Time to share my new “Zynthian V5touch” embedded into Novation X-Station 61. (Unfortunately, you can discover some ugly glitches at closer look - I am just terribly awkward at cutting and any handwork generally.)
The Pi5 is mounted in a former battery compartment at the bottom of the device, which I leave open to get at least some air for the passive coolers. The Pi5 is wrapped in the common passive cooling case like this one (but I bought it cheaper somewhere else) and an additional aluminium cooler is mounted at its top (that is the one you see at the picture) - everything mounted upside down, of course. The outer cooler aligns almost perfectly with the bottom of the device. At first, I tried to add a small fan inside to blow towards the cooler (see the four small holes behind the opening) and improve the air flow, but it seems unnecessary with the second layer of passive cooling (I prefer absolutely quiet solutions). The usual horizontal position of the device is far from optimal, of course - the low rubber feet give it a minimal distance from the shelf it’s usually standing on.
Eventually, I also embedded the Hifiberry (RCA connectors on the left). The X-Station can also be used as a soundcard, but I have had some strange issues using it with Zynthian, so that I rather use the Hifiberry for output.
The two flat USB cables connect (and power) the Waveshare QLED touchscreen and the X-Station. A full-fledged 5A power source is necessary to also power the X-Station.
