Jerry @maxboysdad recently provided me with a device new to me - - a Buck Converter - - as a method of powering the Dreamcatcher.
Simply put, a buck converter is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). Specifically, the one I’m testing steps voltages from 6 to 26 vdc down to 5.25 vdc at a maximum of 3 amps. This current is plenty to run the Dreamcatcher, and the 5.25 vdc is also within the Dreamcatcher’s operational range which I believe goes up to 5.5 vdc.
What makes it most useful is you can use any dc voltage power cube to run the Dreamcatcher - - you don’t have to use a USB power cube which may be hard to find with the required voltage and current capability.
My Dreamcatcher is now running off a 12 vdc power cube drawing .3 amps. The output going into the Dreamcatcher is 5.35 vdc (a bit higher than it’s spec) drawing 1.1 amps.
Here’s an example from Newegg.com for $3 complete with a standard USB plug to connect to the Dreamcatcher. Ken
