dis is the diagram... hope u can help me guys!

about d park aid.. i cant seem to find 1micro Farad capacitor needed for the circuit....its not available... i was wondeing what value of a capacitor would be most efficiently be used as a substitute.. plz help.

another proposal that we do have works just like a homing ( did i spell it right??) ;D device.. we wish to implement it to our university to eliminate the need for the checker to go room by room to see if the instructor is in their room in a given time.. we do have a chance to ask our instructor about it, he told us that we need 1. a transmitter ( to be placed in ID "where our group want to put it") that transmit a certain frequency. 2. a receiver/ transmitter place inside a room to receive the transmitted signal, then transmit it again to the receiver in the basestation 3. a receiver in the base station i know that we will need a micro controller to be able to interface the receiver to the PC. d problem is i dunno what kind of transmitter are we going to use to have a unique frequency per person to help them distinguish their identity. would a low power transmitter do the job? we need somthing that transmit frequency with a room size range so that it will not interfere with the other room where the same device is installed.. pls help.

good am! i was wondering if it would be possible for a telephone ( the one we are using at home) to have an additional feature like voice dialling?? what do you think guys? any idea would be welcome..

im new in this forum.. i was wondering to know more about the voice activated locking device.. ive seen the circuit but did someone already crack it ( i mean from the picture to the schematic diagram???) pls help...

gud aftrenoon. im a 5th year ECE stud. im enrolled in project study, i chose the economical pump controller to be one of the proposed topic of our group, d problem is, i dunno how the circuit was made.. i believe that there are some computations before we arrive in the circuit as shown in the site. please help me..
