Sur les réseaux sociaux, blog et autres publications, on parle très souvent de nos réussites (moi le premier). Aujourd’hui, j’ai décidé de vous parler d’un de mes "échecs" (notez les guillemets) récents : le jour où j’ai compris que je ne faisais pas du bon code.

This project is a continuation of the version 1 of the Drawing Machine I built a year ago. The previous Drawing Machine I build was based on T-Bot design. It had some disadvantages like it was heavy, cantilever-like design which gave it a swinging action that used to distort the drawing, and it was slow. So I decided to make some improvements in version 2.
