The project sends a midiNote 127 with the velocity 127 when you touch the metal pin by sensing capacitive touch. When the prototype was done on a solderless breadboard it was a bit fragile. Koka didn’t want to wait for a PCB to be made, so he spent $1.40 at IKEA on a jar. He drilled a few holes in the top and made a secure enclosure for his project.
Here’s a nifty test video by forum user Potatotron
This module is designed for Teensy boards and has the proper signal voltages for use with the audio library. It uses the MAX9814 – a high quality, now noise, pre-amp chip. This module is designed to work directly with the Teensy analog inputs – you don’t need the audio shield to use this module.
If you are doing any project that requires a microphone and a Teensy, go buy this now.
Ranjit Bhatnagar created a stone sound sculpture that responds to the settling of its stones and the weather by playing sounds. This beautiful sculpture uses sensors for pressure, humidity, temperature, and barometric pressure to collect data and send it to a drone synthesizer, making the sculpture feel alive with sound.
We published a video on with some tips on soldering header pins on to your Teensy board.
A couple of tips to remember when soldering header pins to your board:
1 – You MUST solder the pins. Setting the Teensy on the header pins without completing the soldering will not work.
2 – Use a breadboard to keep the pins straight and stable when soldering
3 – Leave the soldering iron on the pad for a moment after you solder. This will bring all the components – the pad, the header pin, and the solder up to the same temperature so they will cool together to form a proper molecular bond.
