My heart belongs to Bugbrand - ECG as CV source (video)

Author My heart belongs to Bugbrand - ECG as CV source (video)

I thought my modular lacked an ECG module to connect my heart as a CV source. I ordered a kit, which arrived today. Here's a first test:



All CV comes from my heart, including the sequencer clock. I use the heart signal both as a raw sound (very low-freq), and as CV to control pitch, FM mod, an LPG and some waveshaping on various oscillators.

Just a little test. Might become a performance piece in the future...

That is the coolest thing ever!

It's peanut butter jelly time! nanners nanners
Mind blown here...
I want to see the module palle!

This would make for the most interesting or porn videos ever. The audio would also synch automatically to picture. Score!

what ECG device are you using? i have often though about such a module. great sounds too.

A Ramsey EGC1C kit. I just finished building it.

that's really interesting. the signals are patched back into the heart by the way, as heart rate is heavily influenced by music.
otoskope
Exactly. That's part of the deal. But I wonder if it will result in an infinite accellerando, ending in a dead musician...? Dead Banana

I hope not.

And Kent, where were you planning to put your electrodes? twisted No, I don't want to know...

This is awesome!

Now just add Emotiv neuroheadset to also use your brainwaves as modulation sources and you don't have to touch it at all :-)

I have the brainROM for Piston Honda done by paperkettle which was done using Emotiv but haven't tried it yet - more info here if you're curious:

A couple of years ago I collected data from real, medically motivated measurements on myself, including a stroboscope-triggered EEG and a 24h ECG. I haven't had the time to write software to read those files yet, though, but they're there to be used some day. I also have long data series from my son's diabetes measurements.

Thanks for the telling me about the Emotiv! I think I've heard about it once, but then forgot. Will check out!

Now if you're able to sleep with sensors on you could patch before bedtime, leave it to record overnight and then listen in the morning! It's music that writes itself :-)

Thread Necromancy! I've been trying to google this without success - what is the Ramsey EGC1C kit?

Sorry, I misspelled it - its of course ECG1C:

I bought it from UK here:

I haven't done anything since last post because of extensive travelling. But I want to investigate the co-grounding of me and the synth through the audio jack before continuing. As I see it, there is a risk of currents flowing there when handling the modular, through touching panels, jacks etc with my hands, and I may need to limit those for safety reasons.

Indeed, indeed.

In *theory* based on my I AM NOT A DOCTOR OR AN ENGINEER OF MEDICAL DEVICES understanding, a proper one of these things is totally isolated from the electrical ground, but I have no idea if this kit meets those kinds of specifications.

I've been trying to get a WildDivine system (PulseOx and Galvanic Skin Response) working over in PureData - with very little luck, unfortunately. There are some fantastic tools to do it, but compiling them is tricky.
