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.

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

Super cool Philips console

rom the sale:

 

Up for sale is a rare 1970’s Philips LDC25 console. The console features 24 transformer balanced mic/line inputs, great sounding 3 band EQ, 2 aux sends per channel and 4 transformer balanced output busses. 16 of the input channels are early discrete LDC modules and the last 8 feature later 1970’s IC based modules – both sets of modules sound, for all intents and purposes, identical. The sound of this desk is punchy, clean and very hi-fi sounding – easily on par with anything built by Neve/Api/Studer from the same era. These were built by Philips in Holland for recording mostly classical music, but were built to a very high standard and also sound fantastic on modern tracks which require a very forward sounding mix with a very low noise floor. I bought this to use as the main console in our studio due to the high build quality, high track count, compact size, multiple sends and versatile output options – but I need to raise money for the completion of our house restoration which takes priority to the studio build out. All the manuals and module documentation are included. The console will be fully gone through by a qualified technician prior to shipping and/or pickup. All input/output wiring is terminated to panel mounted XLR connectors, so all you need to do is connect the console to your DAW/tape machine and you are ready to record – no wiring necessary.
The console is located two hours west of Chicago in IL. I’m happy to assist with freight shipping, but please understand due to the fragile nature of vintage electronics any risk associated with shipping is going to be your responsibility. Local pickup is welcome. Payment by check or wire transfer only for this listing. Please feel free to contact me with any questions you might have. I hope this console finds a good home!

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 :-)

I was over at Ward-Beck the other week and saw some really nice turrets coming off the line.   Hand Made, versatile and robust.
Just what you like to see in something that’s going to have the crap kicked out of it by announcers and A2s.

this one is “en francais” – j’aimme le Talké / Backé button

Kevin was mentioning an updated version of this box…

There was also a R257-1 out with a built in 8 source router.  2014-01-20 17.29.16

RUPERT NEVE!!!!

you know… I love this man and am forever in his debt.  He’s made laboratory grade audio equipment available to music / broadcast industry for many years and his standards and  interests have grown since his beginning.  Truly a childlike interest in pushing the boundaries of the craft he practices. He applies raw physics to sound and you should watch this as a whole to appreciate the brilliance of his passion and dedication.  

I’m glad someone as enthusiastic as Hutch Hutchison is at his side absorbing it all. (though he left RND)

Long live limitless analog technology!
Long live the passionate, curious and boundary pushing!
Long live Rupert Neve
