    Fuel Guage Anti-Sloshing Circuit

    The capacitor approach may or may not work. Most fuel senders actually sink a reasonable amount of current out of the fuel gauge (can't remember now, but it's somewhere between 20 and 100mA). Most gauges are current-driven, not voltage driven, so you may need to reconsider your other circuit...

    How to control the 3-phase brushless dc motor?

    When using BLDC motors in position control applications, adding a dedicated encoder or resolver to the motor output shaft allows you to close the loop around position at whatever resolution you require. -Dean

    suitable motor for electric car

    Given your mention of 'short range', I am assuming that efficiency is not a primary design driver, and thus a brush DC motor will suffice for your application. Check out Advanced DC motors for some good brush-type motors for vehicle application. http://www.adcmotors.com/ Can you provide some...

    64M NVIDIA Geforce3 Ti500 DDR card???

    Simon, If you're looking to buy a card, check out cards based on Nvidia's Quadro/Quadro2/Quadro3 chipset--it's the Geforce/Geforce2/Geforce3 core, but optimized for professional graphics (presumably by improvements in the geometry engine), rather than gaming. If you already own the card, check...

    I was currently troubleshooting a p

    For a temporary fix (until you can track down the mystery load), you can reconfigure the server to begin the shutdown process when the UPS batteries reach 20% State Of Charge or so rather than shutdown immediately after the glitch. It usually takes 5 minutes or less to fully and safely shut...

    Large voice coil driver

    Can anyone give me a quick overview of "Hysteresis Mode Switching", commonly used for driving large voice coils with an H-bridge? I understand that switching frequency changes with error--is this the only difference between this and more conventional PWM control using an H-bridge...

    Large Assemblies

    We're running SW2000 SP13. We run stand alone installations with a single license server. The rationale was to maximize available bandwidth for data, leaving the application local. Understandably, this becomes less feasible as the number of clients (that need to have monthly Service Packs...

    Large Assemblies

    BBJT, Can you provide some details about your current network configuration, and what suggestions your SW consultants have given? We have similar performance problems, and I am eager to try anything to appease our SW design team. Our current network configuration is switched 100Base-TX, full...
