Testing the Adafruit UPDI Friend by programming an ATtiny1614 and validating a simple blink setup.

Integrating the BME280 sensor into a weather station project, debugging a BMP280 mix-up, and verifying sensor identity via I2C device ID.

Testing the weather station PCB by verifying the OLED display, UART connection, and sensor modules, while uncovering an unexpected BMP280 sensor mix-up.

Finishing the weather station prototype PCB, testing the assembled board, discovering an OLED pinout mismatch, and investigating reverse voltage through the LDO regulator.

Assembling and testing a custom weather station PCB, including SMD reflow using a hotplate, lessons learned, and early-stage debugging.

A practical look at using the ATtiny1614 as a low-cost co-processor in embedded systems, and where it fits alongside newer alternatives.

Testing cheap hotplates for SMD soldering and experimenting with Sn42Bi58 low-temperature solder paste.

A practical walkthrough of building a simple compiler for a custom Digital Sequencer DSL, covering lexical analysis, syntax parsing, semantic validation, and bytecode generation for embedded systems.

Defining the core instruction set for a digital sequencer DSL, including SET command behaviour, execution model considerations, and mapping to a compiled bytecode representation.
