I bought a 1979 Soviet "Moskva" PP-215-8M portable typewriter. Its manual only exists in Russian, so I translated it to English.

Building a Self-Maintaining Second Brain

Building a Self-Maintaining Second Brain

How I set up an Obsidian vault that files itself using Karpathy's LLM-Wiki pattern and Claude Code. One evening of setup — a knowledge base that compounds rather than piles.

KiCad with Claude

KiCad with Claude

Start Date: 29/06/26  Â·  Last Edited: 29/06/26  Â·  Status: Finished

A practical workflow for hardware design with Claude Code — LCSC part numbers, manufacturing folder structure, design calcs, and issue tracking, packaged as a KiCad project template.

For my Rocket Clock project I need many face plates. I realised, I could stack them, but there's no convenient tool do so - so I built one.

Linear Regression Deep Dive

I recently utilised a linear regression machine learning algorithm at work. It was incredibly affective, and I wanted to get an intuative understanding of how it worked.

Needed a sign that said "Aurora" -- added cool RGB LEDs. All 3D printed.

Robot Dog Butler

My daughter really wants a dog, so we settled on a robot dog (called Cedric, named by my daughter). I thought it would be cool to make it useful, so we'll attached a steward platform to the top, and make it carry drinks.

Inductive Charger from Scratch

Inductive Charger from Scratch

Start Date: 26/02/26  Â·  Last Edited: 26/02/26  Â·  Status: Ongoing

A recent project of mine required some custom, non standard coil, inductive charging. I want to document my development of this custom wireless/inductive charger.

LED Streaming Display - Rocket Countdown

Start Date: 02/02/26  Â·  Last Edited: 03/04/26 Â·  Status: Ongoing

I really want to have an old school scrolling display in my room. I kinda want it to have the time, temperature outside, etc., but also show me when and who is the next rocket launch. So, this is my design of such a thing.

Making an Enclosure for 3D Printer

Making an Enclosure for 3D Printer

Start Date: 02/02/26  Â·  Last Edited: 20/03/26  Â·  Status: Ongoing

I recently bought a new 3D printer (retiring my old homemade one!). I wanted an enclosure to stop accidental touches (from 3 year old hands!) and also extract fumes from plastics like PETG. This is my build process, documented.

I'm reverse engineering a Snaptain AF15 drone, to be able to fly it from my laptop.

DIY One Wheel

DIY One Wheel

Start Date: 31/07/2022  Â·  Last Edited: 24/06/26  Â·  Status: Ongoing

A self balancing electric skateboard. Superseded by the Robot Dog Butler — which requires a custom BLDC driver with torque control that the VESC doesn't support, making a custom motor driver necessary anyway.
