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

If any questions, please feel free to comment below or contact us!

Step 1: Get All Things Ready

You will need:

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

Step 2: Preparation

You should:

Solder the pin header to the Curie Nano
Insert the SD card into the SD card module
Connect the SD card module to the Curie Nano
Connect lithium battery to the Curie Nano
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

Remove the SD card
Insert the SD card into the SD card reader
Insert it into the computer
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
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.
