Swell Dials

This is an arduino project to visualise ocean data wave height/swell period & local wind from any surfing location on magicseaweed

Here is the illustrator file for the gauges that im planning to be laser engraved https://www.dropbox.com/s/kqlo390j8pi5dgo/guages.ai?dl=0

To test the design I printed the dials onto t-shirt transfer paper and ironed them on to some 18mm MDF that i had lying around.

I also added a LED to blink once optimum surfing conditions are happening

Rear view of the mdf showing cutouts for the 3 x Tower Pro micro 9g servos, the wind direction indicator is a FSR90 continuous servo to allow 360 rotation.

It is still in development and ill update progress here
