Whats the minimum hard hardware I'd need (or something I could buy since I've not very good at kit making) for putting an infrared blaster on a raspberry pi.  

I run an old yamaha amp in a cupboard with a rasppi for volumio for input (plus fm).  I'd like to be able to control the volume, input and or on speakers via the pi.

I can probably nut out the software side and any coding I'd need, but couldn't figure out what hardware I'd need.  Preferably I'd like the IR transmitter on a short cable - although it's possible it will reflect off the white cabinet doors.

I do have a usbuirt I'm not really using (usb connected multi receiver and transmitter) that I guess would have linux drivers.

I also I think, have an old hauppauge ir blaster ina box somewhere (2.5mm plug I believe).

You'll probably have to go with the usbuirt if you are allergic to kit building. There is this which could be heavily miniaturised for tidiness sake though if you are up for the fun of building.

Are you outputting an analogue signal from the raspberry? Isn't it better to control your amp's volume?

I asked about a way to control air conditioners not long ago, people linked to interesting DIY projects which could be applicable.

That did look pretty simple.  The main con of the usbuirt is the size of the cable....and the fact it is plugged in to an htpc....but I don't tend to use it often.

Have a look at this: http://www.mysensors.org/build/ir

EDIT: Sorry, I thought it was for a Pi, but is arduino based. Might help either way though.

Yeah would you be able to strip that plug off and use it?   And the only other question is how would you know what frequency the receiver would accept.

Google it... there's instructables that tell you exactly what you need and how to do it.
