Device needed for: Text Display + Wireless Communication + Remote control + Remote Power ?

Hello,

The following are the requirements for a piece or pieces of hardwa

A device which can stand on a table:

1. Dimensions: Approximately 20 centimeters width, 3 centimeters heigh, 2 or
3 centimeters thick.

2. The device should be capable of display text, about 20 to 30 characters.
(Probably led display)

3. The text should be remotely controlled by for example a PC.

4. The device should have a network chip.

5. The device should be uniquely identified because multiple of these
devices are necessary.

6. Each device should be remotedly controlled by the same PC and it should
be possible to send different text to each device.

7. The device should be able to work for at least 20 hours straight on for
example battery power or other form of mobile power storage/accu.

8. The battery/accu should be replaceable and possibly chargeable, should
charge rapidly within 4 hours.

9. Some kind of second device/pci express card (?) is needed for the PC,
perhaps wifi, blue tooth or something else to controll all of these table
devices, perhaps 20, perhaps 30, something like that.

10. The device should look good/polished... no loose wires, it should have a
nice black package around it or perhaps other color... something that looks
decent/finished.

Recommendations ?

Bye,
Skybuck.

Unfortunately all I have looked at won't do. Either not enough characters or
too big.

How about one of these beauties?

check

1. Dimensions: Approximately 20 centimeters width, 3 centimeters heigh,

The part that's not the full-stroke, keyboard is just a little bigger
than that.

2. The device should be capable of display text, about 20 to 30
characters. (Probably led display)

40 char x 8 line display

3. The text should be remotely controlled by for example a PC.

I think that could be accomplished.

4. The device should have a network chip.

RS-232c is probably being done off of a chip.

5. The device should be uniquely identified because multiple of these
devices are necessary.

check

6. Each device should be remotedly controlled by the same PC and it
should be possible to send different text to each device.

Given answer on #3, check

7. The device should be able to work for at least 20 hours straight on
for example battery power or other form of mobile power storage/accu.

check

8. The battery/accu should be replaceable and possibly chargeable,
should charge rapidly within 4 hours.

check, 4 x AA

9. Some kind of second device/pci express card (?) is needed for the PC,
perhaps wifi, blue tooth or something else to controll all of these
table devices, perhaps 20, perhaps 30, something like that.

your pc is your business in this recommendation

10. The device should look good/polished... no loose wires, it should

you saw the photo?

No won't do.

No keyboard, no multi line.

Just a simple device containing one line of text.

And it should probably be very bright, it will probably be used in a
somewhat darker place

So red leds or some kind of shiny display would be nice I think.

Bye,
Skybuck.

Ok, correction of dimensions:

The device has to be 10 centimeters by 2 centimeters and not thicker than
half a centimeter.

Please make new recommendations ?

Bye,
Skybuck

The rest stays the same:

Recommendations ?

Bye,
Skybuck.

In case this specific device/dimensions does not exist I am also open to
suggestion how to build this from parts.

So tiny led recommendations ?

Circuit boards perhaps ? Maybe wireless leds ?

Construction advices ? Hmm...

Computer/chips too hook up to it ?

Or if somebody can build it contact me via me e-mail address, skybuck 2000
at hotmail dot com.

Bye,
Skybuck.

The wireless requirement can probably be dropped if it's too much trouble.

However the device must be programmed to contain some text somehow... and it
should be easy and fast.

Perhaps via an usb plug or something else...

Bye,
Skybuck.

Hmm I have doubts about this... perhaps these devices would be stolen,
pretty quickly...

Idea might thave to go into the waste basket...

Not my idea anyway.

Bye,
Skybuck.

The theft part wouldn't be too hard to deal with. Use a protocol over
the wireless link that verifies the serial number without broadcasting
it. Then the displays can't be used by anyone else.

If you can't find something like this it would not be hard to build.
The only real issues I see are the battery life (just need a large
enough battery, but charge time might be an issue) and the number of
devices controlled from one interface. I think Bluetooth has a limit of
some 8 or so. However, since you don't need constant connections to the
slaves, but rather only when you wish to download text to them, I think
you can easily get around that limitation.

So figure out what size characters you want to use and pick an LED part
to suit. Virtually any MCU will do the job of interfacing to the
Bluetooth interface, the LEDs and managing the protocol. This should be
a fairly simple project. You can get the HC-05 Bluetooth module for $5
or less. I expect you can figure out how to charge an internal battery.
But then if you have to plug in the devices to charge, why not plug
them in to program as well? Oh yeah, you didn't say what range you
wanted on the wireless connection.
