  1. HI MP, I did it by OP_AMP . Is there any IC that it can do all of this by own? Thank you,
  2. HI ALL, I have a device that The voltage of input is 0 (v) till 12.5 (v) & current output is 4-20 ma. So I need a schematic of resistor to voltage convertor so that in spite of 0 (ohm) it has 0 (v) & in spite of 900 (ohm) , it has 12.5 (v) . THANK YOU, abt4s
  3. Hi. I need a schematic and pcb of computer power supply that it should have 400 or 450 watt . thank you
  4. Hi. I need a schematic for transmit & receive data that it should be wireless . Frequency is not very important but it is better that the frequency won't be in FM band. baud rate is among 600 till 19200 and I am going to use data from IC in AVR series or RS232 email :[email protected]
  5. hi my friendes thank for your replies dear Staigen . i need radio , a simple board and range should be 400m or upper. dear balong . this is my email address ([email protected]) , would you please send your circuit to me ?
  6. Thank you Staigen Frequency is not very important but it is better that the frequency won't be in FM band. baud rate is among 600 till 9600 and I am going to use data from IC in AVR series. ;)
