Weekly review · 25 October 2026
October in the lab
19–25 October: K8 buggy, Kayak Frame, solar firmware and the MATRIX concept. Designs, real parts and the next trials.
02 / Kayak Frame · CESCO3D
Kayak Frame: a structure that reveals its construction
A scale kayak model for exploring ribs, stringers and joints through 3D printing.
03 / Monitor solar · ESP32-S3
First solar diagnostic firmware
A 1024 × 600 touchscreen, local Wi-Fi access and a status API provide the software foundation for solar measurements.
04 / Eurorack Parts · CESCO3D
From modular design to the first print
A parts library exploring Eurorack structures, with CAD models, fit coupons and a digital catalogue in preparation.
05 / CELESTE · Perform
Eight banks, six tracks and musical direction
The October Perform revision brings layered composition to CELESTE, with a bar map and reversible musical changes.
06 / CELESTE · Parallel Fabric
CELESTE: from a web patch to FPGA audio
Stereo Line-In, parallel effects and shared control across web, encoders and HDMI.
07 / CELESTE · Pocket / MiniDrumMachine
Eight voices and sixteen grooves on an FPGA
The standalone CELESTE branch becomes a compact drum machine with physical controls and HDMI visualization.
08 / RED808 V2 · P4 + Daisy
RED808 V2: two boards, one musical state
The new architecture puts the interface and sequencer on P4 and dedicates Daisy to audio, linked by USB-C.
09 / ToonJS
ToonJS: preparing 2.0 starts with contracts
The audit strengthens the tabular engine, data semantics and real package installation.
10 / RayDrone
RayDrone: a studio interface over a reproducible core
The granular instrument gains clearer visual hierarchy, progressive controls and a documented build and regression process.
11 / ESP32 · Endoscope Viewer
A USB camera on a seven-inch ESP32 screen
The first viewer uses a Windows bridge to carry endoscope-camera video to the touchscreen.
Plugins · Windows + macOS · Tang Control
CELESTE Parallel
One source. Many textures.
Native stereo effect for Windows and Mac, with optional Tang Control: 44 CELESTE FPGA parameters automated from your DAW.

Live demo · ON·OFF Showcase 2026
From the lab to the stage at Sa Caleta
We presented our journey from analog to digital synthesis live and spoke with FITEL Televisió about the process, the instruments and the technology behind the sound.
The third ON·OFF edition turned Sa Caleta in Lloret de Mar into a space for electronic music and open culture. On August 1, it brought together 16 hours of programming, three stages, a market, gastro-bar, kids area, showcases and interviews: the ideal setting to take a prototype out of the studio, play it for an audience and explain how it is built.
