Rumor of Smoke

I put online a website acting as an archive for the project that have been exposed in this blog. If people could be interested, it is here :

Wintermute V2

Long time I haven’t post something in here.

a new version of the wintermute is born. This one has a an aditional BandPass filter mode and bottom and top plates which make the thing looks sexier. The battery holder and internal speaker have been removed. I wasn’t fan of the poor frequency response of the speaker, and as the battery holder was only on the board to support the speaker, it moved out as well.


the kit is at 35euros, and contains the PCB and the bottom and front panels.

more infos : .

here’s a video from Canada showing the previous version and its sounds.

midi Rolls – Almost


The joy of ordering parts from the internet is that you need to wait for them to arrive. However, I managed to solder some parts and get the thing working. Everything fits perfectly into the box.

I think It’ll be an easy and quick job to finish that thing.

big brother

It was about time, I finally sank and opened a page at Big Brother, seems to be the necessary step to give a bit of visibility to the next projects. If you’re into that sort of things, do your facebooky stuff with the page :

Rolls Midi Rework

I spent quite a long time to see if the coordinates of the various elements were right as I didn’t have the orignal datas. But now it is time to see if there’s no poopoo. The all thing will be driven by the cheap-ass STM32f030K6 (less than 1 euros).

At that price, sorry Atmel, but I think I’ll switch for it instead of the atmega 328. There’re drawbacks (no DIP package and 3V3 which may need to be elevated to 5V with additional logic for some applications). Nonetheless, it remains an interesting alternative, for a cheaper price with better performances (although it doesn’t really make a change in here)

I managed to put input to all the vacant pins to allow the board to be used for other MIDI purposes. Mainly to not let the reaming boards unbuilt.


I also finally updated my old Kicad (2013) version. The new features are really  appreciable. The search function in EEschema is better and quicker. The 3D view is largely better as well. I did have many complains to make in the first place though.

Wintermute == Success;

The wintermute project was quite a success, all the remaing boards have been sold. And the resulting builts are all fonctional. I mus also make some shameless add for Elecrow PCB manufacturing. That was the second time I ordered things form them and everything went smoothly.

There were some stuff I didn’t really like on the board, the lofi speaker has a very poor bandwith for such application, and the battery holder took to much space. Both costed a lot and wasted boardspace.

I decided to take them off and add a lofi PT2399 delay instead, and this time with the glorious SMD parts (0805). For sure it’s less diy-friendly but SMD isn’t that hard, come one…


I’ve no ideas for the price yet and this time only the board will be available let’s first see if there’re interest in it. If you’d like one, send me an email (in the about section). Depending on that, I may launch a run.

And it is very strange to meet a American for New Mexico waiting for the train in my town, I felt like in a K. Dick book, did it really happen ?

Before the end (of the year)

here are three movies that could save you last hour of 2016. All are in black and white and are more or less trippy on their own rights. They are quite obscure and weird which make them even better.

Tetsuo (1989)



The story of a man who attracs all things metal because of a previous action. The plot isn’t more developped that than but the rest is something of strange beauty. There’s some quite disturbing images and the black and white makes it even more sureal. The film is full of ideas and strange things. It strangely reminded me of some early Godflesh albums, someting darker, intense and without any kind of concessions.

A Field In England (2013)



A bit less dark but not less psychedelic. Deserters of the english civil war find themself at the mercy of somekind of shaman and magic mushrooms. A man who run like a dog in a leash isn’t something that you’re accustomed to see and may leave you a bit chocked. Plus, the cinematography and images and wonderful with some very clever tricks.

Hard to be god (2014)


Maybe the more cryptic of the three. It is in Russian, it last 3hours, and in black and white. For most pepole only one of those reasons suffice to leave the room. It’s hard to follow and can make you feel a bit nauseous as the entire film is set in rain, mudd and shit. Add to that, a army of morrons that the protagonist must live with to save the little he has to save. However, I don’t know why, I watched it maybe because of the beautiful work produced, the imagery and the picture made of a decaying world which doesn’t want to evolve.
