The 3Dvarius is an electric violin created by 3D printing technology and based on the model of a real Stradivarius violin. Printed as a single piece, the 3Dvarius violin departs from traditional musical instrument production technology.

Combining the precision and power of 3D-printing with ancient violin-making skills, its innovative design, in the service of violinist, marks a further step toward the perfect symbiosis between musician and instrument.

The 3Dvarius was born digitally in 2012, in Laurent Bernadac’s mind, the violinist and engineer who conceived it. Laurent wanted to create an electric violin which could fulfill all the needs of a classical musician. His goal was to create an electric violin in perfect symbiosis with the musician.

He created 2 ...

My Proposed Project:
5/8" Drive Hand Ratchet system with a 3 piece 50" long Telescopic Handle with a group of Hand/Impact Sockets.

This system is to allow a mechanic tighten or loosen bolts (or fasteners if no bolts exist) easily. The system will compliment the 1/4" Dr, a 3/8" Dr, a 1/2" Dr and the 3/4" Drive Ratcheting systems.

5/8" drive system will fall between 1/2" & 3/4" drive systems. A 1/2" drive chrome sockets above 3/4" cannot tighten or loosen with the 1/2" drive ratchet system available because the handle length is not long enough. A 5/8" drive system with Black oxide sockets from 7/8" up to 2" will give a mechanic a chance ...

Bicycle is used as mainly short distance carrier. Speed of a cycle generally 15-20 km/h, if we pedal it comfortably. We can get more speed by fitting big-size front chain ring (with increase number of teeth of ring) or increasing rate of rotation. But both are laborious for human. To get high speed without hard labor I have thought of an innovative idea.

In my innovation we can get more than double speed by fitting double size front chain ring, but do not need extra manpower. For it two chain ring to be fitted at the two side of crank set (where crank arm is fitted) and two rear free (rear chain ring /cassette ) to be fitted ...

Lithos Motors is an automobile startup that focuses on providing innovative, clean energy transportation for urban commuters.

At Lithos Motors, we aim at changing the way India commutes. The world will shift to clean and green transportation solution in coming years, and we aim to act as a catalyst for this journey. Also due to increasing use of public transport, future will be of short distance travelling and we aim to tap it. We have designed and manufactured a  compact, foldable, lightweight, ultra-portable, electric ...

Internal combustion engine is the most efficient and economical on-road power machinery and maintains the dominant role on the market. Among them, SI engines occupied a much higher proportion on the light vehicle engine markets than diesel engine. However thermal efficiency of SI engine is not satisfying and ideal, especially at high speed and load operations. Because of exhaust temperature limit, fuel enrichment technology, indicated by air-fuel ratio on figure 1, is required to ensure the proper work of turbine and catalyst, resulting in much fuel lost and emission deterioration shown in figure 2.

Currently, this fuel enrichment regime is not included in the drive cycle assessments, but with the increasingly stringent emission legislation being published, it is ...

Adversaries threaten multiple High Altitude EMP (HEMP) attacks initially sparing human life, crippling power, communications and High Frequency (HF) backup disaster response networks for hours. HEMP is less disruptive between surviving Low Frequency (LF) radio stations. HEMP response networks comprising small two-way low data rate LF relay stations similar to Air Force's retired 1970's Ground Wave Emergency Network are proposed to assure timely damage reports from the field critical to resources management. More, smaller, less expensive stations can also reuse existing HEMP protected HF transceivers.

Size, complexities, costs of LF terminals increase with decreasing frequency and ground wave communications distances decrease with increasing frequency. A sweet spot is currently unoccupied Aeronautical Navigation spectrum between 190 and 198 kHz, ...

Deep frying is not possible by method steam generator boiler. In the present conventional method for deep frying of commercially food manufacture unit, the utensils (vessel) are heated directly over the burner but in my innovative method, the vessel (jacketed kettle) is heated by the circulation (by ¼ H.P. motor pump) of hot oil. Its nobility is its energy efficiency, safety and quality control.

In this method cooking oil is placed into the jacketed kettle and it heated by hot oil (edible oil of 200°c) circulation through pipe line which is made of ‘Teflon’ or any other insulating medium which is heated by immersion heater into an another tank, and it’s temperature is regulated quite bellow of its smoking point. ...

The Clarke-Brayton Engine has the potential for 55% brake thermal efficiency compared to 42% for state-of-the-art conventional diesels, is dramatically more compact than conventional engines of the same power, can burn diesel or natural gas as compression-ignition fuels and is less expensive to manufacture. Two prototypes have been manufactured and tested, the latest of which has demonstrated 45% indicated thermal efficiency, including losses for gas mixing and pumping. The test results have shown a clear path to 59% indicated thermal efficiency.

As shown in the submitted video, the engine is composed of modules of three cylinders – an intake cylinder, a smaller bore combustion cylinder, and an expansion cylinder with the largest bore. Air moves sequentially from intake to ...

Currently ECU is used in cars to increase performance. This MechaSpark ECU is a LOW COST microcontroller based ignition system which increased the power output of engine and REDUCED FUEL consumption. This is can be TUNED to provide various performance modes such as MOUNTAIN-CLIMBING, HEAVY-TRAFFIC, OFF-ROADING, etc. It is much CHEAPER than a conventional ECU and can be incorporated without major modifications in existing bikes. It DOES NOT involve high MANUFACTURING cost. It just needs a hall sensor and timing markings.

It increases PERFORMANCE and reduces FUEL CONSUMPTION there by it is ECO-FRIENDLY. It is fully automated, ROBUST, SAFE, LOW COST and is a READY TO USE ...

A robotic inspection platform (“GeoRover”) is proposed for real-time and remote evaluation of highway culverts, drainage pipes, hillslopes, and other structures or features within a highway maintenance setting. The GeoRover is constructed of low-cost and readily available components for customized inspection purposes which are tailored to typical and specific highway maintenance needs; no expensive machining or elaborate construction and assembly is required, although control software must be written as this is not an off-the-shelf product. The GeoRover and selected onboard devices may be controlled using a standard hobby-grade 6-channel radio controlled (R/C) transmitter/receiver system, with the ability to operate in semi-autonomous mode if so programmed.

The intended applications include: visual inspection of culvert and pipe interiors with a ...
