MASCOT Upgrades
New Camera for MASCOT
After 3 years of successful operation, the firstmayor update of MASCOT has come. The camera Genesis-16 is not longer being sold, and it doesn't have support anymore. Because of that, we decide to change the camera by a new one. The answer was to design and build a own modified version of Audine. Pedro Mardones and Eduardo Bendek design the PCB and the housing metal case for the electronics.Electronic Design
It's basically the Audine design, but with some modifications:- The design was converted to surface mount technology (SMT), to occupy much less area as well as making a double sided PCB much more practical.
- Other significant changes were to adapt the voltage levels to use the KAF-402ME instead the now obsolete KAF-0400.
- Also it was added a PT-100 to have a read measurement the temperature of the CCD

Mechanical Design
The main difference with the original Audine design, is that now the CCD is in a sealed chamber, to avoid condensation. Frost can damage standard CCD's if severe enough and is absolutely devastating to ME series chips as it destroys the microlenses.

The plans of the mechanical design, are available in the the documents section. The next picture shows the MASCOT Audine prototype circuit (it works!).
