My Wifi radio project

Post by Neo2199 »

I just finished my wifi radio project. I used Mightyohm's wifi radio as reference whitch i modified. My wifi radio uses:
Case Genius center speaker
Asus:WL-320GE overclocked and modified to WL-520GU [edited]
Firmware compiled from kamikadze 8.09
Simple web platform from akula169
USB sound card PCM2704 modified slightly from diy4fun.blogspot.com
Rotary encoder volume control with MAX 5440
Digital audio switch with MAX 4762 to use this radio as speaker for computer
Modified akula169 20x4 display
Rotary encoder for selecting stations
Memory function for storing default station
Power up circuit
Cabel control headphone output
TDA2050 standard amplifier
Simple speaker protection

If anyone is interested in schematics or other sources please write, i can put them here, but now i have folder with all sources 370MB big and there is around 1000 files :D
I have worked on this project about 1 Year (Here I don't have proper tools or parts, saw its quite hard to finish something.)

Very impressive!!! :ugeek:

Can you please explain how you converted your 520GC to a 520GU? I know there are many people interested in this part.

Your finished radio looks great. I like your approach of using a center speaker as an enclosure.

Did you use an AVR microcontroller to interface with the rotary encoder and display, or some other chip?

Great project, thank you for sharing!

I have to apologise. A have 2 routers at home, and i looked in to a vrong box. I used WL 320 GE. Modifications are siple. Take out internal USB support, Overclock device if needed (I had to because of USB sound card). I read a lot of WL520GC and there is big problem with flash memory whitch can't be solved easly.
Yes, I used ATmega88 whitch is practicly thesame as ATmega168 (not in store in my country). AT mega 168 has more memory, but pinout is the same.

If You need any help or files, just ask. :) I have all project files backed up. But it is really little messy. Because I stored some source files whitch i modified. :) Or just some ideas from others.
