A Sneak Peak into Pipo modules video upload by Pipo Interfaces

Press release follows:
Pipo Interfaces brings a new versatile toolkit for creative sensing and audiovisual interactions in real-time.
Developed by creative technologist Rupert Renevier, Pipo is a range of electronics modules that connect sensors to computers, and are meant to simplify creative interactivity between people, real-world objects, and digital creation.
Whether you're performing, designing experimental MIDI instruments, or interested in making installations, Pipo builds the foundations of an accessible and adaptable open source toolkit.
When digital experiences become sensible and tangible, they allow for greater engagement and connection. The idea of using sensors for audiovisual applications and arts is far from being new, but still requires building custom solutions on Arduino or Raspberry Pi, which tends to be complex, time-consuming, and therefore not easily accessible to most.
Pipo wants to unlock the creative potential of real-time sensing, and lower the technical barrier to it, by proposing tools that connect the physical world to the digital in a straightforward fashion.
The Pipo recipe is simple: small affordable modules, wireless capabilities, and an intuitive yet powerful user interface. All Pipo modules can be used alone or in combination, fixed, worn on the body, embedded in objects, etc... All Pipo modules have mounting holes to augment all kind of projects and casing will be made available.
The first 3 modules of the family are Pipo Motion, Pipo Range and Pipo Analog.
Pipo Motion is dedicated to sensing movement: orientation, acceleration and magnetic field, thanks to an advanced 9 axis IMU (Inertial Measurement Unit). It allows for relative and absolute orientation.
Pipo Range is an accurate distance sensing unit which can be used to detect hands, obstacles, objects, or people (up to 3m). It can be used the same way as a theremin, or as a people proximity sensor for eg.
Finally, Pipo Analog, a versatile Input/Output device. On one side it has 8 capacitive touch inputs to create original touch buttons (for eg: with wires, metallic tape, vegetables, conductive paint, etc...)
On the other side it has multiple analog voltage inputs/outputs (up to 8). With these you can acquire and use any external buttons, specialized analog sensors modules, knobs or control servo motors, drivers, etc...
Beyond these three first sensing modules, Pipo Interfaces carries a vision for a whole creative ecosystem for many more input and also output modules. It has a strong anchor towards open source development and wants to create a strong user community connection.
Pipo modules can all send standard MIDI and/or OSC data wirelessly for maximum compatibility.
The connectivity is made through WiFi, Bluetooth Low Energy, or USB and every module has an onboard battery charger, so that whatever idea you have, you can test it quickly and have it communicate to your audiovisual software in a matter of seconds (no matter your operating system).
All the settings can be tuned in the field through a web interface hosted on every module. No need for an app or software, just open any web browser on your mobile. This interface allows you to set various settings like sensing parameters, ranges, and to adapt the incoming and outgoing data streams to your needs, quickly and easily.
You can for example eg fine tune the midi output, choose a note scale, channel, etc...
On a technical level, the project is developed with PlatformIO and the Arduino framework to make it easy for people to hack, modify, upgrade their pipos, or build their own custom Pipos. The software is open source, and the project runs on the Esp32-s3, one of the most versatile and powerful IoT chips around.
Pipo will launch as a pre-order campaign to fund the first production run. If you like Pipo, you can support it by entering your email address on the campaign page, it means a lot ! By doing so, you will also be notified of the launch date, so that you can be among the first people to get yours.
The launch date is pending on gathering a critical mass of people who want to see the project going live, so subscribing helps the project move forward.
All this happens on CrowdSupply, a platform dedicated to launching open source projects:
"Introducing an FM Drum circuit that fuses analog punch with metallic tones of FM synthesis. This DIY kit offers a wide range of sounds for your patches, from kicks to toms, metallic clangs and more – a great addition of versatile, rhythmic elements to your system!
We – Erica Synths and Moritz Klein – have developed a series of educational DIY kits under the brand name mki x es.EDU with one specific goal in mind: to teach people with little-to-no prior experience how to design analog synthesizer circuits from scratch. What you’ll find in the box is not simply meant to be soldered together and then disappear in your rack. Instead, we want to take you through the circuit design process step by step, explaining every choice we’ve made and how it impacts the finished module.
NB! All kits in these series are simple and come with extensive user manuals which can be downloaded separately, therefore we will not provide customer support in case your DIY build fails to function or similar."
Designing an FM Drum circuit from scratch (kick, tom, bell & cymbal)
"While trying to fix a broken TR-909, I came up with a DIY analog FM Drum circuit that combines the punchy character of the 909 with the metallic textures of FM synthesis. It comes with four different modes:
• 909-style kick/tom • Metallic bell/gong • Ring mod cymbal • FM cymbal
The FM Drum is the final drum voice in my DIY drum machine series (for now). If you want to build along, here's the bill of materials:"
"The Theremon+ is the successor to the kit-built Theremon by Groovesizer. While the original was limited to a single voice, the Theremon+ adds a second wavetable-based voice with an arpeggiator, and a drum section with various styles and 4 kits. The original was intended exclusively for the DIY market, but the plan is to sell the Theremon+ fully built. We hope to offer the Theremon+ at the same price point as the original (around US$130) - would you back it on Kickstarter?

"Ilse the Eurorack synth voice in one DIY module is making warm but harsh Berlin Techno / Surgeon style stabs.
Ilse is an elegantly minimal, yet fully functional synthesizer voice in a compact 10 HP Eurorack module. The only thing you need to let it meow is a CV source to trigger its 1V/Oct frequency input (or a MIDI to CV converter and a MIDI sequencer) . Because it has a low part count it is ideal for Eurorack beginners or entry-level DIY projects.
Ilse is named after a cat, living in the legendary “Villa” in Weimar, Germany. The “Villa” was a place where a community lived and came together. Many underground concerts and parties took place here before the house got sold, renovated, and the mayor moved in. We created the graphics on the aluminum face-plate in her memory. Ilse (the synth) makes great acid sounds, so it was only logical to illustrate a cat tripping. Turn the knobs to make her look around or roll her eyes.
Ilse is designed to be affordable, easy to build, yet flexible, and feature rich. It is a synthesizer voice for your Eurorack, but can even be driven without a rack using two 9V batteries (not included).
Ilse is fully open source (KiCad schematic and layout is available in a git repository) and inspired by Syntherjack’s single-chip synthesizer Totoro. Check out his website with nice explanations, e.g. on the filter (we use the same filter on Ilse). We extended the design for external voltage control on filter, oscillators and LFO. Unlike Totoro, Ilse is designed around a unique oscillator design, which integrates the exponential conversion directly into the oscillator core. This results in an efficient circuitry saving you build time, parts and costs.
PCB and face-plate are manufactured in the EU. Kitting was done by our friends from Befaco in Barcelona. Complete assembly manual can be found in our forum.

"Emute Lab Instruments is a new project, based at the University of Sussex, and coming out of the Experimental Music Technologies Lab research group.
Nick spoke to Dimitris about their first creation, the uSeq module, which bridges live coding and modular synthesis.
Rather than relying on laptops, uSeq uses a Raspberry Pi Pico to handle code expressions, translating them into control voltage (CV) and gate signals. Its design emphasizes accessibility, featuring an open-source platform that's DIY and budget-friendly.
The module has three CV and three gate outputs, coupled with a user-friendly coding language called *ModuLisp*. This setup allows you to manage multiple code patches and switch between them using onboard controls. Aiming to move beyond traditional code interaction, Dimitris is exploring vocal control methods, aligning with live coding's evolving narrative.
Available both as a DIY kit and a ready-made module"
"uSEQ is a eurorack module that brings livecoding into your modular system. Fundamentally, it’s an extremely flexible voltage generator and processor. It has a set of CV and pulse inputs and outputs, but instead of having a fixed set of controls and functions, you can choose how voltages are generated by livecoding them. This means that you can control uSEQ’s behaviour with the vast possibilities of creative coding, using a simplified programming language specialised for music. uSEQ is great for sequencing, waveform generation, and waveform processing. You can use it as a live performance tool, or configure it for specific functions.
To use uSEQ, hook up a computer via the USB port, load up the editor in your browser and start playing."
"Emute Lab Instruments is a new project, based at the University of Sussex, and coming out of the Experimental Music Technologies Lab research group.
Chris showed Nick their latest creation, Myriad a new multi-oscillator module.
This prototype featured nine oscillators organized into three banks with a hybrid analog-digital synthesis design, aimed at creating dynamic sounds. Chris explained the module's CV-controllable parameters, including pitch, spread, and octave control, designed for rich tonal diversity. An integrated wave-shaping and overdrive circuit added depth and distortion, with LEDs indicating the overdrive status.
It should be available soon through Signal Sounds and Thonk.

“In the year 2000, I was in college and obsessed with modular synths, but could barely afford to eat. I knew it was possible to build your own synth, but there wasn’t anyone, or anywhere to turn to for advice. In the past decade, much more information has been published online, and in 2013 I started down my path to DIY modular. Even with all of the information online, there still lacked a single, simple, comprehensive guide for those looking to build their own synthesizer. I want AI Synthesis to be that guide. Prior to building my own synth, I was a dreamer, after building my modular, I felt I had awoken. I want to help others do the same.”
"The T-16 is a custom semi-modular synth largely based on the analog circuits of the original ARP 2600 and ARP Odyssey, with additional modifications and modules.
Here's an initial sound exploration I recorded shortly after completing the project (with no added effects or processing).
Special thanks to Stefan Hambleton for helping with the build of this instrument!

"After two years of designing, soldering, assembling and a looot of troubleshooting, this mighty thing is finally finished (aside from some minor tweaks). I can’t really believe it yet, but it’s extremely exciting nonetheless. I’m not entirely sure what to do now that it’s done, but I suppose it is time to start making some cool sounds and writing new music? Anyway, stay posted for more T-16 content!
And big thanks to @hot.chip5 @alyndyh and @xavier.joseph.dlmh for the help and support along the way."
