Successful Science Story: Have a look to Venture With

Physicochemcial parameters are industrial for formulations and quality controls of materials like cosmetics, inks, tooth pastes, shaving and facial creams etc. His other development is Econoburette for risk free Chemistry titrations in schools, college, R & D centers using chemicals at semi-micro amounts. The Visionmeter is a remarkable invention where visually challenged can learn science and technology and opens many avenues for their employments like quality controls of soaps and detergents, milk, oils, inks, syrups, emulsions etc. The motto of research is enriching quality of life and the society at large and a fabulous world of instrumentation can skill for better life style and standard for everyone.

Every technique instrumental requires some fundamental tone and overtone as a base for working as a probe. In this context there are many instrumental devices like electron based instruments like electron scattering chemical analysis (ESCA), non-electron based instrument like atomic force microscopy (AFM), the nucleus based instrument like X-ray fluorescence (XRF) and low energy instrument like ultraviolet (UV) and infrared (IR). Similarly a medium energy based instruments proton nuclear magnetic resonance (HNMR), the higher energy instrument like carbon (C13NMR). The Survismeter, Econoburette and Visionmeter come under a field of external forces caused by valence electron. Many instruments like conductivity meter, pH meter, potentiometer, colorimeter, wet lab tests, calorimeter which also fall under valence electron activities.

The world of instrumentation for inventors, industries, users and interpreters of data has been the most attractive fascination. The theory of instruments basically works on a principal of accuracy, precision and reproducibility. Gaussian distribution curve is first and foremost device to understand and apply in data and any instrumental invention must be supported by the Gaussian data metrics. This gives an additional confidence, courage to users and a level of skill and operational capability. Many simple laboratory equipments like pipette, burette, test tubes, kjaldal Jar, distribution apparatus, ignition tube, melting point capillary do explain a theory of valence electron mechanism if is attended properly.

Scientific method

Trends of modern research are very practical and with fruitful output to benefit, enrich national and international community with simple and truly useful works. Lecturing other’s work is substantial to disseminate the scientific information to rest of the users or learners but original contributions in establishing new landmarks and fundamentals in science and technology is a milestone and a noble cause for society with multifaceted uses in several branches of modern sciences. With simple diversification and giving new terminology like green chemistry, nanotechnology etc may not help much until and unless new fundamentals are incorporated. Though these synonyms of fundamental science are there for understanding a use based scientific method at micro and nano levels just to be economic and smart to harness maximum out put out of a particular process to be undertaken. Newton, Einstein, Gilbert, Gibb, Mandelef, Heisenberg and many others are remembered for original contributions not from lecturing on other’s contributions except consulting as reference materials.

Frequently several media clippings are noted by a common man but all of them are short lived and very few takes practical shape and place in the society and the science fields otherwise many ideas come across and make a hype but few realistic exercises take a practical shape and become a successful science story (SSS). The SSS motivates the rest of the world and of course it becomes a boon in the scientific world and ethical part of the scientists. Thus hype base unrealistic ideas may be avoided on moral grounds as such irresponsible acts spoil the image of real workers. However there is no any idea which is unrealistic provided one is very serious to execute the same but non serious efforts can not afford to make a SSS and even a media managed image can not make SSS because a good amount of fund incurred in the same.

Another serious harm to scientific works is intentionally caused by authorities like vice chancellors or head of the institutions (HOI) who appoint air condition (AC) born and AC survived scientists at institutions in absentia. They have put forward the dangerous theories of bankruptcy which is away from talent and innovative minds. The concept or noble or innovative ideas are born in mind not in AC fitted laboratories, of course AC laboratories are required for biosciences to implement certain conditions based enzymes, biofuluds and so on and so forth. But an unfortunate or grave situation is of show off, I doubt whether the ideas are generated in AC, of course one can sit comfortably in AC fitted laboratories but on research front it is debatable and needs good amount of discussion by real researchers. It is different issue that immunity level is degrading day by day due to patting and shaking hands with luxuries like AC and hot air blowers as per weather conditions. The cozy way of life is dominated by 15% of the population or the elites, the real budding scientists are born in natural conditions as the latter do support a natural growth and development of mind which is the sources of thoughts and ideas.

Graham Bell sitting in his hut at Boston, USA developed a telephonic system and Jams Watt a poor villager used to travel from his village to town by horse cart. The owner of the horse cart used to hit the horse strongly and mercilessly with a whip after every hit of the whip the horse used to get hurt much. This event hurt the mind of the young Watt and he decided to develop a cart without horse and hence he found the solution of his natural desire or the pursuit at kettle when water was being boiled for preparing tea. He wanted energy to pull the cart but the water vapor pushed up the lid of the kettle and he found a energy to run the cart and hence he developed a railway engine. we claim a lot in favor of research but follow the theories, concepts, ideas and combinations developed a century ago by talented scientists in a very odd circumstances how many of really contributions are put forward currently.

This is to bring to a notice of concerned that currently focus is to save resources to cop up needs of growing population and different combinations of thoughts. In this direction Survismeter, Econoburette and Visionmeter are the remarkable contributions to science and technology as they serve the three fundamental purposes of the society or the users. The purposes are resource and time saving, and equality among disabled section of society. The survismeter is 4-in-1 instrument to measure surface tension, interfacial tension (IFT) of immiscible liquid phases, wetting coefficients, friccohesity and viscosity simultaneously with 95% saving. Econoburette too saves the 90% resources and user’s time along deletion of pipetting action for a liquid with mouth of users which causes serious harm to the innocent children especially of 10th or 12th standard students. The inhalation of a liquid could be avoided but the fumes of an operational liquid do enter our digestive tract through ordinary pipette. Visionmeter serves the critical social cause, it is well known fact that for dreaming and thinking is an extreme devotion and a concentration is required which is obtained by isolating oneself from earthly things. For this reason the simple way is to close the eyes and concentrate. The same concept is used for working of the visiometer; it is for visually challenged persons who would enter science and technology to dream innovative ideas. This historic landmark is at world level that visually challenged will learn science and technology.

Semi home made servo has extreme jitter. Need tips on resolution.?

Sub-Micro Hitec servo PC board (HS-56HB rated at 4.8-6v), with 4.8v input to 3 pole servo motor from a slightly bigger servo and pot-meter from an X-Mods RC vehicle. Soldered all and works to some degree with a TX and RX but very very sensitive and jitters like mad! When the TX is turned off and the RX is on the servo stops jittering but rests to one extreme. I tried the pot from the micro servo and a bit less sensitive but still jitters off the charts! I also tried to swap the two power poles on the motor oposite but the servo then just moved to one extreme. I also tried a few different caps and resistors I had from 540 size motor rebuilding but either no help or same as no power. I'm stumped. Thanks for any help!!

When a signal comes from the TX to shift the position of the servo it moves to the precalibrated point. That point needs some space to prevent it from jittering. What's happening is the servo is overshooting the "low" limit and hitting the "high" limit which is causing it to "jitter" between the two points. This usually happens because of inertia in the servo motor and the gearing being too high.

Increase the width of the stop point or gear your servo motor a little lower.
