  1. From the album: Hugh's Stuff

    A bit more progress towards an automated observatory. The motor drive to rotate the dome is now working and the manual control panel is finished. Now need to write the software to hook everything together.

    A bit of a lash up for testing. This is the dome rotation motor driver board. Basically it has a 12 to 24 volt step-up converter for the Leadshine M542 stepper driver, a 12 to 8 volt down converter - power to Arduino boards, a 12 volt to 5 volt converter for sensor power and an Arduino Nano running the motor driver routines. These are based around using Accelstep and the video shows the nice smooth acceleration and deceleration. There is also another board that will have an Arduino Mega to control the Safety Monitor and a Vellesman board for use with LesveDome dome control software.

    This is the dome driver motor. It is a Nema 23 stepper motor with a 4.25:1 planetary gearbox. It is rated for up to 20 Nm torque.
  5. Hi, I'm after some advice on dome slaving. I have a Pulsar 2.2 metre with the dome rotation kit (and two equipment bays) arriving at the end of November and I'd like to slave it to the hand controller rather than buy Maxim DL, SGP etc. Is this possible? My mount is a CGX-L with the standard handset. I use SharpCap Pro to capture images and I am not looking to change my setup drastically nor spend anymore money at this point given what the observatory has cost me. Thanks in advance! Adam
