- An iPhone (or any such modern phones) with a panorama capture mode
- IR module
- Servo Module
- A couple of rubber bands
- Any IR-based remote control
Take the "x" shaped servo head, and place the iPhone square in the middle of it, tying it up with the couple of rubber bands.
It ends up looking something like this:
Open the camera app, switch to panorama mode, and start the program. Use the remote control to slowly move the iPhone around. Then just go crazy with it.
