Hello Everyone,
I am consisdering building an electronic weather station which will basically consist of two main blocks, one of which will contain all of the nessesery instruments and can be be placed in a remote location, this will then radio back data to another block attached to a PC where...
Hello
Me again about my ultrasonic range finder
Just wondering what would be the best value of capacitors to use when decoupling the supply and maybe if reqired across the vcc and gnd of the reciever amplifier. Had many problem a the first attepmt on building the design on coper strip (works...
Hello,
I'm building an ultrasonic tape measure and am having trouble obtaining a distance greater than 1 metre. I have an idea to try and get a greater distance: I think that maybe I am losing a lot of my transmitting power because the output impedance of my oscillator is not matched well...
:cry:
I am currently developing an ultrsonic measuring tape. I am having one major problem and that it getting distance (ie the reciever picking up the transmitted pulse). At the moment with no amplification on the Transmitter ( ie o/p of 4047 BE oscillator being fed directly into transducer)...
