Yes the device must be powered for programming with or without volume board attached .

Do not forget to write fusebit : disable Jtag , Internal 8 MHz RC oscillator .
Fantastic! Thank you for the information.

I've costed the BoM up here in the UK through Farnell and RS is anyone's interested.

I'm in the process of moving house at the moment so the build is going to have to wait

Cheers

hii i m having some issue , i think i m wrong some where .. that is, that i m using pga2311 in the board and i connected the processor to it, and had forgoten to pull up the zce pin (1) and my chip had heated up bad ly, and now that i fixed it,
1) there is no control on volume it just comes at some high gain,
2) the display in between goes corrupt, it never happend when i was elektor issued articles program, using pga 2311 and pic18f452,

This cannot be because of zce pin.It must have another cause.
