The NEW Chromecast

Rational 

Cables, cables cables...  Several years ago I started to look for a good solution to replace the USB and VGA video "hook-ups" from a User Device (read: chromebook, tablet, laptop, cell phone) to a projector (or a display device).

Why? You might ask.  First off, by today's standards, VGA is a "low resolution" standard.  The projector connection also required a USB to the audio systems of the device presenting so not one but TWO cables were required to the device.  One of a laptops or tablets strength is "portability", but when tethered to a projector, it looked more like astronaut to a space station; very limited "portability".   (Along with the cords looking like a lifeline!)

Enter HDMI ....
"HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitorvideo projectordigital television, or digital audio device.[4] HDMI is a digital replacement for analog video standards" -- (Wikipedia, 2017)

In combination with the newly updated Chrome browser,  it's now possible to broadcast to a Chromecast device, everything that you can place on an user's display.  This used to be limited to ONLY what was inside the browser, but now it's ANYTHING you can see on your device.  This includes audio and video, at much higher (read: looks and sounds nicer) quality!  (In Fact at the same quality as what your device can handle.)

Also, once your device sends to the Chromecast device, it's no longer required to keep streaming.  That means you can send audio and video from an Internet source to the Chromecast device, and get your device out of the connection to the Chromecast, no cables required!

Requirements:

User Device: Chrome (Chromebook or Chrome browser), and the Chromecast Extension enabled.  *
Receiving Device: An HDMI port.**

HDMI Port

Assumptions: 
     
     User Device:
  1.  A Version 2 Chromecast device.
  2. Updated Chome (must be Version 61.0.3163.100 or higher.)
    Device:
  1.  An HDMI port (to attach the Chromecast device to).
Projectors (or Multi-Purpose Display Devices) must have an HDMI port, and the Chromecast device in the same LAN as the User Device.  The setup of the Chromecast device is a three sterp process that involves the User device going to this site.

New Paging System...

Last Thursday,  Integrity Communications , Inc. put speakers up around the hallways on the second floor, in the hallway in ffront of the Kindergarten room, and in the Art and Music rooms on the first floor.  These speakers use an IP phone to get their sound.  If the IP phone isn't up, the speakers are limited only to the original handsets that worked before the new paginig system was installed. Now last Thursday, Integrity tested the system and it seemed to work g=fine.  However over the weekend the phone reset and without that phone working, there was no sound on speakers.  Yesterday Integrity stopped by and reset the phone.  Now all seems fine. You may hear me testing the speakers a few times.  I want to make sure the system is stable and will meet our needs. thankx, mikel

New Times in New Places!

Tech Times Hi Everyone! Welcome to this years version of most of Hyde Park Elementary School in Morrisville (HPES@Plaza).  Also to the 6th graders, living the "high life", at the Tech. Center, you are not forgotten. Let me introduce myself, I'm Mike Lambert and I'm the new Technology Coordinator for Hyde Park.  I'm a Systems Engineer with many (40+) years experience in Technology, including business systems and education.  I've been "around" since mainframe computer days and have worked on many projects ranging from enabling TCP/IP audio in the New York Subway, to creating state wide video systems, and lots of school networking.  I'm a former President of VITA-Learn, and I'm active in technology at many levels. I will start here by confirming to you that technology moves at a fast and nearly impossible to keep up with pace!  New items today, can easily be "old" items by next week (sometimes by the next day)!

Learn Basic Programming Skills....

Coding Fun Starting next Tuesday, (November 7th) I'm going to be teaching a programming class.  This class is going to be about using programming skills to make applications using MIT's Application Inventor 2. (See  http://appinventor.mit.edu .) The interesting thing about this developmental environment is it's all contained in the cloud and can produce some very complex Android applications.  To get a feel for App Inventor 2, see the video below: Application Inventor 2 This class will starts with the basics of the environment and then go on to make some nifty stuff!  If you're interested, take a look! mikel
