Ruby red surface mount charlieplexed LED clock in wooden frame
The clock above is in a grey washed chunky wooden frame. I currently have four of these hand-built clocks with ruby red LEDs completed for immediate sale.
These clocks are hard to photograph due to the rapidly flashing LEDs, but the video below will show you how it operates. Lights stream out from the minutes position and disappear into the hour position while a seconds LED marches round. In addition there is a selectable mode where only the hours minutes and seconds are displayed without the scrolling LEDs. There is a night mode where the clock automatically switches between scrolling during the day and no scrolling between the hours of 10pm and 8am.
