ESP8266 WiFi module intro

So I received yesterday 2 of these nice ESP8266 WiFi module:

Bought it from Ebay at 3.58$ each including shipping:

It did take about 5 weeks to get here, but I was in no rush.

One thing to be carefull, this is a 3.3v device do do not plug it to anything that will bring 5v to it's inputs or you will destroy it.

Found this nice how to on using simple resistor voltage divisor and transistor to drive this module from anything 5v:

Will update in a later post my progress on using this what seems to be pretty versatile module.

IoT/IoE, hardware, electronics...And some Ruby to rule them all !

So last night (May 19th 2015) did a small talk at the Montreal.rb meetup (www.montreal.rb).

While most talk at these meetup are Ruby/Rails related my talk was more on electronics, DIY/Maker stuff, IoT/IoE and yes how to use Ruby to work/control these embedded platforms.

The following is a link to the PDF version of the slides used during the presentation:
