Default 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.

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
have a nice black package around it or perhaps other color... something
that looks decent/finished.


you saw the photo?

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 ?

The rest stays the same:

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.

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

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...

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.

Skybuck.

https://learn.adafruit.com/32x16-32x...atrix/powering

"Power

Although LEDs are very efficient light sources, get enough of
them in one place and the current really adds up.

A single 32x16 or 32x32 RGB matrix, running full tilt (all
pixels set white), can require nearly 4 Amps of current! Double
that figure for a 64x32 matrix.

On average though, displaying typical graphics and animation,
these panels will use less. A 2A supply is usually sufficient
for a single 32x16 or 32x32 panel, or 4A for a 64x32 panel.
There’s no harm in using a larger power supply rated for more
Amps (e.g. a 10A supply), but never use one with a higher Voltage
(use 5V, period)!
"

So while having a battery powered LED display sounds nice, 20 hours
with a load like that is going to require car battery sized
supply sources.

Also, be careful of getting a display which is too bright. A
local business attempts to burn out your eyeballs, with their
LED sign. The result is, no human can actually face their sign
square, and people have to look away. As a result, nobody
can see the "sale" items, or nice pricing. The person
running the sign, is an idiot.

When a billboard sized LED sign was installed next to a local fire
station, the staff could no longer sleep, due to the gigantic
flashing LED light levels. For a period of time, a compromise
was reached, where the billboard was turned down, to "human"
light levels. Eventually, the billboard advertising company
removed the sign, realizing it was just a stupid idea. The old
mechanical rotating billboard signs, while crude, are a lot more
effective. Using an "eye-blaster" near a highway, isn't all that
clever. If you interfere with highway safety, run afoul of local
bylaws, you could be in for a lot of visits from inspectors.

*******

Another possibility would be OLEDs. I quick check on Chinese pricing,
shows about $200 a linear foot. Monochromatic. Yellow is a nice
color.

*******

A $2.00 piece of white card plus a black marker pen, is a
cheap alternative, has good contrast, and is just as effective.
