DesignSoft - Learn with Edison Newton Tina

Edison - provides a unique new environment for learning electricity and electronics. Teachers, students and electronics enthusiasts can use digitally scanned photorealistic components, a solderless breadboard, virtual instruments, sound and animation.......

DesignSoft - Learn with Edison Newton Tina

Select realistic batteries, resistors, diodes, LEDs, transistors, logic gates, flip-flops, and even microcontrollers & integrated circuits all easily available on the shelves of your multimedia lab. Drag them onto your "breadboard" and wire them together with your mouse. Your circuit begins working immediately so you can test and troubleshoot it with virtual instruments. In addition, Edison automatically prepares a standard schematic diagram and displays it simultaneously.

Tina - The Complete Electronics Lab

Powerful yet affordable software package for analyzing, designing and real time testing analog, digital, VHDL, MCU, and mixed electronic circuits and their PCB layouts. You can also analyze RF, communication, optoelectronic circuits, test & debug microcontroller applications.

A unique feature of TINA that you can bring your circuit to life with the optional USB controlled TINALab II hardware which turns your computer into a powerful, multifunction T&M instrument. Electrical engineers will find TINA an easy to use, high performance tool, while educators will welcome its unique features for the training environment.

Optical Retro-Reflective Proximity Switch

This circuit is used to detect objects by reflected infrared light. It can be built into a cylindrical enclosure just like an inductive proximity switch.
This is also useful as a level detector for colored liquids like oil. This has some immunity to ambient sunlight as it detects ac pulses.

Optical Retro-Reflective Proximity Switch
This is a Hand Crafted PCB Artwork done by a PCB Vendor years back, this method may be used even today.

Optical Proximity Switch - PCB

PCB Design -
This Layout may have many jumpers and may need to be cleared of Hairline shorts which has happened after i scanned it, cleaned it and enhanced it using image manipulation software.

This PCB would go into a 30mm Nickel Plated Brass threaded tube, with Epoxy or Teflon ends. These were turned components as quantities made were small. An Optical Proximity Sensor that would fit the same place as the eddy current or Inductive sensors, in existing machines. It could work a longer distance and could detect Non-Metals and even translucent fluids.

Pressure Measurement and Control

Pressure is the next most important parameter after Temperature. In Hydraulics and Pneumatics, the measurement, indication, control and logging-charting of pressure is indispensable.

Popular Pressure Sensors are based on either Piezoresistive or Strain-Gauge Technologies. Strain-Gauge types can be Metal Foil or Semiconductor Film.

Pressure and Flow Control Applications - delabs

The Analog Strip Chart Recorder is used in Simple Systems where a Record or Report has to be generated. Data Loggers and PC based Data Acquisition Systems expand this capability by making the Data Electronically Accessible for Charting-Analysis and Reporting using database applications.
The Liquid-Fluid Level in containers of uniform cross-section can be computed by measuring the pressure of the fluid head. In cases where levels of semi-volatile fluids are measured, sensors with Micro-watts of power usage or data transmission is required to protect from sparking related accidents. Even Zener Barriers can help reduce risks due to wrong connections or cross connection due to cable damages.

In the field, due to various constrains many safety practices can be overlooked or circumvented. The Sensors and System design must be over-engineered in some cases to safeguard man-machine assets.
