Adafruit Eagle Library

January 21, 2010 by Mike Szczys 15 Comments

We love it when a PCB comes out right the first time. We’re careful enough with our designs that if something is wrong it’s usually a footprint problem, like we picked the wrong package for the components. Adafruit is helping to make the design process easier by sharing their Eagle library. Like the Eagle library version control we saw earlier in the month, this library is housed on github making it easy to stay up-to-date. The library includes many components (switches, crystals, IC’s, etc.), and fixes some prolbem-footprints, like 0805 surface mount pads.

Javascript Drum Machine

js-909

[Cameron Adams] recently appeared on a panel about JavaScript libraries. He represented the hard working coder that still wrote everything from scratch. He wanted to make something mindblowing for the audience. He ended up creating the JS-909 drum machine entirely in javascript without relying on libraries or flash. While he makes no claims of compatibility, it certainly is a nice bit of kit.

Tiny Arduino Ethernet Board

October 17, 2008 by Eliot 15 Comments

[sgk] built this tiny ethernet board to be used with the Arduino. It’s based on a WIZnet W5100 chip. The chip handles all of the TCP/IP communication and you talk to it via SPI. It’s compatible with the standard Arduino ethernet library. [sgk] hand soldered these boards including the 80pin LQFP main chip. His next project is to put the AVR and W5100 all on the same board. It sounds like he’ll use components larger than 1005 though.
