It's fine, no harm done and better to find out the DasMikro is a bit dodgy now than at an event or something...

I would definitely prefer a fuse but I'm struggling to find something suitably small. I did wonder about using a PTC resettable fuse instead, as that can be wired in permanently which saves some weight. Not sure how normal a solution that is though.

Botfest is in my sights, hoping we'll have something ready by then if we can make it!
