Transistor Regular, is a free digital display font with the hard-edged look of LED and calculator lettering. The caps are built from faceted segments and sharp diagonal cuts, so the font feels both electronic and slightly industrial rather than smooth or futuristic.
It suits poster headlines, arcade-inspired branding, album covers, title cards, and event graphics where a free font can bring that segmented machine rhythm into a few big words. Because the letters are so modular and angular, it also works well for monograms, short cover lines, and logo-style marks that need a crisp, synthetic pulse.
