I’ve collected together as much information for you as I can. You’ll find it at http://ift.tt/2oDfz14. Make sure to register your details so I can see who can help me – I’ll send you stuff in return.
Good luck, everyone. We can do this!
BUILD A POLYRHYTHMIC SEQUENCER WITH RASPBERRY PI #piday #raspberrypi @Raspberry_Pi
This project shows you how to build a polyrhythmic sequencer and gives some good information on MIDI. Via MagPi:
Back in The MagPi #58 we showed you our Hexome simulator, running on a mobile device and controlling a sequence. It used concentric rings of trigger positions, starting with a ring of six with each subsequent ring having six more trigger positions. Now we take that basic idea, run with it, fall over, pick up the pieces, and assemble it into a universal polyrhythmic sequencer.
This article was written by Mike Cook and appears in The MagPi #61.
The basic concepts are the same, but this project gives us nearly unlimited flexibility. Each ring generates only one note, and those notes can be changed by mapping. However, almost everything else has changed. There are up to six rings in the sequence: each ring can have a maximum of 32 trigger positions, and can be individually muted. The big change is that each ring can have its own individual sound and volume, courtesy of MIDI.
MIDI stands for Musical Interface for Digital Instruments. It is a very old standard, but still as popular as ever. MIDI is a serial interface that sends messages between musical devices, which include instruments (like a keyboard), and sound modules that generate an audio signal. Some devices can combine the two categories in one device – the most popular being sound-generating keyboards.
Automatic Colormetric Water Tester #piday #raspberrypi @Raspberry_Pi
From Robogardens via hackster.io:
This describes the steps for making the automated water tester. The design has slightly changed since the initial post. The original design required printing a central stalk which all the parts attached to. The stalk was 310mm long, which meant that a large format printer was required. In addition, it was difficult to print it without warping. Based on some suggestions, I redesigned the tester to use a piece of 2020 extruded aluminum as the central stalk as well as in a few other parts that were long. The tester parts can now be printed on a printer with a 150mmx150mmx150mm build area.
The autotester is controlled through a web interface.
For convenience, I have broken the assembly into multiple parts:
- Overall guidance on printing the autotester
- Concept of operation
- Putting together the mixer stand
- Putting together the carousel assembly
- Putting together the stopper assembly
- Putting together the plunger assembly
- Putting together the camera mount
- Putting it all together
- Miscellaneous Parts
- Electronics
- Software
- Operation
Seen at #MakerFaire: Smart Spirometer, Pressure Sensor, and other DIY Medical Devices from @makerhealthco
Maker Health had some projects on display at the recent World Maker Faire. They describe themselves as:
At MakerHealth we believe in democratizing the tools of health making around the world. Whether it’s a hospital bed, smart pill bottle, or an improved triage mobile phone app we believe that design should be transparent, hackable, and enabling for everyone to be the designers and makers of their own healthcare solutions.
Two of the projects they showed included this pressure sensor which displays the applied pressure to the pad on the OLED FeatherWing add-on:
Also on display was this Smart Spirometer, a device used to monitor air flow into and out of a patient’s lungs – used to diagnose symptoms such as asthma or chronic obstructive pulmonary disease:
You can see the spirometer mounts into the base; the tabs around the edge (seen better below) swivel around and hold the spirometer in place. The VCNL4010 proximity sensor knows when the spirometer is or is not in place and if not, the device can activate a range of notification modules (light, or sound, or vibration) to notify the patient to initiate their spirometry test.

Vinyl Shelf Finder with Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi
via RaspberryPi.org
It is a truth universally acknowledged that a person in possession of a large record collection must be in want of a good shelving system. Valentin Galea has solved this problem by developing the Vinyl Shelf Finder. In this build, a web-based app directs a pan-and-tilt laser to point out your record of choice among your collection.
People love to collect stuff. Stamps; soap bars; Troll dolls; belly button fluff (no, really); if you can think of a tangible item, someone out there in the world is collecting it. Of course, every collector needs to solve two issues — which system to use for cataloguing and sorting their collection, and how to best retrieve items from it. This is where Valentin’s Vinyl Shelf Finder comes in.
Valentin keeps an online record of his vinyl collection using Discogs. He entered each LP’s shelf position into the record, and wrote a Node.js app to access the Discogs database. The mobile app has a GUI from which he chooses records based on their name and cover image. To build the hardware, he mounted a Pimoroni Pan-Tilt HAT on a Raspberry Pi, and affixed a laser pointer to the HAT. When he selects a record in the app, the pan-and-tilt laser moves to point out the LP’s location.

Access the contents of a .img file @Raspberry_Pi #PiDay #RaspberryPi
Handy tutorial from the folks over at the Pi Supply Maker Zone.
You may find yourself needing to backup your SD card for future reference or for posterity and fame. Whatever your reason there are several well documented ways you can do it.
In some case you might also want to be able to get things back from your backup and you then generally need to write it back to and SD card to do so.
Using a Linux distribution of your choice for your desktop system this article shows how to backup a card and access the contents of a .img file. I used Linux Mint but the procedure should be fairly similar for other distributions too.
A 3D Printed Batman: Arkham Knight Cosplay
To make a replica of a Bat-suit, you have to have the patience of Bruce Wayne. Naythero Productions, also known as Jack Raiden, clearly channeled some of the DC Comics hero’s ingenuity and tenaciousness when making this Batman: Arkham Knight costume. The armored suit is all about technology, also appropriate for the character. But unlike Bruce, Naythero Productions didn’t work alone. He teamed up with Replica Industries and KrayveN Cosplay. He said:
Fully made in 3d printing, à several days of sanding, car vinyl for thé carbon and black chrome effect, undersuit made in our studios Parallel Life Studios using screenprint technology, the chest is equiped with flex system to move just like in the game.
Check out more images of the costume’s evolution in this album.

The Possibilities of the Sense HAT @Raspberry_Pi #PiDay #RaspberryPi
via RaspberryPi.org
Did you realise the Sense HAT has been available for over two years now? Used by astronauts on the International Space Station, the exact same hardware is available to you on Earth. With a new Astro Pi challenge just launched, it’s time for a retrospective/roundup/inspiration post about this marvellous bit of kit.
We developed our scientific add-on board to be part of the Astro Pi computers we sent to the International Space Station with ESA astronaut Tim Peake. For a play-by-play of Astro Pi’s history, head to the blog archive.
It’s easy to begin exploring this device: take a look at our free Getting started with the Sense HAT resource, or use one of our Code Club Sense HAT projects. You don’t even need to own one in order to dive in. Emulators are available offline on Raspbian and online on Trinket.
Brainternet, Streaming Brain Waves with a Raspberry Pi #piday #raspberrypi @Raspberry_Pi
From the University of the Witwatersrand, Johannesburg via raspberry pi pod:
The “Brainternet” project streams brainwaves onto the internet. Essentially, it turns the brain into an Internet of Things (IoT) node on the World Wide Web. IoT refers to connecting any device with an on and off switch to the internet.
Brainternet works by converting electroencephalogram (EEG) signals (brain waves) in an open source brain live stream. A person wears a powered, mobile, internet accessible Emotiv EEG device for an extended period. During this time, the Emotiv transmits the EEG signals to a Raspberry Pi – a credit card sized little computer – live streams the signals to an application programming interface (code that allows software programmes to communicate), and displays data on a website that acts as a portal. This is currently an open website where the public can observe the individual’s brain activity.

Revitilizing a Wurlitzer Jukebox with a Raspberry Pi
via Raspberry Pi Pod
My father-in-law came across a free 1969 Wurlitzer 3100 Jukebox in March of 2017, in working condition, however the previous owner kept all of the original 45s. Essentially, leaving us with an empty cool looking speaker box. I had worked with an Arduino before to interface physical switches to digital operating systems via USB communication and figured I could use the same principals to hack this machine as well. The idea was to take an Arduino Mega and connect the jukebox buttons to the digital pins of the Mega, then use serial output to communicate with a media playback device, eventually settling on a Raspberry Pi Model 3.
The coding for this was the most difficult part, I had seen a few video’s and blog posts online for Arduino converted jukeboxes but never the actual code that I could dig into, until I found a git repository by Thomas Sprinkmeier. This became the foundation for a revitalized working jukebox with all new music! Once I had the code working on both the Arduino and Raspberry Pi, I then needed to make a custom button array and all new tactile jukebox selection switches since most of the 40+ year old originals were broken. I had to teach myself how to create silicone molds and transparent resin casting. Overall, I am very happy with this build, it works flawlessly and provides hours of music and interactivity just like the original jukeboxes from the 60s!

Kinetic Sculpture Uses Solar Wind Data and Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi
via Raspberry Pi Pod
Yiannis Kranidiotis has created a kinetic sculpture which reacts to live data of the solar wind. Called Cyma, which is Greek for ‘wave’, the sculpture works by the bottom plank being moved and then that movement being translated up through the stack along a nylon strand. The data is read and analysed by a Raspberry Pi, whilst the motor control for the bottom plank is controlled by an Arduino.
“The movement of the sculpture is driven in real time by live data of the solar wind. The strength of the wave movement (amplitude of the modulation) is controlled by the solar wind speed and the mode of waves (fundamental or harmonics) is controlled by north-south direction of the interplanetary magnetic field (Bz).”
