Openlog is working fine when powered through the USB-connected FTDI Friend powering the Ardweeny and the Openlog. When I switch to 4AA NiMH batteries, it flashes the green light intermittently, and I have tons of small files when I open the card up. The batteries are charged up and are now out-putting 5.19V, which should be good to power the Atmega328 directly through the +5V pin with no voltage regulator, I think, and should definitely power the Openlog. I tried placing a few caps across the power supply terminals right before the Ardweeny and the Openlog, but to no avail. It happens with both a simple program I've been running of my own, and with the basic test file, at both 38400 and 9600 baud rates. Unfortunately, I don't have another Arduino to test with right now. Any other ideas to try?
