So, guys, this June, PCBWay celebratde their 5th anniversary and they appreciate our accompany along them. In return, they've prepared plenty of gifts for PCBWayers like us. But, in this post we will take a look at a differnet part from this anniversary of PCBWay. They have sent me a package with some great PCB samples, a cool T-shirt with the "Trust me I'm a PCBWAyer text" and a cool badge. This is not just a simple pin badge to put on your T-shirt or maybe backpack. This is a badge made out of a PCB and even more, it has some blincking LEDs. Usually this blincking process is amde with some sort of integrated circuit that could charge and discharge a capacitor and by that flicker the LED. But in this case, the design sues some smart LEDs. These are SMD small LEDs that are able to blink by themself. Jsut apply power and the LED will create their blink pattern as you could see in this gif on the side. Quite cool right?
