pedalSHIELD MEGA is a programmable guitar pedal for your Arduino

If you want to create new guitar sounds without having to redo your pedal wiring every single time, the pedalSHIELD MEGA from ElectroSmash could be just what you’re looking for.

The pedalSHIELD MEGA takes input from a guitar via a standard ¼-inch cable, and uses an Arduino Mega to process the sounds to your liking. This new sound is then output using two PWM pins for a 16-bit resolution.

The device, which is available in kit form or as a PCB, sits on top of the Mega as an amazing looking shield. In addition to a 3PDT true bypass footswitch, a toggle switch, and two pushbuttons, the pedalSHIELD MEGA features an OLED display for visual feedback. Once assembled, all you need to do for an entirely unique sound is program your own effects in the Arduino IDE!

This shield that is placed on top of an Arduino Mega has three parts:

Analog Input Stage: The weak guitar signal is amplified and filtered, making it ready for the Arduino Mega ADC (Analog to Digital Converter).

Arduino Mega Board: It takes the digitalized waveform from the ADC and does all the DSP (Digital Signal Processing) creating effects (distortion, fuzz, volume, delay, etc).

 Output Stage: Once the new effected waveform is created inside the Arduino Mega board, this last stage takes it and using two combined PWMs generates the analog output signal.

You can find more details on the pedalSHIELD MEGA here, and see it in action below!

Control your computer sheet music with the PartitionsDuino

Performing an instrument well is hard enough, but flipping through sheet music while playing can slightly delay things in the best case, or can cause you to lose your concentration altogether. Music displayed on a computer is a similar story; however, Maxime Boudreau has a great solution using an Arduino Nano inside of a 3D-printed pedal assembly.

When set up with software found here, Boudreau’s DIY device allows you to control PDF sheet music on your laptop with the tap of a foot. While designed to work with a macOS app, there’s no reason something similar couldn’t be worked out under Windows or Linux as needed.

Pipe Your Way Through The Jams

Playing the bagpipes is an art that takes a significant effort to master, both in keeping a constant air supply through balancing blowstick and bag and in learning the finger positions on the chanter. This last task we are told requires constant finger practice, and a favorite place for this is on the steering wheel as a would-be piper drives. [DZL] therefore took this to the next level, placing touch sensors round a car steering wheel that could be interpreted by an Arduino Pro Mini to produce a passable facsimile of a set of bagpipes via an in-car FM transmitter. It lacks the drone pipes of the real thing, but how many other Škodas feature inbuilt piping?

We’ve covered an unexpected number of bagpipe projects over the years, but never had a close look at this rather fascinating musical instrument. If you are curious, the US Coast Guard pipe band has a short guide to its parts, and we’ve brought you a set of homemade pipes built from duct tape and PVC pipe. They may once have been claimed as an instrument of war, but they seem to also be a favorite instrument of hardware hackers.

Thanks [Sophi] for the tip.

YouTuber creates an organ out of 44 Furbies

If you think Furbies have become extinct, think again, as musical hacker “Look Mum No Computer” has decided to revive a number of them to create his own Furby Organ.

To make this horrifying yet awesome instrument, he placed 44—yes, 44—of these strange creatures on top of an organ frame with a keyboard and several dials, along with a switch labeled ominously as “collective awakening.”

Each individual Furby is controlled by two Arduino Nano boards, and as you might imagine, the whole project took a massive amount of work to wire things together. You can see the incredible results in the first video below, while the second gives a bit more background on the device’s origin.

Strumbot: The Guitar that Strums Itself

[Clare] isn’t the most musically inclined person, but she can strum a guitar. Thanks to a little help from an Arduino, she doesn’t even have to do that.

She built the strumbot, which handles the strumming hand duties of playing the guitar. While [Claire] does believe in her strumbot, she didn’t want to drill holes in her guitar, so hot glue and double-sided foam tape were the order of the day.

The business end of the strumbot is a micro servo. The servo moves two chopsticks and draws the pick across the strings. The tiny servo surprisingly does a great job getting the strings ringing. The only downside is the noise from the plastic gears when it’s really rocking out.

Strumbot’s user interface is a 3D-printed case with three buttons and three LEDs. Each button activates a different strum pattern in the Arduino’s programming. The LEDs indicate the currently active pattern. Everything is powered by a USB power pack, making this a self-contained hack.

[Clare] was able to code up some complex strum patterns, but the strumbot is still a bit limited in that it only holds three patterns. It’s good enough for her rendition of “Call Me Maybe”, which you can see in the video after the break. Sure, this is a simple project, not nearly as complex as some of the robotic guitar mods we’ve seen in the past. Still, it’s just the ticket for a fun evening or weekend project – especially if you’re introducing the Arduino to young coders. Music, hacking, and modding – what more could you ask for?

Create a beat by nodding your head

If you are really enjoying a song, you may start to bob your head to the tunes, but what if you could instead create actual music with this subtle movement? That’s exactly what Andrew Lee’s “Nod Bang” system accomplishes.

An accelerometer mounted to a pair of headphones senses nods in order to dictate the beat, while four 3D-printed arcade buttons are used to select which sounds will be played. An Arduino takes these inputs and passes them to a computer via a MIDI USB interface. The board also controls lights on the buttons for visual feedback.

Be sure to check it out in action below and read Lee’s entire write-up here.

Building an 8-step keyboard sequencer with Arduino

Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a sort of keyboard using input buttons.

This particular project employs a Nano for control, giving it a conveniently small form factor to fit inside your equipment.

Since the start of building modular synths, ive always been looking for an arduino powered sequencer. but never really happy with the projects that were about. because it was still menu dives and button combinations. which is not what you wanna be messing about with! you may aswell use a computer and a mouse ha.

Be sure to check out LOOK MUM NO COMPUTER’s entire build process and a demo of the keyboard sequencer in the video below. You can also find circuit diagrams and Arduino code in the project’s write-up here.

Ivy is a massive 240-step sequencer

Most musical sequencers use an array of buttons to control sounds played in 16 or perhaps 32 steps. As seen here, Moscow-based artist Dmitry Morozov (aka ::vtol::) created an installation called “Ivy” wth not 16, but 240!

The sequencer is based on an Arduino Mega along with 74HC40967 multiplexers to handle input from the 240 sliders arranged as controls for each step.  There’s also a bunch of WS2811 LEDs, which are driven by a Teensy board.

Ivy stretches five meters in length, and several “voices” represented by dots on the 1-dimensional light array travel both right and left at different speeds simultaneously. This allows it to be programmed in ways that wouldn’t be possible with traditionally-operated musical devices.

The project is created specially for Open Codes exhibition in ZKM center, dedicated to codes and programming in art. On one side, Ivy is a representation of an archaic method of electronic music programming for analog synthesizers. On the other side – gigantic scale and obsessive multiplication of simple primitive elements turns this project into an art installation, that is referring to the topic of graphic and physical organization of parameters in electronic music.

Music Box Plays “Still Alive” Thanks to Automated Hole Puncher

Custom hole punch and feed system

Most projects have one or two significant aspects in which custom work or clever execution is showcased, but this Music Box Hole Punching Machine by [Josh Sheldon] and his roommate [Matt] is a delight on many levels. Not only was custom hardware made to automate punching holes in long spools of paper for feeding through a music box, but a software front end to process MIDI files means that in a way, this project is really a MIDI-to-hand-cranked-music-box converter. What a time to be alive.

The hole punch is an entirely custom-made assembly, and as [Josh] observes, making a reliable hole punch turns out to be extremely challenging. Plenty of trial and error was involved, and the project’s documentation as well as an overview video go into plenty of detail. Don’t miss the music box version of “Still Alive”, either. Both are embedded below.

As [Josh] mentioned on his project page, he was inspired by a tutorial video showing how to punch music by hand. It led to this tool to take a MIDI file and cut the music paper out on a laser cutter, whereas [Josh] and [Matt] were inspired to automate the entire process in their own way.

For those of you who don’t think science should stop there, why not automate the creation of the music itself with the output of this Bach-emulating Recurring Neural Network?

Thanks to [Tim Trzepacz] for giving us a heads up on this delightful project!
