Something for the real electronic shacker

  1. I just found THE neatest web site for electronics designers in 10 years of
    surfing the net. The National Simiconductor Webench
    http://www.national.com/appinfo/power/webench/

    After you sign up you pick an application area, enter what the inputs will
    be and what outputs you want and it suggest the components which you can
    adjust as needed, builds a schematic, runs simulations on it, creates a BOM,
    prices it out and then with a click you can order a kit complete with all
    parts and a prototype PCB designed for the selected circuit! It also saves
    your designs and simulations so you can come back and adjust them or order
    more.

    It is all SMD technology, no through hole stuff, but that is OK by me. I'm
    getting pretty good with my little toaster oven and a pair of +5 readers.

    I just designed a 12V to 28V up converter in SMT components to drive a
    pressure transducer for the watermaker. In about 15 minutes I designed,
    tested and ordered the parts and the price was $23 including shipping. I
    couldn't get custom a PCB alone for that price. All that is left for me to
    do is to paste'm and bake'em. (And hope it works, but I do that with every
    project.) :)

    I'm building a 45' cutter in strip/composite. Watch my progress (or lack
    there of) at: http://www.rutuonline.com

    I discovered it a few months ago. Very handy. Unfortunately I was
    designing a boost-buck converter and it couldn;t handle it. Not a
    fault of the tool, there is no controller that can handle it directly. Now
    the
    challenge is to get a PC layout that will keep the noise from
    swamping your radios :)

    There are other similar tools from other manufacturers. I found one
    to deisgn amplifiers the other day. Analog Devices I think.

  3. Agree completely. I gave Webench a Product of the Year award in
    Electronic Products mag the year is was introduced. It was well
    deserved. That must be 7 or 8 years ago at least.

    an axe head come through the door on your right.

    Thanks, Glenn. I sent this to the engineers over at Navy SPAWAR I know,
    and some other engineers I know....(c;

    Maybe now there power supplies won't have 300 hours MTBF...(c;
