Success Cases

I think you can replace the spring in the buttons with one that is harder to press?

Unfortunately, I don’t know which keys to order. Do you know which ones would be adequate, harder?

Hi @sebastian,

I haven’t had any issues of sort so far, with the feedback accuracy of the keys, on my two keypad models (12 keys + 4 encoders and 15 keys + 3 encoders).

They click sound and reliably, with the appropriate degree of physical resistance. Sure, their aptic response is quite different from that of the excellent V5 rubber pad, especially with bold/long presses, but imho the two solutions simply represent distinct flavours of equally functional keyboard actions.

Best regards :slight_smile:

I’m sorry but i have very little exact knowledge and often find myself confused when scrolling through the endless possibilities an aliexpress. But i think you can try and msg the seller and ask? Or take apart one key cap and have look at the clicker underneath.

But also as Aethermind says; There are different flavours. But also habits plays a role. I’ve learned that quite as often i find tools or ideas difficult to internalize just because they are unfamiliar to me.

I can only comment on the two models I own, but, assuming that two samples of a given object are enough for a statistically consistent analysis (which obviously aren’t), the keys on my keypads feel exactly the same.

Regards

Just true :ok_hand:

Well, now it is time to present my visually pleasing (at least so I think) latest Zynthian contraption (I do not dare qualifying it with the blazoned title Success Case). It was essentially meant to recycle a spare Pi4, leftover from the V5 > V 5.1 update.

I ordered from AliExpress an apparently apt Unew 8” touch display with Raspi case. Long story short: the manifacturing of the innards, advertised as capable of holding safely and conveniently the computer board, was manifestly poor, with PSU and micro-HDMI adapters extremely prone to rupture. Moreover, the built-in active cooler was unbearably noisy. Thus, I ended up enclosing the Pi4 in a lovely machined grey aluminium KKSB case from Amazon.

The touchscreen was available from the factory only in a boring plain black ABS finish, which I unreservedly disliked straight away. After some deep research, I discovered that the English brand Army Painter provides an extensive palette of spray colours with embedded primer, for model-making and fantasy figurines in plastic, of which I rather predictably chose a beautiful Hydra Turquoise.

The audio compartment was implemented with a surprisingly well-sounding Sabrent USB-A micro interface (just mini-TRS stereo in and out, but enough for the purpose), and the Midi feed was done with a Y USB-C cable (data+power), through which my laptop recognised the Zynth as an available Midi out from Cubase, once I did the trick of sending MIDI data from a powered USB-C hub.

For the tactile interface, I got another model of the sturdy Romoral store keypads with potentiometers, from AliExpress: in this case a 15 keys + 3 pots variant. All the UX configuration was made through key-binding in webconf, and obviously I used on the UI one of my custom Zynthian colour profiles.

I cannot enjoy on this build the powerful and Pi-5 restricted DSP 56300 releases (which I adore, as many of you know), since at the core of this mini-system there is a Raspi4 with 8 GB and ordinary mSD storage.

Still, all in all it fares very well: the good, proven and time-honored Z plugins are there, it sounds clear and crisp despite the humble audio equipment, and the thermal dissipation through the full-metal enclosure is excellent.

It does look stunning Aethermind what you have built here, even if it “only” runs the rPI4 :slight_smile: Love the bluish colour of the casing which looks very nice. Also, i guess any heat-dissipation issues that you theoretically might have would be non-existent. The separate keypad is genious. In my mind, that is the ultimate controller. Great work :right_facing_fist:

OK! but……..:face_with_monocle: :face_with_monocle: :face_with_monocle: @wyleu docet….. :rofl:

Can’t a wyleu take a long relaxing bath without being disturbed. . . . ?
Those poor ghiasha’s have traveled a very long way . .

yep , definitely requires attention….

Agreed! :smile:

.. Does the backbone of a building rest? Then @wyleu can’t rest…:rofl:

That looks amazing.

Well i got the two Romoral keypads (link) - the ones with 12 keys and no BT or LED.
By removing som material from the base of the upper keypad and the rubber around the USB C plug i could fit them together like this:

Nect step: Route cavity for both keypads in a piece of plywood, outsource a “cable-spiral” and spiral the two cables inside. The longer must be dubled back a little inside the spiral so both USB A plugs are equidistant from the keypads. Off course i would maybe have preferred to do something like Toff’s done earlier in this thread, but i have plenty of USB ports i think.

Here is an article on Reddit
I’m buying brown switches here
I’ll let you know how it works when i get them!

I do not think Bluetooth keyboards are working with Zynthian? If they do i’d sure wish i had bought the BT Romoral keypads instead :slight_smile:

Hi, @core.east since I love drawing with Fusion 360 (I’m not an expert, but I’ll try), if you send me the exact measurements (But also the overall size in your case) or a link where I can see them, I could try to design a tray-like container to hold the two units together so that moving them doesn’t break the connector… if I can, I’ll post the print file here so anyone with a 3D printer can test it.

I don’t know if you can post any filetype in this discourse forum. You can certainly post a link to github or google drive or whatever vendor you like.

I have already uploaded .stl files of my Black Pearl case without any problems, also because they are only a few Kb.
