Circuit Design help
I need help designing a circuit. I can build just about anything as long as I have something to build off of. My problem is I'm not very strong at designing the circuits.
I'm pretty sure what I need is an Oscillator circuit running at 125kHz. What it is for is re-pairing Tire Pressure Monitor Sensors on my 2004 Silverado. The description that I found states that "The sensor is stimulated with low frequency magnetic field (125kHz, may or may not be modulated). This will cause the sensor to transmit." It doesn't need to be powerful. The field really only needs to extend about 6".
The sensors can also be paired by letting air out of the tires, but it would be much nicer (and more reliable) if I could build a tool to force the sensor to pair up.
Does someone have a good circuit I could use for this function?
Thanks in advance,
Dave
