Omega Flight Computer

Delta Space Systems has developed a flight computer for launching rockets into high altitudes.

The Omega flight computer features 2 pyro channels, 2 servo outputs for thrust vector control, data logging, altitude measurements, and a gyroscope.  This latest version of their flight computer upgrades from using a Teensy 3.2 to a Teensy 3.5.  The increased processing power allows for additional data logging to make more accurate TVC (Thrust Vector Control) movements.  They were also able to eliminate the SD socket and flash chip from the design which contributed to a significant weight reduction.


UHF made TSynth, an awesome sounding four note polyphonic synthesizer.

Inspired by the Teensy-Synth series by Notes & Volts, UHF set out to make his own synthesizer using a Teensy 3.6, Audio Shield, and the Audio Library.


This synth is packed with features including four voice polyphony with two oscillators per voice.  Check out the forum post for a full list of features on this incredible project.


Bubble Punk

Mohit Bhoite made Bubble Punk, a nifty little sculpture to measure temperature and humidity.

Along with a Teensy-LC, the sculpture uses an Adafruit SHT32-D sensor breakout board, a vintage HP5052 7415 7 segment display, and a WS2812B LED to light it up.


Dean Blackketter’s Expansion Add-On for Teensy 4.0

Dean Blackketter created an add-on board which makes Teensy 4.0’s bottom-side pads available as a second row of normal pins!

It attaches underneath with castellated holes to solder to Teensy 4.0’s bottom-side pads.

If you’ve wanted a way to plug Teensy 4.0 into a sturdy through-hole socket and have access to all the signals, this looks like a really nice way to gain easy access to those bottom-side pads.

Dean shared this PCB on OSH Park and the Kicad files on Github.  Much more detail is available on Dean’s forum post and conversation which follows.

Lilla MIDI Expander

Sandro Grassia made Lilla, an neat, open source,  polyphonic MIDI expander.

Lilla’s controls features 12 rotary encoders and 8 pushbuttons and includes MIDI in, MIDI thru, and stereo out.  It can read files from and SD card as well as internal memory.

Additional details as well as code for the project can be found on GitHub.


Acoustic Levitator

Arvind Singh (forum user vindar) made an amazing acoustic levitator.

An acoustic levitator uses sound waves to levitate small objects, and until a few years ago were expensive to construct using Langevin horns that required tight tolerances and operate at high voltages.  Asier Marzo from Bristol University published a paper demonstrating how an acoustic levitator can be constructed from off the shelf parts and run on low-voltage.

Arvind built a levitator from an Instructible project based on an Arduino Nano, then decided to improve upon it by building one with a Teensy 3.2.  The processing power and memort of the Teensy 3.2 allowed for additional options to be added such as a TFT display and a joystick.

The casing was 3D printed using wood PLA then stained and varnished making for a beautiful device.

Code, schematics, and STL files are available on Git Hub.
