Musical Sundial |
|
|
This rather whimsical project monitors the motion of the sun using a pointer to cast a shadow that rotates with the sun. Sensors in an arc detect the position of the shadow, and when a sensor is completely covered by the shadow, electronically generated musical chimes and pips mark the hour of the event, one pip for each hour past. Then &. and then, you get a tune played! But thats not all, on any day when the weathers changeable, with the sun coming and going, appropriate phrases of the "tune" mark the disappearance or re-appearance of the sun. There's no shadow of a doubt that you'll have fun with this musical garden gnomon!
