This LED clock kit from EBAY uses 6X S8550 transistor to drive each of the small 0.5 inch LED display
need to use bigger digits 1.8 inch require 7.2 Volt DC to glow.
is it possible to connect 7.2 Volt to these transistors and drive the big LED segments ?
Sure I will keep the 5 volt regulator to supply the PIC chip with fixed 5 volt....
If this is possible, do I need to change the 7 resistors(each is 1 Kohm) going to the a-to-g segments ?
