Quasar ARM help

Hi

Can i use mcp604 as mcp6022 in this pcb?

Thanks

[GSL]

It's possible, but not recommended. Some people have tried to use, but the result is not satisfactory

Thanks. I put mcp602 on pcb. now i dont have any action in balance

90
0mv

What is the problem?
please help

[saber]

No action In balance:
99
0ma

[GSL]

No action In balance:
99
0ma

0 mA means there is no resonance of coil TX, or coil is not connected.

With other chip adjusts the balance was OK?

Thank man

I'll rebuild the pcb and made a dip ver of it. Its work good

I have 28cm tgsl dd coil. What is good "mv" in coil balance option?

Please help me for make 40cm dd coil for it

Thanks

Use these data coil :
Tx = 40 w , d = 0,4 mm , C = 330H
Rx = 200 w, d = 0,2 mm , C = 33H

Hi,
I'm making my own SMD version. Could someone confirm the C7 value of the RC filter before the ADC ? 2200 ?
Having a look on the Russian Tiny version, the capacitor seems very small on the PCB, i would say 2200pF = 2.2nF but i'm not sure.
I also have a question about Tx and RX, some caps are placed next to the TX and RX pins (C1 and C6) but you need to put a 300nF on TX (serial) and 33nF on RX (//). It's a bit puzzled for me.
Thanks and i'll share my file when it'll be done.

Hello,
In the Autors Schematic C7 is market as 22 this means 22pF (it is not an ADC it is an OP amp). Iam not sure, witch version of the Schematic you mean, I take a look at this from the outors Site. There are two Cs, C1 100nF in Line with the Rx Coil and C35 330nF in line with the Tx Coil. The C1 Capacitor is on the Board, parallel to the Rx Coil is a Capacitor with 22…33nF witch is not in the Schematic because it is in the Sensor housing. The Capacitor C35 is in the Schematic but not printet at the board, it is in the Sensor housing to.

Hi,
I'm talking about the shematic on this site :
http://www.radio-magic.ru/images/articles/md/qasar.png
The MCP3201 is 12 BITS ADC which use SPI for data connexion with the MCU. The MCP633 is an OPAMP. Maybe we don't talk about the same shematic.
Can you confirm that ?

Ahh,
there is the different point, you are building the Quasar AVR, the other one is the Quasar ARM. http://fandy.ucoz.org/publ/metallois...m_quot/2-1-0-5 this is the Site of the ARM and AVR Version.

Ah, sorry, i forgot to tell about this.
So, what about my 2200 cap, they mean 2200pf?
Thanks
