Subject: Making your own GPUSB


Milton,


Is there a diagram for making a USB version like the GPUSB? I might be missing something, but I just see reference to a camera connector cable. I have to give my friends GPUSB cable back after testing. So either I buy one, or make one. I have an Imaging Source Firewire camera.

On a side note. you can also build your own ST4 Guider board and then  

use that instead of the GPUSB : cost would be less than $10 for parts.

The FireFly MV and Chameleon has 4 GPIO pins via a BM07B-SRSS-TB  

connector,  so you could connect the BM07B-SRSS-TB to the ST4.


Then you have one cable to the camera, and the camera connects to the  

ST 4 Port.


I use that all the time now. So I have one FW800 cable coming from my  

Mac , which is connected to the Grasshopper 2 (it has 2 FW 800 ports),  

and then I daisy chain a FW800 cable from the main imaging Grasshopper  

2 to my guide camera (either a FW400 Flea or now my old Grasshopper 1  

camera)  and then the ST4 port is connected to the guide camera. So a  

single cable to 2 Cameras and the mount for imaging, guiding and mount  

control. For me, this is especially important during the winter to  

reduce the number of stiff cables I have to deal with (at -40°C all  

cables are basically plastic rods).


See page 109 and 110 of the Astro IIDC manual for more information on  

Hardware modifications.

You would connect the computer to the mount using a GPUSB from  

Shoestring Astronomy.  They're reasonably priced, and you can get  

different cables for the various mounts that support ST-4 signals.

Wonderful!

I have a Mac and I'm trying the try version of Astro_IIDC before to  

buy it. When arrive the two FireFly I've purchase i'll try to use  

one of them for autoguiding my mount.

By the way, I should connect the camera to the computer and the  

computer to the mount, shouldn't I? There's not any direct way to  

connect the camera to te ST4 port, isn't it?

Hi, everybody!

I presume you don't use FlyCapture to manage this camera, but

Astro_IIDC.


Yes. FlyCapture does not run under OS X.


I ask: it works all right or you need some extra software?


Yes, their USB 2 camera support the IIDC protocol so they work  

fine -

all you need is a Astro IIDC on the Mac.
