Component and Motor Shops at Lamington Road Mumbai:

Following are some good shops. There are too many for general components, but these have their specialties, mentioned below.

All shops marked with * are useful & rest are just shown for reference. The map is not to scale. Small roads attach to the path shown at many points, but have not been shown. (If any shop has been removed, please let me know. I haven't been to lamington since an year.)

Legend	Shop Name	Good For	Comments
*2	Bombay Electronics	DC & Stepper motors, DC geared motors	Owned by a bit rude Sardarji. But has maximum variety of Motors. Geared motors are most popular. Sometimes he also has high-quality imported geared motors.
*3	Music Masters	Variety of Limit Switches, Leaf Switches, PCB mount relays, Spring Loaded Switches, Displays	The Spring-loaded switches are very useful to make a joystick like control-box for manually controlled robots (usually in level 1-2 contests of Yantriki).
*4	Gala Electronics	All electronic components	(on first Floor)
*5	Battery Shop	Variety of batteries, of different Voltages, and Current ratings (rechargeable etc.), imported too.	Another a bit rude fellow. But he can suggest good batteries if you specify your Voltage/current , size and rechargeable etc. (small tapri shop. You can find batteries all over the lamington road. But if you are looking for variety, this is the person.)
*6	Niki Semiconductor	ICs, Microcontrollers, Memories	One of the best source of various high-end ICs and Microcontrollers which you may not get elsewhere.

The right turn somewhere ahead from the main road, as shown,leads to the Automotive parts Market. There you could buy, Windshield Wiper Motors (of Autorickshaw) which have been modified to rotate fully. These motors could be used in Big Powerful robot drives. But in that market they are called "Servo Motor". Hence use this term when asking for it. (usually Rs. 350-450), Black in color. Though, of-course, scientifically it is not a servo-motor. And moreover, it is a current hogging and electrically very noisy motor.

Photo-Plot or Film Making for PCB:

Image Photoplots, 2nd floor, L Block, B-Building, Satam Industrial estate
(near Bank of Baroda), Chakala, Mumbai
email id: cdimage[att]vsnl.com (send your .brd files directly)
phone no,s : 8374479, 8347896
This is really a nice guy. He also knows many PCB makers. He has good contacts with Balaji Hertz PCB maker. Take Balaji's address and phone number from him.

Before making the films ask your PCB maker if they will need Negative of Positive type films.

PCB Making:

Quick making in EE dept IITB only. (But not for bulk. Running cost to dept. is VERY VERY high, because the machine uses CNC-milling technique to make a PCB. Hence PCBs for non-departmental work might not be allowed.). (in this case, of-course, Photo-Plot would not be required.) . There will not be any screen-printing, and no-green paint.
Balaji Hertz, (best option for PCB making). Andheri, Mumbai
really low cost, and quick enough. Get his phone number from Image Photoplots (listed above) coz I lost it. If you intend to get the PCB made by Balaji, tell Image Photoplots that, and they will make the right film set for him (positive or negative).
Wintech (for PCB fabrication): 47/1, Mittal Industrial estate, Andheri Kurla Road, Marol, Andheri (E), Mumbai
Office: 8506349
Res: 8360885
"He took around 5-6 days for us (for fabrication of 5 PCBs in all, from the photoplots), but if u have a single piece, he might do it in 2-3 days. The proprieter Mr. Wilkie Fernandes is a pretty nice guy" said one IITian. But he doesn't like impatient people! esp. IITians. so beware!
