Wifi Skywatcher Synscan V3/V4 Telescope Link by clifton2

Last crawled date: 3 years ago

Following on from my Bluetooth Synscan interface I have now created a WiFi version which offers a more stable connection over greater distances.
External WiFi controller for the Synscan hand controller.
Allows remote connection via the handset serial port to read the position of the scope and to slew it to objects from Stellarium or Stars on a Mac via the Indi server drivers.
The 3 low cost modules inside all available from Gearbest or ebay or similar sites, only limited programming of the ESP device required. One spare ST4 cable required as it has the full six wires for powering the modules from the handset and will require one end to be cut off.
Parts Required:
spare ST4 cable
NodeMCU ESP8266 WiFi module https://www.gearbest.com/transmitters-receivers-module/pp_366523.html
Power convertor module http://www.gearbest.com/development-boards/pp_51010.html?wid=21
RS232 to TTL convertor https://www.ebay.co.uk/itm/2Pcs-Com-Serial-Board-Max232cse-Transfer-Rs232-To-Ttl-Converter-Module-Ic-New-U/132187217126?hash=item1ec6f8dce6:g:GJMAAOSwKOJYIEc4
Various nylon pillars and screws to mount the board inside the box.
Full details in PDF included in the things files, please follow very carefully.
If using Stars with the Indi Server on a Mac you can choose Celestron Nexstar telescope mount from the drivers and you can connect directly at the IP address on port 2323. You will get an error right at connection but after that it runs perfect.
