The project has several hardware configurations including 2 or 4 line LCD display, software or hardware clock.
The hardware clock is an add on, mine came from Futurlec and is their DS1307. It costs about AUS$10. The LCD displays should be HD44780 compatible - most are.
The unit has open collector drives for azimuth and elevation control and brake. These may drive other units directly (e.g. the YAESU G-5500 without the expensive data control unit) or via relays, home brew motor drive systems.
The shack unit has internal calculations for the sun and the moon. These are accurate to about 0.1 degree. There is no need to use a computer for control when tracking the moon or sun, but some may choose to using either my "Remote.exe" program or Doug VK3UM's Autotrack. The "Remote.exe" program also allows internet control using a WIZ-110SR serial to IP interface.
The unit tracks satellites very well and for those who have a mechanical system that will invert the antenna the “Remote”
Software supports Flip Mode.
In four line version the readout provides AZ/EL of sun or moon and antenna, declination, doppler, local and UTC time. In two line displays the screen indicates AZ/EL of the antenna and AZ/EL of the object. It can be set to show time and/or doppler on the basis of an interrupted display of the AZ/EL of the object.
NEW: Versions for the 2 line and 4 line display with hardware clock now support a PWM mode and an H-bridge (using I2C) mode to achieve auto adjustment of the speed of the rotator system at the end of a move. The I2C hbridge system is still to be fully tested, I will work with any person using this mode to ensure a good result. Both solutions require some external hardware. Send me an email if you are interested in BETA testing this one.
“Version 12.6 Four” fixes hysteresis bug at Nth as does Version 12.1e for the 2 line display. See Readme1st here.
