Sync HeartBeat to KORG Volca
Checking the signals in Serial Plotter of Arduino IDE
Gaudi edited the main Heart beat Code, Spike Recoreder V1.1 to have an output LED HIGH on Pin 12, when a 80% gliding max threshold is reached.
Just connect the KORG Sync-In with the BYB cable to your shield and there you go, the TEMPO of the synthesizer is controlled by your heartbeat. Each beat will be followed by 2 steps on the KORG, which is typical to allow swing and other sub-step rythms.
Hacking the PulseOximeter
Can we just hack a cheap Finger Pulse oximeter, to send out the heartbeat as CV or SYNC to a synth? ordered a few from ebay below 10$ and opening them up.
Easy to open from the front with a sharp knife and CLICK
Be careful, that thin flatband wire keeps breaking of, but can be fixed if your soldering skills are ok
Looking at the circuit, ICs and other stuff on the board
In the lower part there is only the 2 x AAA batteries and a red LED
Measurement concept is simple. The LED shines through your finger
Soldered long wires on the LED and the photosensor to be able to only place those onto the finger
