Thank you to forums user kerrylaw7307 for sending in instructions for an incredibly easy mod to the already-popular NeoPixel Painter project. Kerry’s mod adds a simple remote trigger to the circuit by jumping a JST connector to the trigger switch and adapting the receiver’s cable to the JST connector. Easy! Every remote will be a little different but Kerry explains how to decipher the receiver’s wiring and re-wire everything accordingly.

Adafruit NeoPixel Digital RGB LED Strip 144 LED – 1m Black – BLACK: These LED strips are even more fun and glowy. There are 144 RGB LEDs per meter, and you can control each LED individually! Yes, that’s right, this is the digitally-addressable type of LED strip. You can set the color of each LED’s red, green and blue component with 8-bit PWM precision (so 24-bit color per pixel). The LEDs are controlled by shift-registers that are chained up and down the strip so you can shorten or lengthen the strip. Only 1 digital out pin is required to send data. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you. Read more.
Arduino Uno R3 (Atmega328 – assembled): The Arduino Uno R3 is the latest version after the Duemilanove with an improved USB interface chip. Like the Duemilanove, it not only has an expanded shield header with a 3.3V reference and a RESET pin (which solves the problem of how to get to the RESET pin in a shield) AND a 500mA fuse to protect your computer’s USB port, but ALSO an automatic circuit to select USB or DC power without a jumper! The Uno is pin and code-compatible with the Duemilanove, Diecimilla and older Arduinos so all your shields, libraries, code will still work. The R3 (3rd revision) of the UNO has a few minor updates, with an upgrade to the USB interface chip and additional breakouts for the i2c pins and an IORef pin. Read more.
