The war on 9V batteries

Eliminating the 9V battery for the Astak camera was serious work. The voltage converter ended up gigantic but lighter than a 9V battery.

Although the MAX632 doubles voltage on paper, its output has way too much ripple for the camera. It takes at least 4700uF to eliminate the ripple but since our stock capacitor weighs more than a 9V battery, we have some horizontal bars until the next drive to Silicon Valley.

Replacement parts for the tail gears arrived after 8 days from the notorious "Marks Hobby Warehouse". Nothing beats a relaxing helicopter flight after 8 days terrified of $85 lost. At least it wasn't Euros.
