Introduction: Make an "Air" Drum Kit With Curie

About: A newbie maker working in Maker Collider, a tech startup company in China. I wanna share what we have made with you!

Hi all,

I really like the Freedrum project and decide to do it on my own.

Below is a step by step guide, modified from the VO in the video. By the way, VO is an AI voice, made by Amazon Polly, which speaks in a English accent better than mine :D

Step 1: Get All Things Ready

You will need:

  1. Curie Nano board (Arduino101 can also do the trick, but it is too big for this project.)
  2. a 3.7V lithium battery
  3. a Velcro SD card module
  4. SD card
  5. SD card reader
  6. a drum stick

Step 2: Preparation

You should:

  1. Solder the pin header to the Curie Nano
  2. Insert the SD card into the SD card module
  3. Connect the SD card module to the Curie Nano
  4. Connect lithium battery to the Curie Nano
  5. Put them on the drum stick with Velcro

Step 3: Data Collection

Do some motions to let Curie identify.

Data from Curie IMU will be automatically stored into the SD card.

Step 4: Data Pre-processing

  1. Remove the SD card
  2. Insert the SD card into the SD card reader
  3. Insert it into the computer
  4. Open the motions data stored on the SD card with excel, generate a line graph, truncate the unstable waveform of the front end and the smooth line between each two waveforms, and the last invalid data
  5. Save the file!!!!

The pre-processed data will be put into QriNeuronPipeline - a feature extraction software by Maker Collider. Then generate several new csv files into the SD card.

Step 5: Curie Learning

Unplug the SD card and insert the SD card module again.

Curie will read the data from SD card and start learning!

Step 6: Pair With IPad/iPhone

  1. Open the GarageBand application on iPad or iPhone
  2. Choose Bluetooth MIDI Devices Item in Advanced Settings, and choose Curie to pair.

Now, you are ready to play the "Air" Drum Kit!

Enjoy the beat! :)
