IC4, MAX232, is used to connect to the PC by serial port. This connection is useful for debugging and controlling the robot by issuing the command through the keyboard of the PC. Though in real autonomous run of the robot, this connection would be taken off. Either give the Gerber files to your PCB maker. (you can email the Gerber files directly to Image & co. , and call them

on 28347898. They will make the "films or photoplots" of your pcb, which you`ll give to any PCB maker. ) Get the Silkscreen and printing of labels also done on the PCB if you can spend more. (Approx cost of photoplots with legends Rs. 400-450 at Image). Or print the Top and Bottom layer PDF files on a 1200 dpi laser printer, and give the printout to your PCB Film maker or PCB maker directly. I do not recommend this method as the print quality may not be good, and tracks may get shorted. But this is the last resort usually of the Non-Metro residents. Getting the Film made from a printout (the second method above) is usually less expensive but the quality may not be proper. Your Film-maker will tell you if he can make it from the printout you`ll give to him after looking at it. (approx cost is 25paise/cmsq). Getting the Film made from the Gerber File is more expensive, but the quality is best. It would be better if many friends share a common film`s cost. (In IIT, one of the Yantriki coordinators may get many PCBs made in bunch after finding out the demand, as was done a few years ago). IITan`s can also try getting their complete PCB done in the PCB facility of EE dept for free. But that pcb would not have component names printed on it. Moreover the dept. facility may not allow too many PCBs of the same type because the tool there is much more expensive in its running cost. IMPORTANT: Tell the PCB maker to drill, 0. 8mm holes...
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.....
