Version 14 of my custom PKE Meters is a simple design intended for cosplay use. As such, it has a very minimal amount of protrusions and no moving parts, which makes it a lot more durable and able to be handed off to others while at conventions and events. A series of 6 LEDs light up along the sides and chase back and forth from green to red. Two green LEDs stay lit at the very top along with 2 red lights next to the power switch. A color changing LED illuminates the view screen. All of the lights run off of a 9volt battery that is accessed by opening the bottom panel on the back. I made a custom leather holster for it too.
