The project was inspired by a robotics competition. Matthew is a mentor for the team an wanted show how to have some fun with engineering. The hat uses 4 flexible 16×16 RGB LED panels, a Teensy 3.6, other miscellaneous parts, and LOTS of hot glue.
This imugr gallery has a pretty good write up on the assembly process.
Max Elliot was part of Unfolding Humanity, an amazing art installation at Burning Man this year.
This project was built by a team at the San Diego Geometry Lab. The sculpture is 10′ tall and unfolds to 40′ wide. It features 26 Teensy 3.2s with OctoWS2811 adapters and NRF24L01 radios. Mirrors on the inside of the structure create a kaleidoscopic effect.
Robert Archer has made an amazingly realistic 737-300 flight sim based on the IXEG 733 and X-Plane
Many Teensy’s are used in this build to preform various functions from simple switch inputs and stepper driver signals to more complex ARINC 429 data output. This incredible flight simulator is controlled with only 1 PC with 40 USB devices and two 50″ 4k TVs!
Robert has some great videos of the flight sim in action on his You Tube channel, including videos like this one showing a behind the scene look at the sim
This video shows Robert on the sim flying from Las Vegas to Santa Barbara. It’s hard to believe it’s not a real flight! It’s a long video, but the take off and landing are pretty cool to watch.
The MegaPixel is a DMX controller host board. It features 8 SPI feeds supporting up 32 universes or 5,440 pixels at at least 40 frames per second. This controller is a great tool for your holiday light show, LED stage shows, and more.
kbdhog created DIN-Uino, a prototyping and packaging project that makes your Teensy project into a neat, DIN-rail compatible device.
This board design works for the Teensy 3.6 and Teensy 3.5 and brings out all of the I/O pins to a DIN-rail compatible PCB.
Some of the features include:
* Industrial-compatible 24VDC (I’m aiming for a 12-25V safe operating range) power input with 5V/3.3V output. Connections via a 2-pin Phoenix 3.81mm header.
* Room at front edge of PCB for a maximum of 48 pluggable screw-terminals (Phoenix 3.81mm pitch).
* You can use single or double-stacked Phoenix-compatible headers, vertical or right-angle.
* Uncommitted right-angle pushbutton switch. You can wire it to RESET, or use it for some other function.
* 4-layer PCB design, with internal GND and POWER planes for power distribution.
* The POWER plane can be connected to 3.3V (default) or 5V (optional).
* Distributed power-vias allow easy access to the internal GND/PWR planes.
* On-board USB-A(host) or USB-B(device) connector, already wired to the Teensy’s native 5-pin USB header. The USB connectors are positioned at the edge, easily accessible even if an enclosed DIN-mount enclosure is utilized.
* Of course, this DIN-Uino Proto4 board is compatible with the related DIN-Uino mounting hardware and enclosure system.
Inspired by modern microcontrollers, Phillip wondered “With all of that processing power, could I create from the ground up a completely new 32bit 3D print engine that would improve upon the capabilities of the current 8 bit printer controllers?” This lead to the development of the Kynetic CNC software
Some of the current features include:
* Works with Delta, Cartesion and CoreXY machine configurations
* Stepper pulse rate at 100kHz
* Machine inverse kinematics computed at 4kHz
* My own trajectory planner with 100 block adaptive look ahead
* Program execution from SD card
* CPU usage is currently around 40% while printing on a Delta machine (Cartesian and CoreXY are roughly half of that)
