Reviving small electronics by opening them up and forcing the battery back to charge.

The details of my latest short project, where I design and 3D-print the case and create a PCB on a protoboard for a two-minute timer.

A few tips & tricks on how to use blender effectively to produce valid STL files for 3D‑printing that I learned while creating models for tools I want to give to my kids.

A bit of a meta entry where we build a tool to fetch OVH apache logs, analyze the blog's logs and filter them to get a more realistic user count.

It is now time to take this project to the next level: soldering 4 chips to a protoboard, adding an Arduino, a mixing circuit, putting it all into a box, and making music! Finally!.

At this point in the project, we have reliable communication with one SN76489 chip on the breadboard and some form of sound output. In this article, we'll make it play its first note, control it from a computer, and start improving its musicality.
