Build a Norns shield and got it working on a Raspi3 using an old SD card. Bought the PCB from Pursherman (12,26€, mail inc.) and the components from Digikey (70,74 € / +39,08€ import duties). All together 122,08€ for an entry to the Monome world. With import fees the cost for an official kit might have risen to ~280€ (+55€ for a Raspi). The build went smoothly. Previous SMD builds paved the way and I got all the components soldered within five hours. Made a case from scrap plywood by adapting these drawings. There is still some sanding to do and I have to source caps for the d-shaft p and the buttons. I’m occasional some trouble running Orca and a few other scripts. I believe that a faster SD card will fix the issues but I might eventually opt to get a Raspi3+ (the Raspi3 I’m using is from the Mazizone build which I’d like to keep running anyway). By enlarge everything seems to work well (including updates, running 201113).
For the simple synths (using a keystep for midi) and effects alone a good investment. I’m hoping to learn scripting and if everything feels good might work myself towards a crow. Norns feels feature packed and of course this being something I assembled, it will take time to develop a feel on what is a feature and what is a bug/build issue. Feels stable and powerful so far.
