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.

The Mini Metrology Lab - Conrad Hoffman

This is a Article by Conrad Hoffman in "Electronics Now, April 1996".He has an intriguing collection of electronics and Mechanical DIY Tips and Ideas in his site.

The Mini Metrology Lab - Conrad Hoffman

The Mini Metrology Lab - Conrad Hoffman

His "Electronic Mess" section has many pages on repairing and restoring old instruments and equipment.

An Excerpt from his pages is a Reading Pleasure due to his rich experience and enticing language. 

Troubleshooting Audio Electronics
I ain't gonna lie. You won't be a master troubleshooter after reading a couple pages here. Hopefully, what I can do is give you the ability to form a logical plan of attack.

Troubleshooting is done mostly with the mind, not with the soldering iron. We all have problems that get the better of us, at least for a while, but approaching the situation as an interesting puzzle, rather than an unpleasant task to be suffered through, will make the work go quickly.

 Success will come from a 3-prong approach, a combination of understanding the circuit, having the means to test it and being in the right frame of mind to correctly interpret the test data. Never underestimate that third component.
He also has a Design and Testing Services called  Deep Run Design.

Two PCB Mills - Jonathan Ward and Ilan Moyer

Make your own PCB Mechanical Routing/Erosion/Milling Machine at a low cost.

PCB Mill - Jonathan Ward - MIT

"Design a low cost circuit board milling machine optimized to be mass-produced."

The overall device has a working area of 4" x 6" with a footprint roughly the size of a letter-sized sheet of paper. Capstan drives were chosen for their simplicity and low cost, and also serve as torque limiters to prevent excessive loads on the small-diameter drive cables.
