this is a DOT MATRIX LED clock, which also includes a 8X2 LCD!

it is built using the PIC16F913 from Microchip, which provides 4K program memory, and runs at 8MHz. there are

256 bytes RAM!

here you see the LCD menu in action. most topics have no effect, but can already be browsed, and binary switches (ON/OFF)

can be set! right now, 2700 program words are used. today i have added time display for the LCD, next thing will be weekday and months scroller-

it can use japanese language! of course, it can also show english days and months, and two time zones at once. the menu is only in english (4K memory are not endless, also english is more easy to abbreviate).
