The V5.1 passive cooling works very well. Probably better than most active cooling solutions you could find. Think that placing a fan on top of a processor doesn’t really solve the problem when the assemble is inside a box. You need to move the heat outside the box, this is the key.
Regarding the V5.1, with a “normal” ambient temperature of about 20-25ºC it’s rare to see the temperature going over 50ºC. When pushing hard the zynthian, you could go until 55-60ºC, but this is not common and you have to push very hard to go over 60. I never get it to throttle, not even getting close, no matter how hard i pushed the zynthian.
For the V5, based in the RPi4, it’s almost the same with 5-10ºC less
Of course, the case, specially the bottom part, can get warm. You can feel it when touching it, but it never would harm your hands. It’s simply warm.
We have observed that improving air convection, specially in the bottom part, improves heat dissipation in the V5 and V5.1 and it keeps temperature still lower. This is specially important when working with high ambient temperatures.
For this finality (among others!) we have created 2 different mounts:
angle mount
vesa mount (still better!)
that, apart from improving the view angle or allowing fast and safe mounting in stands and other supports, also improve heat dissipation on the V5 and V5.1.
Anyway, as i’ve explained, this is rarely needed unless you work in the hell … and in this case you should consider using an external big fan!
Thanks for the details. Cooling by the outer shell is an ideal solution, of course!
My current solution (just posted some pictures and description) is neither fully closed nor really “open” to air flow, but I usually get temperatures between 63 and 66. I think that is OK even without a fan. When trying to overclock to the maximum during the hot summer days, the temperatures reached 70 to 75 - probably still usable, but I don’t think I really need that, so I went back to the standard clocking and the lower temperatures below 70.
We will open the sale of the “upgrade kit” very soon, that basically is composed of the Pi5 thermal block and 2 inexpensive cables. We would consider selling just the thermal block in the next batch.
Wifi is activated and i can see my wireless network from Admin/Network in zyn-ui.
Being able to set up wifi from web-ui is still very valuable for networks with very long and complex passwords stored in password managers.
Alternatively, how could/should zynthian wifi config be edited from ssh/web-ui terminal (e.g. raspi-config, wpa_supplicant.conf etc)?
I have just installed it on my Pi 4 with official Pi 7 inch touch screen using a freshly burned image onto a new 128GByte Lexar micro SD card . It was a beautiful, pain free experience. All I had to do was select the hifi berry DAC light setting for my pHat DAC. No ethernet cable was required. I found my WiFi and logged in on the touchscreen using the new WiFi feature. It sounds great!
Thank you very much to everyone involved.
No. It doesn’t apply. It should be removed from wiki.
For more complex network configs, i would recommend to use the fantastic “nmcli” command from the webconf’s terminal. You will find a lot of tutorials about nmcli and it’s not difficult to use.
Developing a full-featured network configuration GUI is not in our roadmap. We have other priorities. Zynthian is not a PC, but a synthesizer/groovebox. You can do basic network configuration from the UI, including introducing quite complex passwords with a bunch of rare characters, but not all.
Anyway, you have easy access to the terminal from the webconf and you can do EVERYTHING from there.
