Just a few days ago the PCBs for VAmeter v3 came in.
VAmeter is a simple board that connects to your existing power supply and shows the volatge, current, etc.
Upon building, the major fault was discovered. There was no connection to the input voltage so the unit is unable to measure the input voltage. It is only able to measure the current.
However, This can be fixed by adding two more flying resistors to the board, but that makes the PCB design a failure.
Hi, Arup - I tried by only running refreagrator alon and take five observation of electric meter reading. It seen the saving about 5% . If we connect just after output of electric meter wire, is it will work for whole house. If as per load it required more than one capacitor. how they should connect?
I bring one capacitor with following specification. PL. tell By calulaton how many tubes of 40W will covered by this single one. If its need to connect more than one, PL. provide circuit.
Specificatons - 6.0 Hf 440 VAC, 50/60Hz.
Thanks

Arup,
Your board and the design are not failures.
You have found the problem on the board, you have have specified a correction, and you have specified the components needed to correct the situation. By doing that; you, your design, and your pcb board are successes.
Thanks for the nice words. I'll make it working soon....
Arup,
Can you please change the ISP connector to the Atmel standard. Its diagionally opposite as shown.
Thanks
Thanks Kevcav
I didn't know it was diagonally opposite. In the case just installing the ISP header at the bottom of the PCB will do the job.
Hi Arup, great job, but are you still working on "the correct" version of this AVmeter ? And...are you going to release the software (*.hex file) for this AVmeter ?
Thanks for your reply. Martin
We are waiting for fixed version 3 🙂 Would be great to get it soon 🙂
Hi my friend Arup.
Thanks from this SCH.
Please does the HEX file is same like from version V 2.0.?
On SCH, I do not see crystal?
How do I need to set up FUSE from burning ATMEGA8.?
Best Regards
No need to burn fuse. Factory default 1Mhz internal RC oscillator will work fine in this....
Thank my friend.
But, for this unit v3.0 is the hex file MAIN.HEX or it is different ?!
Best Regards and have a nice day!

Hello,
I have tried to make a breadboard of V2 but I only have an atmega328p chip. Is there anyway I can alter the code to use this chip?
I can program the atmega328p with AVRDUDE but there is nothing showing on the LCD.
Any suggestions would be appreciated.
