2 Project description
+
+
+Problem with powerful binoculars is that they are almost unusable +without tripod. High zoom factor also amplifies hand shakes. +
+ ++Tripod is not convenient to carry around. Here is an attempt to design +portable gyro stabilizer that has camera tripod interface. Therefore +cameras and binoculars can be mounted. +
+ + + +
+
+Old computer hard disk platters are used as rotating discs. They are +attached to following disk mount: +

+Discs are rotated by electric motor. Motor is cooled by electric fan. +Motor and fan are powered by 12V that is generated by 3 voltage upstep +converters running in parallel. +

3 Conclusion
++Around half of the stabilizing effect already comes from extra weight +that is added to binoculars by device itself. Rotating platters +contribute also about as much. I had only 2 platters. I'm +contemplating finding more weight to rotate, or even try with old +CD/DVD disks. +
+ ++Unfortunately symmetry is not perfect and small high frequency +vibration is added because of that. +
