Fish Oil Telescope Lens

TELESCOPE LENSES MADE FROM FISH OIL
IS A FISH IN YOUR TELESCOPE'S FUTURE?
The Humanoido Lab was successful in creating hundreds of perfectly formed refracting lenses, of varying size, using fish oil. The objective is to create optics using materials other than glass that circumvents the many hours needed for grinding, polishing, figuring, testing and coating. Such methods could be used for rapid creation and deployment of telescopes in low Earth orbit, on non-orbital missions, spinning in deep space, on the lunar surface, and on the Earth.

These lenses employ a clear and pure fish oil extracted from Cod fish that comes from the deep ocean. The surface tension of a substrate is enough to hold the lens in place and is conducive to the collection of droplets and the formation of the convex curvature. The Cod oil has a propensity to collect together and thus perfect round convex lenses are created.

LENSES ARE FORMED WITHOUT SPINNING
The oil is processed before lenses are created. A recipe of cooking the oil precipitates its consistency before the lenses are made and held in place.

It's possible to vary the diameter of the lens from small to large. The amount of collective oil is directly proportional to the diameter of the lens. The size, amount of oil, weight of the lens, amount of surface tension, and the collective attraction of oil to oil, all contribute to the lens FL focal length process.

Small lenses are teased to join other lenses, forming larger lenses in the process. Keeping the process slow in formation will reduce or eliminate bubbles. The fish oil has a very light viscosity keeping the lens interior very pure and bubble free, perhaps significantly more so than plate, pyrex or other glass created specifically for telescopes.

It may be possible to substitute other carrier liquids (instead of water) to form the lenses and vary their properties. For example, using the CRC Handbook of Physics, a higher viscosity material may be found. As the viscosity varies, the size and depth of the lens also varies.

A collective (top right in the photo) was placed in the substrate and allowed to fill. The idea is to produce a creation vessel for a much larger lens. The results were successful and encouraging and could lead to creating much larger refracting telescope lens objectives of extremely pure quality.

So far, the 40-inch Yerkes Refracting Telescope doesn't have much competition as these lenses still remain under the 14-inch diameter mark due to the limitations of the experimental containment vessel.

Mirror Convexure Infinity

REACHING MIRROR INFINITUDE OF CONVEXURE

THE NEVER ENDING FASCINATING INFINITE REFLECTION

For over a hundred years, man has pondered the puzzling mirror condition of infinite reflections.

The Big Brain specifies reaching infinity through the use of various mirrors. Previously, Plano mirrors were used for this experiment, exhibiting the infinity of seemingly endless reflections. This time, the choice of mirrors include two convex mirrors. These are questions surrounding this experiment:

1) Is infinity reflection state achieved?
2) Is infinity reached faster or slower with convex mirrors compared to plano mirrors?
3) How is the speed of infinity defined?

To answer these questions, one must consider two models. One is purely mathematical and theoretical and the other is the real world actual experiment. For our purposes, both are important. First, the obviates of this experiment include the tiny minute offset of the mirror positions that result in the image shifting position as it continues towards an infinite state. This upsets the infinity purity.


The limit of count (black rings) is eight reflections with two convex mirrors
The second real world factor is the the light reflected by a number images become dimmer and dimmer, thus limiting the actual number of reflections. Contrast also becomes less and less. Resolution degrades. In the case of the convex mirror images, the images become smaller and smaller until finally they merge with the finite microscopic silver grains and the compositional material of the mirrors. The smallness of this effect can be negated by telescope and then followed by a microscope, to make the tiny images larger. However, this has limits, unlike the infinity being sought. We therefore postulate in the real world, one must determine the number of visible reflections en-route towards infinity, where infinity is considered condition that is actually never reached with mirrors in the real world. Reaching infinity means the reflections will continue on and on without stopping. But, are there other types of mirrors in the Universe of the macro or the microscopic and the quantum realities that surround us?

Numbered reflections
SETUP
The cost of this experiment is 60 cents. Two plastic quality convex chrome "mini blind spot" mirrors were obtained from Wenzhoushi Senhu Locks, part number #SF-011. One mirror is placed on the table. Next to the mirror is a box. A piece of tape is applied to the top of a second mirror and the mirror is connected to the box, parallel to the base mirror, and are concentrically adjusted. The infinity of reflections are observed and recorded.

50 Cent Computer

One switch 9-LED 50-cent computer for hacking
BIG BRAIN BUYS A NEW 50-CENT COMPUTER
Showing lenses above LEDs

WHO KNEW THE BIKE LIGHT IS A FULL COMPUTER?

 FOR HACKING
This is a simple low cost new preprogrammed computer. This surprising find is made possible by the visions of the Big Brain initiative. Sometimes we need to look at things in a new light.

Imagine the Big Brain on tour within the R.O.C.,  can you predict what it will buy - the large multi-wire gripping clawed head scratcher, the plastic shrunken head, the fierce vicious swimming robot fish, or the 50-cent computer? It was the computer that was too good to pass up. This find came from deep within the mystical night market by the ocean inlet harbor at a dollar store with many unusual and "great find" items priced less than a dollar. This is one amazing example.

OVERVIEW
This item is a complete programmed computer, with a single push button input that controls seven modes of operation and output.

OUTPUT
The output display is made up of seven super bright LEDs enhanced with built in panel of convex lenses that collect and focus the light. It has 360 degree visibility around its perimeter and it's entirely portable, clipping to a belt or to a bike with the enclosed mount.

DISCUSSION & DATA
The cost was US 50 cents though these lights go for US$12 at bike stores. It easily removes from the mount. Designed as a person or bike light, and running from two AAA batteries, this item can be hacked for some very useful parts or used for its intended purpose. This is packaged as part number XY-118 and made in China as a "9 LED Multifunction Caution Light" for uses a a high brightness tail light. The light is claimed to run up to 150 hours or 6.25 continuous days and nights. The interesting icons on the back of the blister pack show the light mounted on a pedestrian's backpack, near the peak roof of a house or tent, inside a car positioned up by the rear window, on the back of a bike, mounted on the front of a person who is skiing, and positioned as an obstacle warning light located by debris.

USAGE
The Big Brain thinks it can be recycled and used for parts, or computer programmed for 7 different multi-functions complete with input and output from processor pins. It runs from a 3-volt power supply, making it compatible with a Parallax Propeller chip, or able to operate independently. It can be used as an 8-bit port display with LEDs showing bits 0-7 and a byte condition in binary code representations and one LED for a power indicator. The nine white LEDs can double as input sensors, the lenses taking parallel light and focusing it onto each LED for greater precision.

ADDITIONAL APPS
The lenses are ideal for making a light beam communications machine where the transmission of parallel light is needed. Nine lenses can drive nine channels of LED electromagnetic radiation. Additional circuits are needed to modulate the LEDs with voice, however, no extra parts are needed to send binary and Morse Code. This is an experimenter's bonanza with many more possible uses!

Wax Eye

Big Brain Gets a Wax Eye
Now don't say "ewe" too quickly as this simple eye uses technology from optics (a single double convex lens) and a piece of waxed paper from a local grocery store. The wax paper is the image forming element and the lens projects the image onto the paper. A sensor or camera is placed behind the paper and photos the image in real time using macro mode. It works well on brighter objects, terrestrial, the Moon and brighter Planets, depending on the diameter of the lens.
