This repo contains the source files for my self made binary clock. It uses a TI BQ32000 real-time clock chip for time keeping, a TI TLC5928 LED driver for the LEDs and an Atmel AtTiny24A microcontroller to control it.
The pcb/ folder contains the schemtaic and board layout (made with EAGLE). The firmware and source code for the Atmel microcontroller can be found in the code/ folder.
The v1 board layout contains some errors. The footprint for the LDO is wrong and connects +3V3 to GND. Also I forgot to add a decoupling capacitor for the RTC. You can work around this by isolating the big tab of the LDO from GND, the RTC functions without decoupling. Version 2 fixes those errors.
