Here is the streamer that I have just made. Is just a first prototype to check if all fits fine. I just wanted a device that allow me to stream music from Tidal or online radio from my desk to my music system at the other side of the room (About 7 meters). I’m using a Senheiser USB Bluetooth adapter that allow Aptx HD.
A new 3D printed body will come with a better and nicer material. Also with a couple of improvements, like an start monetary switch like in the next render, and provably a power management board to simplify all the internal cable management.
Is a 7 inch Luckfox touchscreen. I have to say that this company have a great customer service. When I asked for some dimensions of the screen, they sent me the full CAD of it. And they also made the config.txt and user config.txt files when I had problems to get Image from the RPI. By the way, is a RPI 4 with 2 GB of RAM.
Hi,
that looks great. My prototype is still mounted on a piece of an old shelf. Do you have the 3d print files published somewhere (thingiserve for example)? I would also like to use this case for my installation.
Beste Grüße

noch nicht. Not jet. As I say, I´m going to make a second case with a couple of improvements. For example the screen frame in the CAD was fine, but the printed part in PLA was a little bit small in X, and I had to sand it a bit to fit the screen. But once is done, I will share the files and a bill of materials needed for the assembly.
I´m still working in the modifications in the case before asking my friend to print me the part. I want to include a Micro SD card extension cable. Now the SD card reader of the Pi is not accessible, and the PI should be disassembled to operate it. I didn´t touch it since I build the prototype, but I think is good “nice to have”. It means that I will have to make the rear of the case about 20mm longer (Or include a M.2 SSD board and let the case like it is now).
But the main change in my concept is removing the Bluetooth of the equation. I bought a second Raspberry Pi 4 2Gb to use it as slave unit next to my DAC. With an Argon One V2 case.
I hope to have the slave unit in working in a couple of weeks. Now come the most complicate part of the project for me, the scrips for the Argon One fan and on of button.
Sorry for so long time since my last update. Not many free time for hobbys. Here are some pictures of the second case prototype I get a couple of weeks ago. Is made in PLA+CF, lava gray color. Looks good, but I liked more the first black one. I’m making some renders with the case printed in aluminion color. With this material, the screen frame don’t fit perfectly, so I will have to sand it a bit or get a second one printed a little bit larger. Depending of each material, the contraction is going to be diffferent.
The rear of the case is 15mm longer, in order to get place for a card reader extender. Now is possible to remove the SD card trough one slot bellow the Pi. I didn’t coment it before, but next to the Pi, there is place to install a Hifiberry DAC (Or similar adapting the holes possition).
About the switch. To simplify all the internal wiring, now I’m powering the Pi from the screen (I’m using a 5V 5A power supply). So now I’m using the 2 5V pins of the PI’s GPIO and the groung next to them. The one just in front of the GPIO 3. The plan is to use the GPIO 3 to turn on/off the PI, so can I use any other ground pin with it? Witch PINs are recomended to power the LED?
About publishing the STL files. I will probably do it when I have the final design. In the first prototype the screws have been threadted directly into the plastic. In the second one, it has threaded inserts.
And is not bad to add a please after the request.
