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.

Title: GREEN HOME MONITORING SYSTEM – RECEIVER
Author: ANTHONY P KUZUB
DATE: 2015 04 01
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.

Screen Layout

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

A client asked for a way to balance a guitar pedal so he could send and return Line Level to his guitar pedals.   He wanted a way to use his pedal collection as effect sends.  We came up with a modified Ward-Beck Systems POD-1.  The POD-1 offered op-amp gain adjustment trimmer pots so you are adjusting the gain of the balancing amplifiers.

The un-balanced output impedance is roughly 30Ω and the unbalanced Input Impedance is 47kΩ.  It’s a pretty safe assumption that mopst guitar effects can operate within these ranges.

You could also use this as a re-amp tool and a hyper-transparant Direct Inject box for keyboards and anything unbalanced.

XLR input Balanced +4dBu differential Receiver to an RCA connector to a 1/4″ TS jack that feeds the pedal then return to the opposite.

I was at a Hi Fi shop in Ottawa and they would not demonstrate the RX202 for my brother… Of all the things in the store, this was not for sale for some reason…

here is a video of what it does

Was working on my Micro controller reading and had a need for a calculator to check my work for Successive Approximation of Analog to Digital signals.

WIKIPEDIA:  A successive approximation ADC is a type of analog-to-digital converter that converts a continuous analog waveform into a discrete digital representation via a binary search through all possible quantization levels before finally converging upon a digital output for each conversion.

A colleague posed a very interesting question:
“I am looking for any music/music math wizard help me figure this out. If I am moving the pitch of a song up by 50 cents (a quarter step?) What frequency is A instead of 440?”

Sounded like the kind of math challenge I like:

The answer is 452.893Hz

To test and confirm that it’s calculating properly, this is up 100 cents making G# 440

This is down 100 cents making A# 440

Learning about harmonics, this handy calculator helped with understanding the math.  I love excel!

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.

Screen Shot 2015-01-25 at 12.36.21 PMMartin Pilchner did an amazing job.
They had a guy from dolby explaining a little about how Atmos renders… very interesting how it translates from room to room.
