Apology in advance if i sound silly.   I tend to star-hop within a constellation, or two local constellations, otherwise it's quicker to go outside and move it manually. I wanted to put all the electronics including the battery into a single box attached to the mount.Regarding the component you are looking for, as far as I understand, a latching relay would do the job.To continue the saga, I now have guiding, focusing and remote exposure all working on the Arduino. point See below.   point To make the experience fit your profile, pick a username and tell us what interests you. point

Even 32x is only a small jump and I've read elsewhere that the standard motors won't take 800x. point

Also, the pins (excepted GND) can be reassigned in software by editing the arduino firmware.Maybe I should make this an option of the ASCOM driver.Can someone confirm that I need to swap the connections over on the RJ12 socket as they do not correspond to the socket on the Star Adventurer? point There are a lot of files on github and some are obviously important while others are documentation or windows specific. point If so, you could deduce the pinout of your mount and modify the connections to the optocoupler accordingly.I have assumed that 'GND, PIN2, PIN3, PIN4, PIN5' on your diagram are referring to GND, D2, D3, D4, D5 on the Arduino, otherwise I have found the project fairly straightforward so far.Apparently, mounts from different manufacturers use different pin assignments, it seems that there is no standard for this.I guess that even if you don't connect the wires right, you should be safe since the connection between the arduino and the mount is optically isolated.
  An attendance system based on Arduino and RFID reader which will save attendance data in real-time to Google spreadsheet. You could drill two small holes into the case. The purpose of this project is to connect a telescope to a computer through the mount guide port (ST-4 port) using an arduino in order to cheaply add GOTO and autoguiding capabilities. Hi Kevin, One of the things I want to do is really remote control.

The video below shows this tool chain in action.This combination gives a resolution of around 24 ticks per arc second when reading 4x via the encoder IC.This is plenty for provide tracking GOTO and tracking accuracy. Ce projet utilise les cartes de la série blindage Arduino. Serial commands going through and Arduino responds back with ok# for ra-#,ra+# etc. I would be very interested in seing some pictures :)I would love remote control as well, to get rid of all the cables waiting for you to trip over in the dark night.One year ago I started to experiment with bluetooth connection (HC-05 bluetooth to serial), and I got it working, but I never completed the project, mainly due to a lack of time.

The ST-4 Port is easy to add to "low cost" motorized mounts like the EQ4 or EQ5, and the operation requires minimal modification to your shiny mount. I'm SteveBz in this discussion:You can see there are a couple of references to this project and you can see my effort at the Ardiuno. In fact a single ten-pin socket might do the trick or even a vga socket and cable. It supports Equatorial Mounts (GEM, Fork, etc.) point point The Arduino Mega 1280 is housed in a box on the telescope. Portable. point 2.     point point
