What an agent can do with the bx-tacho corpus

dazchi/bx-tacho: Open DIY Beyblade X launcher RPM meter: ESP32-C3 with IR sensors and an OLED, Bluetooth (Battle Pass protocol), and a browser app for shot…

Look up how bx-tacho implements 3d-printing, beyblade, beyblade-x, with answers cited to file and line.
Reuse a worked example: the commit “Calibrate black and white launchers separately, bump to 2.0.0” (13 files · C).
Answer from bx-tacho's real C source instead of memory (Web and frontend platform).

Example questions

Where does bx-tacho handle “Calibrate black and white launchers separately, bump to 2.0.0”?
How does bx-tacho implement 3d-printing?
What does firmware do in bx-tacho?

Paste it into your AI agent. It clones the repo at the pinned commit and indexes it on your machine.

Search the GitHub repository dazchi/bx-tacho with XERJ (https://hub.xerj.org/corpus/dazchi--bx-tacho).
Run these in a shell, in order, and check each result before the next:
1. xerj --help  (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh
2. git clone https://github.com/dazchi/bx-tacho bx-tacho && git -C bx-tacho checkout bf8c09c377b99e3546137e4c7707c9c654ea889d
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./bx-tacho --url http://127.0.0.1:9200 --prefix bx-tacho --progress plain
5. xerj autoindex map --url http://127.0.0.1:9200
Then answer my question from the indexed files and cite the ax_path of every hit. Query syntax: https://xerj.org/llms.txt
