Title: GREEN HOME MONITORING SYSTEM – TRANSMITTER
Author: ANTHONY P KUZUB
DATE: 2015 04 01
Description:

REMOTE MONITORING TRANSMITTER

The GREEN HOME MONITORING SYSTEM controls, monitors then transmits the
status of three room lights to a remote monitoring station.

The code below is the local control and transmitter

Three light switches along with motion sensors control the functionality
of the rooms lights.

When the system is enabled:
The light turns on When motion is detected.
Once motion is detected a five second counter Starts.
If motion is not detected within the five seconds The light shut
off saving power.

When the system is disabled:
The light switch controls The light Directly.

A Peak Power cost value is captured based on the time of day.
To Test this feature: apply a slowly 10mHz Sine wave 1.25
Vpp with offset of 0.625V offset to TP7

This moving sine wave is converted to digital by means of A/D convertor

This power cost value is displayed on the segment display
Indicating the value of power throughout the day.

The Status of The System state, switch position, motion detection, Light
status, and Energy cost, are transmitted to a remote monitoring station
via serial port 1.

Description:

The GREEN HOME MONITORING SYSTEM controls, monitors then transmits the
status of three room lights to a remote monitoring station.

The code below is the remote monitoring station

This program receives 2 bytes of data from the transmitter through
Serial port 1. The data is decoded and displayed on a screen by access
of serial port 2 of the controller.

A workstations TERMINAL session connects a a com port to the hardware receiver.

SESSION CONFIGURATION:
BAUD RATE: 9600
DATA BITS: 8
PARITY: NONE
FLOW CONTROL: NONE
EMULATION: ANSI

The Status of the system, switch positions, motion detection, Light status,
and Energy PEAK VALUE displayed on the terminal screen.

A Changing Peak Power cost is applied proportionaly to room cost acumulators.

By Pressing the respective key on the terminal keyboard, the rooms cost will
reset to zero.

Please note that with the exception of the push buttons all states are
ACTIVE HIGH

Dolby atmos

Posted on by

I was lucky enough to get to visit the new Atmos mix room at Deluxe Toronto.  This was the deadest big room I’ve ever been in.  It was impressive to hear the system.  Being a part of the AES gave me an incredible experience of A/B-ing the new IMAX mix room at Technicolor and the Atmos room at Deluxe.   In my opinion the ideas of IMAX immersive technologies translate much better.   The guys at IMAX got it right.

They had a guy from dolby explaining a little about how Atmos renders… very interesting how it translates from room to room.

sound guy Xmas idea: APx515 2-Channel Audio Analyzer

Posted on by

This would be a dream for the test bench.  Simple, robust effective analysis tools!   I would be happy with an old system one… but this would be on the shelf in a heartbeat. 

Screenshot 2014-11-30 10.51.19

The APx515 is a high performance audio analyzer optimized for production test. APx515 has a typical THD+N of –106 dB, a one million point FFT with 24-bit resolution, and 192K digital I/O. It is a best-in-class instrument for its combination of speed, performance, automation, and ease-of-use.

APx515 is a significant product because it delivers the performance and reliability of Audio Precision at a production-level price.

APx is the fastest audio analyzer in the world, returning 21 audio measurements in as fast as 1.2 seconds. It is also the easiest to use, with one-click measurements, custom reporting and sophisticated automation without any programming. A full API and LabVIEW driver is also provided.

This speed and ease-of-use means test will never be a bottleneck, and production line managers can achieve reliable, consistent results compared to the current low-cost alternatives like a distortion analyzer.

For companies outsourcing their production, requiring APx515 on the production line gives tighter control over production, ensuring manufacturers are meeting their contractual requirements.

Moving stuff across the country

I most certainly had a busy “reading week”.  It started with finishing up a job My brother Mike started.  Moving 7 pallets of equipment from my moms garage in Saskatoon.    Followed by great visits with Family and friends.  I’m sorry I did not get the chance to meet with everyone I had planned to visit with.  Things got a little busy in the IT support world and there was so much family to visit!

 Three consoles were packaged and palleted up for shipment across the country.

 Custom made dollies were built for the two large sections of console frames.

Modules were packed, boxed and palleted.  A small fortune in bubble wrap and pallet wrap were employed. 
 2014-10-21 11.04.33-2This is the PSU for a console along with a 1″ Studer A80 8 track Recorder that was made transportable.
I’m excited to work on these projects again in my “Spare time”

Stay tuned for updates of what’s happening with this lot.  We’re very excited for what’s planned :-)

Using a POD 2 switcher

Posted on by

I wanted to add some components to my home listening system, so a switcher was needed. I’ve decided to use a POD 2 switcher…
the POD-2 is a (6) Stereo input – stereo switcher that has the ability to sum all inputs. The output of the switcher feeds a Stereo Penny and Giles fader then directly to the Mackie HR824 speakers.
I’ve got to find a panel… but as far as home friendly user interface goes this is as simple as it gets.

A Social Experiment

Posted on by

I’ve been thinking about a social experiment.
I often take calls from people looking for services, I’ve met a lot of great people in this industry and I do stand by their great work and contributions.   So instead of fielding calls and answering the questions I’ve created a Wizard Services section at http://audioaholics.com/wizard_services

I am asking you my friends to use it to work, get work share work and do work together.  I would like to consider it my rolodex

I’ve got the permission to post a few contacts and will be doing so this week.

Book recommendation: Audio Systems Design and Installation

This is a very well respected read as recommended to me by Neil Muncy.  At the time I was working for him (in exchange for books and resources) he would not let this one go.  Because this book was originally a short run it was available in limited quantities and the used market priced this book at 100$ – 300$  

The recently had an AES special where it was $20 off, but I think it’s a little past the promotion.  If you were to mail the publisher, they may honor it.

Mine is coming hot off the presses:

Anthony,

I have received your order for Audio Systems Design and Installation,
and will notify you as soon as the printer delivers the first copies.

I had been hoping that would be by Sept. 30, but the printer is still
adjusting proofs so it will likely take a bit longer.

Thanks!

Making snakes for a Patching system

We Built some 24 Channel snakes from some re-claimed Blenden Bundles.  All the EDACs were de-pinned and re-inserted into a 90 pin housing.  The other end has been cut to length and re-prepped into various configurations. Dave got some really good practice on this build and his chops have come a long way in a very short time.
