Geek out on this week's picks!
Have Fun! Learn Something!

Well, it's that time again! Time to take a break from your hectic week and settle into some good reading, just in time for the weekend. Too busy right now? No worries, it's all about YOU. We give YOU free stuff and YOU read it when you want. Sounds like a good relationship to me. As always, feel free to share any of this with your like-minded friends, post on Facebook, share with your school, robot club, or whatever your thing is.

 

That's it, enjoy!
