Thank you!

Thanks ryanj, my pleasure! This community brought me more than what I did. I shall say thank you to you all .

Just wish your are the diyAudio moderator, they even don't accept my article about FIFO for no reason . My friend George and me spent a lot of time on it .

Regards,

Ian

did they say they didnt accept it, or just not reply? how about you send it to Jan Didden, who is responsible for Linear Audio which has been going from strength to strength, the latest edition is packed with excellent articles from people like Walt Jung, Scott Wurcer etc. still hasnt got a PDF version, but distribution is getting wider and wider. perhaps then DIYA will accept your article =P. I'm on speaking terms with a few of the Mods, want me to see if I can get it noticed? they are all pretty busy and simply may not have had the time.

Salas might be a good person to contact about it actually

I will speak with Mark - Variac at Burning Amp which is next week. Jan will be there as well.

Perfect! certainly a level of contact/influence I cant emulate; lucky you man, wish I could be there....

do you have a novelty food-stuff preparation implement you bring with you also?

Ian,

Got the isolater board thank you. Looks great - even the board is cut where the isolation occours

I will place the component order for this and the battery management board these days and I also think it is time for me to invest in a dedicated smd rework station (OT: any <200$ suggestions would be welcome by PM)

Cheers,

Nic

Received the isolator board yesterday and soldered all the components today. Connected it to FIFO and clock board, use separate batteries (2xLiFe=6.6V) for clock and FIFO. All LEDs "on" but the SPDIF input card not function. Remove the isolator board, everything fine. Voltage to the ICs on the isolator board are 3.2XXV. While still finding the fault, smoke came out from the clock board, a component next to the FIFO letters on fire!!!Looks like a capacitor.

What shall I do?

[qusp]

did you make the necessary adjustments to the clock board to use an independent supply?

that actually looks like an inductor, but I dont have the board with me at te moment

yeah lifepo4 batteries dont exactly have a current limit.... myself i'll be testing with inline fuses unconnected to the fifo board first. i'll have a think and look over the isolator board BOM/schematic, but in the meantime can you explain how exactly you supplied power?

[qusp]

yep, you didnt prepare the clock board

it is indeed an inductor, its L11,..the one you are supposed to remove before applying independent power....

whoops

from the clock board manual

- J5, Optional DC input, (do not use if interface with FIFO board normally)
Optional independent DC power supply input for Dual XO Clock Board. FB L11 has to be removed before use this DC

This is why I don't sign up for test boards. I wouldn't get past first base.
