Chameleon Invasion

So I’ve been on quite the shopping rampage lately ordering some parts, several books and I just now ordered a few new dev. kits that I can’t wait to play with! As I was reading my new issue of Circuit Cellar I saw an article about a development board that contains an Atmel AVR 328P *AND* a Parallax Propeller. I’ve been wanting to play with the propeller for quite some time now, but just never got around to ordering one. The board is from Nurve Networks and it is called the Chameleon.

I should also note that it also comes with a PIC in place of the AVR, but the fact that the AVR comes pre-loaded with the Arduino bootloader and that there are already Arduino libraries for the platform looks really interesting! I have ordered two boards and I think I’m going to try an experiment to create the same project on both boards, one using the Arduino bootloader/IDE/libraries and one without to post a comparison of the time required to complete each.

Some of the board’s features include:

  • 2 Processors for a total of 9 processing cores
  • 1MB Flash, 64K EEPROM
  • NTSC/PAL video output as well as VGA interface
  • Audio out
  • PS2 port for interfacing with keyboard/mouse

Take into account that the entire package is currently going for less than $60 and it looks even more impressive. As always, I’ll post on any projects/experiences once I get them in 😀

Cheers!

DS Touch Screen Project

So my SparkFun order came in today. I received some IR LEDs, some IR ICs w/ EEPROM that can record IR signals from any remote, store them and then perform an action when they are detected again (by controlling digital output pins). I also got some Nintendo DS touchscreens and breakout boards for them and a few other little toys.

An Arduino Apology

I’ll admit it… I trash talked the Arduino platform. I’ll also admit that any comments I made were entirely unfounded. Like other people I know, I equated the Arduino platform’s simplicity with “restrictiveness” and “cheesyness.” I don’t know why, but I kind of viewed it as the “VB” of microcontroller programming (ie: good for n00bs, but really bad otherwise). I used to laugh at people who had their little toolboxes with their cute cut-to-length wires and kits.
