About the DC-34-Countdown-To-Singularity PCB

DC-34-Countdown-To-Singularity is an open source AVR/Arduino PCB design by eggsactly, published on GitHub. It is a 2-layer board measuring 145.3 × 221.5 mm, with 54 components from 24 distinct parts.

Its main chip is the ATmega328P-P, from the AVR/Arduino family. Other key parts include the LM7805_TO220, LM317_TO-220, PCF8523T and CC56-12CGKWA. By type, the board carries 16 resistors, 13 capacitors, 10 connectors, 6 ICs, 3 switches and 3 diodes.

It belongs with the wearables, displays & leds and usb & debug tools designs in this gallery.

From the project

DEFCON Badge to Countdown to the technological singularity

Please note: please run kicad from the same directory as the .kicad_pro file is stored because the fp-lib-table and sym-lib-table use relative paths so that this project is portable between computers.

When using the programmer, first program the fuses to match the Arduino fuses.

Then you can open the Arduino IDE and flash the bootloader with the following commands
