I just published my first book. It's called All-In-One Electronics Guide. It's an execellent reference for electronics engineers, technicians, educators and students.

Check out my book's landing page! http://www.ALLinOneElectronicsGuide.com/

I also develop mobile app. Download our FREE Android stock investing app. We appreciate if you'd let your friends know about it too!
