A new chaotic jerk circuit has been realised using a current‐tunable technique. Based on traditional nonlinearity of a signum function, newly smooth transitions from a balanced double‐scroll chaotic jerk attractor to an unbalanced double‐scroll and eventually to either a left‐half or a right‐half single‐scroll chaotic jerk attractor are experimentally revealed using either a negative or a positive adjustable current source I 0 , respectively. Current‐tunable bifurcations are demonstrated. A plot of the largest Lyapunov exponent resembles a symmetrically balanced image centred at I 0 = 0.
