The paper presents a practically realized system of electronic programmable detonator designed for tandem systems. The presented layout was implemented on the basis of micro-controllers using RISC architecture. The detonator is equipped with a fast precursor excitation system and can be programmed for the required delay time of the detonation of the main charge in the range from a few to several hundred µs. The paper presents the results of laboratory preliminary tests of the implemented system. Thanks to the possibility of delay time programming, the system has a wide range of practical applications also during shooting tests.
