David Kuder designed a SCSI device emulator with a Teensy 3.5 & NCR 5380:
SCSI target emulator based on the Teensy 3.5 (Kinetis MK64FX MCU) and classic NCR 5380 SCSI PHY. Supports multiple targets (Device IDs), LUNs, and device types. 3.2″ x 1.6″ footprint, optionally uses or provides bus termination power. 64×48 pixel OLED status display.

Paul Stoffregen of PJRC designed this shield as a Kickstarter reward earlier this year:
Please understand this shield has very limited software support at this time. However, Manitou’s early benchmarks show excellent performance we can someday hope to achieve as the software matures.

Charles McClelland created a Wi-Fi Connected Teensy:
The basic idea is that this board will connect to GPS, obtain a GPS fix and report its location to Ubidots.
Ubidots can then display this information in a number of ways including showing the location and the number of times the sensor had been moved that day

The various use cases may or may not require some or all of these pins. Here’s the most you can solder to the board in the simplest orientation
Most of these can be swapped, omitted, or assembled with small 1×3 connectors or whatever you have on hand. Otherwise, they can be purchased at Digikey or Adafruit

The Arduino has proved to be a great platform for electronics projects. The same goes for the Raspberry Pi. However, there are some projects that fall in the gap between these two options. Projects that need more memory or processing power than the ATmega microcontrollers have to offer, but not so much as to require […]
Catherine Holloway created this board to interface Mitutoyo dial indicators with a Teensy:
Teensy Mitutoyo InterfaceMitutoyo dial indicators can measure small displacements down to micron levels. I use them to calibrate motors used in quantum optics experiments, where every micron is several femtoseconds in the life of a photon.

Jarek Lupinski has posted an update for his Teensy E-Paper Shield project:
I finished writing a few helper functions that should get you up and running with the Epaper display shield. It can be easily integrated into a larger graphics library like Adafruit’s GFX for more intensive work.
