History of Allied Electronics -

1928: Allied Radio was established as the radio parts distribution arm of Columbia Radio Corporation. The company was soon to become one of the most recognizable names in the electronics industry.

1995: Allied is the first electronics distribution company to come out with a CD-ROM catalog and quickly followed-up by entering the e-commerce arena with the launch of a web site.

FM Remote Speaker System

A high quality, noise free, wireless FM transmitter/receiver may be made using the LM566 VCO and LM565 PLL Detector. The LM566 VCO is used to convert the program material into FM format, which is then transformer coupled to standard power lines. At the receiver end the material is detected from the power lines and demodulated by the LM565.

National Semiconductor Application Note 146 June 1975

The important difference between this carrier system and others is its excellent quality and freedom from noise. Whereas the ordinary wireless intercom uses an AM carrier and exhibits a poor signal-to-noise ratio (S/N), the system described here uses an FM carrier for inherent freedom from noise and a PLL detection system for additional noise rejection.

Carrier System Transmitter

Carrier System Transmitter
Two input terminals are provided so that both LEFT and RIGHT signals of a stereo set may be combined for mono transmission to a single remote speaker if desired. The input signal level is adjustable by R1 to prevent overmodulation of the carrier. Adding C2 across each input resistor R7 and R8 improves the frequency response to 20 kHz as shown inFigure 5. Although casual listening does not demand such performance, it could be desired in some circumstances.

Carrier System Receiver

Carrier System Receiver
The receiver amplifies, limits, and demodulates the received FM signal in the presence of line transient interference sometimes as high as several hundred volts peak. In addition, it provides audio mute in the absence of carrier and2.5W output to a speaker

Franks Electron tube Pages

"At the age of 10 we moved to Copenhagen for about 2 years. I had some friends there who knew that I liked old radios so regularly someone brought me one. (See my picture at the main page) Among them was the Bang & Olufsen - Grand Prix 48 K (photo). I liked this radio so much that I wanted to make it work again. There was not much wrong so I got it working. Later when we were back in Eindhoven, I made so many ......."

The tube data resides on several mirror sites in several countries and they are exactly equal, except for the Poland site which additionally has been equipped with a tube search.

More about Frank's Experiments

"Back in Eindhoven, there where the 60's. Radio Luxembourg on my B&O etc. I got interest in guitars and amplifiers. I built several Amps. My first amp was something with the EF11 and the EL3. I also built a copy of the Philips EL6431 Amplifier. (That's where the output transformer of my B&O radio went) In Eindhoven there was a repair shop called 'De Radiodokter'. He had some old TV chassis in the display for 5 guilders each. When I had saved enough money, I bought some. Then when I was about 16 I made my first really working TV from these parts."

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.

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."

Solar Piezoelectric Cell

Sometime around 2008 i wrote this. It is more of Humor and less of Reality.

Vibration  Pressure are Related, Pressure is related to Temperature, Sunlight has Infra Red & Heating Ability. This should Ring some Bell.

You have Heard of Solar Cells and Panels, Sunlight to Power. Heard of Piezoelectric Energy, Vibration to Electricity

Solar Calculator

Solar - Heat - Pressure - Vibration - Electricity !! New Hybrid Solar Cell ! Someone has to just Invent it. It should Flash a few Lamps.

Micro Mech Lithography. Tiny Cantilevers, Tiny Silicone bulb of Volatile Liquid. Mini Lens Heats the bulb. Cantilever is bent a few Microns.

Power Electronics & Solar Energy

Pressure sensitive valve deflates Bulb suddenly, The Piezoelectric Cantilever goes Twang. The Electric Pulses charge a Supercap and battery.

The Vaporized Liquid has Condensed, it goes back to the cells by Gravity, The Shrunk Bulb draws the liquid. Ready for next Cycle.

If it works, credit me, else all credits go to Tweedledum and Tweedledee.
