“In this instructable I build a simple wood LED clock, using modern electronics components and traditional wood and metal working techniques. I use a 16x9 LED matrix from Adafruit as a digital clock face, power it with an Arduino nano and use a DS3231 Real Time Clock (RTC) to keep time. I also show how to make the pretty reclaimed wood and aluminum box as the case. All with simple tools (plus small drill press). This is a fairly simple electronics build, I assume basic knowledge of Arduino and an ability to do some simple soldering. “
