As a master machinist and electronics expert, he was one of the originators of the blinky pendants that made their appearance in fandom in the 1970s, once LEDs and the 555 timer chip became ubiquitous. Tullio has since incorporated blinky circuitry in many devices, sold at conventions under the name Isher Enterprises, after A. E. van Vogt's Weapon Shops of Isher story. Alex Ellingsen, Renee Sieber, Amy Ranger and others have contributed their blood, sweat, and tears to the Isher Enterprises efforts.
Jim Fuerstenberg encountered Tullio and his blinkies at a mid-’70s convention, and immediately introduced him to Steve Johnson, who had also been making them in the DePaul University machine shop and electronics shop as a student. The connection between the three was instrumental in collecting the people who founded General Technics, and in the construction of a number of radio-controlled robots.
Tullio has been active in Critter Crunch (small scale BattleBot) competitions at Midwestern conventions, mentoring young participants and frequently winning these competitions with them.
He was formerly married to Amy Ranger.
