What I've built.
A working archive. Some of these have full pages; others are stubs while I write them up. Roughly chronological, organised by what kind of work it was.
Documented
WiFi Picchi
Community internet hotspots at slum tea stores in Dhaka. Five taka for three hours of WiFi, paid by token, hosted by the shop.

Built a four-mecanum-wheel robot to understand holonomic kinematics hands-on — how the math works, where wheels slip, and what it takes to correct for it in firmware.
BlackHorse HAB
Sent a Bangladeshi flag to 32.45 km on a helium balloon. Built the electronics, the antenna, and the payload. Recovered everything.
Fab Lab IUB
Helped win a World Bank grant to set up a digital fabrication lab at IUB. The lab is still running.
Fab Academy 2019 — Weekly Documentation
19 weeks of build logs — laser cutting, PCB design, CNC machining, molding, embedded programming, and more.
Fab Academy 2019 — Final Project
Nineteen weeks of digital fabrication at Fab Lab CEPT. Final project: PixelFace, a pixel-display mask.
Lumo / Elektra — vehicle CAN bus reader
Two-revision vehicle CAN bus reader built at TeroLabs — v1 a Raspberry Pi HAT for prototyping, v2 a standalone BLE device for in-car deployment.
