Weekend hacks that made it past the bench.

I'm Abhishek Bagade. I work on ML platforms at NVIDIA and keep a small homelab running in Bengaluru. This is the index for the side projects I usually post on Instagram: GenAI experiments, 3D-printable things, electronics hacks, self-hosted services, and the notes that survive after something finally works.

Notes from the bench

Things I wanted working

Ambilight for a monitor, a public URL for a local service, a tiny plant ecosystem, a photo-to-CAD pipeline. Usually some practical itch.

Cheap, local, reproducible

Used parts when they make sense, Arduino/Raspberry Pi when enough, systemd when boring is better, and notes on what breaks in Indian network or hardware reality.

No polished case studies

The useful bits are the constraints: weird build flags, NAT pain, cheap hardware tradeoffs, large data that does not fit in pandas, and outputs you can actually use.

Active hacks

CoastGen

Photos to 3D-printable coaster files. The interesting part is not the preview; it is getting a clean file that can go to a slicer.

GenAI + CAD experiments

Text-to-CAD, image-to-CAD, and the gap between a nice demo image and geometry with scale, constraints, and useful exports.

Self-hosted infra

A Lenovo M900 Tiny, Proxmox, Coolify, Syncthing, Obsidian, and a preference for services I can inspect when they fail.

Previous experiments

The older blog has longer posts for people who want the implementation details. This page is the gateway from Instagram and search to the actual notes.
