Dead spark coil (or cis-house on house or JC) is an 18-bit still life. It is composed of two houses that are acting as induction coils to stabilize each other. It is an oscillator in Highlife. One half can eat gliders, but both the top and bottom of that side must have a glider to eat, or else the other side of the house will interfere.
Dead spark coil is the forty-fifth most common still life in Achim Flammenkamp's census, being less common than trans-mirrored R-bee but more common than cis-mirrored hook. It is also the thirty-nineth most common object on Adam P. Goucher's Catagolue.
