The journey.

1. Feb – Jul 2025

   First sparks

   The channel opens in February 2025. An early build post in July 2025 shows a message and chat UI made while learning UI/UX design for an ALX pathway assignment.

   Camp circuits

   After an embedded systems summer camp at INSA, the channel starts showing hardware: a blinking Arduino LED, then a robotic arm with servo and stepper motors. In October 2025 come two team builds from the camp, a drone flight controller that still needed work to fly and a face-recognition attendance system.

   Streaks and reboots

   A mission to push GitHub commits for at least 30 days starts in late October 2025, followed by a streak check-in. Laptop trouble comes next, a failed BIOS update and later a motherboard fault, with an "I am back" post in February 2026. By March the channel has started circuit design in KiCad.

   Signals and a portfolio

   After a quiet spell, the channel returns in June 2026 with a simple 4-bit op-amp DAC meant for a bigger project. Posts on controlling signals with code and spotting noise on a triangle wave follow. In August it shares V1.0 of a portfolio site that took two months, then heads back to schematic design for a hackathon.

   Hackathon season

   In September 2026 the channel greets new subscribers with an introduction to its embedded systems, IoT and electronics focus, and shows off a new logo. October brings Viva, a thesis-defense practice app built for the STARK hackathon, a rename to Henok's blogs, and a plan to refocus on electronics and embedded projects.
