Watching a documentary, I heard Michio Kaku telling that when he was young, he built a home-made particle accelerator. What I would like to know is if I, myself can do so? And how?

It is not so hard, but it won't be able to generate enough high energetic particles.
The best example for a particle accelerator is a CRT (cathode ray tube), which you can find in every CRT monitor or TV. It can generate around $40\rm\,keV$ electrons. (LHC generates $3.5\rm\,TeV$ protons, thus it is around a hundred million times stronger).
Only a particle accelerator isn't enough, if you want to make experiments with it, you need some analytic/measurements devices also. In the current accelerators, they are nearly so complex and costly as the main accelerating device.
There is also a device capable to be built in home, it is the Farnsworth fusor:
Maybe it is not a particle accelerator in the classical sense, it creates enough strong field to be able to fuse deuterons (although it is doing this with terrible efficiency, around $10^{-8}$). You can see a Farnsworth fusor scematic below:

There is a whole community of home fusors which can be found here.
