Blink if you love retro
7- and 14-segment fonts "DSEG"
Retro clock vibes ignite a nerd fight over lowercase and OLEDs
TLDR: DSEG is a free retro clock-style font with clever tricks for blinking and decimals. Comments split between playful lowercase letter experiments and a bigger fight: is old-school seven-segment still useful, or does modern OLED win? It matters because simple, reliable displays still power everyday dashboards.
Retro nostalgia just hit like a blinking colon. DSEG is a free digital number font that mimics old LED clock digits, with 7‑ and 14‑segment styles, tons of variants, and web‑friendly files. Devs are loving its quirky tricks: the colon has the same width as a space for easy “blink,” the period’s zero width keeps decimals tidy, “!” turns a digit off, and “~” blasts all segments on. But the comments turned into a typography showdown. One camp cheered the clean, retro look; another pitched chaos: make letters lowercase in seven‑segment. As mproud teased, lowercase E is easy, G looks like a 9, and you could even do a two‑story lowercase A. Suddenly “G = 9” became the new tabs‑vs‑spaces joke.
Then came the bigger question: is this practical today? kreelman loved the vibe but wondered if hardware for these displays is rare now, calling OLED screens the flashy newcomer while seven‑segment feels “so old fashioned.” Fans clapped back: for simple, monochrome info, fewer parts means fewer failures. The thread on HN pointed straight to the English page for DSEG, and license nerds cheered the permissive SIL Open Font License. Verdict: not just vibes — a hackable font powering clocks, calculators, and fresh retro memes.
