This is not mine, but I ran across this the other day while browsing Printables.

Impressive. This guy managed to build almost full V5 without single PCB. All hand wired with help of few strip boards. The most impressive is soldering so many tiny wires for led buttons.

Wonderful! The only immediately obvious drawbacks: size and active cooling.

For anyone looking to go old school there is also a Zynthian V4 design:

I saw this about 2 weeks ago, impressive indeed. I thought this person was already in here and posted about it.
I’m planning a similar hand soldering on PCB like him. I was happy I came accross someone who succeeded, only difference is that I bought a legacy V5 main board

I searched for it before posting but didn’t find it. I’m making my own right now, while also trying to learn PCB design and CAD, so it’s going a bit slower than intended. All the best for your build.

I am not sure that latest rpi 5 active cooling is that big drawback. My zynthian with Rpi5 is all the time switched on on my deskt and very close to me. Fan is only switched on when playing something demanding but then it is not important because you can’t hear it while playing. When I am not playing it switches off so room is quite. Another, good thing about rpi5 active cooling is that it is now mounted on a different holes so it does not use holes for standard 4 standoffs. I mount mine rpi to mini v2 pcb with 16mm standoffs so that there is enough space for air to flow. For 16mm stand-off I need female pin header with 2 spacers on mini v2 pcb. You can go even further and use a female pin header with 3 spacers and have 18.5mm space in between rpi and PCB but then you increase a height of case for another 2.5mm.

Can a zynthian build be more clean than this and that is self sufficient to plug your preferred midi device and play and fully control it with all 20 buttons.
I have printed this today to test latest mini v2 case design. Assemble takes 10mins now. I prefer more fully printed case than enclosure around pcb top facia.
I have uploaded different case and enclosure types for mini v2 into my fork of zynthian-case here:
I will issue pull request so that all is merged with zynthian-case GitHub.
Designs include openings for rpi 4 and rpi 5 and each with different rpi standoff length. This one assembled today has 18.5mm stand-offs (rpi 5 is attached to 40pin female header with 3 spacers) so there is enough air between rpi and pcb for ventilation.
I am happy with mini v2 build now so it is time for me to move on to mini v3.

Mini3 needs to have a PEZ dispenser. I feel it’s the one thing consistently missing from the main kit.

Congrats. This is just terrific!

great job @stojos and thank you very much.
Your work is a huge contrib to the Zynthian ecosystem for making it fairly accessible for newcomers (in terms of price and also in hand building needed skills).
Completed assembling the 5.1 kit with included RPi5.
The only problem I had was that I inserted the display cable into the RPi backwards (the cable had no blue side as mentioned in the Wiki build instructions)
After taking a bunch of it apart so I could insert the display cable properly, it worked.
I updated the Wiki build instructions to be much more clear about how to connect the display cable to the RPi. I also added some info on what to expect on the screen when booting the first time.
Everything seems to be working fine now. Thanks for all your work creating this!
I’ll be adding some more documentation to the wiki as I learn to use features that are undocumented there.

hello friends, this is definitely a “mix” of projects in this zynthian.
It still lacks the internal 5V power supply, and an audio noise filter, and Bluetooth audio. including cell phone support…

super clean DIY build and really clever setup with the phone on the top
well done, congrats
It looks totaly noize ready to me 
As is, this is not a native feature of Zynthian I guess, but should be doable. What are your plans ?
Well, the PCB board with Bluetooth and noise filter should arrive next week… then I’ll show you the final result. It’s worth remembering that this project has a small two-channel mixer.
Hi all, first of all Zynthian is amazing, I really love it.
I made my own box with a RPI4, MCP23017 encoders, Innomaker - PCM5142 and a touch screen.
I like the idea of looking inside the box 
and in the future I would like to experiment with circuit sculpture with the goal of removing the wires with something aesthetically more pleasant
Anyway, a lot of fun and now music!
Thank you, Andrea

That is really cool! Well done @avitaletti and welcome to this wonderfully kind and loving community. I’m glad to hear such positive feedback from you and look forward to hearing some sound you create with your new toy.
WHITE OR BLACK?
Hi everyone, I’m testing the Zynthian RPI 4 with the internal audio interface of the Roland GO KEYS 5, it recognized its interface perfectly.
I noticed a slight slowness in the Zynthian system, but it’s usable, I intend to build a lighter and cheaper version of the Zynthian.

Looks gorgeous.
PI5 would seem the way to go.

PI5 parece ser o caminho a seguir.
[/quote]friend, you are right!
