This Repo is a collection of project files to a series of KiCad 7 tutorial, Which will take you through the journey of learning KiCad from scratch to making your first Printed Circuit Board.

Designed and implemented a custom rotary engine compression measurement tool with custom PCB and ATTiny85 firmware; validated compression across 4+ engines and reduced diagnostic cost from $200+ to <$30.
Rotary compresion tool is an open-source printed circuit board by FadyFaheem, from the FadyFaheem/REKT-Mini repository on GitHub, published under the MIT licence. It is a 2-layer board of 66 × 45.7 mm with 9 parts on 9 nets, routed with 19 tracks and 0 vias.
It is built around the ATTINY85V-10PU. Its parts include 3 connectors and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Built an embedded sensor data acquisition system with custom firmware (ATTiny85) and Python data processing pipeline, implementing real-time sensor fusion and calibration algorithms that reduced measurement time by ~85% compared to manual methods across 4+ validation runs.

ivourshalldevour/bicycle_odometer
A repository to hold all the code written for the MSP430 microcontroller I used while building my energy harvesting powered bicycle odometer.
It measures 66 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
9 parts, built around the ATTINY85V-10PU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the FadyFaheem/REKT-Mini repository on GitHub, at the commit this page was made from: the board is rotary-compresion-tool/rotary-compresion-tool.kicad_pcb and its schematic rotary-compresion-tool/rotary-compresion-tool.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
