You need a '''RBPi3''' [https://www.raspberrypi.org/products/raspberry-pi-3-model-b Raspberry Pi 3 Model B] or [https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus Raspberry Pi 3 Model B+]

RBPi2 is not longer supported by official zynthian SD images. If you want to use a different RBPi version, you should rebuild your own SD image. Also, you can try with the experimental ZynthianOS images from here:

=== I just wrote my 16/32/64 GB SD card with a Zynthian image, but from Zynthian's console i only see a part of SD's total space and i've no free space left in the partition. How can i make available all the space on my SD Card? ===

''I know some people have experimented with audio input and were wondering if this would be added to the “official” Zynthian kit at some point and if so, how hard would it be to “upgrade” to it ?  

 

We are working for adding "audio input" to official Zynthian Kits. We hope to release the new kits by spring/summer of 2019.

=== Do you think Zynthian is for me? ===

It depends a lot. Building an official zynthian kit doesn't require soldering, only basic tinkering (plugging wires, screw-driving, etc.). The official zynthian software should run out-the-box and you shouldn't need to use the command line. That being said, being comfortable with Linux command line helps in solving problems

If you are comfortable with linux I think this is a great project and I do recommend it.

=== About Zynthian Security===

=== About Zynthian Security===

FYI, everything in Zynthian is executed as root user. The Pi user in the new PiOS images have sudo rights, so i don’t see a big security difference between the Gorgona and the PiOS images. PiOS is about automation and evolution, but currently it doesn’t improve security AFAIK.

Everybody wanting to connect his Zynthian to a “not secure” network (every network not controlled by himself should be considered “not secure” :wink: ) SHOULD CHANGE the default zynthian password. You can do that from the webconf tool.

Also, you have to understand that:

You also have to understand that:

* Although the Webconf Tool ask for the password, currently, it doesn’t use HTTPS, so your password could be sniffed by bad actors connected to the local network. That is specially true if you are using an ethernet cable or the old WEP Wifi protocol. If you are using WPA2 Wifi protocol in your 2 devices (Zynthian and your “computer”), then you should be protected against sniffers.
