I had grand plans for my DC adapter. I was going to make a carving out of wood onto which I would attach metal plates that would connect with the Brick where the batteries should really connect, and then I could simply insert and remove the wooden carving and the metal plates would slip into place.
But that didn’t happen.
So now I’ve solved my battery problem for a while and I don’t have to worry about having Bluetooth or Wifi drain my batteries. Yay!
I have absolutely no idea if this is good for the Brick in the long run though, but the battery indicator is showing something that looks about right, and it is still running after a few hours, so I’m assuming it is ok.
