Absolutely simple Arduino IR-repeater for Hi-Fi Gear Cambridge Audio CA-540A or other..

so, 😉
after i´ve made some IR-Remote substitutions for my Cambridge Audio CA540 Azur Amp (see „Project-1“ and „Project-2“ and so on) here on the site with first Bluetooth and then Web-Control i´ve finally made it „over-simple“ 😉 and use an Arduino (2,50$) + some IR-receiver (VS1838B)(0,40$) + IR-Transmitter (0,40€) + some dupont-cable (also 0,50$ incl.shipping)->on aliexpress by example..->Link,Link,Link


the point was the right library for this and i used (many,many thx to „Eddy Yanto“ !!) the simple IR-repeater-library on github->https://github.com/eddyyanto/ir-repeater
point was that in description it says:“..This sketch receives the infrared signal on standard pin number 3, decodes and dump the infrared information on Serial and forward the raw infrared signal to pin number 4.“; but that works not !!
in the .ino on the other hand it says:“..int RECV_PIN = 4;
IRrecv irrecv(RECV_PIN);
IRsend irsend; // Defaults to pin 3“ and thats the opposite !! (works with the .ino-settings now of course)..
tried to reach him via e-mail to correct the description->no success until now..
anyway, u can now use almost any (hi-fi)-remote; place the ir-receiver at some point near u (and to which your remote can point/send to of course), make a dupont-cable-connection to your arduino in any length u wish and from there also in any length to the ir-transmitter !!
(the sketch only receives + transmit->no more other modifications to do in the sketch !! (noob-friendly 😉 )
easy as this and thats it ! 😉 (Total costs: 4$)
(working sketch is here btw.->Link) and on Github of course, again->https://github.com/eddyyanto/ir-repeater
by that i´ve bought some Burson V5i as D (Dual) and will report then about it !!

greets for now 😉

New XMOS-USB-Driver (Skysong/Singxer) -> v4.59.0_2019-02-13 + Massdrop ES9038Pro

hi there, 😉
found by chance on then shenzhenaudio-website this new XMOS-USB-driver V4.59 (02/13/2019)..is originally for the Singxer SU1/SU6;
tested here with with the Skysong(Singxer)-XMOS-USB-device (XU208)(+ES9038Q2M) on Win10 -> works fine !!
Link Essabre-90xx-rpi.sfb2.com->http://essabre-90xx-rpi.sfb2.com/pics/Singxer_USBAudio_v4.59.0_2019-02-13.rar

by that there is some Dual !! ES9038PRO on Massdrop->

->Dynamic range: 131 dB
USB: PCM 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz

interesting is the separation from the device + power supply..
it is the same principle as maybe earlier with the Mission Cyrus Amps 1-3 with an extra PSX which cost the same !! (and i had luckily here) and which remind us on the great importance of a clean, strong power supply !!

Massdrop: Burson V5i ->Dual !! 24,99$ (Single matched pair +15$)

so folks 😉,
sorry that i had lately not the time (and fun) to write here any further posts (+ time is changing here so fast concerning Pi-audio-distros and so on etc.); also i have to buy here some things first to post here more about „modding“ the ES9038Q2Ms..
but i found here right now an interesting offer by „Massdrop„-> some

BURSON V5i as single or dual !! ( Dual!! 24,99$ (or Single matched pair +15$)

so great !! 😉


hopp,hopp and get some !!!  😉

only 4 Days left !! (Drop is till March 24. 2019)

essabre-90xx-rpi.sfb2.com / registering not possible at present..

so folks, 😉
sorry about it; but „registering“ is not possible at present; but u can still leave some comments via the comment-„button“..
by that i/we have a great „hack-attack“ and so i have to delete a really great amount of „false-user“; it could be possible that your account will be deleted too..
i inform u if registering is functional again..
by that, outgoing mail is also not possible at present (for password-resetting and so on)..i work on it, but it can last a little bit longer..
kindly excuse any inconvenience !!

greets for now !! 😉
