Here's my homemade wooden box. The fan is in the top of course.
Here's a closeup.
Here's a shot of the camera box closed with the Mogg telescope adapter attached.
This shot shows the CCD.
This image shows the Pontech SV203 which I use as an interface for Mac-based computer control of both the amp-off and exposure lines. The SV203 is an RS232 serial-controlled servo controller. The pins can be used to control the voltages on the control wires.
