FabLab Clock

FabLab doesn't have a clock (actually, somebody brought an alarm clock but it's hard to read from far away). So I wanted to make a clock for FabLab 'cause time is important and we, makers, lose track of time all the time.


FabLab Clock v001


Clock project using a 32x32 RGB LED Panel for Pasadena City College's FabLab.

I got a 32x32 LED panel that is quite big, not as big as I wanted though (I wanted a gigantic one  hehe) but it'll have to do for now.


As you can see from the picture, the design I have so far is pretty basic. The time is displayed in the center, and the circle around it just an animation for decoration. The circle spins once per second changing colors every second. You'll notice there's a sheet of paper on top. That's for diffusing the LED's since it's quite bright.


I'm using a 32x32 RGB LED panel with a Teensy 3.1 and an RTC module to keep track of time. The Teensy 3.1 has RTC features, but I'm not using them at the moment. I'm using an external RTC clock breakout board. The RTC modules uses I2C to communicate with the Teensy. Unfortunately, my board didn't have pull-up resistors, so I had to add them using a breadboard.
