Weekends have plenty of time.

But any good side hack will just make the time for itself. It's that stuff you can't not do so you stay up slightly late and will be slightly more tired at work but hey, so what, you'll feel so good about it that you can't wait till the work day is over and you can continue again. Then it'll fade away and you'll get more interested in work again until one night you figure out where you left with the side project and hey, there you go again.

Personally, I've never been in such a good job that I would always have interesting things to do. So, I've observed that my home-hacking is strictly proportional to the amount of boring stuff at work. I need my dose of programming and if I can't get it at work, I'll get it at home. This kind of takes care of side projects on its own.
