The picotux 100 is the world’s smallest Linux computer, only slightly larger (35mm×19mm×19mm) than an RJ45 connector. Inside, there is an ARM7 CPU at 55 MHz running uClinux kernel 2.4.27 and Busybox 1.0. Two communication interfaces are provided, 10/100 Mbit half/full duplex Ethernet and a serial port with up to 230.400 baud. Five additional lines can be used for either general input/output or serial handshaking.

This is my first build using an arduino microcontroller. I wanted to create a simple tone output device along the lines of the 555-based atari punk console, but using solely the mcu as the tone generator. Unfortunately, that was just too simple a task with a microcontroller to play with–it was done in about five minutes and my mind was already forging ahead with a bunch of stupid ideas.
Since coding the arduino is simple, I decided to set up eight tone “slots” and then sequence through them. A frequency knob would control the freq of each slot, and a separate tone duration control would allow me to get awesome eighties video game tones. Figuring out the component wiring wasn’t too tough once I’d figured out the basics of reading analog pots and digital switches.
I also thought it would be fun to add a 2 line x 16 character backlit LCD display. The one I used is from sparkfun electronics and includes a serial I/O board so writing to the display is super easy.

Solderless Breadboard Arduino Clone. Clique aqui para abrir…
Adafruit Industries is a small company that sells kits and parts for original, open source hardware electronics projects featured on www.ladyada.net as well as other cool open source tronix that I think are interesting and well-made.
All the projects are redesigned specifically to make it easy for beginners to make: nicely silkscreened circuit boards, through-hole parts whenever possible, extra large solder pads, etc. For some kits, you can purchase just the circuit board. To save paper, the easy-to-follow-with-lotsa-pictures instructions are all available online, at http://www.ladyada.net/make
I personally guarantee that these are more fun than making a blinking LED christmas tree.
