SNIFFER XR -7

[ivconic]

Neat work!

I think somebody already posted corrections for those mentioned intentional mistakes, somewhere on this forum...
But here they are again:

Main PCB
T4 & T5 (Collector & Emitter twisted by 180 degree)
R38 = 1 Ohm
R34 need to be optimized
Modul PCB
T3 (Collector & Emitter twisted by 180 degree)

These are only if you made your device by famous book DBP2010.
Except very neat handmade, i cant really spot any mistake on your photos...
I made one of DBP2010 and with corrected mistakes, it is working excellent..
Regards!

Thanks Ivconic,
Thanks for informations.

I was particulary wondering about the parts around the 556 circuit,top left corner.
Yes i made it by the book,but there are several versions of it,with error corrected.Except for T3 on module i think that i have to check.
Regards!,
Fred.

Hi Erol!
You should recheck schematic od DBP2010 again. It seems that XR6 and XR7 are exact the same PI design. Only "difference" seems to be in pcb'c. XR6 is splitted on 3 pcb's and XR7 has one large, main pcb and one smaller "piggy" pcb...Also possible that XR7 is improved with few minor mods or maybe not.
But i have strong hunch those are exact the same.
So you dont need another schematic...you can use DBP2010 schematic, posted here on this forum, last year....as i remeber.
Just use search..
Regards!
