IoT Train Display (2023)

I bought the real indicator of Tsukuba Express from Shosen Book Store and analyzed it. Actually it was a bit complicated fo hobby purpose because there are many real components for the real train operation.

So I build my own custom printed circuit board with ESP32 Dev board. The PCB has same dimension and can be installed into the original case cleanly. ESP32 can be connected to Wi-Fi easily, so you can control this from PC over RESTful API.

Egyptian 1906 (2022)

Egyptian 1906 is a typeface based on "Egyptian" by William M Healey, which appeared in "Henderson's sign painter" (published 1906, Library of Congress collection). As the original design contains only uppercase and lowercase letters of the Latin alphabet, I designed the matching numerals and punctuation to create the font data.
