Step 3: Solder 3-axis Accelerometer to Rainbowduino
In order to make it smaller, we need to get a 3-axis acceleration sensor integrated onto the Rainbowduino. A very simple way to integrate is to solder them together directly. You can see the entire soldering process from this video.
With the purpose of a cool appearance, we made two shells for it. One is a 3D printed white shell that looks like a 1990s computer monitor.The other is woven of knitting wool and PP plastic. Of course, if you have a better idea, you can make one by yourself. Sometimes, even a folded paper tray is ok to be a shell.
