For a brilliant way to show off your name in lights, check out this luminescent nametag from Electronics corner. It features LEDs arranged on a 24×5 LED array, which can be powered constantly, or enabled with the press of a button.
This name tag can be ordered as a kit, or assembled with LEDs attached per your request. It comes with a brooch pin to allow it to attach to a backpack or clothing, and runs on a single 3V coin cell battery.
Interestingly, Electronics Corner notes that this board was from a failed project, meant to be controlled by an ATtiny–thus the blank “IC1” on the PCB. In its current iteration, it’s a neat little badge, and a good way to reuse a PCB that would otherwise go in the junk drawer, and/or in the trash!
If this little LED matrix isn’t quite your style, you could also check out the LED Sewing Kit featured here, by none other than Becky Stern!
