I'm quite excited to see the release of Manjaro ARM, and would be happy to help use, test, and contribute to it in any manner I can. As of now, I'd be happy to moderate/maintain a release.
I own several Raspberry Pis, including the 2, a Beaglebone Black, two new C.H.I.P. boards, and have two PINE64s (x64 ARM board) en route, so I'm familiar/interested in ARM devices. I prefer Arch Linux, so I sort of lean toward using the hardware devices that work with Arch. I use Manjaro as my daily desktop computer, and use it on friends/family member computers when Windows fails them.
As of now, I have a stand-alone Raspberry Pi/Arch Linux based music player appliance (digital boom box, if you will) that I built. It's operating off of Arch Linux, with MPD/MPC music server/client, with a DAC/amplifier in a wood box and some car speakers. has some physical buttons (Cherry MX White keyboard switches) that control play/pause/navigation set up on the GPIOs, and a web based interface that displays the current song playing and such. It has an LCD screen that displays a message, but isn't yet hooked up to display the current status of MPD. I'm not a developer, but used Python to do all the magic stuff, and use the device on a daily basis.
I've also started working on a Rasperry Pi/Arch based timer system, to control relays, lights, pumps, as a hydroponic grow controller. I have a basic timer function working, but is turnign into a project that's larger than I'm willing to do by myself.
My next plan is to build a portable PC using the PINE64 as a backbone with a custom ortholinear mechanical keyboard.
To date, I use Arch as my go-to RPI image, and love it, but use Manjaro as my daily driver desktop. I really like the idea of a Manjaro base for ARM, and would like to help in any way I can, to contribute to the community developing it.
I'm open minded to switch over to Manjaro, as I've had quite a good experience with my desktop verision, and believe that ARM devices/IoT are the future of computing.
Please contact me, so we can discuss this further.
