I completed my second Wind Harp. This one will be shown at Maker Faire in San Mateo California (Bill's Artbots, thats me!). Strings for the instrument are standard guitar strings, very much adjustable using guitar tuner machines. I wound my own humbucking pickup which is connected to a special preamp I designed using a LT1167 Instrumentation amplifier IC. The pickup is electrically balanced enough not to pick up surrounding AC hum, which was a problem with my other 8 foot contraption on my shed. The quality of sound is impressive.
Information on its construction is at my Maker Faire wind harp page. You can hear my Windsonics album, my best work yet with more to come.
