Circuit
the circuit is quit easy and all you have to do is fix all the components according to circuit. better if you place the LDRs separate so that it is easy to place.
Body
i use dc geared motor from CD drive. now when you have crosschecked the circuit you can switch on the power supply and see it work. make sure that it runs straight.
Some Problems and Its Ready
the only problem is that it is hard to change the direction { it will but it will take time} but you can play with it at night by focussing a torch at photocells } , also you can attach a multicolor led and it would look great.
now its complete ! have fun. :) ;)
