Kevin made a kill telescope controller. It is a simple Arduino-based device for interfacing with a motorized telescope mount. This would be a fairly simple device to make. How big is the interest in something like this? Maybe Pax Instruments should manufacture one.

There’s many complex systems for automatically pointing a telescope at an object in the sky, but most of them are too expensive for the amateur astronomer. [Kevin]’s Arduino ST4 interface lets you connect your PC to a reasonably priced motorized telescope mount, without ripping it apart.
