HeatCaller

Beta coming soon

Lap timing that calls the race for you.

HeatCaller runs race day from the timing PC — heats, transponders, laps, results — and announces it out loud while it does. Position changes, best laps, last-lap warnings, all over the PA without anyone holding a microphone.

What it does

One operator, one PC, a whole race day.

01 — Announcing

It calls the race

Start countdowns, position changes, lap counts, best-lap callouts and the last-lap warning, spoken through whatever speakers the track already has. The voice runs on the timing PC, so it keeps talking when the Wi-Fi doesn't.

02 — Heats

Heats and mains, sorted

Build the heat sheet from the entry list, seed by previous round, and roll through qualifiers into mains. HeatCaller tracks who is up, who is on deck, and calls drivers to the rostrum before their heat.

03 — Timing

Real transponder timing

Reads the loop directly over USB, so laps are decoder-accurate rather than thumb-on-a-stopwatch. Transponder IDs stay attached to drivers between race days — register once, not every Saturday.

04 — Results

Results worth posting

Per-round sheets with best lap and best three consecutive, ready to print for the pit wall or export as CSV for the club page. Nothing to retype on Sunday night.

Hardware

Built against the decoders club tracks actually own.

HeatCaller talks to EasyLap and I-Lap systems over USB. Plug the decoder into the timing PC, pick the port, and it starts reading passes — no bridge software, no subscription, no account.

It was written for a working Mini-Z track and runs there every race day, which is the only test that counts.

Beta is coming.

HeatCaller runs at one track today. The beta goes out once it can survive a full race day on somebody else's hardware — different decoder, different PC, different Saturday.

If you run a club track and want to be in that first group, say so and tell me which decoder you're on.
