SmartWindow with Economy Dust Frame

Windows and Ventilators can have a Dust Frame or Solid Curtain. This can be fixed to windows like the Venetian Blinds but have to be leak proof on on the four sides. Mainly for Tropical and Equatorial Climates or Dusty areas near Roads etc.

SmartWindow with Economy Dust Frame

Theory Points of Study

Layer-1 - Blocks most reptiles and Insects. Mosquitos to Fruit Flies. Aperture of Grid 1 sq mm. Material Aluminum.

Layer-2 - Another Layer similar to above, but facing the Outside Garden/Road. Aluminum Mesh 5 sq mm holes, resist Big Rats and others. It is thick and strong. Prevent Small Animals, Birds too.

The layers are as large as windows and are separated by 5-10mm by 12 nylon spacers. These may have small pins fixed in the gap in many places for "Action of Points" .

Electronics -

Layer-1 is anode, Layer-2 is cathode. Very High Voltage of Very Low Current, ionize air and coagulate dust, smells, pollen and other floating colloids. The plates when touched by Humans cannot cause any harm. Current less that 100 microamps. This ionizer powered by an isolated 24V adapter, draws very low power so it can be kept on all the times

Gaurd Layers -

Finger Gaurd layers on either side made of a decorative design with apertures smaller than fingers made of Environment Resistant Plastic or Epoxy. The layers are as large as the windows and can be the aesthetic part.

Solar Air Cleaner and Humidifier ACH Option

This is a Solar energy based Air Cleaner and Humidifier that covers 1/4 of the window like a Box-Slab at the Top of Window. It is optional and an addon internal module to the DustFrame.

The Solar Panel is as wide as window and fitted on top of windows at an angle outside. The length can be around 6 inches or less. The ACH fitted inside is 1/4th or less the height of window. The rest of window 3/4 is open for fresh air but the air is cleaned by ionizer frame like in explanation above.

The 1/4 ACH is a Box 6 inches deep on the inside, it is sealed but with a place to pour or guide water thru a mini water pipe, like the tubes used in Intravenous Systems used in hospitals.

The water collects at bottom of the box and drawn upward by a capillary action by an array of cotton wicks in matrix formation. The wicks grow from the floor of box to top.

Tiny row of low power fans powered by solar and rechargeable battery, draw air thru the ionizer layer and blows on the wicks array. The air exiting from this box is cool, clean and recharged with some humidity. it could also be one fan with long vertical geared turbine barrel plastic fin too, this sucks the air and blows on the wet wicks.

This system reduces dust, toxic colloids and allergy causants. It also prevents mosquito, flies, rodents and other small pests. It recharges the air with some humidity that keeps the room healthy and fresh. It consumes very low power and can be run on solar energy. The wet wicks also add a bit of cooling if the air is too warm.

Thermoelectric Breakthrough can Replace IC Engines

IC Engines or Internal Combustion Engines are used in all types of Motor Vehicles. They convert Organic Fuel to Motion by tiny combustive explosions in a Cylinder-Piston arrangement. The use of Electricity here is only the spark for ignition.

Revolutionary Balloon Anti-gravity Car

Balloon Antigravity Car

These have a very low efficiency analogous to the Incandescent Tungsten Filament Bulb, The traditional bulb is being replaced by the emerging Energy Efficient LED Lighting Technology.

If we can convert Ethanol Fuel to heat by combustion, that is easy. Then the entire heat is absorbed by Thermoelectric Cell Arrays, like the Solar Cells absorb The radiation from the sun. The EMF from the Thermoelectric Cell Array can be a cascaded to generate enough electricity to charge the Rechargeable Batteries in an Electric Vehicle.

The most important thing is ..... The Material/Compound that can give a good Heat to Electricity Conversion, has still not been discovered. This has be as good as a Solar Cell.

Power Electronics - SMPS, Regulated Supply, SSR.
Some Breakthrough in Semiconductor Physics, Nanotechnology, Material Science or Electrochemistry by the Scientists in Fundamental Research and Applied Science, can make the Internal Combustion Engine Obsolete.

Thermal Electricity can also make possible, 'on the fly' Electricity from anything that can burn. Coal, wood, twigs, dried leaves, biogas, ethanol can fire Mini Thermal Engines; that make Heat into Electricity to drive Electric Motors backed up by supercaps or rechargeable batteries.

The only other way is to offset gravity as shown in the right, this was a graphic i made in 1999 for a poem on my website.

Automobile Ideas from 2002

Some things i had written online around 2002 on cars.

Cars can have multiple skins like Winamp

If you use organic flexible LEDs, encapsulated in transparent poly-sulphone or some silicones. And the RGB triad matrix of LEDs are driven by a computer system to make it work like a flexible LCD screen. It can be used to form a skin for a car. Only there will be no high resolution, but it will do.

This flexible layer is fixed on the car like a permanent cap. Now with the onboard graphics synthesis embedded car computer you can choose any jpg, png or gif textured tile or make your own. Then output the tile or wallpaper to the car exterior LED matrix skin. Now the Car has become skinnable. Not just colors but fine textures are possible.

Automobile Ideas from 2002

Now with a Bluetooth enabled Human Mood Monitor plugin you can make the car exterior to reflect the mood of the life-forms inside. This will make a road alive and traffic jams very colorful.

Simple Automobile Safety Radar

There must be a very affordable automobile radar with just a 10-20 feet radius around the vehicle. This should display as a graphic on the dashboard as some of the very old 2D car games. This radar must be based on sonar or infra red to avoid additional EMI-RFI pollution and confusion. The display should show all objects which include people, small animals, kerb and wall.

Microcontroller - 8051, 8052, OpCodes, Analog Interface.
The sensor has to be a multiple sensor, static belt one near wheels and one at the roof of automobile. The display device on car should be TCP-IP so that you can monitor your vehicle with your cellphone, PDA or any browser.

Electronic Solar Umbrella

There are places like your Backyard, outdoors, a village... where your Gadgets will stop working !!!

You will feel suffocated when your Smartphone or Tablet fails to respond to your caring strokes. Your Dupey is perishing due to Undernourishment. All you need is "Electronic Solar Umbrella" which was invented by me delabs on June 1st 2014.

Electronic Solar Umbrella

The Red Light is for Data Networking SmartUmbrellas using Advanced Multi-Threaded Infra Red Technology.

SUN - Smart Umbrella Networking

Resources - Electronic Firms and Electronic Projects.
I just invented the SmartUmbrella - My Drone is Rushing to the Patent Office.

(Keep this confidential till my drone returns safely, the beagle boys are using Blimps with Large Magnets to capture Drones.)

Measureall Workbench Test Instrument

This was a Student Project of mine, it is a very basic instruments that could do most of the tasks on a test bench.

The cabinet used, was available as a part of a Hi-Fi DIY System, The Range and Mode switches were Modular Stackable Interlocked MultiPole Switches. The rest of the Interface were wirewound pots, jacks, sockets and plugs. The front panel was Engraved Acrylic, the panel was the toughest issue we tackled.

I wanted it to look well engineered, at least on the outside. It was a total analog instrument except for the digital indication of ICL7107. Thanks to 'Intersil Hot Ideas' Applications Book.

The above belong to an instrument Measureall shown below.

Tale of Three LED Lamps

Two lamps (china make)  had gone bad due to overvoltage or transients. I created a Third Lamp out of them that was a Rechargeable Table Lamp. Rechargeable Table Lamp This was made many years back. Now people are making more Robust lamps.

A Dockable and rechargeable Torch. Table lamp when Docked. All Green, Only LED, no carbons footprint like thing.

From Hobby Hound - DIY Electronics

This is as Green as you can get. It Recycled two lamps, one a Florescent Desk Lamp, the other an Emergency Lamp. Both failed in a few weeks after commissioning in our residential infrastructure (read 'used at home'). It is green again as it is LED and rechargeable.

A new circuit design with mosfet. A Dockable cup with quick detach connector made of Sawn off Mouth-Wash Bottle. Finger cuts took weeks to heal. A Metal Plate that was part of a instrumentation chassis (my excess inventory). This plate belonged to an electroplating unit i designed. Many SSR (Solid State Relay) Polycarbonate Stickers on plate for lamination.

The Lamp became Head Heavy and kept falling. Then it was affixed with a Nut-n-Bolt to the sturdy 316 grade Steel Plate.


Moral - When we are praised or get some money, head becomes heavy. Then we stroll in a Intoxicated way, till we fall with a Thud.

Elektrick the Power Jedi

Elektrick the Power Jedi

The main problem is, sometimes the voltages may climb more than 50% of rated voltages. The thumb rule is, if Mains supply is rated at 100V AC then the Appliance must withstand jolts upto 200 V AC for upto 10 Seconds. Else use a tripping device in the Home or Office Switchboard.

Home or Office should have OverVoltage Relay, OverLoad (OverCurrent) Fuse, Earth Leakage Tripper, Under-Voltage shutoff or Boost. Lastly Transformer Isolation and Excellent Earth and Lightning Return Systems.

Stereo Audio Music Players

40 Watts Hi-Fi Music System - Stereo Music player with Tuner, 1986, LED VU meter and Analog VU meter.

SAN 20

This was done as repairing home electronics was my hobby in school days, I learnt by building Amplifiers based only on transistors from the Old Philips Circuits and Books. The above one is TDA2020 20 Watts Per Channel, with LED input level meter and moving-coil output meters.

It would have a 5 pin din input and RCA speaker output, input for phono, tape, etc. The Speakers had a woofer, tweeter and midrange with passive crossover network.

SAN 20 Speakers

Stereo Adapter for Portable Music Player

Low Cost Stereo Adapter 20 Watts for Portable Music Player 1984, Bass Treble and Presence.

Portable Music Player

This was a TB810 based 10+10 Watts Stereo Amplifier with LM381 or 2 Preamplifier, The portable player docks in a wooden cabinet. There was no IR, Wi-Fi or Bluetooth in those days, so the device would interface with amp thru a stereo ear-phone socket-jack system with a shielded cable. Bass, treble and Presence as per an old phillps audio amp book.
