As I mentioned last week, Adafruit Industries is hacking the Asus WL-520gU wireless router to talk to the Tweet-a-Watt.
Their hack is based on the work I did to create my Wifi Radio project.
Check out the video below to learn more about their cool hack!
Head on over to the new MightyOhm.com Forums to discuss projects from the blog and chat with other members of our small (but awesome) community!
At the moment there are forums for:
Ladyada of Adafruit Industries created the Tweet-a-Watt to monitor energy usage in her apartment.
Each Tweet-a-Watt device contains some power monitoring electronics and an Xbee module. The Xbee modules relay energy usage data for each Tweet-a-Watt back to a single receiver, which collects the data.
In staying with the overall green theme of the project, Ladyada used an Asus Wl-520gU wireless router to control the receiver and collect data. This is the same router I used for my Wifi Radio project! The WL-520gU consumes ~5W and has enough horsepower to run the python data acquisition scripts while still acting as a cablemodem gateway.

This is my 100th post to the blog.
When I started blogging in July of last year I wasn’t sure what I would post about or where all of this would go. Eight months later, the blog has exceeded my expectations in many (and many unexpected) ways. The major driving force behind this blog has always been my desire to share my projects and my passion for electronics with the world, in addition to (hopefully) inspiring some other people to do cool things with electronics as well.
My favorite post? Definitely the Arduino-based AVR High Voltage Programmer. I never expected such a simple circuit to help so many people. There has been so much ongoing interest in this project that I am putting together an Arduino shield kit based on the original design. The kit features a slick double-sided PCB and an integrated 5 to 12V step up converter so you don’t need an external 12V supply to use the programmer. More details very soon!
Tony created this awesome Google Sketchup model of an enclosure for my Wifi Radio project. After I made a very crude first draft, Tony took my design and turned it into something that is sort of modern, sort of retro. Perfect!
In other news, there is a Dorkbot SF meeting tonight at Parisoma at 7:30PM. Arrive early to get a seat! Details at dorkbot-sf.
Hal created a neat project by taking parts of my Wifi Radio project and repurposing them to do something completely different. His Standalone Weather Station changes the color of an LED based on the weather forecast for tomorrow. If temperatures are trending warmer, the color changes towards red. Colder – blue.
His project is very well documented and includes code for both the ATmega168-based circuit that drives the LED using PWM and the shell script on the router that communicates with Weather Underground to get the forecast.
Nice work, Hal!
