9V DVD to 5V USB power converter
« on: March 10, 2014, 09:29:59 AM »
I am in process of trying out a converter for my own DVD battery to provide USB power for my Sound Devices USBPre-2.  Once I finish and check it out there will extra supplies and I will probably have enough parts to make a few if there was any interest.  I don't know about the cost yet that will depend on what I build it in.  I had tried a simple voltage regulator in the past that did not work and this is a completely different approach.  Since I use my DVD battery to power a few different pieces of gear I will make it hot swappable and have 9volt and USB output.  The prototype is not picture worthy since it will only be a down and dirty workable model.  I'm looking for it to provide 5volts at a minimum of 500mA (USB specs), it might end up providing more amperage ;D  But if there is interest I would chip away at a  test version.  I just thought since there are a lot of us with DVD batteries and maybe there are others like me that could use a USB source in addition to the 9 volt source.  The Tascam 60D thread brought the idea back into my memory.  Chime in if this might be something that you'd like, Kirk

This is a great idea for those of you running multi voltage gear.
I had one that ran my ua5 and jb3/mt at the same time off one battery.

You've piqued my interest.  Good luck on this project, Kirk.
