Hi Guys,
Today, like the other day, I searched Google for Siliconchip Tachometer and copied the link into Notepad. It is exactly the same link as MP posted. Clicking on my Google link allowed me to see the entire project.
Then I tried clicking on MP's link again and it also allowed me to see the entire project, but the other day it showed only the 1st page and a request for payment to see the remainder.
I don't know what is going on with "cookies" or somethin'. ???
On many other Silicon Chip projects when I posted a link from Google, clicking on it didn't work. But clicking on the link inside Google works every time. ;D
