Making on Thomas Schwery

Photogrammetry and custom bow grip

Since I had some time this week, I decided to try to improve my bow grip using a 3D printer and the already customized bow grip that we worked on at the club some months ago.

The first steps were trial and error, by applying some 2 components paste on the grip, shoot some arrows, check that the hand was positioned correctly, add some paste, repeat until the hand was positioned correctly and comfortable.

KiCad compilation through Docker

While trying to compile KiCad from the latest sources, I had problems installing the large number of required dependencies with the correct versions on my two computers.

I already know of a tool that allows building a system image that is in a known state and can be executed independently of the host system : Docker.

In this article, I will summarize the different steps I took to compile KiCad from the sources into an AppImage that can then be copied onto the different systems that I use for my keyboard project.

Anlyea Quadcopter - Design phase

I started working on a custom Quadcopter for fun. I started from the Crossfire by MickeyB from which I redesigned large portions to better fit my needs.

Original Crossfire 2

I wanted a somewhat smaller design so that it fits inside a Rako box for transport. I started using the original arms but then, the original center piece was too large for the Quad to fit inside the 600mm x 400mm x 120mm Rako box I had on hand. As the difference was not that large, I decided to design a new replacement part using OpenSCAD because, hey, why not ?
