buefy) = A hackable LED messaging platform
+- And as a latest gadget should be, equipped with the **Type-C** charging port.
