I was intrigued while playing the motion games on Nokia 5800. I was thrilled, how I could control the racing car by only tilting the phone. I used to drea

m of making this same car in the real world. Hercules is the name given to my motion controlled robot because of its immense torque and speed. The robot is controlled by an android phone through bluetooth. The advantage of using an android phone to control the robot, is that I can use any android phone to control it and am not confined to using only one controller for the robot. The use of an android phone as a controller, significantly reduces the cost of the project, since money is not spent in building a controller for the robot. The Hercules was built for the 2012 Indian Institute of Technology, Mumbai`s IIT Techfest ( Asia`s largest tech festival ). The objective was to build a motion controlled robot that could race around an obstacle track. The principle of divide and rule can be applied in every aspect of our life. This simple principle is also applied to this circuit. The circuit is divided into different boxes. This modular design makes it easy to maintain and troubleshoot the circuit. If some component burns off during the competition or when it is being run, then the corresponding module can be replaced quickly. 1. Cut the PCB using a hacksaw into 4 parts as follows: a) 2 nos. of PCB each having eight holes in length and three holes in breadth and b) 2 nos. of PCB each having six holes in length and three holes in breadth; which after assembling should look like the first picture. 3. Solder wires (approx 4...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
