so, 😉
essabre-90xx-rpi.sfb2 has finally moved..was a bit more work then expected, right now i´m not 100% satisfied with the result->had btw. to change the symlinks-structure in wordpress, so some pics/categories will have another url + the “direct”-forum-link (at the top) has changed to a “2-click-experience” 😉 + some minor changes, but overall i think its now a little bit faster + on a newer OS + a newer php-version..

second i´ve ordered some SSD1306 mini-tft-display test-wise some months ago, set it up on the third !! Arduino Uno finally (i´ve ordered 2 other Unos “in-a-row” and they were both damaged) and got the following result (for u to see it in real life, to maybe get some ideas for your DIY-DAC)..

absolutely easy wiring + sketch;.ino is here->Link

third got by chance some really simple ESP32 Bluetooth-serial tutorial on “Random-Nerds“; ( 😉 ) maybe interesting for you->https://randomnerdtutorials.com/esp32-bluetooth-classic-arduino-ide/
fourth no new Volumio-version is out and a new drop is the SMSL-SU 8 Version 2 with two (dual) ES9038Q2M for 200$ instead of 250$->Link

 

fifth, no other news concerning the ES9038Q2M, nothing spectacular in the diyaudio.com-forum about it->https://www.diyaudio.com/forums/digital-line-level/314935-es9038q2m-board-446.html
sixth i´m still planning to buy some 15V-0V-15V toroidal transformer and for the case i was looking for some “3D-printer”-layouts/submittals; had found a site (don´t know the url right now) and maybe we could make a new “thread” here or at the forum, for some “3D-printer”-submittals for the case !!

more to come + greets for now !!

essabre-90xx-rpi.sfb2.com will move (to a new server) + Nuforce Udac5 + SMSL SMSL X-USB II

unfortunately nothing new here in “modding” the ES9038Q2M; still on the search for the right transformer->there are some on Ebay+Aliexpress+Audiophonics but didnt make a choice till now:(15V-0V-15V)

Moode is now at V5.0-> (http://moodeaudio.org/)

and as also said in their description->
“Most USB audio devices work with moOde via the Linux kernel USB audio driver but some devices with high speed UAC2 chipsets may require the USB (UAC2) work around in System Config”
“the way-to-go” (and to get “real” DoP/DSD) is nowadays (IMO) via some XMOS-USB-device->I2S->ES90XX..
we had it here in discussion, and with the new USB2.0(3.0) linux-kernel-driver u can achieve real DoP/DSD with the ES9038Q2M; and only then..
by that, as also said, with USB3.0, + a wonderful xmos-bridge (see some posts before) + ES9038Q2M u already have a superb “tune”, really near to the “unbeaten” raspberry pi-I2S-ES9038Q2M-connection..(and its absolutely more comfortable)..
by that in speaking of a wonderful XMOS-usb-bridge we have now here a “SMSL X-USB II Digital Interface USB XMOS U208 to I2S LVDS HDMI ” (70€) with I2S->over HDMI which also said in some posts before, is the most “handiest “-possibilty to connect to an ES9038Q2M (with some I2S->LVDS converter directly connected to the dac-board)->

by that “essabre-90xx-rpi.sfb2.com” will move next month or so to a new server due to cost/performance reasons; i hope i can move this site/blog/forum without great problems to the new location; excuse me then for any conveniance->a mirror (from this site) is just set-up at -> http://essabre.ddnss.org <- is just right now only for testing; the main url (essabre-90xx-rpi.sfb2.com will (hopefully, 99%) remain); u can test the above-url performance-wise.. (more > Nuforce Udac5 in Part 2)..
greets for now !!
