Microcontrollers with housing / case / shell / enclosure ??

edited 2003-04-15 14:16 in General Discussion
I just endured a frustrating WWW search for Pre-Packaged
Microcontrollers of any kind.

The products and projects I found all seem to stop at the BARE
BOARD stage. You 'never' see an enclosed solution. (One project
stuffs a PIC chip inside the end-shell of a DB-9 connector.)
I need a microcontroller complete with a housing or case or shell
or enclosure. I want to buy something, connect any needed part(s) or
cable(s), program the thing, and have a finished commercial unit.
DOES ANYONE MAKE THIS PRODUCT?

Background:
In our commercial application, we need to add a "black box" between
two other devices. On one side it needs to listen and respond to RS-
232 commands according to an established protocol. On the other side
it needs to generate a clock signal and pulse two command signals, as
commanded. (Loads need 5V @ 10mA, so bare TTL is not enough.) We
might only need to make two or three of these, ever.
I could make this black box box using one of many kinds of
microcontroller, from a $2.00 PIC chip to a $1000 SBC.
The problem I encounter is, whichever controller I use, I end up
with a bare chip plus support chips that needs a custom board. Or if
I buy something integrated, I still end up with a bare board that
lacks a case and a power supply. I want to buy something, connect
any needed part(s) or cable(s), program the thing, and have a
finished commerical unit.

Backdoor:
One desperate / hackerly way to find a packaged microcontroller
would be: Buy someone else's complete magic box somewhere, for
example a sprinkler controller. If I can replace the microcontroller
with one that I can program, this is something I could use. Maybe
additional mods are needed, like removing the relays and making the
open-collector drivers available outside instead. But this seems
sloppy as well -- it will still have a little keypad and a display
that I don't need and can't explain.

Fallback:
I found only one maker of pre-packaged generic micro-controllers,
Blue Earth Research. Their stuff costs more, $519 to get started
with an 8051-based controller with optional buffered i/o module and
development kit. $199 to $319 per controller after that. Modifying
a sprinker control could be a lot cheaper, but using a purpose-built
generic unit that comes with development tools has to yield a neater
result, plus a $time savings.

Why not a packaged Stamp?
I suggested that Parallax should consider making a pre-packaged
BASIC-Stamp product. More people would consider using BASIC Stamp,
especially at the commercial end, if there was a pre-packed version.
Take the current top-line Stamp, add a circuit board with selected
support chips, RS-232 connector, and some kluge space for
transistors, relays, optos, whatever. Assemble it with a decent
plastic package and battery-eliminator that plugs in to a power
jack. They could make the battery eliminator optional, even make the
support chips optional (just leave them off the board), all to keep
pricing low and popular.

    Jim,

    One problem is that project needs dictate size, and so it hard to do a "one
    size fits all" box. I have never seen a product such as you describe.

    If you are only making one device, then using a case from a dead piece of
    equipment is the way to go. If the previous device had stuff like a keyboard
    in the way, you can make a faceplate. Covers the old holes, looks nice if
    well done and easy to mount your equipment. Many enclosure have a faceplate
    already, so you can use it as a template for the mounting and make a new
    one.

    Good enclosures can be made from all kinds of stuff. The main power
    controller for my large Tesla coil was built in an old army ammo can.
    Repainted and all the equipment mounted, people always wow it. Nice handles
    and tough. I often take a dead device just because I like the case and plan
    to gut it for one of my projects. Luckily for me, I enjoy the enclosure
    making part. If nothing else it means I am close to done!

    If you are making a bunch of devices, then obviously you have to get the
    enclosures made or find one on the market that works. But if you are making
    a few but not a lot, I think it's a tough nut to crack.

    Hi Dan,

    I have a BasicStamp-PLC that is really just a board with a micro and
    a bunch of connectors.

    I have a couple versions,

    one uses a PIC for it's internal ADC chip, another uses a BS2 with an
    ADC on-board.

    yet another is a BS2 with a buch of plug in connections similar to CD-
    ROM connections.

    as you can imagine, these are small units some require an external
    board to support the parts needed to complete the circuits for
    devices. for instance, if you wanted to monitor a strain gauge or
    load cell or humidity chip, you will need to have that circuit
    seperate.

    I have never put these on a web page as we really made them for in-
    house applications.

    The stuff is out there, but since it is so simple to make your own,
    it most of us who make this stuff don't advertise.

    Dave

    I got into Stamps because I finally found a solution to
    this problem.

    See www.basicmicro.com. Look under Atom, Prototype boards.
    They now have a package with a board and an enclosure,
    finished product 1.5" thick by 2.6" wide by 4.5" long.
    (not including connectors).

    They have two boards, one for a 9-volt battery (batt door
    in enclosure, short board) and one without 9-volt
    (enclosure has no battery door, board has larger
    prototype area.) Both boards fit in both enclosures.
    Kit is around $30.00, plus $10.00 for a kit of parts.

    The Basic Atom is pin compatible with the Stamp, so their
    board is too. The kit of parts includes a regulator,
    socket, power connector, DB9, a few capacitors, etc.
    It can be soldered together in a few minutes.

    Check it out, I highly recommend it!

    Could you do this with a PLC?

    www.automationdirect.com has some relatively cheap PLC's with 2 serial
    ports. I would check out the new DL06 series (<$200+software) as I don't

    think the DL05 series can receive RS232 data -- only transmit.

    I wasn't thinking about salvaging a case from a dead product -- I was
    thinking about scavenging a working new product like a sprinkler
    controller unit. By replacing the controller chip with one I can re-
    program, I get the complete housing and complete circuit board, all
    the packaging new and neat and commercially done.

    It reminds me of the paradox of buying empty glass jars, cans or
    bottles. I can look in a chemistry catalog to get empty jars. But I
    can get the same jars for less if I just go to the supermarket for
    and buy the jars with product in them.

    Another story was the guy who opened up dot-matrix printers,
    disassembled the microcontroller inside, and reprogrammed it. He
    added a modem so that someone could turn on the printer and it would
    call a phone number, download some text and print it out as a
    report. 1980s.

    But it's just too much a luck factor to find a complete piece of
    equipment that has what I want in it -- the right peripherals,
    including clock generation capability, with a controller that I can
    replace. Unless I knew of such a unit, AND knew where to buy the
    development tools, I could not consider it.

    BasicAtom looks very interesting.

    The housing is strange. They don't cut out for the DB-9 connector,
    you have to cut it out yourself.

    The combination is strange -- they only offer the housing with a bare
    board, how a i supposed to populate it? They should offer the
    housing as an accessory, and/or in a Complete kit.

    They have hardware PWM, even one that free-runs! Great thought, but
    they can only count to 16K, so the lowest frequency is 20MHz/16383 =
    1.221KHz. My app needs clock 20Hz to 200Hz max.

    The PLCs there are tempting. I should have considered that a
    packaged microcontroller is often called a PLC.

    It would take a lot of searching to find a PLC that matches my
    application.

    The DL05 series can only transmit, i think i confirmed that.
    The DL06 series is more advanced, they can receive -OR- send, but not
    both in the same program!!, if you can believe what I think I read.

    There's a bit of a hill to climb with standard PLCs anyway. The PWM
    output is probably easier to control than in various Stamps or
    microcontrollers, but it could be very difficult to code for a serial
    dialog, using Ladder Logic. (Some PLCs might allow BASIC or other
    sequential language.)

    I thought that was strange, that they would
    offer such a perfect box, and then not
    provide a cut-out panel for it.

    http://www.basicmicro.com/Products.aspx?CategoryID=11
    has a $10.00 kit of parts for the "LCD Enclosure"
    which populates it.

    You wind up with a 24-pin socket which will take
    the Stamp2, BasicAtom, or BasicX-24.
    I've tried all three with no problems.

    It has a 2-1/2 x 2 inch prototyping area on-card,
    fully tinned. I like the "LCD Enclosure" kit because
    it has a larger prototyping area. Note I have
    never actually used one for an LCD.

    The Atom provides a Basic Interrupt to three
    hardware timers, this should be perfect for your application.

    And yes, they sell Box only, Board only, Parts
    only, or Board With Box. You just have to browse
    the page above to find the combination you want.

    BTW, the box is the PacTec HML-ET ($5.00 from PacTec).
    The 9-volt box is the PacTec HML-9VB-ET.
