Using a Raspberry Pi 2 to make MIDI music

sampler_f

JosephEarnest has taken a Raspberry Pi 2, a USB digital-to-analogue converter (for sound output) and some other components soldered to stripboard to create a midi input/output device. The software is written in Python and cython and is available here. He’s made the whole thing open source on his website where you can read more and, perhaps, build it yourself. You can see a video of it in action below:

Great write-up of the Cambridge Raspberry Jam

Alex Eames of RasPi.TV has written a brilliant blog post all about CamJam which took place on Saturday, 6th June. It covers everything that was going on in the Marketplace and Show-and-Tell. I’ll be writing up my experience of the day very soon. I’m currently dog-proofing the garden in advance of getting a new puppy next week (hence why it’s been a little quiet on the bloggage front!) Read Alex’s write-up here.

Mini Raspberry Pi handheld computer

hacks_hero-astro-1

The Ruiz Brothers have published a new tutorial on the Adafruit website. This tutorial shows you how to create a handheld Raspberry Pi computer using a 3.5″ PiTFT screen, a mini wireless keyboard and a LIPO battery. It’s rather nifty and all the pieces go inside a 3D-printed case that is fully hinged. They do point out, however, that the 3.5″ screen is slower than the smaller screens available so it’s not much good on the video front. This is a shame as it would make a fantastic portable gaming console. Oh well, it’s a nice project anyway. Read more here.

Control a Sphero robot from the Raspberry Pi with Astro Pi

Another one from Richard Hayler. This time, he’s using Python on the Raspberry Pi to detect changes in the Astro Pi’s accelerometer and then translate that into commands he sends over bluetooth to a Sphero. The Sphero is a cute little ball-shaped robot with internal lighting that moves at great speed across the floor. You can read more about Richard’s experiment and see his code here and you can find out more about the Sphero from their website. You can see the whole thing in action in the video below:
