About

I am Elliot Marsh. I write firmware for sensors that live in the flat I actually sleep in. The work is ordinary: a CO2 node that does not drift, a switch that reports the gang I pressed, a fan controller that does not need a cloud account.

These pages are static on purpose. There is no comment form, no newsletter, and no analytics. If a note is wrong, the next note says so.

I am not a shop. Nothing here is a product listing, and I do not take sponsorships for boards I have not already bought with my own money.
