OVH apache logs fetch and analysis
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.
MIDI to SN76489 to chip music, part 3: putting it all together
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!.
MIDI to SN76489 to chip music, part 2: from noise to music
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.
MIDI to SN76489 to chip music, part 1-B: diving into an amplifier circuit
The TI chip can output up to 10 mA, which begs for some amplification. A few components I had bought or salvaged a while ago were looking at me with begging eyes, so this provided a good excuse to indulge.
MIDI to SN76489 to chip music, part 1: setting things up
The first installment in a series were we build a MIDI instrument from a bunch of SN76489s. In this article, we concentrate on setting up communication with a an SN76489 and getting some sound out of it.
