GREEN HOME MONITORING SYSTEM
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.
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

SUCCESSIVE APPROXIMATION ADC CALCULATOR
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.

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

My first microphone pre-amp design
Doing a school project is the PERFECT excuse to design build a test my first ground up original Microphone pre-amp!
I learned these buzzwords from the Kimber cable guy:
The imaging is fantastic, totally forward sounding with edge AND detail on the soundstage. Though precise, there isn’t that analytical flavour tainting the dry sound in the copper typically found in other microphone pre-amps. Micro-clipping isn’t an issue anymore! By a factor of at leased 10, the noise floor is lower than you’d ever expect. With an un-constrained matrix, painting the sound stage will be a pleasure. Tipping the value curve, the proportions are just right.
But honestly… I’ve not heard it yet, or kimber cable for that matter.
Seriously though… it’s a transformer coupled double balanced class A instrumentation pre-amp using only the best. Actual results to follow!

Finished a project for school
I had to build a 1 watt Class AB – Amplifier for an Electronics devices course. The school has an LPKF PCB prototyping machine to make these PCBs with. I’m not going to turn down the chance to have the boards made up so any project that involves PCB layout, I will over do it! The machine does 2 sided boards and with a special baking process plates the holes. I only learned this after I spent all the time making it single sided with a ground plane on top. So many lessons learned on this one.
After two revisions and some trace cutting, she’s alive. I used some Phoenix connectors on the board for connection. I will never make a board without some simple way to connect or disconnect it. Also, the idea of a PCB copper heat-sink was a bad idea. I imagine the copper has to be thin for the machine to router… so chunks of aluminium were added on the back. Thing gets rather hot.
