Schapiro Audio Skillet

Shapiro Audio have released the Skillet, a pro-audio MIDI controller built with two Teensy++ 2.0 boards. The Skillet is designed to be used with Avid Pro Tools.

The Skillet was designed to to control plugins in your DAW in a less fiddly, more interesting way. The device’s joysticks can control up to six parameters, and you can map them to any automatable plugin in Pro Tools. It also has dual touch-sensitive 100mm motorized faders and a nice-looking touchscreen menu system.

The Skillet uses two Teensy++ 2.0s: one to provide USB-MIDI output and convert all the control inputs into MIDI-based protocols, and the other to drive the touchscreen. If this sounds like something that would improve your audio production set up, you can get one on the Schapiro Audio website.


Classic Car Conversion Warning Light

Otmar runs Cafe Electric, a small company that builds electric vehicles.

As part of a recent classic car conversion they used a Teensy 3.6 and 0.96 inch color display to control a modified warning light.

Cafe Electric is a small company in Oregon that builds electric vehicles. Recently they shared details of a classic car conversion that they are working on in which they have used a Teensy 3.6, a custom PCB and an Adafruit OLED screen to replace a warning light.

The schematic, bill of materials and KiCad files have been published on the Cafe Electric website and you can download the board files or order yourself a PCB on the OSHPark website. You can also follow Otmar from Cafe Electric on Twitter for more updates on this and other electric vehicle projects.



Cuckoo Clock

Christof made a very cute cuckoo clock that tells the time with a ring of NeoPixel LEDs and marks the hour with a moving, singing wooden bird.

Christoph is from a region close to the Black Forest in Southern Germany, a region that is very well known for its beautiful, quirky cuckoo clocks. Traditionally these intricate clocks are mechanical, but Christoph’s version uses electronics and code.

This cuckoo clock uses a NeoPixel ring to display the time. On the hour, a servo opens the shutter, letting the bird peek out. The bird then sings, using a small speaker and the ever reliable LM386 chip to handle sounds stored on a SD card. The whole project is controlled by a Teensy 3.5.

For more information on the project, including more pictures and details of the libraries used, check out the original post by Christoph on the PJRC forum.

Lightsaber with Visual FX and Detachable Blade

Scott over at the Firebrand Forge has updated his spectacular lightsaber build using a Teensy 3.2 and a custom open course FX board.

There are many DIY lightsaber projects out there but Scott from The Firebrand Forge takes his version to the next level. The exterior is beautifully made with a detailed chrome handle and a vibrant, brightly lit blade that can be easily detached. Inside the handle is a Teensy 3.2 and a custom, open source FX board that controls the blade’s visual effects.

You can commission your own electronic lightsaber through The Firebrand Forge website, or if you want to have a go at making your own version, Scott has written up the project in detail, including wiring diagrams, a parts list and code.

You can read an article about this lightsaber at an earlier stage on our blog, or take a look at some more of the project details over at Hackaday.

Euclidean Rhythms Sequencer

Morton Kopf has created a beautiful sequencer that makes drum beats based on Euclidean rhythms.

Euclidean rhythms are an algorithmic way of making beats. Computer scientist Godried Toussaint discovered this technique in 2004, but the algorithm it is based on comes from Euclid, a mathematician in Ancient Greece. Euclid’s algorithm gave us a way of finding the divisor between two integers. Applied musically, that means that a musician could choose the number of steps in a sequence and the number of beats within that sequence, and the algorithm will decide where those beats fall. Layering Euclidean rhythms gives musicians an interesting way of creating intricate polyrhythms, leading to this technique becoming one of the more popular ways of making music with algorithms.

Morton Kopf has made a drum machine that uses these Euclidean rhythms in a four track, 16 step sequencer. It runs on a Teensy 3.5, also using four 16 LED Neopixel rings, four RGB rotary encoders and an LCD screen. Aside from the cool maths behind sequencing, one of best things about this project is the quirky, attractive casing Morton Kopf has made from some frosted perspex and an old port wine case.

If you want to have a go at making your own algorithmic rhythm machine, Morton Kopf has released build instructions on their website, plus you can find all the code for this project on their GitHub. You even also order a DIY kit for your modular synth rack if you don’t want to make the PCB or order the components yourself.


Satellite Uplink System for Remotely Operated Underwater Vehicle

Fabio Balzano has made an IOT satellite uplink system to send and receive data from and to his remotely operated underwater vehicle.

Scuba diver, sailor and robotics enthusiast Fabio Balzano needed to find a way to connect his remotely operated underwater vehicle (ROV) with the web to get its telemetry data, but as the planned deployment site was extremely remote, he was unable to rely on radio or even GSM as a way of sending the data. So, he designed and made a system using a Teensy and a Raspberry Pi that is able to send and receive data from and to the ROV via satellite link .

Balzano has written a number of build logs that follow the progress of this project over on, where you can also find descriptions of some of the tools he used and a schematic for the hardware in his prototype.


LED Pixel Strip Synced to Music with MIDI

This project by Experimental Experience seamlessly syncs music to light using an LED pixel strip, a Teensy 3.2 and MIDI.

Experimental Experience has made an impressive music visualisation project that synchronises a strip of LEDs with music based on MIDI. The software synthesizer used in this project plays audio at the same time as sending USB MIDI data via USB to a Teensy 3.2. The Teensy then uses note on/off and pitch information to control the LEDs, with different colors assigned to each of the 12 notes.

One of the extra special things about this project is how well documented it is. In a detailed, clearly-written article on their website, Experimental Experience provides a detailed tools and materials list, a guide to soldering and assembly, a guide to the software you’ll need to use plus all the code needed to run the project. You can also see more examples of this project working on the Experimental Experience YouTube channel, or see below for their energetic visualisation of Flight of the Bumblebee.
