ADC Conversion Time Comparison: Arduino Uno, Teensy 2.0, Teensy LC, Teensy 3.1
Comparison of analog conversion times (plus a bit of int swapping / checking) for:
• Arduino Uno (112 microseconds)
• Teensy 2.0 (60 microseconds)
• Teensy LC (16 microseconds)
• Teensy 3.1 (10 microseconds)

Vectrex Controller to USB HID Joystick
Made with a Teensy 2.0 in the Arduino IDE using the Teensyduino add-on. Download the code here.
The hardware set up is simple - the Vectrex controller end has nine pins. These should be connected to the Teensy as follows:
Vectrex pin 1 to Teensy digital pin 0
Vectrex pin 2 to Teensy digital pin 1
Vectrex pin 3 to Teensy digital pin 2
Vectrex pin 4 to Teensy digital pin 3
Vectrex pin 5 to Teensy analog pin 0
Vectrex pin 6 to Teensy analog pin 1
Vectrex pin 7 to Teensy 5V
Vectrex pin 8 to Teensy ground
Vectrex pin 9 to Teensy ground
The Teensy pinout can be found here. The Teensy should be set to joystick mode in the Arduino IDE under Tools > USB Type.

Interfacing Nintendo Amiibo with Ableton Live
The Max for Live device receives serial data from an Adafruit PN532 RFID shield and an Arduino Uno board. A MIDI note is generated using the last byte of the UID.

On Capturing PAL Game Cube Game Boy Player Footage and White Levels
The PAL Game Boy Player add-on for the Game Cube seems to output "whiter than white" levels for the composite output. I have tried this across multiple systems, cables, TV's etc, with the same result - completely washed out colours, with detail missing. One way of getting around this is to split the signal before it hits the display or capture device.
The first image below is the signal without being split, the second is the signal with a split going to a TV. The difference is huge.

Using a Hand Implant to Control Ableton Live
I've made a simple Max for Live device to get UID data from NFC chips such as the MiFare cards. This includes the Dangerous Things xNT hand implant chip.
The Max for Live device receives serial data from an Adafruit PN532 RFID shield and an Arduino Uno board. A MIDI note is generated using the last byte of the UID.
