Fixing Logitech trackball performance
I love these Logitech Marble Mouse trackballs, I have one for every computer. After a few years they slow down physically. Cleaning the dust off does not help enough, something different needed to be applied. I’ve been researching lubricants and oils, doing some tests with households; but I think I’ve found the perfect fluid. Ian Gomes of Union Sound Company made a recommendation a few years back for Penny and Giles faders. A quick amazon search lead me to Lucas Silicone Shock fluid. I must report that it is the perfect product for this application. If you need a drop, I’ll send you a q-tip of it in the mail.
Generating Code with spreadsheet for Keyboard Assignments of CADSOFT Eagle
I needed a way of Generating Code, lots of code. In cadsoft eagle, the Keyboard Assignments are completely user customizable. They have a script language that allows you to modify the software. I’ve used hundreds of the ULP and SCRs and decided to write my own Generator.
Necessity is the mother of all innovation.

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
ACTIVE HIGH

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.

Sound guy xmas Idea – CN37 Light guided Connector Assembly
Got a Call from Christopher today. “I do a lot of EDACs” I said. He said “what you really want is the CB37 Light Director Board“
And he was right.
sound guy Xmas idea: APx515 2-Channel Audio Analyzer
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.
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.
