Success Cases

Nice case, love those knobs!

WOW @norbim ! This one is a beauty :heart_decoration:

Great build Norbin!! Love your cases.

Would love to hear your impression on how the Zynthian stacked up compared to the MB sampler? I was planning a MB sampler but changed my mind to the Z synth. Not that the MB is ‘bad’ but the Z seems more flexible.

I also have some of those LM2596 SMPS but was worried that the 2amp rating was too low. But if it will do the job, that sounds great.

Thanks Yogi,
comparing the MBSamplePlayer, this one is really flexible, especially if you want to play with different sample sets and synth technologies. The only drawback is that you have to wait for the OS and engine booting time when you switch it on.
The MBSP is only a “simple” sample player which plays simple wav files for every midi notes, the soundfont synthesis is a “bit” complicated method. I think the MBSP is a switch on and go solution, its perfect to inbuild to e.g. a mellotron or other “replica” instrument. For a long time I wanted to build a small Hammond emulator module, and I found Zynthian which has setBfree as a perfect solution. The other engines are really the bonuses for me.
Actually the LM2596 module is rated for 3 amps, but I think 2 amps would be also enough. I haven’t had any problem with it so far.

Great @norbim!! Really great build!! Congratulations!
I hope to hear some audio/video demo very soon!! :wink:

Best Regards!

…and finally… the “Success” post :slight_smile:

My first Zynthian is now fully assembled and tested (a good musician tested it, my “bang away” playing style is not a real test :wink: ) and ready to be given to the friend that asked me to build it.

It has been almost completely hand wired (but I’m used to hand wire prototypes well bigger than this… Zynthian worked the very first time I powered it)

I designed a 3D printable case for rPI3+PiTFT+HiFiBerry, STL files are on the github repository and on thingiverse. The case is made by many pieces, and each piece can be printed with the outer side on the printing bed, to have a nice and glossy surface. Parts fits on a quite small bed (18x16cm)

I’m thinking about making a thin (2D) printed decal to put on front panel, with key and control descriptions, like the offical one.

Here are some “work in progress” pictures.

My fantastic “spaghetti style” wiring :wink:

Almost done:

Everything in:

…and now? Already building my second one (for the musician that tested the first one and loved the idea of a “portable hammond”… probably I’ll build it directly inside one of his midi master keyboards :slight_smile:

And the third one will be for me, with AudioInjector board. It’ll be a good addition to synths that I can’t play :slight_smile:: the great Novation MiniNova, a Yamaha PSR3000, and the funny Pocket Operator PO-20 “Arcade”

Amazing @Axeman!

Congratulations for your great work!
It would be nice to have some video testing the case. The project really needs more video contents :wink:

Kind Regards!

I finally managed to get the screen mounted - after I destroyed the first attempt.
In case anybody needs a defect waveshare32 for “case studies” :slight_smile:

I chose the waveshare32, because it’s only about 20EUR.
The case was 6EUR and I should buy a new one now that I know, where all the holes should be.

Nice @mheidt! I love your box. And it seems quite small. Can you detail the dimensions? How did you make the holes? Did you use a “dremmel” or what?

Thanks!

Did i say 6€? 3…

I started with a Dremel but had to adjust with a file. It could be far cleaner.
My primary concern was the mounting of the screen. It has only screw holes in one corner. The knobs are holding it now :slight_smile:

Nice nanet! I just added a flag on Valencia :wink:
Only 2 quick questions:

  • You told me that the display is piTFT 2.8" capacitive, but there are 4 screen-holes in your case. Can you explain this? :wink:
  • What is the origin of your case?

Regards!

It could be the PiTFT “+” version, Both the capacitive and resistive versions have 4 holes.

@Axeman you’re right!

My display is a PiTFT 2.8 Plus with capacitive touch panel. Bought from Amazon:

The origin of the case? Simply a kind of electrical junction box I found at the electronics store.
(“RETEX” 101 series, model 33101004)

A bit of “decoration” using a dremel and a cutter, and Mr. Nanet enjoys his Zynthian! :joy:

Nice mounting, @beckdac! Congratulations!!

Is it working OK? What about the sound?
Probably you want to increase the font size in UI. You can do it from the webconf tool :wink:
