Do I need to replace the whole radio in my car?

I have a 1995 Toyota Corolla Conquest who's factory standard radio has just died (I think). It made a slight noise last night and cut out, and is now just flashing 01:00 on the clock with no buttons responding at all. I thought maybe the fuse had blown so I checked the radio fuse, but it doesn't look to have blown (something I suspected as a time keeps flashing on the display and I thought a blown fuse wouldn't allow any electronics to work). Also the cigarette lighter still works and that is connected/part of the radio fuse. [more inside]

How to get a plastic case made for a prototype product.

I am making a prototype of a consumer electronic device, the final product will be housed in plastic. I want to get a case made for the prototype that will resemble the final product. The case design is nothing complicated, essentially a rectangular box with some rounded corners and some holes for buttons, etc. I have designed the look of the outside of the case in adobe illustrator (top, bottom, front, rear and side views). The case will have a top shell and a bottom shell that fit together. What is the best way to go about getting maybe 2 cases made for prototypes? I am thinking either cnc or 3d printing, but I don't know what the best route to making a 3d model is from adobe illustrator or anything...

Please help me fix my iPod!

My wonderful iPod, going on nine years now, seems to have finally gotten to the point where I can't fix it anymore. I've replaced the hard drive, battery, hard drive cable, and logic board, and yet all it does is turn on, show the Apple logo, and turn off, repeating over and over. What else could be wrong, and how can I fix it? This is a B&W 4th gen iPod, originally 40 GB.

Making AppleTV work with an old TV

I have a Sony flatscreen TV: KLV-26HG2 LCD WEGA Color TV. It is a couple of years old. I would like to use Apple TV with it, but the Sony lacks the HDMI port that I need. Is there some sort of device that I could plug into the Sony that would have the HDMI port on the other end, so that I could then plug that into the Apple TV?

Snail trails on Garmin Nuvi 255W

Snail trails on Garmin Nuvi 255W. When out and about this device is now making pale blue 'snail trails' on the map tracking the car from A to B. It is working as it should otherwise. Does this mean that the device is on its way out? I checked some forums but could find any mention of this bizarre behavior.

Techie Birthday Present

My wife's birthday is coming up in early September and I need help finding a birthday present Fast as I'm going to be tied up the next couple weeks. She likes "toys" like remote control cars, helicopters, preferably that she can build herself. I got her a helicopter last year and a remote controlled car kit already so those ideas are out. She has a basic arduino kit and is always looking for a new project. She also likes cool gadgets for cooking, grilling. And she's into all kinds of music. She has an iPod, iPad, a Mac, a PC (several, actually). I'd like to keep it under $150 if possible. Your ideas would be most appreciated!

No seriously, a large print Arduino would be great...

Back in the days of yore, my (almost) 77 year old father was quite the geek and maker, but never a programmer. Fast- forward to today and he can no longer work on big building projects and spends much of his time with his iPad and TV. We've been discussing what kinds of "doing" projects he'd like to work on, but the obvious contender of an Arduino is maybe a little difficult as I'm not in Australia to help him out with the programming side of things. What great projects have you known senior geeks to get into? [more inside]
