Custom SPice? Just
ask!
"SPice" is the name we use for special function
"daughter boards" that plug into our regular controllers. We have
off the shelf SPice boards for a range of special functions, such as
water level detection or AC current measurement. Sometimes your
control project just needs that special "Touch of SPice" to get off
the ground.
SPice boards are small, generally simple for us
to design, and frequently don't contain particularly expensive
components. It's not so much about the sophistication of what they
do as the simple fact that we design some circuitry to do something
that's not always readily available off the shelf. We make the
seemingly inaccessible available to you.
But
there's more! Because the SPice idea is so simple, it makes it
feasible for us to make you a custom SPice board at an cost you can
afford in quantities as low as 15 to 20 units. While we can't do
everything imaginable, we can do special purpose input signal
interfaces and special output drivers. Think in terms of converting
ordinary digital or analog I/O into special purpose
pins.
So,
if you have a project that is stalled because you are stuck for a
weird kind of interface, ask us. We may be able to
help.

The First Blinking
LED
It doesn't matter how many years I spend in this
industry, I still get a buzz out of that first blinking LED on a new
board or program. It's the embedded controls equivalent of "Hello
world" in C on big computers. It's the first sign of life in your
new baby, and with it comes the reassurance that it's all going to
be OK in the end. I have yet to meet an embedded controls engineer
who won't admit s/he gets a buzz out of the first blinking LED.
But there is a little more to it than just the buzz of
the FBL. The FBL is just one tiny step, but a hugely important one.
By aiming for that tiny step we recognize that great things can be
achieved if only we have the wisdom to plan for one small step at a
time. Breaking the task down into a series of small steps, and
making sure each one is completed before tackling the next one, is
the key to success.
Tell me your take on the FBL! |

The power of
minus
We all google for the things we want. But do you ever
google for the things you don't want? Google has a search feature
that allows you to exclude all search results that contain
a given term. You do this by placing a minus sign in front of a
word.
For
example, if I google for tiger woods I get a whole heap of results
concerning recent unfortunate events. But suppose I am more
interested in the man, not his games. So I try tiger woods -golf. This gets rid of a lot of
sports stories. It narrows the search down, but it is now
clearly polluted by recent events. So I simply scan the summaries,
pick out common words that signal the pollution and add them to the
negative terms. Finally, I wind up with a search for
tiger woods -affair -woman -uchitel -accident
-transgressions -crash -wife. Now I have filtered out almost
everything concerning recent events, and I see a picture of a man
who is a role model, has a church named after him, etc., etc. In
short, I have dug through the noise of recent events and found the
underlying information.
I find
this technique useful when whatever I am looking for shares a name
with something in a completely different field. Example.
Give it a try next time a google search returns a lot of
noise. |
