whybit.

think it. build it. vibe it.

tiny electronics for curious makers — out of bengaluru, india.

what's this?

the source of whybit.in — three static html pages with Tailwind (no build step, no framework fatigue). open it, read it, remix it.

the kits (coming soon)

• Lun-E RC — palm-sized tracked rover on a custom esp32-c3 board: n20 gear motors, printed chain tracks, esp-now radio and animated oled eyes.

the full build — hardware, wiring, firmware and print files — is documented at whybit.in/lun-e. the firmware itself lives at whybitlabs/T-01-The-Explorer (the repo still uses the T-01 name).

layout

index.html          →  whybit.in/
lun-e/index.html    →  whybit.in/lun-e     (lun-e rc — the current build)
lun-e/pcb/          →  whybit.in/lun-e/pcb  (the board: specs, bom, pinout, board files)
lun-e/evolution/    →  whybit.in/lun-e/evolution  (every version, v1 → now)
connect/            →  whybit.in/connect   (connect — the controller for lun-e)
about/index.html    →  whybit.in/about
contact/index.html  →  whybit.in/contact
images/             →  local media (images/lun-e-rc/, images/connect/ = renders)
models/             →  3d models (lun-e-rc.glb / connect.glb viewers, lun-e-explode.glb / connect-explode.glb home scroll sections, lun-e.glb v1)
downloads/lun-e-rc/ →  gerbers, board step, bom, printable stls
downloads/connect/  →  printable stls for the controller
styles.css          →  everything tailwind can't do elegantly
script.js           →  theme toggle, starfield, cursor glow, scroll blur
hero-explode.js     →  home page scroll sections: lun-e (hero) and connect spin and come apart as you scroll.
                       one config per model in CONFIGS; a section opts in with data-hero="lune" / "connect"

to add a version to the evolution page: copy one .evo-stop link in the rail and one chapter <section> in lun-e/evolution/index.html.

each page is standalone. the <head> boilerplate and the nav/footer chrome are duplicated across the three files on purpose — that's the tax for having no build step. edit one, edit all three.

# any static server works — serve from the repo root so /about/ resolves
python3 -m http.server 8080
# then open http://localhost:8080

site by absurd industries.

pre-orders

the home page has a free-reservation form (#preorder, preorder.js). it posts to a tiny worker (worker/index.js) that stores reservations in cloudflare d1. no payment is taken.

the site deploys and works without the database — the form just says "reservations open soon". to switch reservations on, once:

npx wrangler d1 create whybit-preorders
# paste the database_id it prints into wrangler.jsonc and un-comment the d1_databases block
npx wrangler d1 execute whybit-preorders --remote --file=worker/schema.sql
npx wrangler secret put ADMIN_KEY        # any long random string

then push. to download every reservation as a spreadsheet:

curl -H "Authorization: Bearer <ADMIN_KEY>" https://whybit.in/api/preorder/export -o preorders.csv

first batch size (20) and the kit list live at the top of worker/index.js. the first 20 units are reserved; anyone after that is saved as waitlist.
