我該怎麼為自己的簡歷增加一些關於CS的項目經歷？

我是EE轉CS。也在努力學習計算機各方面的知識。問題是，我該怎麼給自己的簡歷增加一些項目經歷。我仔細想了下，就算研究生畢業，我所涉及的，也只是學校的編程作業而已，畢竟不是大型項目經歷，簡歷上寫上去也沒用。然後學校實驗室我又進不了。這種情況下，我該用什麼辦法增加此類項目經歷。有人說用github，但是怎麼用，而且是否具有價值，求給建議。

• Any app on your phone / computer that you think could be done slightly better (or better for your purpose).
• A to-do list that syncs with Google Spreadsheets and Evernote (using their APIs)
• An "idea tracker" mobile app to let you very quickly jot down a startup idea and share the list -- or partial list -- with a friend. Syncing with Google Spreadsheets is key.
• A merged registry that creates a merged view of multiple registries. There are many people doing unified [baby / wedding] registries, but they have a major weakness in that they dont show if someone has purchased an item. This would allow someone to create many registries with just one view / link to give out to people.
• A chat widget that allows "branching" of conversations. You know how youll be in the middle of a conversation with someone and then another topic would come up? What if you could branch that part out to a new conversation?
• Chrome extension to overlay Yelp reviews on OpenTable &<--- do this. pretty please? I want this.
• "Forum on the Fly" -- be able to create a very quick forum on the fly by just sending a link, supporting conversation threading and other things.
• Online polls that dont suck / get covered with ads. Think Doodle for polls.
• Social book recommender -- use Amazon receipts in email (this can be done -- TripIt is able to scan gmail) or screen scrape Amazon past purchases to know what youve previously purchased. Then let you see what books have been most purchased by your friends. SO many people I know want this.
