Im impressed!, thats a neat little project.

Do the heat sink get hot or warm at all Jay?

Hi Gav,

Thanks I must say again I'm amazed at the quality, the vid does it no justice

It did get very hot with a smaller heatsink running off my bench PSU, drew about 1/2 amp at 9v. Running on the little 9v supply with that sink ( stolen from an old laser printer ) it's cold to touch.

Thx

The next stage is to build another identical one, get a dual gang pot and an Ipod line in/charge desk stand thing.

Then I'll have a stereo ipod dock that will charge too.

I think I'll make the cabinet out of wood and make it look old fashioned ... maybe oak

A well made wood cabinet can look fantastic!
