Now that my CNC machine is up and running, I am thinking of making some small bookshelf speakers for the workshop using a bluetooth audio board I have lying around.
I was going to use Apple Airplay (via an open source unix hack), but I've got dozens of Arduino's about the place and I should probably use some of them before I go buying more MCUs (my wife agrees! >.< ) - but of course, with this
I wanted to make some
Fostex 800E or
Auratone 5C-type clones and put a good, clean, small amplifier in with the bluetooth module.
So, bearing in mind I am new to all this electronic chicanery and I've heard that building an amp is a good project for n00bs, any recommendations on the kind of amp I should look at for my first from-scratch project? I am not averse to a kit, but have enough protoboard, etc. lying around that I can make something from components.
And speaking of components - they are short on the ground where I live - I have a few transistors round the place (1N4001, 1N4002, 1N4004, 1N4007) and a bunch of electrolytic capacitors, 1/4W resistors and some diodes, but not much more than that - everything I build will either need to be built from scratch (cabinet, etc.) or imported.
Of course I could go down to the shops and buy a 12V car-audio amp and stick that in, but where's the fun in that?
I guess I am looking around 10-15W. I mostly listen to jazz and acoustic stuff - not a head-banger - and not that loud, either. If they work out OK, I would make a pair for my wife's classroom, too. She has some awful plastic horrors that buzz and spit and generally sound like they have the mange.
Any advice gratefully received.
