Free ebook of the day - A Technique for Getting Ideas

A Technique for Getting Ideas

So what this book is about, I hope the below quote from Author, James Wong Young, would get the job done.

"So with the art of producing ideas. What is most valuable to know is not where to look for a particular idea, but how to train the mind in the method by which ideas are produced; and how to grasp the principles which are the source of all ideas."

Retro 3D Snake Game in 8x8x8 cube

Just stumble upon a cool video from a 3D Snake Game done with a 8x8x8 led cube done with Arduino.



Fritz provides free application (wiring diagram) for you to document your next prototype

Prototyping is fun but what if you have forgotten the wiring that you had built long time ago.  So what not document it for record keeping.

A friend of mine points me to this website, Fritzing



Now I can use this free Fritzing app to document my wiring, happy Fritzing...

My 2nd Arduino Project - Interactive Traffic Light with a button




This project is about showing how button would change the state of the lights to make the cars stop and the pedestrian to cross safely.

Initially the car green light and pedestrian red light are on.  Once I pressed the green button, car green light will turn to yellow and red, then pedestrian red light will turn to green and so.

The video recorded an interactive traffic light demonstrated built by 5 LEDs and an Arduino UNO.

BTW, below is the book that I am currently reading.  It's very easy to follow that I highly recommend this book for those who just start to learn Arduino.

What if your websites are not so "Mobile Friendly"?  Lots of bounce back, short duration of visits.  In terms of SEO, it could be a big deal.  Why?

Because Search Giant Google had just changed its Searching Algorithm, so Mobile Friendly would affect the ranking significantly.

To test out your websites Mobile Friendliness, try the following link:

Critical Path in Project Management

Why a project manager needs to know what is the critical path in a project?

  1. Prove to the management about the time required to complete a project
  2. Determine where to put the critical resources in a project
  3. Determine where to put less experienced resources in the project
  4. Determine which issues or problems in the project needs immediate attention
  5. Determine the risks in the project
