It is the custom of Overall to have Christmas party for its employees every Christmas in the office, with different workshops. We made for one workshop LED-illuminated badges or reflectors that the workers could assembly themselves. Two types of badges were made, one with the Overall logo and the other with their mascot.
In terms of the simplicity, for easier assembly, of the electrical circuit, RGB LEDs were chosen, which require only 3V current and their own internal circuit changes the LED colors over time. In addition, it was possible to choose the LED shades you like. The scheme was kept simple with a battery, lights and a switch that disconnects the mains.
Based on the shape, different layers were chosen for the printed circuit board, and PCB production techniques were used to bring out various details. In addition, a gold finish was selected, i.e. the signs had a golden accent in the logo.
