I suggest that you post photos as well as a small description of your completed projects here.
Given the many possibilities that we can achieve, it is very interesting to share our creations!

Here is one of my squeeze ESP32s which is an addon to my living room amplifier.

• Made in a black anodized aluminum case.
• Driven by an ESP32-WROVER-B on a homemade PCB.
• The front panel in blue plexiglass hides an IPS ST7735 160x80px screen, an IR receiver TSOP4838 and a touch switch TTP223 (Power)
• The output is analog (DAC: PCM5102), it is not amplified.
• For power, it is a USB cable
• The remote control is from an old Philips TV (Combi TV/VCR) which fits perfectly (Code RC5)
• It has an external Wifi/BT antenna

As far as I remember the "xbox one media remote" should also work, and you can easily get cheap alternatives at ebay.

Using the Louder ESP Board bought on Tindie for few bucks has a TAS5805M Amplifier that does 2x23W.
Enough for most small satellite Speakers or 4" bookshelf speakers.

As long as it's anything decent and not such crappy things as those Cambridge Audio Mini Minx 20 it sounds quite decent.

Getting a few more board and other speakers I'm one step closer to the dream of a Multi room Audio Setup.

The next thing would be a Willow Setup. (And microphones on all those Speakers) for Voice control.

Edit:
Also got some decent Speakers.

Just had to cover all the LEDs because it's a 24/7 device in my bedroom.

I have a ESP32-A1S, and I found a $3 box in Dollarama. It would be enough to hold all the components.

• ESP32-A1S
• Rotary Encoder
• IR Receiver
• ST7789 TFT Display

Hello dear holefrog !
Thank you very much for your answer and for the NVS parameters (almost completely the same)!
I also tried many GPIOs, but with no result.
I am attaching a screenshot of the UART output and the configuration/boot log. Would it be difficult for you to take a look? When I press any button on the remote control, error messages are visible in the UART output window. I don't understand why I'm getting these errors?

Surprisingly, today, after several reboots, the reaction to pressing the remote control buttons in the terminal has changed!
Unfortunately, I don’t have any of the ones suggested in the thread about IR control. Now the question is: how can I get another of the remote controls I have to work? Do I need to somehow additionally convert the button codes so that the LMS begins to recognize them?

[philippe44]

LMS can have custom codes for IR, it's one of the config files. I don't remember which one exactly but even ChatGPT might be able to answer

[holefrog]

Hi, Androssboy

I can understand your current feelings, just like mine several months ago. It looks like exactly the problem I had before. My problem was:

I (38848) IR: can't decode IR signal of len 18 
I (38848) IR: 10 26 cd 8e 08 29 ef 83 f4 04 c6 83 02 05 b8 83  
I (38848) IR: 14 05 a5 83 ef 04 cb 83 04 05 b6 83 e7 04 ba 83 
 I (38868) IR: f6 04 c4 83 20 0e bb 83 90 12 a2 83 91 09 c5 83  
I (38868) IR: 0c 05 98 83 a9 09 ab 83 e7 04 d2 83 1e 05 85 83  
I (38878) IR: 8e 09 c8 83 08 05 00 80 

I am new to LMS and SqueezeLite too. Renber78 helped me a lot at IR. You can find it in the topic [https://github.com//discussions/330]. The cause of the wrong decoding is the GPIOs of IR. I moved my previous GPIO of IR to my current set and fixed the decoding problem. Just try to use my current setting for IR and test again. To isolate the cause, you may disconnect all other peripherals.

[philippe44]

What gpio do you use?

[alidaf]

I've just finished a new 3D printed SqueezeAMP case to complement my other designs. I designed the speakers, which are also 3D printed. The small ones were using some old drivers I found with no information on them but the Hecate 1s use some decent Mark Audio CHN-50 drivers. The new SqueezeAMP case is middle top in the first photo, middle in the second, and on it's own in the last few. The others are various early versions of basic WROVER dev boards with third party DACs or SPDIF boards, a couple of MAX9744 amplifiers with volume display and IR, a TPA3250 power amp and VU meters. My very first design was for PiCorePlayer in the second photo (with the full colour display). I'm also currently working on a dual led matrix spectrum analyser and a valve pre-amp.

The dial on the SqueezeAMP is actually a rotary encoder with 5 buttons built-in so there are a lot of configuration options for UI navigation.

I'll be posting the step files for the SqueezeAMP case on Printables once I've taken stock of the extra components needed. @philippe44 has also asked for a Li-ion battery option so I will be doing some further space optimisation to try and accommodate that request, which I may complete also before posting the files.

[sle118]

Very nice. Could you also post a close up of the rotary with integrated buttons? I'm intrigued.

[alidaf]

Here's the product link - I think it'll be better and more explanatory than my photography! The breakout is sold separately but they still remain reasonably cheap.
I've made it slightly recessed without affecting the performance. There is an inner ring that spins and the directional buttons are behind the outer ring, plus the usual rotary centre clicker. I came across it by chance after already ordering a load of buttons, which is typically ironic.

[bungh0l10]

Wow this is awesome! @alidaf are you accepting orders for those cases by any chance ? ^^

[alidaf]

If you mean the SqueezeAmp case, then I'm just trying to source another cable for the connector for a SqueezeAMP board to build another but produce step by step photos and then post the build process on Printables like my previous efforts here, at which point the whole thing will be open-sourced and then possible for anyone to print. I tend to build 2 of every project I make. The first is the prototype and the second is the more deliberate, methodical documentation. I've been trying to source a second cable for months but the postage is ridiculous unless I spend orders of magnitude more on other products that I don't need so the process has effectively stalled.

The main concern I have for selling a case would be tolerances with the displays (they are very variable) and you being able to source the same components yourself, but it is a possibility. I can supply Everything except the SqueezeAmp board and cables/wires, all fitted if needed but I wouldn't be keen on doing all the soldering and crimping again. Also, be aware that I had to remove the IR from the squeezeamp board and solder a new header in it's place. The display and sockets are from AliExpress, so easily sourced. The rotary dial can be bought from Mouser or Digikey but the optical pass-through was from a UK supplier so could be an issue if you are outside the UK. Adapting the design to an alternative wouldn't be a problem but getting hold of one myself could be, and that's the trap I fell into with the SqueezeAmp cable.

There are some other options at the link given earlier too. I'm about to add an optical output to the PCM5102 and ES9018 cases, at which point my SqueezeAmp case will become redundant and I could sell that (minus the SqueezeAmp board), since I only use the optical out on it. Once the second is built I'll probably sell that minus the board as well but the colour scheme is different (grey and blue).

I don't think it's possible to PM me here but can through Printables.

[zarss]

Not as neat as yours, but exactly what I was after. One is set as left, another as right channels.

[alidaf]

Nice hacks. I'm always impressed with repurposing things like this. I'd like to do some real classic stuff - it's just finding the right skip before the vultures get there first.

[rjgrandy]

I gutted an echo 4th gen and replaced with: ESP32, PCM5102, Parts Express 320-608 small 2.1 Amplifier Board, and a buck converter.

It works okay. The 2.1 board needs >7V to function properly, and can go up to 18V. So I fed 18V to the amp and the buck which cuts it to 5V to supply the rest. I'm not sure this is a good method to do this, I think I introduce lot of noise, also my circuit is not built super tight.

I was really happy with my 3D printed circuit board frame, and my 3D printed button board replacement..

Not sure if there is a better 2.1 board I can get for this but, this was the only cheap/small enough option to fit in the case.

All that said it looks nice, is 2.1 audio, reuses the same buttons and sounds decent.
