It has been about a week that the sign was in the shop, it was successful in getting the customers attention however there have been a few downsides: 

• It is heavy and bulky due to the huge battery pack and perboard 
• Sometimes it can be a bit finicky, when ever it gets slightly bumped or the wires are touched, the pattern jumps a little bit 
• drains through power quickly 

My next plan for this project will be to buy an addressable led or even an RGB led strip and program it with an atmega328p. It has been fun building this whole sign from scratch but the sign is unreliable and doesn't last for long. Hopefully with being able to use a microcontroller and an led strip I will be able to save on power and make everything more stable and less finicky.
