PJRC Electronic Projects has come out with the $19 Teensy AVR development board. It uses the AT90USB162, which eliminates the need for a separate USB-to-TTL chip:
The Teensy is a complete USB-based microcontoller development system, featuring a 16 MHz AVR (AT90USB162) processor, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard “Mini-B” USB cable and a PC or Macintosh with a USB port.
Key Features:
- USB can be any type of device
- 21 I/O pins
- AVR processor, 16 MHz
- Single pushbutton programming
- 15.5K usable Flash memory
- HalkKay bootloader
- Free software tools for Mac OS X, Linux & Windows
- UART, SPI, 4 PWM, 2 timers
- Tiny size, 1.2 by 0.7 inch
- Very low cost, only $19

Craig continues his series of art-devices with I. M. Chip Blue, a curiously chatty box of electronics -
Here is I. M. Chip Blue, the fifth in my series of Enigma Gadgets. Like the others, it’s based on the Arudino microcontroller and uses the Quadravox QV300 speech module. The QV300 is programmed from the factory to speak 240 common technical terms including units of measure, numbers and colors. I. M. Chip Blue also contains a Memsic 2125 accelerometer. I have programmed it the device to speak nonsensical sentences based on a set of rules. The rules vary depending on the way the device is oriented.

Very cool – Franky wrote up a MIDI code library for use with Arduino. It handles the basic serial setup, interprets and filters incoming messages – also sets a pin to control the optocoupler chip (no worrying about incoming data messing with sketch uploads). Plus it handles MIDI out/thru transmissions as well – super helpful. – MIDI Library
