BEAM There, Done That

About BEAM There, Done That

BEAM There, Done That is a podcast about building real systems with Elixir, Erlang, and the BEAM. We’ve built it before — distributed systems, fault‑tolerant services, event pipelines, real‑time apps, production nightmares, and the supervision trees that saved them. Each episode dives into practical lessons from shipping software on the BEAM: architecture decisions, scaling challenges, operational failures, and the patterns that actually work. No hype. No theory without scars. Just hard‑won experience from engineers who’ve been there.

   Embedded Gleam for Everyone: D. Bettio & G. Cavalieri on Microcontrollers

   In 2017, Davide Bettio created AtomVM to run Erlang, Elixir and Gleam code on embedded devices with just a few kilobytes of memory. Fast forward to today, and Giacomo Cavalieri of the Gleam core team has built tooling that flashes a Gleam project onto a board with a single command. Two dollars, some sensors, and a weekend is all it takes to get started with embedded Erlang development. No more dealing with low-level C, complex drivers, or painful debugging. Gleam's delightful developer experience combined with AtomVM's BEAM bytecode support brings approachable IoT to the masses. In this episode, Davide and Giacomo share: How AtomVM squeezes the BEAM onto memory-constrained devices Why Gleam and AtomVM are a perfect match for hobbyists and students Davide's "scar story" of a buggy AtomVM-powered home thermostat leaving him debugging in the cold The trade-offs of the AtomVM standard library and how to extend it Writing Gleam bindings for AtomVM features via Erlang FFI Example projects to tackle as an embedded Gleam beginner What's possible with $2 boards, some sensors, and MQTT Recorded October 12, 2026.

Embedded Gleam for Everyone: D. Bettio & G. Cavalieri on Microcontrollers

Published 23 Oct 2026 · Transcript excerpt

[…] Jacob, let's start with Gleam. If someone's never written a line of it, What does it feel like to work in it and what does it do differently than other programming languages on the Beam? Well, hopefully it does feel good writing it if you've never done any Gleam before, at least if we've done a good job. The goal with Gleam is to feel familiar to developers, especially if you're coming from more mainstream languages, something like in the C style of languages, I don't know, maybe you've written JavaScript, maybe you've done some Java, And so looking at Gleam, it should look familiar. You can have a pretty good sense of what is going on, maybe besides some more fancier features. […]
