Maker Madison Holmberg has constructed a traditional “Whats up, My Title Is” identify badge with a twist: It scrolls the textual content of the wearer’s selection over three LED matrices, underneath the management of a Microchip ATiny45.
“A makerspace I am part of has an evening that we’re open to the general public for individuals all in favour of becoming a member of,” Holmberg explains of the badge’s origins. “It is a enjoyable group occasion, and it is fantastic to see individuals get excited in regards to the makerspace too after we provide excursions of the services. Sometimes, members put on only a piece of tape with their identify written on it, however I wished to do one thing a bit additional and reveals off what you are able to do on the house.”
That “one thing a bit additional”: A wearable badge, impressed by iconic hand-written adhesive “Whats up, My Title Is,” which drives two or three LED matrices with scrolling textual content.
The badge is constructed from Maxim MAX7219 LED drivers linked to a Microchip ATtiny45 microcontroller working text-scrolling code initially developed by instructional improvement website Electronoobs.

“For many who’ve requested for information on my identify badge, please be affected person,” Holmberg asks of these desperate to strive constructing their very own. “I am just one individual, and I am very a lot new to all of this.
