Hello,
I did not have a cap on the output initally, but after it didn't work I wondered about that so I added a 10v 1000 microfarad cap that I had on hand. I assumed overkill would not be a problem in this application?
In answer to the other kind folks that replied. Before going up to 3.47V I tried 3.05 or something close to that then increased it a little after it didn't work. As for sanity checking, yes I checked the cam thinking perhaps I fried something but no, it still works fine on battery power. I wish I had the actual power supply it's meant to work with so I could see exactly what it's output is and see if it actually works with my camera.
The next thing I want to try it to disassemle the cam a bit and check the continuity of the connector and or perhaps try connecting my power supply directly to the battery contacts.
Thanks for your thoughts and ideas!
Have a great day!
