[Moved] Need help with panel meter - Employment/Project

[SSShocked]

i need help for my power supply panel meter
i need a meter that shows me:
out and drain current,power and volts
load resistance,capacitance and inductance

please help me

the max.power is 1200w(must measure up to 300v 50a)

please help me
i am ready to pay

my problem is that the atmega32 won't have enough memory

Re: need help with panel meter

Are you talking about ordinary analog meters? No doubt you'll need more than one.

Say you have a raw galvanometer with a 1mA scale. Resistance might be 100 ohms.

To read up to 300V you'll install a 300K resistor inline.

To read up to 50A, you might install a few inches of, say 6 gauge wire as a shunt. However this gets unwieldy. It can endanger the meter if connections get loose. So instead maybe you'll go with a method involving amplification of a hall-effect sensor.

Re: need help with panel meter

i want big 240x320 display

Re: need help with panel meter



or 20x4 or 40x4
or something
i will freak out of happines i i realize this display

Re: need help with panel meter



or this

can be 20x2 or 40x2

I have no experience as to a pic or microcontroller.

If you're running out of memory then you might gain some back if you...

Use lower screen resolution.

Use fewer digits of accuracy.

Do you use base 2 logarithms to do floating point multiplication and division? Would it consume less memory if you were to use repeated addition and subtraction...
to calculate power (watts, V x A),
and load resistance (V/A)?

Re: need help with panel meter

dude
i don't know how to program these IC's!
i dont have a programmer too

also i want to make this meter
i dont have it
it just flashed in my mind

Re: need help with panel meter

There are several Serial GLCDs available with built-in routines which takes most of the complex coding out of managing a GLCD.

Example:

Serial Graphic LCD 160x128

Such devices simplify the implementation of complex graphical meters and readouts.

Many use a standard UART to communicate with the host MCU.

Example:

Graphic LCD VU Meters

Re: need help with panel meter

funnnnn

but still i need somebody to help me
i will pay if it needs
tell me if you can do something

---------- Post added at 18:38 ---------- Previous post was at 18:28 ----------

nice
but still i need this display
do you know somebody that can make me the schematics and the code
or at least the code
SOS
HELP!
HELP!
HEEEELP
ANYBODY HEAR ME
HEEEEEEELP
SAVE MEEEEEEE...

am goin krazzzy

You'll probably receive several inquiries to your job/project offer.

I suggest you write up a detailed proposal as to your requirements for the panel meter.

look at he two photos at posts #4 and #5
it MUST measure
500v max with very high accuracy (0.01v if possibe)
50a max with very high accuracy (0.001a if possibe)
2000w max with very high accuracy (0.1w if possibe)
125 deg.C max if possible with accuracy 0.5 deg.C
i will be happy if it shows me the temp. in Celsius and Farenheit
you calc. the resistance

I WON'T PUBLISH AND SELL YOUR SCHEMATICS/CODE
IF I WANT TO DO SO I WILL ASK YOU AND PUBLISH OR SELL THEM WITH YOUR PERMISSION
YOU SAY WHAT I DO WITH THEM
ALSO I LIVE IN BULGARIA SO I WILL PAY WITH PAYPAL
I DONT SCREAM I JUST WANT YO TO GIVE SPECIAL CARE TO THIS

i know this is a site for discussing problems,etc.
but i really need help

---------- Post added at 19:15 ---------- Previous post was at 19:10 ----------

this is my electronics dream
also i will share my awesome schematics
of the PSU if somebody helps me

 

[SSShocked]

if somebody can do this i will be verry happy

 

[Zerox100]

I Can do that with AVR Micro.

You should concentrate on ADC sampling, I sugest of using CT, but your needs for high accuracy level may be discutable. Consider usage of 18bit or 24bit ADC.

Second part of your needs is for LCD, for that look MikroElektronika tool Visual GLCD & Visual TFT. Link http://www.visualglcd.com/
