1. Successfully built a basic EEG/ECG electrode pair @hakkavelin — got heartbeat readouts showing on an oscilloscope! Next up: building an amplifier, feeding into a computer via ADC, detecting brainwaves.

  2. Last night’s @hakkavelin mutilation repair work worked perfectly! I now have a rather nice sounding electro-acoustic hurdy gurdy.

    Next steps: wire up the internal microphone, put a plate over the hole in the back, fit the raspberry pi and power supply.
