Useful techy tools for people that work with computers

I've been a computer technician for nearly 15 years and have found that many tasks I need to do involve using the same online tools again and again.
To make things easier I decided to put this little site together to get all the techy tools in one place that would be simple to use on either my mobile when I'm out and about or on my PC when in the office.
Since you're reading this, I hope you get some use out of this site, I'm adding and sharing more techy tools as and when I require them.
