I am an electronics engineer based in India, working in chip design. This site collects the other half of that work — the projects that do not make it into a datasheet but have been quietly useful nonetheless.
Most of what appears here began as a solution to a minor everyday problem. A sensor that needed logging. A signal that needed conditioning. A process that called for a small amount of automation. Commercial off-the-shelf devices exist for many of these things, but they tend not to last. A custom-built device, sized exactly to the task and built with parts you understand, tends to outlive whatever it replaced — sometimes by years.
A few of the things here I have built for others as well. In an era of disposable electronics, there is something worth documenting about small devices that simply keep working.
Beyond the projects themselves, the site covers the surrounding territory: setting up toolchains, working with EDA software, notes on specific chips and components encountered along the way. The intention is for each page to be useful on its own — something you can find from a search and read without needing the rest of the site as context.
What this is not: a personal blog. There is nothing here about my employer, the projects I work on professionally, or opinions on anything outside electronics and the software that supports it.
