Ben is doing long term load testing of rubber samples at different
temperatures. He is a mechanical engineer and will design the
machanical portion of a machine that takes 4 rubber samples, each with
their own load cell (4-20mA) inside an insulated box and heats them to
a user supplied temperature(Room temp to 400F). It then logs the
temperature and load cell values for each sample every hour for a user
specified time (24 to 5,000 hours).
He wants to use a keypad and two-line character LCD for user input,
and have safety interlocks for the insulated housing. The data should
be collected to a memory card and/or computer connected to the device.
Ben would like to have someone design the circuitboard, firmware, and
all circuitry necessary to:
* Handle several 250V heaters
* Handle user I/O (keypad, LCD)
* Read, maintain, and log temperature (thermocouple)
* Read and log load cells
* Handle safety interlock (can't open box until cool, won't heat if open)
* Handle memory card I/O
* Handle computer I/O
* Power load cells (10V excitation) and other circuitry as needed
* Handle cooling fan to prevent exterior of case becoming too hot
He wants to start off with a four sample design. Ultimately he would
like to expand it to 16 samples, and eventually include testing at
temperatures below room temperature.
Ben is intending to have 20 made initially, with the possibility of
larger runs up to 100 at a time, and is interested in a short
development time (1 month or so) to delivery of a prototype.
Please contact Ben directly if you are interested (contact information
at the top). I wrote this summary based on our phone conversation and
a document he sent me which you can request directly from him.

Just an idea: Sort of _FREELANCE_ job site based on PICList.
I've got some ASP.NET / MS SQL server experience and I think, I can
develop code for the site on my own. That is I can invest my time as
developer in the project.
I'd see four players here (I'm open to discussion):
- me as code developer;
- James as list owner;
- some person representing EE spirit of the list, gathering and
generating ideas, say Olin;
- the board of top list EE contributors (including RM);
I can't work full time now, but I hope I could spend considerable
amount of time on the project. At the beginning the host could be some
free ASP.NET / SQL server host, perhaps http://europe.webmatrixhosting.net
Why not try it, nobody lose anything, but time on discussion. Anyway
that's much better than wasting time on lengthy political discussions.
The project should not be "open source". The code besides me is meant
to be available to James and Olin. Should the project ever make a
profit, the profit will be distributed between mentioned 4 players.
I'd suggest that the site should not be purely job dedicated site, but
also should be free EE educational and consulting site (free to some
reasonable extent). The free consulting activity of each EE developer
should be tracked down and ranked up to let a potential customer
better make his mind about who's the person he is considering for his
project.
The knowledge base should also be maintained to ease the consulting
and developing process. Contributions to the knowledge base should
contain contributor's Id to increase contributor's points when used.

And what's the advantage over other similar sites out there? The Unique
Selling Proposition?

I didn't hear other similar sites to offer free membership to
PICListers or to have educational payload with based on it ranking
system or are open to discussions what rules they should be based on.

I don't really understand what you are proposing. I'm willing to explore
means of getting more exposure and ultimately more customers, but I'm not
getting what this web site will do. I don't think you are just listing
people with particular skills since that wouldn't require more than a little
HTML, and that wouldn't be different from lots of other sites anyway. You
seem to have a bigger idea in mind, but sorry, I'm not getting it.

Similar to what? I don't have a clue what we are talking about...
Are we talking about a site to bring together consultants with people who
need to hire them?

Wow, I never realized that the distance between PIC planet and ASP.NET
planet is that big.
Thanks James, Spehro, Olin for the great lesson.
Give me some time to express the idea more clearly.

I don't think that this distance is the problem. I don't think that it
matters (to the user) whether you write the active portion of a dynamic
site in ASP.NET, ASP, PHP, Python, JSP, C, PIC assembler, whatever... as
long as standard, readable HTML comes out :)
But it seems nobody understands what exactly you want to come out. That's
not a question of technology (of implementation), but of content/concept.
