Content 4/4

i just search counter pcb use 4026 found it redraw it. if you able find classic dual seven segmen CA then try build this epic stuff.  i found the original layout.. but poor quality i tracked and modified the trackline for easier and make double layer. because i hate skinny line under 0.8mm placed jumper on top layer. add some texts. go ahead order it click bellow button only 5 USD you can choose any color. blue or red is good, yellow if you wanna transparant fiber material. hate green too mainstream. dislike white or black color cause track invisible against open hardware spirit.
