Modulin – DIY with Raspberry pi and Sunvox

Hey, have you ever heard of a Modulin? It is a modular synthesizer that is played like a violin via ribbon controller. Created by Martin Molin from the band Wintergatan #genius. As soon as I ever heard and saw the Modulin I wanted to make one but had no idea how to go about it. Untill…

Martin released this video How does THE MODULIN work? – DIY Music Instrument and I got an idea, what about a raspberry pi?

Modular synthesizer.
So I started googling (raspberry pi modular synthesizer) and was introduced to the Moonbox project and Sunvox.

So now all I need is a ribbon controller, a frame and a modulation/pitch wheel.

Ribbon controller.
Finding a ready to go ribbon controller with the features I am looking for on a budget is a real trick. After much searching I found the one string project with was kickstarted and can be purchased in diy kit form or a ready to go at straytechnologies for around $100.

Now for the brain.
I went to my favorite computer store and got a raspberry pi 3 b a micro sd card and a 7in touch screen. i needed a case for it. As i was looking into cases to 3d print on thingiverse i saw a post on Instagram from Adafruit for their 7in Portable Raspberry Pi Multi-Touch Tablet. Perfect, exactly what I needed.

Pitch wheel/Modulation
For the modulation and pitch wheel i have been looking into parts and possibly a cheap keyboard with the features i need to hack into what i need. looking im thinking my best option for this would be to midiplus AKM320 midiplus MIDI Keyboard Controller. I will get one when i can and take it apart if I cant find a cheaper alternative.

Updates: March 25th 2017
As of today, i have the case printed and assembled with Rasbian with Sunvox for pi running on it and using a computer keyboard as the input, until I can get the one string and the modulation wheels.

I have made the frame installed the one String ribbon controller and mounted the raspberrypi and screen in the frame. i can get the Modulin to interface with garageband on my mac using some additional software to convert the midi over usb to a standard midi port. I have been having issues doing the same thing on the raspberry pi. My solution for now will be to use a midi to usb cable to convert the midi signal to something the pi can understand. I also started designing the front plate that will hold the volume and modulation wheels. I’m sure I will be going through multiple versions.

My Music plans for 2017

Hey all!

I have been failing when it comes to being creative with music recently. So I decided to set some goals for myself. My goal is to create 3 post-space rock albums. To achieve this I will spend a month writing for the first album then spend the next 5-6 months recording. (rinse and repeat) I will be documenting my progress on my new music youtube channel. (I would love for you to subscribe and give feedback)

Also I started a bandcamp page so I can make my albums avalable when they are done.

The albums will tell the story of a man on a journey to leave everything he knows behind to discover and settle a new planet.

The band name is Matt Davis A.H.A.R.S. and the first album will be self-titled.

September inmoov update 2016

It’s now September and time for another inmoov progress update. The transparent red I was using finally came back in stock for a day or so, and I was able to get another roll. That allowed me to print the right arm and the rest of the head parts. I need 2 or three more to print everything in it that I need.

I found a windows 10 tablet from banggood on sale! and got 2 high torque servos to start fitting in. also, I ordered two servo hats for the arduinos from amazon.

I’m hoping that I can find some time to dive into the programming side of this project soon. Having a designated pc should help.

this project is really starting to come together.


August Inmoov update

Im back to printing my Inmoov. I just finished printing all the torso pieces and I am moving on to the shoulders. Also I ordered a 360 Kinect to play with. I’m concidering getting a second printer to try and speed up the printing  process. I downloaded the script repository and have started playing with the script inmoov3-full. I still have a ton to do and learn but it’s coming along.

3D printed headphones that rock!

I have had these studio sony headphones that were a little worse for wear. I hung on to them cause the guts were still in great condition. This last weekend I decided I was going to fix them up. I had the ear pads from a $5 pair of headphones my kids have long since destroyed. Thanks to CarryTheWhat and their design my old headphones now have a new life.

This project was an easy print. The assembly was fairly simple. Everything fit together great. I only had to slightly modify the earcups so i wouldn’t have to desolder and resolder the wires.

I went to school for graphic design. My wife and kids have always challenged me to be the best I can be. I went from stocking potato chips to driving a school bus to finally landing a job in the design business. This path has really challenged me to grow in my creative and technical skills, and has allowed me to expand my talents. I’m grateful for the opportunity to provide graphic and video services to clients all over central Ohio.

Thank you for taking the time to browse my website.

Sk450 Deadcat quad project

Back in 2014 I got my Sk450. It came in a kit from hobbyking. ARF. With that purchase I ordered the deadcat frame, and a servo gimbal for an action camera and a couple batteries. I bought a used go pro on ebay and mounted it to the top. I didn’t know how to go about controlling the gimbal at first. over the past two years I have tweaked the settings. Added and upgraded, and now I have a really solid flying machine.

When I finally made the dead cat conversion, all of a sudden I was only getting 3 minute flights. i was used to 6-10 minutes. I didn’t know if my motors were wearing out or if something electrical was wrong. the first thing I did was order some large carbon fiber blades on amazon. this solved my problems with lift and flight time. I added a low battery alarm after one flight where I flew till I was out of battery and broke some stuff.

My first fpv flight was around my back yard on a snowy afternoon. The flight was a success but landing in the snow fried my kk2 board and my speed controllers. Parking me for a while, till parts could be ordered.

After this flight I looked into flashing the kk2 board, setting up the gimbal and extending the landing legs so that the gimbal wouldn’t touch the ground. Also when I added the gimbal to the copter I could no longer use the gopro for the fpv feed so I got a on board security camera. one advantage of a camera like this is it does very well in low lighting.

I have been flying when I can, which unfortunately is not as often as I would like. The sk450 dead cat is a great transition from toys to the real deal.
