Aaaaaages ago SWMBO's brother gave me a Roberts Radio to convert to an ipod dock. I never actually got around to it so I decided it would make an ideal Christmas pressie. This is a photo of the finished article:

I was given a dead Roberts Radio. The speaker was mullered and the guts were already ripped out so I just had an empty shell to work with.
Inside I've fitted it with a 4" 20W twin-cone Pioneer speaker to replace the pathetic offering it came with (probably). The amplifier is a 1W per channel TDA2822 which I've found you can overdrive quite easily with a few more volts on the supply side, powered by 4 AA batteries:

The amp is on the left soldered up on strip board, really basic reliable stuff which can be upgraded later for something a bit more manly if needed. Battery box is mounted on the door:

On the back is the on-off switch and the headphone cable:

I really wanted to have it as a 'dock' to slot the ipod into but I couldn't find a suitable ipod dock unit with a volume control so I opted to just use a cable. I'll keep looking because I have another old radio to convert and the MDF panel I made for the top of this one is easy enough to modify.
Hope you like :)
