“This is a clock based project. The title of which embodies the main means of displaying the time.
The “Lumi”, being an abbreviation for Luminous.
Utilising lumious paper in conjunction with UV LED’s to display the time which fades over a period of time between updates.
For a bit of added nostalgia, the numbers are in a dot matrix format.
In addition to luminous paper and UV LED’s the clock uses a Microbit, RTC, Digital Logic, 3D printing and Mechanical parts.
