MAKE presents: The LED

As you might already know, I am big of a LED fan, love all it’s light power and low power needed for that. While viewing the RSS from
HackZine I saw a great short video about the history of LEDs and a little about how to use them. I liked, and decided to share with you, hope you likes as much as I.

In case you would like to learn more about leds, you can visit HowStuffWorks and on Wikipedia.

Some projects I’ve used with leds:

Wordpress on the Apple macbook event

While following the coverage of Apple’s macbook event at gizmodo, I found one picture that I think is worth sharing,
they took a shot from people writing stuff about the event… And from few notebook screens I could see there, at least 3 using wordpress. Thumbs up WP!! :D

BTW, new macbook’s looks amazing, can’t wait to get one of those!!!

Another cool AVR Dev Board

Kyle Stewart built another cool Dev Board for the ATmega168/8 (same microcontroller used in arduino).
The news thing about this board, is that it have a “vertical approach”, leaving more space on the breadboard for other components, a excellent idea!

Some features:

  • Works with ATmega168 (and probably others)
  • 16MHz crystal
  • 5V and 3V regulators can supply power to breadboard
  • Plugs vertically into breadboard taking minimal space
  • ISP programmable
  • 1-wire debug can be used
  • Simple to build, no surface mount components

On kyle’s website you will find the schematic, eagle files and more.

Simple but well made ATmega8 Development board

In case you think a arduino board is too much for your ATmega Development, you should check this board made by yourITronics. Using the microcontroller`s internal clock, and programming using an ICSP cable you can start developing right now!

In the website you’ll find the scheme and the eagle file.

Say hello to Arduino’s big brother, Sanguino

And Zach Smith says: “I’m really really really excited to announce this new product. This one was directly conceived, funded, and produced here by the RRRF as a direct result of the kind souls who have supported us so far. To get to the meat, the Sanguino is a new microcontroller board inspired by the Arduino. We took the biggest baddest 40-pin DIP that atmel makes and made a board with it. Its based on the atmega644P which provides 64K of flash, 4K of ram, and 32 GPIO pins. The best part: its compatible with the Arduino software, which means all of your code should run on it no problem, and you can program it just as easily.

You can buy a kit from the RRRF for $25 or check out the Sanguino website.

I am totally going to get one!!!
