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.
Nick Anderson created this amazing light & sound show for Halloween.
The lighting and sound was composed with the Vixen3 software. The actual show runs using the Falcon Pi Player software on a Raspberry Pi 3, which transmits to a Teensy 3.2 and OctoWS2811 board to drive 2850 LEDs. Nick published his source code on github.
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.
