With the primary intent of losing weight and making my cart more mobile and easier to manage, I built a new vertical cart frame with 8020. I also built a new 1RU DC system with 8 individually switched outputs powered by either AC or a 20Ah LiFePO4 pelican battery. I don't have final weights, but this cart is over 40lbs lighter than my previous cart based on a magliner vertical junior.
After having my monitors broken in the past, I moved the bnc inputs and outputs along with 2 audio in/outs to the base of the cart by the wheels so the cables laying on the ground and a bit protected and don't create a trip hazard. Also built a new script holder with a ram mount adjustable arm.
