Hi all,
I need to design a 555 timer with a high period of 1ms and a low period of 4 seconds. I used the site below as reference, but when using the formulas mentioned, I ended up with values which are not possible (either to large of with a negative value).
Can anyone tell me is the design on this site is good? or any reliable site that I can use to solve this?

Thanks in advance.
