<description>Elixir Wizards is an interview-style podcast for anyone interested in functional programming and the Elixir Programming Language. Hosted by SmartLogic engineers and Elixirists Owen Bickford, Dan Ivovich, and Sundi Myint, this show features in-depth discussions with some of the brightest minds in the industry, discussing training and documentation in Phoenix LiveView, the evolution of programming languages, Erlang VM, and more.
In the current season, we&apos;re branching out from Elixir to compare notes with thought leaders and software engineers from programming languages like JavaScript, Ruby on Rails, Go, Scala, Java, and more. Each episode will take a deep dive into a topic from Machine Learning and AI, to ECS and game development, to education and community.

<description>Today on Elixir Wizards, Bryan Green shares how he transformed a vintage 1930s rotary phone into a fully functional cell phone using Elixir, Nerves, and a mix of hardware components.
Bryan shares the highs and lows of his project, from decoding rotary dial clicks to troubleshooting hardware issues with LED outputs. He explains why Nerves was the perfect fit for this project, offering SSH access, over-the-air updates, and remote debugging. You’ll also hear how Elixir’s concurrency model helped him manage hardware inputs and outputs efficiently using GenStateMachine and Genservers.
Elixir and Nerves really shine when modeling real-world systems. Bryan dives into how he used a finite state machine to track the phone’s states and handled inputs from the rotary dial and hook switch via GPIO.
For hardware enthusiasts, Bryan’s advice is to embrace this “golden age” of DIY electronics. Whether you&apos;re experienced with embedded systems or just curious on where to start, Bryan&apos;s VintageCell can inspire you to tinker with a hardware engineering project.
Key topics discussed in this episode:
Advantages of functional programming and immutability in Elixir
Building hardware projects using Adafruit components
Why Nerves was the best choice for the VintageCell project
Interpreting rotary dial clicks using GPIO and circuits.gpio
Troubleshooting hardware issues with LED diagnostics
Challenges in optimizing wiring and PCB design
Benefits of Nerves: SSH access, OTA updates, and remote debugging
Modeling real-world systems with Elixir and Nerves
Implementing a finite state machine with GenStateMachine
Managing input with Genservers for rotary dial and hook switch
Leveraging community resources like Discord, Elixir Slack, and forums
Practical advice for keeping hardware projects on track
Potential applications from SMS servers to home automation
