Project Hanging Plotter
First Steps - Pinning an idea down and checking assumptions
The design process has to start with validating the basis for decisions
Post Print Iterations
3d printing allows quickly iterating on taking assembly issues and applying them to the design
ESP32 development in NixOS using VSCode
Setting up an esp32 development environment in nixos using vscode and ESP-IDF
Spinning a Stepper
Let's spin a stepper motor using ESP-IDF (FreeRTOS) on an ESP32!
Android development on NixOS
Here we go, time for PAIN
Connecting an ESP32 to android with bluetooth
Communicating between a Flutter app on Android and an ESP32 under ESP-IDF
Using an ESP32 as a logic analyzer
Diagnosing stepper timing issues with another esp32
Using an Arduino as a logic analyzer
Using an arduino uno as a logic analyzer
Driving steppers with the RMT module
Using Nix to write rust on the esp32
In the interest of repeatable builds we must create a nix derivation for a rust-esp32 toolchain
Using a smooth stepper driver on the esp32 in rust
Stepper drivers are used as a simpler interface to control stepper motors, here we use the esp-idf RMT peripheral to send step pulses
Translating an esp32+esp-idf bluetooth example to rust
A rusty heart beats away inside this thinking rock
