Re: Hardware frustration - was Boomerang 3 midi sync

I took a look at the internal supply voltage of the Rang III and found it 
was about 12VDC (RMS, didn't check the ripple) when using the supplied 
adapter. So I think you would be safe with a 12VDC battery like those 
found in UPS units. These are available in many capacities and form 
factors and the prices are reasonable. They can be recharged but you'll 
need to find a proper charger for the Ah rating you use. Also you need to 
be sure the battery is not connected to audio ground or any other pedals 
since an isolated supply is important. Anyway, I'm pretty sure this would 
work and be reasonably cost effective.
