Automated build single developer

I know this may be overkill for a single developer solution (personal project and not yet enterprise software), but I was wondering how to better respond to my needs.

I would be needing to accomplish the following:

• Run integration tests (none UI for the moment) at least daily in order to see if any of my commits breaks the build.
• Build the entire solution daily to see if any of my commits are incomplete and would cause problems when checked out on another folder.
• Be run on my personal computer at least once a day (using another computer to automate the build process is not an option for the moment)

I know that automated build software such as Jenkins are easily capable of doing the previous (even on the same machine as committed?), but I was wondering if lighter solutions are available. Ex: Post-commit actions on the repository?, scripts?, planned tasks etc...

Edit

Forgot to mention that I was using a Windows machine with a c# project running nunit tests. I use visual studio 2012 to compile solution and run tests with nunit. I use tortoise svn and Ank svn as repository browser.

Use Jenkins - no reason not to, considering its reasonably lightweight itself (despite being a java app). Its very self-contained too, backup involves stopping the Jenkins service and copying the installation directory so it's not going to pollute your OS.

Anything else you come up with is going to be too complex (in terms of maintaining a bundle of scripts, scheduled tasks and so on) or just as 'heavyweight'. You might as well save your time and use the tool that fits from the start.
