Hey guys! This is my first post here, but I've been following this site for some time and really like it. I wanted to share a project on which I've been working for a long time. It's called 'LightSeq' and it's a raspberry pi / arduino based system for live electronic music performance. Here is a general intro video: Vimeo and a documentation of performance: Youtube At the moment I'm finishing building version 2 prototype with added color sensitivity, synq in and out, CV out and few other features. I'm thinking to make them available for sale in the future and wold appreciate some input from you guys. Hope you enjoy and comment, and share. Cheers! hardware Instrument diy technique Performance

Welcome aboard @ctrlfreq!

This project is something else. I like the look of the main board, curious what all is going on there? Is it possible to use alternative light sources? IE, sit around in a train station and try to "capture" the passing lights from the train? Or does the source have to be quite close up? Possible to build some kind of app to have participants in the crowd interact with your rig somehow (Bluetooth, etc)?

The drum bit is interesting.

What parts of this are you working on currently? Thank you for sharing, curious to see/hear more updates.

Thanks for your comment @bogdan! The main board contains mostly a lot of potentiometers and buttons for controlling sound patches and the sequencer settings. In the new version everything will be in one box in order to make it more compact. You can use any light source because the sensors react to the changes in light, also playing with shadows is very interesting. In my previous project, which is a predecessor of this one I used bicycle lights, candles and other light sources (like here: Vimeo ). However for greater accuracy it's better to keep the light source close to the sensor, also any ambient light can interfere with them...

There are more examples on my vimeo profile: Vimeo . People keep asking me if I'm planning to make the light holders wireless, this would also open up a possibility to control it by multiple users, however at the moment I am not planning to do that (it would make it much more expensive), I think it's already nice to let people move the light as they are, this could work as an interactive installation. Also one important thing about it is NOT to have a computer screen so mobile app would go against it. I want to have a vintage / analog feel to it. Currently I'm implementing color detection, synq in & out and audio efx section (I have a filter and delay working, next will be bit reduction, fm/am/rm and some others).

@ctrlfreq it's quite interesting in itself that your idea, this creation, inspires ideas from others. I love to see these kinds of special instruments being thought about and created. It's a welcome change from the mundane 16-step drumbox. Keep us posted on dev pls!

@ctrlfreq that's interesting to know, some great ideas, ambitious! You just do this on the side for fun or performance or hoping to make it commercial / sell them? Or all of the above? Just curious...

@bogdan Thanks for your input! Indeed, it's very interesting to see how different people see different ideas and possibilities of this project. It's also open source, so more adventurous / advanced users will be able to add and improve features, which will be exciting to see. Also these kind of projectc keep popping up more and more often thanks to RPI and TEENSY and ARDUINO platforms. Answering your other question - It's my main live performance tool at the moment but I'm also considering making them commercially available / putting them on crowdfunding campaign, but it's a huuuugeeeee job and I'm working on my own. Anyways I'm glad you like it, I'm a huge fan of your music, it would be great to let you test one of these gizmos in the future...

@ctrlfreq respects for making it O/S. Post some vids of you performing with this when you get around to it. It'll be fun to watch your development / progress. Thank you for the kind words about my music. I'd welcome the opportunity to test this out one day!

@bogdan Here is the best documentation of a live set that I did with LightSeq so far: Youtube The sound quality is not the best (camera mic) and you can hear ppl talking, but it gives a good general idea. I will post updates here. By the way where are you based these days? UK?
