Management of Engineering and Technology

Call it Quotes or Ideas or Instructions, these are thoughts that came from me from the past tech experiences of over twenty years.

Technologies should scale with Infrastructure. Buildings cannot stress the Foundations meant for. Traffic proportional to Road Width. Sync. Software should not overwhelm or Overload Hardware.

Raw Materials - Components - Finished Products. The Entire Processing and Design Chain has to improve, if the final Product has to Shine.

Management of Engineering and Technology

Value Engineering
In Engineering High Value products are those that are a combination of Precision Mechanical + Electrical + Analog + Embedded Microcontroller.

Tools Theory Practice
Excellent Tools alone are not enough, The Techniques & Methods have to be learnt, Then the Skills have to be acquired by Strenuous Practice.

Software 7S
The 7S - Software Should be - Simple, Stable, Spry, Slim, Scalable, Sensible, Scrimping.

Incremental Coding
I do incremental coding - code few lines, test, code again, test. Some extra code to interface for test inputs/outputs (virtual instrument). Incremental Coding, Modular. Test Points.

An Engineered Equation
( technologies + skills + processes ) X ( monitored + managed ) = engineering.

Keep Designs Simple
Circuit or Code - Keep it Simple, Modular, Reusable, Documented, Controlled, Compact, Clear, Creative, Maintainable, Testable, Tunable.

Wireless Home Automation and Application Server

The PC has much Evolved, From XT to AT, then from 286 to 586, the evolutionary trend continues. The Speed: GHz, Space: GB and Software: Linux-XP, have grown rapidly. The other vital things Interface, Networking and Power Consumption moved a bit slower. So some suggestions on the New Desktop for Small Office and Home Standard, that is crucial in the present computing scenario.

Android Open Accessory Kit -  NXP

Enterprise Level Hardware and Software can be extrapolated from this idea for a SOHO. An Enterprise is like a SOHO Cluster. One big Homogeneous Entity is unstable and unreliable. When small varied, self-dependent entities collaborate to form an Enterprise, it is a Cluster of SOHOs, which is a Reliable and Resilient Entity.

From Nomadic Computing

A Green solution could be New Desktop Computing Standard - The quiescent losses in this is only the wifi server cube, which can serve 6 tablets or UMPC. So if 6-12 people are using computers, many desktops need not be on. Tablets, Laptops and Notebooks consume less power and run on batteries. Thin Custom Notebook and Tablet Clients can use one OpenOffice on the WiFi Application Server cube

SOHO Desktop Standard
  • The Desktop Home Computer is the Wireless Router, Power Server.
  • SMPS Power Supply runs Both on 230V-110V AC and 12-24 V DC.
  • Home Wifi Computer, Application and Web Server is just a Cube.
  • Wireless Networked Peripherals, Printers, Drives, Viewers, Inputs.
  • Desktop Wifi Server networks 6 Handhelds and 12 peripherals.
  • Wireless Ethernet LCD Monitor-Keyboard for System Admin.

Wireless USB - Wireless Extension to USB

Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices. Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.

I had to put some files from my USB ThumbDrive to Tablet. That needed a Turn on, on my computer and then plugging things on, and a transfer.

Wireless USB - Wireless Extension to USB

I saw this innovation earlier. Wireless USB - Wireless Extension to USB. And also a USB Drive like product.

I feel this type of thing can be made for stand alone Tablet, extra storage or archive. No need to turn on PC.Also, i think, there may be a need (?), for a very small, tiny Wi-Fi Router with 100 GB storage, media and cache management. That can serve 2 or 3 Tablets and 1 or 2 Netbooks.

An Android Brain for your Bot

The Objective - When your Bot has outgrown your Arduino, it wants to talk, an urge to communicate and Network(Social). A larger brain over the smaller control system is the need. Then a Networked Drove of Bots ! is possible.

Hobby DIY Electronics - Do it Yourself, The World Over.

Use the Arduino for emulating the role of the Spine and an Android System for the Big Networked brain. You can hack an Economy Android Phone to make your Robot an Einstein.

Now for Simulating the Soul, which even the most Advanced Robotic Scientist is unaware of; All you need is Cloud.

An Android Brain for your Bot

How to do that

We have to try create some Robots which are Non-Motor based, Soundless, No Rotary action. Minimum Metal Used, Silicone and Epoxy based parts. They will have 3G and Wi-Fi integrated and the Soul, the Intellect and the Instincts can be upgraded In-system online. The Cloud will be God.

Why the need

The Robot in Literature - Coppélia

Coppélia concerns an inventor, Dr Coppelius, who has made a life-size dancing doll. It is so lifelike that Franz, a village swain, becomes infatuated with it and sets aside his true heart's desire, Swanhilde.

She shows him his folly by dressing as the doll, pretending to make it come to life and ultimately saving him from an untimely end at the hands of the inventor.

The Truth - Swanhilde and her friends find themselves in a large room filled with people. However, the occupants aren't moving. The girls discover that, rather than people, these are life-size mechanical dolls. They quickly wind them up and watch them move. Swanhilde also finds Coppélia behind a curtain and discovers that she, too, is a doll.

The sad part of this Opera and The Nutcracker is that Inventors of Bots are shown as Evil Scientists. We have to clear the stigma by making a Giant King Kong Bot.

Reliable Robust Electronic Products

Use a Servo Stabilizer or CVT Constant Voltage Transformer or at least an Isolation Transformer. The First Defense form HV Surges, Spikes.

High Voltage Polyester & Polypropylene Metallized Capacitors in Stepdown Supplies should be Fire Retardant & Self Healing with a MOV too.

EE Design Library - Electronic Product Design Resource

Tropicalized means immunity or resistance of an equipment in conditions of varied Temperature, RH, Insects, Fungus, Brine, small life form.

Reliable Robust Electronic Products

Reliability by Simplicity

Vital controls should be Simple Electromechanical. Supervisory and Fine Automatic controls are in Embedded Computing. Mechanical Overrides!

<< More Reliable - Mechanical, Electrical, Analog, Digital, Embedded System (Firmware), Computing System (OS+Software) - Less Reliable >>

For a given quality level, more the components or parameters, may reduce reliability. Simpler the solution, more reliable it could be.

A Product's Life

If a product gives three years life with minimum service support it can save itself from building a bad reputation. six years will establish the brand on a long term basis, twelve years of product life you will have the user of the product selling for you.

Connectors and Interconnects

"Never Mix Electrical and Mechanical Connections" (probably from tektronix) this is a rule, more so for power connectors. Strain relief prevents mechanical stress from reaching the connector joints/spring metal. The wire terminations are also cushioned by strain relief.

The PCB and Product Engineering should ensure that the mechanical stress or load is not a job/function/role of the connector. At higher currents a small contact resistance can generate a lot of heat, worsening the contact further, similar to thermal runaway of Power Transistors.

EDA and Product Design Ideas

Product Design Optimization - Some Ideas of mine that are decades old , related to EDA and Product Design.

Make Practical (it works), Affordable, Usable (ergonomics), Safe, Reliable (robust), Durable and Consistent, Maintainable (means servicing) Products.

EDA CAD Circuit Design Software Tools

EDA and Product Design Ideas

Electronics Product Design Development 

Dust and Contamination in Connectors

Once i opened a RF Millivolt Meter of Marconi Instruments. It did not have a spec of dust inside, not even one micron size of dust particle.

Connectors exposed to Environment should not only be Corrosion resistant but also Dust, Grime & Insect Proof! Dummy Covers on exposed units.

Air Vents, Fans & Unused Slots in Modular Instruments. Missing Fasteners in cabinets, gaps in panel components collect Dust & Insects inside

Dust + Moisture + Smoke + Pollutants = Conductive Grime Deposits on PCB, Parts & in-between the IC pins. Can Simulation include this aspect.

Virtual Environmental Testing a part of simulation and EDA, just like Mechanical Modelling and Studying Thermal Gradients on PCB.

AI Dodo with a Wikipedia Brain

Wikipedia Search Results combined with an AI Query and Data-mining Engine integrated with a High Quality Text-to-Speech; can help people hear Answers to Questions they ask. Optional pictures and video on a concealed LCD Screen, Packed into a Feather Bag called "Dolly the Know-all Dodo". A witty, impertinent, extra-smart Bird-Bot. (2009 - Ideas of delabs)

AI Dodo with a Wikipedia Brain

Idea from Polly -

Make a AI Robot in the form of a Cartoon Parakeet. Something like polly the techno parrot below. When you ask a question or a unique term like "Solar Energy" or "Vitamin C" it can use its AI - Artificial Intelligence to read out a Wikipedia Page and if not Satisfied browse the web internally and suggest alternative pages to read out. It can have a Dockable Tablet Interface too for Visualizing its AI and Articles.

Who made Polly  Shown on the right in CrossSection - Rob and Roberta Radtek

 "Direct from the Institute of Robotic Technology comes this amazing interactive robot pet-- POLLY THE TEKNO PARROT! Polly talks with people he senses around him just like a real parrot. Polly's electronic cuircuits can detect motion, sound, light and even touch. He will snore off to sleep at night and wake up in the morning. If you pet him, he will "coo" and move his wings. "

These are some sites that help you read out wikipedia.

Pediaphon App in the Android Market!MP3 files, play lists and podcast automatically generated from Wikipedia!  Let your computer read out the Wikipedia for you!

"Learning during jogging and driving! E-learning and m-learning with MP3 players and mobile phones! A podcast and a winamp play list will be generated too."

Wiki Out Loud: Wikipedia Entries on Audio - "A few nights ago I was at the office and the ol' brain was fried. I decide to take a couple of hours "off" and record some Wikipedia entries on audio."
