Today I am going to build an interface box to allow PHD style autoguiding input from a laptop to be sent directly to the Computstar controller interface.
I am using information found on the Computstar Fanpage.
First of all there is this SBIG Autoguider interface schematic by Dennis Borgman:
And Rod Pommier shared some wonderful instructions in this PDF: How To Autoguide The Compustar
So here is the parts list needed for the Compustar Autoguiding Relay Interface Box
| Quantity | Part |
| 1 |
RJ-11 cable with modular jacks
|
| 1 | Plastic electrical container box |
| 4 |
Radio Shack 275-241A 5Vrelay switches
(275-240A relays also work)
|
| 2 | 1k ohm potentiometers |
| 1 |
Small circuit board
|
| 1 |
DB-9 cable with male connector pins
|
So off to the store to get some parts…
