    go kart lap timer

    I am no expert so take my advice with a grain of salt. But couldn't you use a coil of wire to bring the magnetic field , in a sense, closer to the sensor? Isn't this how a current measuring device works. a magnetic field effects a coil of wire and the hall sensor is connected to the coil to...

    Wind turbine project, wiring, etc.

    an alternator only produces AC, but they have built in rectifier diodes. Removing of the rectifier will give you straight AC, but as steve says the voltage will fluctuate with varying loads. That is why most people rectify the AC and let the battery clamp the voltage. They don't do these...

    About sound reactive led's with TIP31C

    Because you will never get the full 12V across the LED strip when wired in the schematic you posted. How much dimmer are the LED's when driven in this manner? Does the LED strip have a built in resistor?

    Wind turbine project, wiring, etc.

    To begin with, most wind turbines I seen that are manufactured don't like high wind speeds. Most will start to brake around 35MPH. So you will need to make a very rugged turbine which could be costly. The best type of motors for a turbine are PMA (permanent magnet alternators) One or two 120V...

    if the leads are the same length, look at the two plates inside the bulb, the larger plate is the cathode I do believe. You can also check it with a meter if you have one...

    i need help very badly

    Voltage divider in a filter?

    are you allowed to set the date back after installation or is that just the year that is the same as 2012 as far as the week is concerned?

    how to write c code for motor

    to add to what harald has said. Also, I take it you are using a AVR chip, Or don't you have a clue? DDRA = 0x00; //set all porta to input DDRB = 0xFF; //set all portb to output sensor = 0; while(1) //infinite loop because it is always true { sensor = PORTA & 0b00000100; if(sensor...

    Wanted: PIC programmer.

    Now I am wondering what I want to do. I was thinking of just buying the programmer, but the development board would be nice in that I don't have to buy a lot of extras just to get started. One quick question, what does the ICSP port accomplish?

    Just worked out how to rid cancer forever...

    Well I do really enjoy his over enthusiastic mind. But after losing both my parents at a young age to the disease, I don't personally believe that cancer can be solved by only letting certain couples mate. It seems completely irrelevant, for me until proven otherwise, genetics may only play a...

    Wanted: PIC programmer.

    Do they still have the debugging capabilities? Recommend a USB programmer! I would pay for something if I knew how well it worked. Not knowing is what keeps me from spending money on a device that may or may not be what I want. Can I use any of these programmers with mikroC or MPLAB or do they...

    MAKE: Electronics Ex. 10 Help Needed

    Well hate to break it to you, but the last few photos are no different then the first ones you posted. Where is the switch? You still have the resistor on the base of the transistor connected to nothing. Did you post the wrong pictures?
