Click-Clock Board

The Click-Clock Board is a digital 7-segment display clock I developed using KiCad, Verilog, MyHDL, Logisim, Icarus Verilog, GTKWave, Espresso, a solderless breadboard, and a Spartan 6-based FPGA board called Mojo V3.

The first PCB prototype was hand soldered by me using 0.5mm diameter lead-free solder. I am planning to reflow the next board using solder paste for much nicer assembly.
