Yes. I did a V-I curve of the wall wart and it was fine. I inspected the ripple under load with my scope too. I also had it hooked to a TTI bench PSU at 5.000v

Yes. I did a V-I curve of the wall wart and it was fine. I inspected the ripple under load with my scope too. I also had it hooked to a TTI bench PSU at 5.000v and it still had problems (I have a large selection of proper test gear at my disposal).
They didn't like those facts.
- AlyssaRowan 12y agoThen you've got a dud. Lots of the first rev in particular had a few problems like this. That's ample evidence to exchange it for a new one. The later revs, particularly the B+, seem much more reliable (although occasional duds definitely do still happen).
- custardcream 12y agoWell you're probably right but after that face full, it went in the bin as i don't have the inclination to see if my time will be wasted again.
