  • I looked at the Sparkfun meter picture at the top of this post before reading about the problem. It didn't make me think of Fluke, and I've been using Fluke meters for 30 years. Simple as that.

    But then, one of my Fluke multimeters is a beige 8840 bench meter. Another is a gray/brown model 75 handheld. Another is a greenish cased 88XX bench meter. For Fluke to now claim ownership of the color yellow is ludicrous. Are they going to claim the beige, and grey/brown, and green as well? When will they try to claim blue and pink?

    I grow weary of corporations attempting to claim so much as theirs alone. When they try to claim colors, they go too far.

  • With the obvious enormous differences between analog and digital devices, a standardized datasheet makes no sense.<br />
    <br />
    Not to mention the fact that specialized and hybrid devices can need 50 or 100 pages of datasheet to describe their operation.<br />
    <br />
    Do we really want to make all datasheets a hundred pages long just to standardize them? Or do we want to leave out critical info in order to keep everything standardized.<br />
    <br />
    Who cares what the noise figure is of an LED? Who wants to know the power handling capability or rise time of a thermistor?<br />
    <br />
    What we're really in need of is standardization of datasheets for "similar" types of components.<br />
    <br />
    While the government and military procurement contracts go a long way to create some sort of standardization of specs - still more industry standards committee meetings are in order to create more common component definitions. Unfortunately, such meetings cost money and may not be in the best interests of some of the players.<br />
    <br />
    I think it best that we not count on corporations to do the job, and either learn to read and understand what is written, or create our own "standards" and rewrite the component specifications of others as a public service.<br />
    <br />
    Otherwise, it ain't gonna happen.

  • The copper layer could be for thermal dissipation and also for electrical noise suppression. In that case it might be where the extra wire attaches.
    Look at old ceramic uP's and you'll find a grounded gold coating on top of a lot of the chips.

No public wish lists :(
