Say hello to Xronos Mega
There’s something that I’ve been working on besides Xronos Alarm Clock for the past 6 months. A little story behind it goes like this. I don’t have any wall clocks, so I had a store bought alarm clock (Emerson?) with very large digits (biggest I could find) to serve as a time piece by the TV. Just about when I was getting Xronos V1.0 to see the light that “TV” clock died. And so I started to outline a wall clock that will be really big, with tons of features, remote control, and huge LED matrix display. Thus Xronos Mega Clock was born 🙂 In the end I settled on four 24×16 single color LED matrix displays made by Sure Electronics. Originally I wanted to use same display as in Xronos Alarm Clock (32×16 bicolor): 2 on top would give me 64×16 space for clock digits and then on the bottom I wanted to have a single 8 height row for the scrolling messages that would display date, temperature, etc. Then I realized it’s going to be huge pain in the butt to drive different arrays from ATMega chip, so I settled on four 24×16 displays.
