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
Embryonic Shifts
A large mechanical zoetrope for a STE(A)M installation on biology and identity — 72 sculpted objects in three stacked layers, frozen mid-rotation by a strobe that has to land in the same angular place every single revolution.
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.
Holonomic Odometry Testbed
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.
PixelFace
A volumetric persistence-of-vision display. Fourteen addressable LEDs on a pair of acrylic arms spinning at 1100 RPM, drawing a face in the air around a cylinder.
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.
TurtleSense
An environmental sensor mesh for a wild tortoise preservation programme in Bhawal Reserve Forest.
Flute Mic Clamps for the NUX B-6
3D printed clamps that mount a NUX B-6 Pro wireless saxophone mic onto bamboo and metal flutes. Five clamp sizes, ten TPU spacers, quick-swap between songs.
Writing up
Bangla Word Clock
A clock that tells time in Bangla words. With Ghorar Dim Studios.
Spinoscope / Praxinoscope
The other kinetic animation devices for Ghorar Dim Studios — the ones that aren’t the Embryonic Shifts zoetrope.
E-Braille
Tactile feedback Braille reader. Won the first Make-a-Thon in Bangladesh.
Argus Helmet
Smart helmet hackathon entry at Maker’s Lab, hosted by Toru.
CCSE Makerspace
Built and ran the makerspace inside the CCSE lab at IUB.
Raspberry Pi Hadoop Cluster
A four-Pi Hadoop cluster, built for the CCSE lab.
