  • Very very good scanning capability!! What hardware do you used to control 2 hdd coil??

  • @pointser audio amplifier (from cheap pc desktop speakers)

  • is that all? any updates?

  • @DakotaDaNative thanks for your interest! i tought of a re-design with two speakers with mirrors glued to their cone, driven by a cheap usb soundkard (read: no ac coupling capacitors) and a opamp amplifier to be able to direct the beam to any locaion and let it stay there... caused by missing spare time this isn't done yet
