Gadgets as Visual Interface for Process Control

Here is is gadget GUI for Industrial Process control, WebApps. The buttons make a sound and Light up internal LED lamps. Power On-Off control, Digital Timer; Start, Reset Scroll and Select are the controls.

An Image ScreenShot is here.

Digital Timer Gadget Visual Interface

I will first make some simple examples with this UI. Then i will try to interface the javascript with PHP-MYSQL Application. I am just Thinking Loud. This makes a Globally Distributed Process Control Possible. :~) . You can Use html-js-php-msql. You can use ajax-python-perl too.

Digital Timer Gadget Visual Interface

But for now, back to earth, I will just complete some more simple tutorial gadgets. This Idea of mine is Open Source, please keep it that way.

Costing of EE Products

This is a Crude Costing Formulae based on my Ideas which is called "Gut-Feel Thumb-Rule Methodology." Even Though i am probably the only follower of this popular System, I am sure it is worth a casual Look.

Costing of EE Products

RM - Raw Material Cost         SP - Selling Price to Distributor

Reserves are for Dry days, Employee Fund is to reduce Attrition and Layoff. I was costing the products as a Proprietor, Managing Director and as an R&D Engineer too.

This post is just to enlighten you of the intricacies involved. It is merely the Tip of the IceBerg. You will need a Spreadsheet and lot of foresight and hindsight to make a practical costing.

Management Methodology 

This rule is for products made in good numbers. Large scale production costs may go down. Custom designed products made in small numbers the price may double. The cost of Engineering and IP has not been taken to consideration. It has been covered by a 10% Research Cost.

All this assuming we make products of reasonable quality and reliability. Build a reputation by good customer service when the product fails. So this will add into the cost depending upon the organization.

The grey areas in this costing are "Sourcing quality Raw Materials and Parts". Designing and Engineering "Reliable and Robust Products" . Customer Support at site or field may be expensive and warranty too.

Better to be Honest, Transparent and build a Brand Reputation for a Long Term company Success.

Reliability of Electronic Products

I have been in Product Design, Manufacturing and Marketing of Electronic Products/components. I have also been, like many of you, a customer.

It is very important that the customer gets a Reliable, Sturdy, Usable and Dependable product. This is what makes the Good Brands which in turn add to the Company Reputation and value.

Bathtub Curve - Wikipedia

The most important is the "Direct Customer Support" when a product fails or user finds it difficult to operate.  This include Prompt Product Service and Repairs. Any laxity or high-handedness or a Ping-Pong Customer Support can cause acute Brand Blindness that could even become Hereditary. Your brand can be shunned by a Family for generations and they also propagate negative marketing.

Reliability of Electronic Products

Your Product and Your Customer are like Family. Protect it and Nourish it for your own good.

The bathtub curve is widely used in reliability engineering. It describes a particular form of the hazard function which comprises three parts:
  • The first part is a decreasing failure rate, known as early failures.
  • The second part is a constant failure rate, known as random failures.
  • The third part is an increasing failure rate, known as wear-out failures.
  • The name is derived from the cross-sectional shape of a bathtub.
