Small midi controller

s_midi

A small midi controller based on The rolls midi board I’ve designed. Working great although the keys are very crude, almost useless. However it’s a nice tool for debugging.

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.

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

midi Rolls – Almost

IMG_20170306_194737

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.

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.
