as i´ve got today an old Philips BDP9500 (couldn´t read any discs (“no disc”) anymore, cheap, Ebay, 18€ !! (incl.shipping)) + also this Dual AC to DC rectifier->http://essabre-90xx-rpi.sfb2.com/?p=2708 i can finally start/begin with some “example”-tutorial how to build your own DIY-DAC !! (main “goal” on this essabre-site 😉 )
it´s only an example/showcase how to eventually do it..(a little story to begin with now):
okay, as this BDP9500 is trés chic 😉 (a really nice “blue”-light at the bottom) + massive, brushed, aluminium case and has this separated, dual power supply (one via some toroidal with 18V1 + 18V2 for audio) and one “power-line” with +12V-0–12V for the video section (+ also with some +5V/GND-lines)(i knew this “hifi-high-end-build-up” from the BDP9700 “Fidelio”(599€)->http://essabre-90xx-rpi.sfb2.com/?p=2576 and thats why i bought this BDP9500), we have now to find a way how to fit the other parts in it (the ES9028/38Q2M-board, the ESP32, AK4113,LCD1602 + oled-display (maybe a Pi 4), usb-bridge etc..)
it is really a long story/tutorial (cause i wanted to post the circuit diagramms from the Parts of the BDP9500 too etc..), a lot to do, and so i will post also a lot of steps (parts(ideas) “in between”)..
Part 1 (today):
as i´m relatively “unsure” if this +12V-0–12V works (from the second power-supply), i will use an old ES9028Q2M (want not to “destroy” some new ES9038Q2M) ->…
more to come …!! 😉
