## Status

Built and tested end to end on simulated sensors: `tools/sim.py` stands in for the GPS and the
radio, and CI runs every test, including the ones against PostGIS. 11 of the 17 stories in
[ROADMAP.md](ROADMAP.md) are done. Of the real hardware, only the web update has been tried so far:
a bundle uploaded to a reTerminal installed and the daemon came back.

Next, on the reTerminal:
CarChomp is a rewrite of carputer, which ran on a Raspberry Pi with a GPS module and an RTL-SDR, the
hardware [stakeholder.md](stakeholder.md) describes. The rewrite is built and tested end to end on
simulated sensors: `tools/sim.py` stands in for the GPS and the radio, and CI runs every test, including
the ones against PostGIS. 11 of the 17 stories in [ROADMAP.md](ROADMAP.md) are done. On its own
hardware so far, a web update ran on a reTerminal: a bundle uploaded there installed, and the daemon
came back.

The rewrite's own hardware runs come next, on the reTerminal:

- GPS fixes from a real receiver, and the clock set from them through chrony.
- APRS from an RTL-SDR dongle through Direwolf.
