    URGENT : Please help on 40Khz oscillator

    Also if possible also suggest a scheme for the amplitude of the sinusoid to be around 22 to 28 Volt peak-to-peak. Thanks in advance.

    URGENT : Please help on 40Khz oscillator

    Hi, Please could anyone provide a ckt. diagram for a 40 Khz sinusoidal oscillator. A circuit using a IC will also do.             OR A circuit using discrete components like transistors etc will also do. In short any 40Khz sinusoidal oscillator design is welcome. Please provide any or as...

    Please help on odd reference voltages

    cant construct a pot ... sorry instead trying to find standard resistor values to satisfy the combination-ratio ... trying hard to find them ... thanks for the help guys

    Please provide "Art-Work" or PCB Design Software.

    The link given for EAGLE provides a "LITE EDITION" which doesn't allow auto routing. The scale provided in ARES is not valid for actual artwork ... it linked as per CNC ratings

    Please help on odd reference voltages

    Thanks, will try... have any specific pot for suggestion? Will the pot give required accuracy? I dont think stability would be a factor because after all its the ratio that counts ... temperature coefficients would get cancelled ... hence insensitive to temp. changes?

    Please help on odd reference voltages

    Please help me with the (schematic) design of reference vtgs. of +2.65V and +3.673V. Accuracy and stability and stability are the most important criterion as they will be fed as analog ref. vtgs to PIC .

    gramo, Proteus is great but it ain't free. I had bought the ISIS PROFESSIONAL and ARES suites ..... the simulations are still working but the licence for the ARES has expired.

    Thanks for the support. Please could you also suggest a suitable site from where I could download such "newer cad" software-programs. It would be of great help.

    Thanks for the suggestion mvs, but pcb123 was a bit tough especially on the "routing" part. Is there a software that can provide facility for auto-routing ? I had downloaded Dip-Trace but it was trial version and is now expired.

    Site Accessing Trouble

    Hi, Sometimes when I try to access this site it just doesn't open. It gives errors like invalid address or check network status or it just takes eternity to open ..... literally! Why does this happen ??? and this does not happen with anyother site I visit.

    What is artwork? (Is it same as PCB designing?) Which is the best freely available software on internet for pcb design / art work? Even a trial version (that'll work for few days) will do ... but it must have sufficient utilities. Also which is easy to learn and use in shortest possible time...

    Protecting the motor

    Thanks for your help guys, but a polyswitch aint feasible bcos .... actually it isn't available in the local market and ordering it from net isn't possible. But the idea, you all suggested, of using the rise in current during overload to trigger a ckt. break and again close ckt. after certain...

    Protecting the motor

    What are they? Where do I connect them? The motor has only two wires coming out from it.
