The Fantastic Muscle Music Machine Experiment Trilogy

Music is a passion, an art, a science, but maybe most importantly… music is fun! Variations of “electronic instruments” can be traced back as early as the late 1700s, but it is no exaggeration to say that the biggest breakthrough was the invention of Synthesizers in the 1950s. This marriage of music and electrical engineering undoubtedly has inspired and continues to inspire people to learn more about both the science of electricity and music.

Our newest trilogy of experiments is designed to get any student or hobbyist experimenting and developing with a new kind of musical interface…. a Brain-Music Interface! Electrical signals from your brain and your muscles will become the music you hear. Check out the experiments below!

Making Music with a Muscle

This lab is an excellent introduction to Arduino Programming and to Modifying Pre-Written Code. You and your students will begin by uploading new code to the Muscle SpikerShield, then we’ll show you just how to modify it so you can play your own musical creations!

Experiment: Making Music with a Muscle

The Multiple Music Muscle Generator

Use the Muscle SpikerShield Pro to control up to six independent outputs. In this case, it will be musical tones. Time to generate music by moving your body. Your dancing makes the melody and the beat!

Then experiment and change the notes and tones your muscles will generate.

Experiment: The Multiple Muscle Music Generator

The MIDI Muscle Machine

The prophecy is fulfilled, and you will become the music and the movement! Control a real musical instrument with your muscles via the MIDI interface. Now you can interface your own nervous system with real electronic instruments! Invent new styles and forms of music!

See it featured on the Chilean show El Hormiguero where guest Antonio Banderas gets to see how its done!

The Tools to Make it Possible


You are in control… literally! Now you can control machines and electronics of your Arduino projects with the electrical activity of your muscles! What will you create?

Take your DIY biohacker projects to the next level with the Muscle SpikerShield Pro, a Human-Machine-Interface device that allows you to record EMG signals from up to six muscles at a time!

First Place at Science Fair for Student using BYB Gear

My name is Azrin Khan and I am currently a junior (11th grade) in Francisco Bravo Medical Magnet Senior High School in California. My purpose is to build a device which will alert humans when they are going to have muscle cramps, and it will keep a record of the intensity of the cramp and how many times it happened. In addition to that, I am also going to build an app where all the data will be stored, and their doctor will also have access to the data so that any health issues can be determined and kept in control. This is an idea I got after watching all the diseases that have muscle cramps as their symptoms, and I believe having muscle cramps should not be neglected but it should be greatly taken care of and kept track of.

I asked Backyard Brains if they could help me with my project, and so I started to work with their Muscle SpikerShield. At the Bravo/USC Science and Engineering Fair last month, I won First Place in my category which was Mathematics and Computer Sciences.

Engineering Goal

The goal of this project was to construct a device which will assist epileptics to be alerted of their condition, and alert others around them to be on the lookout for danger when muscles contract abnormally in the body. Also, code to interpret the data recorded from the device into a human understandable language and using a live graph to plot real-time data which will be useful to both the individual and doctors and other professionals to be updated on the most recent conditions. This is the very first device that uses the electrical potential measured from muscle contraction to identify muscle cramps.

Overview of Project

This project uses an alarming device which sounds whenever muscles contract abnormally in a person’s body so that others nearby can also be aware of the patient’s condition. To test if the device was working, I tested on Lumbricus Terrestris (earthworms) and measured the electrical potential for 30 seconds on each earthworm. The device can also record the electrical potential every second so that the recorded information can be shared with their doctors and other professionals through these updates regarding their conditions. The live graph uses Python 2.7.15, and Python IDLE was used as the developing environment. Piezo Speakers connected to the Arduino Uno and Backyard Brains’ Muscle SpikerShield combination device alarms as soon as the electrical potential units reach 95 to 100. In the future, I would like to use an app to make the live graph available to doctors so that they can keep up with their patient’s health.

Results

In conclusion, my device is functioning properly and in addition to my device, I’ve also designed a shirt with a pocket on the left sleeve that patients can use to hold their devices (see below). The Bravo/USC Science and Engineering Fair 2019 was a huge success for me. In my category, Computer Science and Mathematics, there were very impressive projects; someone used a drone to construct a gas sensor, while another participant coded a website that is designed to help people with OCD. I had a total of three judges who interviewed me, and two of the judges were professors from the KECK School of Medicine of USC and another judge was a lab PI also from the KECK School of Medicine of USC.

DIY Neuroprosthetics: A Third Thumb?

The Third Thumb

An 8th Grader’s Exploration in DIY Neuroprosthetics

Several months ago, a crowdfunded classroom got their hands on several of our neuroprosthetic kits – like The Claw and the Muscle SpikerShield Bundle. This allowed students in Nokomis Regional schools to begin experimenting with hands-on neuroscience experiments! One of the students, 8th grader Kaiden K., was interested in developing a prosthetic, but his project had a twist question: What if we had a third thumb?

The Third Thumb

Kaiden’s project is twofold: First, it is a project on the history of prosthetics. From wooden hands to mechanical prosthetics, and now modern, low-cost DIY prosthetics, there have been a lot of remarkable developments along the way as we strive to create new opportunities for people to bring mobility and ability into their lives.
Using a 3D printer and the tools his teacher had crowdsourced on Donor’s Choose, Kaiden was able to develop a neuroprosthetic which anyone can plug into and control with their brain!
By recording from their muscles, Kaiden is able to put other students at the science fair in control of the prosthetic hand.
The second part of the project is still underway: developing a neuroprosthetic which anyone can wear which augments typical human ability and mobility, by adding the third thumb! To put it fantastically: Kaiden is developing cybernetic human enhancements. Literally, 8th graders are contributing to helping us become cyborgs! Too cool.

In an example of parallel, historic discovery – Kaiden had the idea for an extra thumb and began his RnD… then just like many other great minds, discovered he wasn’t the only one doing this work!

This idea has been explored by prosthetic designer Dani Clode – she gave a TEDx talk which is also a great watch!

See her TEDx talk here to learn more about the Third Thumb project.

We’re excited to see Kaiden further refine and develop his project. Kaiden wants to investigate multiple degrees of freedom, perhaps 2-axis control, and see what he can develop. We’ll be sure to update you as he continues experimenting!
