Making Custom Eurorack Front Panels with a Laser Engraver


video upload by Extralife

"I finally got a new, larger eurorack case! But it's shallower than my old one, so I need to re-format some modules to fit. Time to make a custom faceplate with my new laser engraver.

I'm combining 3 of the Hexinverter NeinOhNein drum modules into one so I can stack the PCBs and make a module sandwich. This is a very ad-hoc and manual process, but the front panel can be designed on the computer for a more professional looking result.

I ended up using some satin black Rustoleum spraypaint on top of some matte white Krylon. The laser is absorbed by the black paint, ablating it, and reflected by the white, leaving it intact. You can then remove the paint residue using rubbing alcohol.

The laser settings were very forgiving, I think I ended up using about 20% power and 100mm/minute for most of the marking. I found it was helpful to slightly defocus the laser to cover a wider area during engraving and to not mark the black paint when moving around in 'finding' mode (5.5W at 1% will still etch black surfaces!).

DIY MIDI Patch Storage box for Yamaha Reface CS


video upload by Extralife

"I love the Yamaha Reface CS but its Achilles' heel is its inability to remember patches or presets. I created a device to solve this by storing the control change values and re-setting them over MIDI, using Arduino nano and a custom interface PCB.

ER-99 Online Web-Based Roland TR-909 Emulator by Extralife Instruments


video upload by Extralife

Update: video added above.

"Play the ER-99 free here! https://extralifeinstruments.com/er-99/

Celebrate electronic music history on 9/09 day with ER-99, a web-based instrument 🎛️ based on a famous Japanese drum machine from the 1980s. It was built to celebrate 9/09 day 2022 🎉!

All of the drums are synthesized using the WebAudio API. The hi-hats, crash, and ride cymbals are produced from sampled audio.

The complete source code is available on Github: https://github.com/matthewcieplak/er-99"

Original post:



This one is in via Extralife, maker of the Super Sixteen DIY Eurorack Sequencer, featured in additional posts here.

"This year, to celebrate 9/09 day, I've built a free, open-source analog drum synth you can play in your web browser. It's called ER-99, and you can play it here (works best on desktop devices!)

You can program patches and sequences on the web interface and save them as presets using the menu below the sequencer. (I have also added MIDI input for sync with external sequences).

You can also read the complete source code on Github. It's surprising how simple many of these sounds are to make!

The original Japanese drum machine that inspired this project is an analog sound design masterpiece, and you can read circuit analysis about its clever use of noise and bandpass filters over on Network 909. I've tried to use the same techniques in the digital domain but I'm sure I can tweak them to get even closer sounding: http://www.network-909.de/circuit.htm"

Big Button trigger sequencer MIDI upgrade


Extralife

"Get the firmware and schematics here: https://github.com/matthewcieplak/hex...

I modified the Look Mum No Computer big button sequencer that I built to sport MIDI input and thru, as well as a new "shift" button that adds some new sequencing features to the front panel, like mute, solo, bank/all and roll. Now I can use it as a MIDI-to-gate converter or program sequences on top of any existing rhythm.

It's a somewhat complex but not super hard mod that just requires a small daughterboard to isolate the midi input signal with a 6N138 optoisolator and support circuitry. The inside is a mess of wires but it's great to be able to sync it up with my other gear."

Making a Circuit Board Soldering Jig for the Super Sixteen


Extralife

"With a big job of PCB soldering ahead of me, I decided to make the task a little easier and more repeatable by building a jig to hold the various parts in place while they're being installed.

In the past I've done this by attaching and removing the front panel by its various threaded fasteners, which can be fiddly and time-consuming. This simple home-made jig allows quick and easy alignment of all the critical parts and will hopefully allow me to build up complete modules much faster."

Super Sixteen is Fully Funded!!


Extralife

"Thanks so much to everyone who made this possible! Incredibly excited to get started making modules.
https://www.kickstarter.com/projects/...

In a surprise last-minute push we managed to get nearly 100 new backers in 48 hours get over the kickstarter threshold at the very last minute. I'm as pleased as I am surprised at this result.

In this video I also show off a bonus feature, black PCB front panels! Send me a message on Kickstarter if you pledged and would like one of these instead of an aluminum panel with black text.

I also discuss kits and sourcing some harder-to-find components. I hope to make an announcement about parts kit availability soon - please let me know if you're interested as it will help me judge how many kits to stock."

Riffs on Modular?? 10 Modern Classic Synth Lines Done on Eurorack


Extralife

Super Sixteen → https://www.kickstarter.com/projects/...
I had so much fun recreating that Daft Punk track last time I decided to come back for a second helping. Ten more in fact! I picked a decade of delicious synth treats from my music collection and spent a day recreating them on my homemade eurorack system. We modular nerds have a (perhaps deserved) reputation for being the noodly and undisciplined nomads of the synth world, so I wanted to show another side of the instrument!

And to all my wooly and wired synth comrades out there patching in the blinking darkness, I salute you. Onward to higher planes of sound.

Here is the tracklist:
0:00 Disclosure - "When a Fire Starts to Burn"
1:01 Riton & Kah-Lo - "Fake ID"
1:57 Fatboy Slim - "Acid 8000"
3:17 Simian Mobile Disco - "Cruel Intentions"
4:02 Booka Shade - "Friend for a Night"
5:20 Justice - "Waters of Nazareth"
7:07 Kavinsky - "Nightcall"
8:06 Roisin Murphy - "Overpowered"
9:36 Soulwax - "Krack"
10:42 Todd Terje - "Ragysh"

Daft Punk "Da Funk" on modular synth & Bass Station II


Extralife

"The eurorack sequencer used in this video is now on Kickstarter! Click below for more info:
https://www.kickstarter.com/projects/...

After many years of listening and contemplating it, I finally decided to dive in recreate Daft Punk's classic acid house burner with my modular synth setup. Every sound you hear was created on the gear you see! The drums are hexinverter 909 modules (the sub bass comes from the kick), and some samples on the Squarp Rample (hi hats, drum break, horn stab). The first bassline is on the Novation Bass Station II using some external feedback looping for more growl. The classic 303 line is recreated using my open-source Super Sixteen sequencer, MFOS VCO as an oscillator, Yusynth Moog Ladder Filter, and a SansAmp Para Driver. Some EQ and buss compression was added to the recording.

Sorry that 25% of the video ended up being the top of my head! Still working on a proper overhead camera setup. Will fix that for the next jam."

Building Mutable Instruments Braids / Learning Hot Air Soldering


Published on Mar 11, 2020 Extralife

"I need to learn SMD soldering so I picked up a PCB and parts for the classic eurorack digital oscillator, mutable instruments' Braids by Emilie Gillet. This version has been superseded in some ways by Plaits but I quite like the look of this one regardless.

I tried out a couple different soldering techniques including classic tack-and-place with the iron and lead-free solder paste with a hot air station. The paste wasn't super easy but maybe leaded paste is better for DIY work. Along the way I fried a couple components and had to troubleshoot so I tried to give some insight into how I track that stuff down and fix it.

The module sounds great! I needed to upgrade my case power supply after this build but that's massively improved with a separate digital power rail.

You cab download KiCad EDA 5.0 for free here: http://kicad-pcb.org.
For a detailed look at how to multiplex a grid of LEDs, check out this tutorial (a shift register is used instead of an i/o expander).

Playlist:
1. Designing a Eurorack Sequencer - Pt. 1: Digital to Analog
In this new series I'll be designing, prototyping and building a sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we connect the arduino to our 12v power supply and add a digital-to-analog converter output so our sequencer can output proper 0-8v CV signals.
2. Designing a Eurorack Sequencer - Part 2: Seven Segment Displays
Continuing to design and prototype the Super Sixteen sequencer module for my eurorack sythesizer using the Arduino platform. In this episode, we wire up a seven segment display to show some visual feedback using another serial chip, the I/O expander. Then we take a crack at making our sequencer play a scale!
3. Designing a Eurorack Sequencer - Part 3: Enter the Matrix
Continuing with the Super Sixteen, we build the sequencer's namesake sixteen-button grid, explore matrix wiring and multiplexing in combination, and construct our first working prototype that actually plays a sequence!
4. Designing Eurorack Sequencer Part 4: Making a PCB with KiCad 5.0
In this episode we get into some proper electronics design with KiCad and develop a new layout for a printed circuit board. Then we get to do the fun part and fabricate it at home using a toner transfer and ferric chloride etching.
5. Designing a Eurorack Sequencer - Part 5: Assembly
In this episode we assemble the first PCB prototype of the Super Sixteen with our trusty soldering iron and a spool of mod wire. After a few fried chips and more than a few repairs, it's time to wire it up to our synth and try out some actual sequencing!
6. Designing a Eurorack Sequencer - Part 6: Front Panel and External Sync
Or, "How to Make a Eurorack Front Panel: The Cheap Way"
In this episode we upgrade our module with a faceplate, and add some advanced features like external sync, pitch calibration, and glide/portamento.
7. Designing a Eurorack Sequencer part 7 - New PCBs, Motion Recording, Beat Repeat
In this episode, we assemble, inspect, debug, and reprogram our new dual-PCB stackup for the Super Sixteen eurorack CV sequencer. Not everything goes according to plan!
8. Designing A Eurorack Sequencer Part 8: New panel, Patch memory, Performance effects
In this installment we fabricate a new front panel for the Super Sixteen using the toner transfer process, and then take a spin with some of the new advanced features it sports, like patch memory, scale selection, swing timing, and a gang of performance rhythm effects.

Korg Monotron CV Input Mod (Eurorack Control Voltage hack)


Published on Sep 21, 2019 Extralife

"Hello friends! I'm back in California and back in action. First off the hop is a travel kit project to convert CV (control voltage) signals to Monotron-compatible pitch/gate signals. If you have a Monotron (the cheapest analog synth on then market) you can use it to add a complete synth voice to your eurorack system!

The schematics and PCB layout for this project are up on my github page:
