The Cisco Flip Video UltraHD is a very basic 720p video recording device. It has a screen, a few buttons, and USB and HDMI ports. Not very much going on. Record, play back, copy to computer. However, these devices were discontinued, so my friend and I bought two to share at $29 a piece. I was very keen on using them together for 3D video.
To prepare for this weekend’s 2nd annual Ottawa Pinball Expo, I was making sure all my camera gear’s batteries were charged. The Flip UltraHD takes 2 AA batteries, which is generally enough to allow you to completely fill the camera’s 1 hour internal memory.
I noticed that there was a rechargeable battery pack you could buy for the Flips. It charges when the camera is plugged in to a USB port. This battery pack is really just two AA NiMH rechargeable batteries wrapped together, with a little tab that pushes on a switch to tell the camera that the pack is installed, and not regular AAs. When I realized this, I figured I could modify the Flips to work with my own AA NiMHs, and charge when connected to my computer.
