History

At the beginning this project was to buy a led sign to interface with my home automation network. This automation network display information like temperature, wind speed, humidity, etc.  I had bought on EBay a LED Sign but when I received it I got a surprise! There was no serial port to program messages… After a couple of days, I look inside to see how it was built.

Propeller Clock

admin    All projects, Gadjet     AVR, Propeller Clock

History

I got this idea by browsing the web. I found by hazard  Mr. Bob Blick's page who make the first propeller clock.  I began to check how can I build one myself.  Base on AVR AT90S2313 I saw rapidly that my MCU must be clocked very fast to make all the calculations needed to light the leds at the right place.  The speed is at 16Mhz,  4 times faster than Atmel's specifications. It's working without any problems.
