Five, open source skis

The original idea of ​​the work was to make an open source snowboard ski. This snowboard recognizes the action and emits different sound effects. For example, when you slide the snowboard and get on the pole, it will emit a special effect sound of ci... For example, when you do ollie, you will make a duang sound.

The implementation concept is based on the detection of the action of the gyroscope to make the snowboard. Use a small nano board to make an mp3 expansion board. Use sd expansion board to do music storage built-in music decoding chip decoding. Finally, the Bluetooth module is matched to the Bluetooth headset.

In fact, the name should be called open-air snowboard anti-slip stickers. In the implementation, all the hardware only needs to be embedded in a snowboard anti-slip sticker, so that no matter what snowboard, only the snownow open-air anti-slip sticker is attached. It has become an open source ski board. This will also be beneficial to future commercial development. (And explain to everyone that the non-slip sticker is not just a decoration. It is a weapon that acts as an anti-slip when you stand on the holder.)

There are two sets of power supply systems, one is a solar power supply system, the solar panels are embedded in the anti-slip stickers, and the solar cells are used to continuously charge the batteries. The other is a wireless charging system for perfect waterproofing.
