I've posted this on the EQMOD yahoo group but there may be those interested who are not part of that.
I've managed to get a bluetooth
connection running to control an EQ6 Pro.
I'll summarise what I've done here while it's fresh for the benefit of others
who are trying to do the same.
Equipment - a couple of ebay items and bit's and pieces from my workbench and the local Jaycar store.
- A bluetooth
- An LM7508 voltage regulator
- DB9 male connector
- Micro Bluetooth
adapter for the PC
- A power diode (not essential)
- One small plastic jiffy box from the local electronics store
- Double sided heat trasfer tape (not essential)
All up parts were just over the AU$20.
To confirm pinout's looking at the back of the male DB9 plug connected to the mount with the row of 5 to the top - 1 is top right, 5 is top left, 6 is bottom right and 9 is bottom left.
1 12Vdc - I've soldered a diode into the feed to the regulator. Not essential.
5 - Gnd (Left most of the row of 5 looking at the mount or back of the
6 to the TX pin of the bluetooth
9 to the RX pin of the bluetooth
I've stuck the voltage regulator onto the back of the bluetooth
module with double sided heat transfer tape and brought the GND and output pins down to the back of the 5V and Gnd pins on the bluetooth
module. I removed the 5V pin from the module and then had to replace it, at a guess the hole is not plated through.
Windows XP mapped 2 ports in the Device setup, an Incoming and an Outgoing. I still have not made sense of that but the outgoing one is the one which worked.
I had some problems trying to get EQMOD recognised in the Ascom driver selector, the EQMOD.Telescope driver didn't have any attributes in the profile Explorer. Adding a name seemed to make it visible to the selector. I need to read some more about that as I may now have that right.
I've now had it running from The Sky and also via a very cheap game controller (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=1106477 06075&ssPageName=S\TRK:MEWNX:IT
). That's not fully configured so don't take it as a recommendation for the controller but it does do the basics.
I want to explore some other bluetooth
options, a smallish battery pack and a bluetooth
module for the hand controller so I can run wireless without a PC for simple setup's. Bluetooth
comm's to an Arduino controlling the focusser(s). I'm also wondering how hard it would be to get the output of a USB hub into a bluetooth
transmitter so that camera(s) can be run through the link.
