Hi-Fi graped piano with Odroid-C1+

Working on the new Odroid-C1+ becomes more and more interesting. Having compiled the realtime kernel sources successfully on the C1+ I got the graped midi piano running together with the HiFi-Shield from hardkernel.com. You can plug the shield into your HiFi station at home or plug in your favorite headphones. Here I just use it together with simple bluetooth speaker which is connected with a stereo cable to the HiFi-Shield (which is a real waste of resources, I know. I just want to get a mobile HiFi Midi Graped Piano).

The graped piano can be connected with up to 48 grapes, but to keep the amount of wires low there is only a demonstration with 4 grapes (I’m not so hungry today).

To get the best conditions for my grapes I plugged a mini weather station (BME280) additionally on the breadboard. So, if it’s too hot, you can ask somebody to cool the location. Than your grapes will be fresh for a long, long time.

As third gimmick I plugged my touch(less) sensitive TouchDuino into the C1+ and can generate sounds with it by touching a DIY touchless sensor made from an old CD-cover and some aluminium foil.

Midi piano published in Odroid Magazine

Hi,

my article about the little Midi piano with a bunch of grapes made it into the august 2015 edition (page 26: FRUIT MIDI) of the  official ODROID MAGAZINE.  Next week I’ll publish the python sources to get it running quick  and easy.

Thanks to  all the guys of the ODROID MAGAZINE (esp. Rob Roy, Chief Editor of the Odroid Magazine) and Hardkernel.com for the excellent hardware.
