I have developed a hardware and software system that displays the equatorial coordinate system of an astronomical telescope mount using the self-made computer PERSEUS-9. The features of this development are as follows. 1) The equatorial mount for the astronomical telescope is made by myself using a motorized rotary stage. 2) I made my own motor controller for an equatorial mount with a simple logic configuration. 3) Display the right ascension, declination and sidereal time of the equatorial mount on my homemade computer PERSEUS-9. As a result, the self-built mount system obtained a slewing speed of up to 1024 times faster than the tracking speed and a positional accuracy of about 1% with respect to the amount of movement. A position display update rate of 1.1 times per second is obtained.

This pattern can be used to make a hacky sack, juggling balls or toys for babies and small children. The pattern is very basic, and you do not need extensive knitting skills to make a hacky sack. The pattern can be varied by using two or three colors for one ball. Stick to simple worsted sized yarn.
