You have been 'busy' all this while( even if it's a sabbatical). That's important, that is what you need to project to your potential companies on your application.

Create a personal website(if you don't have one) and put up your personal projects that project you in a positive light. Github is also great.

When a company receives a resume, there's no way to quantify and judge what the candidate has done in the past year. Give them something to think about.

I have marked Cybercoders as spam and you should too. They lazily bombard you with irrelevant jobs. There are other tech recruiting firms(Bay Area and LA) that have better reach and more understanding of candidates profiles. LinkedIn is great for networking and reaching out to recruiters and seeking out referrals.

Mark up your sabbatical period on your resume. Write in there "Traveled the world exploring new cultures, worked on personal projects, taught myself new skills to grow forward." Mention a supporting online link in this section. Nothing to hide here IMO

On your website, you can write down experiences you gained in detail, while working on your open source projects, what you learnt. This is a huge plus. Many candidates send in resumes without a proof of their past projects. You already got this, try to work it into an interview call + offer.
