Helloss!!
Our problem is that our regulator is in a habit of burning..
The regulator is connected to max232 and the microcontroller Atmega128.. We have connected two capacitors of 470uF..
We have changed the burnt regulator time and again but we dont know where the real problem lies..
Kindly...

Hi all,
we have decided to chose GSM/GPRS module "SIM900D"..Now we have confusion regarding the selection of GPS module..Our supervisor is saying that Holux GR-89 is good enough for us but you people are suggesting some other modules..What are the problems we will be facing using the said...
hey embedsys!
Actually we dont knw anything abt the project..and if we are using SIM900D or Holux GR-89 then which is the suitable microcontroller for it..And kindly tell us that whethr TCP/IP stack is built-in these modules or not??And we have studied alot abt this project but have no idea...
hi embedsys!
i m working on the project "vehicle tracking using GPS and GSM/GPRS"... i m facing problems in chosing a suitable module..we have studied research papers regarding GM862-GPS and found it very relevant to our project but it is very expensive.
Second problem is whether tcp/ip...
hello!!! i have selected this project as recommended by you bt i am facing many problems regarding the selection of suitable module.we have searched a module which is using usb port instead of serial port and it is much cheaper than others but the problem is that we have studied everything...
