LCD Voltage Meter Module Source

[D from BC]

Where's a nice source of LCD panel mount voltage meter modules these
days.?
With backlight would be nice..

Be nice if it's a <$10.00 item.

I'm thinking of putting some V and I displays on my variable power
supply.
+ my temperature sensor could use a display..
+ my test load could use a display.

Lascar Electronics has a good range. Not < $10.00 though.

I like the Lascar one hole mounting thingummies

Not < $10.00 though.

www.allelectronics.com - but then you have to get them into Canada
without adding an arm and a leg to the price.

14.49 Euro, say 21 $
has backlight, adjustable decimal point, 9-12V supply, about 1mA current.
Next time you are in Europe perhaps

E*ay! (from China of course) . Search on "LCD panel meter". There's about 82
hovering on the $10 mark. (The Blue ones look really good on a panel).

Huhhh.. E*bay again....
Well...I guess I don't have to think about winning the bid or getting
sniped on this stuff.
I suspect the seller has mountain loads of these modules..

Cool
Blue LED voltage modules too

China it is....What a price??

I hope I don't get a note in the package that says
"Help me..Me 10 yer old. I trapped in bottom of Fang Gu elecktroniks
company. I get beated if I do not assemble..please help"

Had a similar natural hesitation/reticence a couple of years ago. So had a
trial buy of a TV card for the PC. Price was so cheap I ended up thinking
"to hell with it" and risked the few dollars it cost. Turned up 7 days later
and I've been buying from over there ever since. I've spent many thousands
of dollars with absolutely no problems.
Just bought a load of stuff. One item was ...

2000 SM capacitors in that nice case. What a price!.

I go out of my way not to buy stuff from China. It isn't easy
nowadays.

Let's see. Tariff for a Chinese car entering the US.: 2%. Tariff for a
US car entering China: 20%

More evidence of the incompetence of the Bushies, as if you needed any
more.

Just beware that almost all the "budget" types cannot operate properly with a
supply rail common to the measured circuit. That leaves you needing to provide
1mA or so from "somewhere" - a battery, extra transformer winding, ...

Yes that is so.
My own soultion to these things is a bit different:
Use for example *one* 2 line ASCII LCD with backlight, and a 2$ PIC:

In one corner... weighing in at $4 + $10.00 shipping
is the Asian voltage module.

In the other corner...weighting in at ?? display cost and $2.00 for a
PIC + shipping is the DIY PIC voltage module.

Round 1

PIC throws the first punch... Pow!
Few code changes are required as Microchip has public examples for
display and acquisition..

Asian module fights back with "Ready to use" punch ..Pow!

PIC module staggers a bit.., dances around..2 punches Pow! Pow!
The PIC can get the job of doing any other logic needed.

....and so on and so on...

you've missed the point entirely. If you plan on using one of these
(milli-)volt DPM's on your bench power supply, you need to fart around
generating an isolated power source for it. That is both time and money.

Game over.

Well, depends, one pot core, 1 transistor, 3 caps, 1 resistor, some turns,
and 12 turns + 1 diode + 1 elco for each meter.
But if you wanted 'backlight' then also you likely want 'V' (volt),
or mV, or 'A'(ampere), or mA displayed with light.
This is one more reason I use the 2 line ASCII displays, it shows the units.
Else you need to make a frontpanel with floodlight....?
Not to mention other messages, like 'in current limit', etc.
A human oriented user interface is a big seller.

Back to the match

However, as someone pointed out, how are you going to power them?

I'd probably use a $1.00 linear supply (wallwart) from the local
thrift(junk) store.
