Connecting Up For Intermittent/Nuisance Trips
“Intermittent trips are circuit breakers rightfully operating because of an unknown cause or fault. Nuisance trips are a breaker deeming a non-existent fault has occurred and, in so doing, operates without need.”
“Faultlink International is a fully independent broad-range electrical/electronics fault investigation and analysis consultancy.”
FaultLink International – Electrical Power Diagnostics
Eddy Current Testing (ET) and Infrared/Thermal Testing (IRT) are Interesting Areas where experienced designers can build and manufacture Test Equipment.
Community College Education Resource
These pages have NDT study material for college and Science Educational Pages for High School.
Students can get ideas for original project work on one of these concepts. Choose one area and then research in the web. When i had to build Equipment, it would be difficult to get the catalogs and datasheets of Materials or Methods. Now master the art or searching online, then create your database. Study, Learn and Build !
Direct Read Pocket Dosimeter
“Pocket dosimeters are used to provide the wearer with an immediate reading of his or her exposure to x-rays and gamma rays. As the name implies, they are commonly worn in the pocket. The two types commonly used in industrial radiography are the Direct Read Pocket Dosimeter and the Digital Electronic Dosimeter.”

Product design and development is for the Innovative Engineer. Here Antronics have on display, some projects and design ideas that have been realized.
Antronics Ltd – Project Design Portfolio
A product design by Antronic – The BT redcare alarm monitoring system provides continuous monitoring of a BT telephone line that links a professionally installed alarm system.
Antronics Ltd – Embedded Systems Specialists
Consultancy Services to Clients developing Embedded Microprocessor Systems. Design and development of software/firmware for embedded microprocessor and microcontroller systems. Specialized in Products which need “M2M” applications; ie, “machine-to-machine” communications.
In product development, the most important thing is to communicate and interact with the customer. To get the inputs very clear, goes a long way in customer satisfaction and project’s technical success.
Even if the customer is not able to create a Black Box Specifications but is able to indicate the need or problem. Then you can arrive at the specs by incremental prototyping, to gather full requirements.
The glue/interface Logic families are many. TTL and CMOS is what we all know. TTL is made of the trusted NPN and PNP transistors. CMOS logic is made of Mosfets/FET types.
Making a Logical Choice in Speed-n-Power
CD40XX and Intersil chips were the first CMOS types of IC that became popular. The former were versatile Building Blocks and the Latter created what i would call Flexible Advanced Public ASICs.
CMOS are low power consumption and TTL are nice Speed. In intel chips you could see the transition at 8031 to 80C31, a CMOS with good speed. Now its CMOS everywhere. FET’s rule.
Leroy has created an amazing page that helps you make a choice. I like HCT but these days it appears ACT is better and affordable too.
