No, transistors maybe activate? - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for film; is film needed? Notes: Could make the hole in the digital realm, or perhaps an external module, with the Program with a precision give to the author/donor to decide if having.
