Initial reporting on the Nokia 3310 Op-Amp was incorrect. Originally it was believed that the circuit contained a 555 Timer vice, the Op-Amp. This circuit explores what it would take to create using a simple 555 timer in an astable configuration. After the 555 timer arms the circuit, a modified Nokia Cellphone triggers the final SCR to detonate on command.
