Step 1: Find a Vintage Radio
Step 2: Buy an Internet Wi-Fi Radio and Take it Apart
Its not cheap though and goes for $300. I shopped around a little and was able to get one for $260. The other one out there is this one and is slightly cheaper www.reciva.com/joomla/index.php?page=shop.product_details... but I needed to be able to attach a knob to the volume control for the retro look as opposed to an iPod like volume control
Now take the radio apart
Step 3: Paint the Buttons
Step 5: Mount the Display
Step 6: Radio Grille Cloth
It turns out there is a web site called www.grillecloth.com/ that sells the same grille cloth patterns used in vintage radios. It costs about $10. They also include a nice guide on how to install which involes using spray on starch to make the cloth stiffer and then ironing it.
Once ironed, then spray some glue and glue it in.
