Gary’s Wifi Radio Project

Tuesday, January 19th, 2010

Gary Dion (N4TXI) created a Wifi Radio to match his entertainment center.  His project is inspired by my original Wifi Radio project and shares several of the same parts (such as the Asus WL-520gU wireless router) and design philosophy.

Interesting features of Gary’s version of the radio:

  • Very cool 4 line VFD display allows more information to be shown at once (and it’s blue!)
  • AVR sends actual shell commands to the router, which allows the serial console to remain enabled for debugging/other purposes – brilliant!
  • Nice custom PCB for the ATmega8 microcontroller
  • Rotary encoder and significantly more advanced control menus
  • IR remote control support!

More details, photos, and source code are available on Gary’s site.

Thanks to the Make: blog for bringing this project to my attention!

2009 in Review

Thursday, December 31st, 2009

Wow, 2010 came a lot quicker than I expected!  With one day to spare, here’s a brief look back at some of the highlights of 2009 here at mightyohm.com.

DIY PID-Controlled Soldering Hotplate:

PID Controlled Hotplate

I needed a hotplate for surface mount soldering, so I built one from scratch using a milled block of aluminum, a 500W cartridge heater, and a surplus PID controller.  Some of my favorite DIY projects have been building my own tools, and this one is a great example.

The AVR HV Rescue Shield:

AVR HV Rescue Shield Layout

This year saw the release of my first electronics kit, the AVR HV Rescue Shield.  Designed in response to my own experience accidentally setting the RSTDISBL fuse on an AVR microcontroller, the AVR HV Rescue Shield has helped many microcontroller enthusiasts around the world rescue their otherwise crippled, stuck, or deaf AVR’s.

My Wifi Radio Project:

Wifi Radio project on Engadget!

After planning out the project and completing a good chunk of the software in 2008, most of the construction of my Wifi Radio project occurred in the early part of 2009.  I put the finishing touches on the radio for the 2009 Bay Area Maker Faire.  Around the same time the project also made it onto Engadget (and a bunch of other blogs as well).  This project continues to be one of the most popular projects on the site and has inspired several other projects based on the Asus WL-520gU wireless router, including an extension to the Adafruit Industries Tweet-a-Watt.

This brings me to:

Notacon 6:

In April I flew out to Cleveland and gave a talk about Hacking the Asus WL-520gU Wireless Router at Notacon 6.   The con was a huge amount of fun but reminded me just how much work it is to give a talk.  I met lots of cool people there, including George Sanger and Jeri Ellsworth, aka The Fatman and Circuit Girl.

By the way, the submission deadline for talks at Notacon 7 closes on January 31st!

DIY TiVo IR Blaster:

My DIY TiVo IR Blaster was a simple hack constructed in an hour entirely out of parts I already had in the lab.  The best part is that eight months later, it’s still working flawlessly.  Like any good hack, this one is cheap, simple, and just works.

Harrison’s Box:

Harrison's Box

This project, codenamed “Harrison’s Box“, was a collaboration with my wife Kylie and my father-in-law Bill to build an “electronic box” to give to my nephew Harrison’s on his first birthday.  We added as many switches, knobs, and lights as we could.  Harrison loved it!

Retro Wireless Handset / Make Magazine:

Charging

I originally posted about my Bluetooth Handset Hack back in November of 2008, but it took exactly one year for the article I wrote about it to finally be published in Make: magazine volume 20.  I just learned that my Retro Wireless Handset will be featured in an upcoming episode of the Make: Weekend Projects podcast.  Cool!

Those are some of the highlights of 2009.  I hope to bring more cool projects, hacks, and kits to you in 2010!

Lastly, Happy New Year and a sincere thanks to everyone who has been reading the blog, leaving comments, buying kits, or supporting the site in some way over the past year!

Help is available on the Discussion Forums!

David Nichols’ Tweetster, a wireless Twitter display

Tuesday, July 28th, 2009

David Nichols made this awesome wireless twitter display by combining a hacked Asus WL-520gU wireless router with a Sparkfun serial-enabled LCD display.  The router is running the same OpenWrt distribution I used for my Wifi Radio project, plus a USB thumbdrive that provides some additional flash storage space.  I really like the custom laser cut base that holds the LCD display and the router!

For more pics and info, check out David’s flickr set for the project.

My Wifi Radio Station Playlist

Thursday, July 2nd, 2009

A few people have asked me about the playlist that ships with the interface.sh script for my Wifi Radio project.

I’ve actually modified my playlist slightly, so here’s what I’m currently listening to.  Click on the links to open each station in Winamp or iTunes.

1. SLAY Radio

http://slayradio.org/tune_in.php/128kbps/listen.m3u

SLAY Radio is dedicated to playing original and remixed tunes from the Commodore 64.  Regular live shows that feature guest DJs who select and play their favorite C64 tunes, plus occasionally some stuff from the Amiga and other platforms.  SLAY Radio inspired me to dust off my old sid and mod files.  Does it get any better than this?

This cool banner shows what song is currently playing.  Click to visit their site.

2. KCRW Simulcast
