Hi Bob & all.

This is the Bluetooth board which Juergen has used in his critter.
There are numerous Bluetooth receiver boards around.
This one has a BUILT IN amplifier, of 3W+3W (some don't).
It is available on eBay for $2 a couple of bucks, inc. P&P.
The dimensions of the board are 40mm x 24mm.
It requires a 5-Volt power supply. 
Which could be derived from a 2-cell LiPo battery. 
Using a simple & cheap '7805' (or similar) 3-pin Voltage-regulator.



I am investigating an EVEN SMALLER option or two at present as well.
