hi everyone... i've noticed that this website gives more importance to planes and helis... anyways,im from kolkata... was interested in this and came upon this resourceful site. i feel i should make a car myself to better understand it's working,rather than buying a readymade one...although the latter option is cheaper! anyone has any idea about making the circuit board etc...

I had people complain multiples times that this site/forum has too much talk about cars !      Go figure !

Anyways, you have to make your intentions very clear so that people can assist you

Are you planning to build a radio controlled car, or one what is with wired control ?  Radio controlled would add significant complexity.  You cannot make general statements, and expect people to hand-hold you starting from scratch. So read up relevant material here and on other forums, and ask specific questions.  For example, you may ask how I can build a speed controller ?  Or how do I control the movement of a servo ?  I hope you get the idea.

Please note that I am not trying to discourage you at all.  Just guiding you to ask the right questions, so that everyone here can attempt to help you

There are threads here about people doing DIY stuff with cars.

http://www.rcindia.org/cars/anyone-into-micro-rc-car-building/
http://www.rcindia.org/self-designed-diy-and-college-projects/solar-powered-vehicle/

I am sure there are other threads also that can be useful to you... but you have to break your project down into pieces, and take a step-by-step approach.  The word "PCB" alone is too vague.

hello anwar... well you rightly pointed out the weak points. no problem. for starts,im a commerce student in a reputed college... i took science till tenth then shifted to commerce... a decision which was not mine. anyways,i do have basic knowledge of electronics and making things,the rest i learn from the net and have been doing weeks of research before stumbling upon this site...

i have also consulted my engineering student friends on this... so... im not a techie but i am very interested in this... and also to promote this in the area where i live since most are unaware of rc hobbies...

getting back to  my query,i want to clarify that instead of doing things the easy way and 'buying' a rc toy,it would be more fun and educational to build and assemble it...that's why i wanted answers... any idea where to get started? once again anwar... thanks...

Hey you dont have to be an enginner or anything All you need is interest. I would suggest making a non propotional rc first. All you need is a few elect components , motor , donor toy for wheels,chassis etc.

I guess we need to start from the basics.  The fundamental question is, "what do you want the PCB to do in the car" ?  What are its intended functions ?  And the answer has to be more detailed than to "run a car"

first thing RTR are expensives than kits though cheaper than self made models.
Making a self made model is good for only those who can benefit from it as a tech project.
If you really want to build it yourself so that you can learn how it works i would highly recommend you to please buy a self building kit which will be a lot more cheaper and better in almost all aspects.

any idea how much will a low cost DIY should cost? im more into heli's than cars... thanks for the info arpit...i guess a kit would be the first step...
