Hello,

First, thanks for responding.

I am interested specifically the "Wifi Flip Clock/Youtube Counter"

  Are you sure? yes | no

Michail Wilson wrote 01/31/2020 at 22:25 • point

have you posted the files (gerbers, source, or anything).   I can't find them in any of your projects.  

  Are you sure? yes | no

sjm4306 wrote 02/03/2020 at 15:43 • point

What projects did you specifically check? For some of my projects they are under the Files section, but I'm still updating the rest of them.

  Are you sure? yes | no
