Re: Basic Basic Question
Ok so the cap can provide the 500 Amps based on the voltage output through the resistor.<p>
So how high would the power rating on the resistor have to be? I calculated 6000 Watts.<p>Is that available??<p>bob

Basic Basic Question
I have a very basic capcitor question.<p>I know that a cap stores voltage and passes current. I'd like to know how a car audio cap, 1 Farad provides some 500 Amps to the system from a 14.4 V Battery/Alternator.<p>I'm probably missing somthing really simple here.....<p>thanks<p>bob

Best Interface Option
Hey,<p>I am looking to interface a called ID decoder chip to my computer. The chip's output is serial data, 1200 baud, 1 stop, 8 data for a total of 10 bits. Should i go into the serial port directly with this or convert it parallel with a UART and go to the parallel? I want to use VB to record the ...

Re: Electret Microphone Element
Ok, i have my meter connected to the side of the cap not connected to the mic, and ground and the meter reads zero. <p>I guess the cap does not pass the dc.

Electret Microphone Element
Hey guys<p>I need help. How on earth does the electret mic work? I have it connected as in the diagram that accompanies it, but on monitoring the output voltage, it doesn't change. How do i make this work in a circuit??<p>Here is the diagram <blockquote><font size="1" face="Verdana, H...

Re: Choosing a Microcontroller
Colin,<p>The bits are <p>300 1's and 0's
200 1's
data (10 bits)
7 1's and 0's this is data as well but i dont need it

Re: Choosing a Microcontroller
Also, how would you code an ignore function? Is there an ignore function for all families of pics or just the higher memory ones?<p>For instance, does the 16f84 have an ignore function?

Re: Electric Vehicles
How about using all four wheels as a generator to generate or to recharge the batteries?

Re: Choosing a Microcontroller
Ok....the data is 8 eight binary bits, so i suppose 1 byte?<p>The first 300 bits that are to be ignored are the same all the time. Could this allow the PIC to get ready? <p>What is a circular buffer?

Choosing a Microcontroller
Hey guys,<p>Can you please suggest a pic (preferably) or a microcontroller that can loosly do the following.<p>Have about 325 bits of information sent serially to it. The unit must ignore the first 310 bits, record the next eight and ignore the last 7 bits. The eight recorded bits must be compared t...

16F84
Hey guys is the 16F84 chip powerful enough to take in 8 bits of data and compare it to information from RAM and set one of its pins low or high if the data matches?<p>If not, what do you recommend?

Video Amp
Hey anybody have a good schmatic for a video amplifier? I have a cable splitter in my house and it is split many times over long distances. I need to amplify the signal for one room. It is NOT the new digital cable systems. Thanks

Re: SBS
Wow you guys certainly know your stuff. How about the SUS then.....anywho know much about that? I cant find the schmatic symbol anywhere.<p>Anybody know of any good thyristor books or resources?<p>[ November 25, 2002: Message edited by: newguy ]</p>
