Endothermal Systems

Endothermal Systems is a founder-led American hardware studio that develops physical products on fixed-price phases, from proof of concept to production, for clients who need engineering rather than a full agency.

Its work covers PCB design, embedded firmware, sensor arrays, enclosure and mechanism design, fluidics, 3D printing, CNC machining, data logging and design-for-manufacturing review. The studio’s debut product, CinderClock, is a programmable desktop clock with alarms, timers, calendar, reminders and an audio player, built to be open source, modular and repairable, with no app and no subscription.
